    Phylogeny and classification of the Old World Emberizini (Aves, Passeriformes)2008Ingår i: Molecular Phylogenetics and Evolution, ISSN 1055-7903, E-ISSN 1095-9513, Vol. 47, nr 3, s. 960-973Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The phylogeny of the avian genus Emberiza and the monotypic genera Latoucheornis, Melophus and Miliaria (collectively the Old World Emberizini), as well as representatives for the New World Emberizini, the circumpolar genera Calcarius and Plectrophertax and the four other generally recognized tribes in the subfamily Emberizinae was estimated based on the mitochondrial cytochrome b gene and introns 6-7 of the nuclear ornithine decarboxylase (ODC) gene. Our results support monophyly of the Old World Emberizini, but do not corroborate a sister relationship to the New World Emberizini. Calcarius and Plectrophenax form a clade separated from the other Emberizini. This agrees with previous studies, and we recommend the use of the name Calcariini. Latoucheornis, Melophus and Miliaria are nested within Emberiza, and we therefore propose they be synonymized with Emberiza. Emberiza is divided into four main clades, whose relative positions are uncertain, although a sister relation between a clade with six African species and one comprising the rest of the species (30, all Palearctic) is most likely. Most clades agree with traditional, morphology-based, classifications. However, four sister relationships within Emberiza, three of which involve the previously recognized Latoucheornis, Melophus and Miliaria, are unpredicted, and reveal cases of strong morphological divergence. In contrast, the plumage similarity between adult male Emberiza (formerly Latoucheornis) siemsseni and the nominate subspecies of the New World Junco hyemalis is shown to be the result of parallel evolution. A further case of parallel plumage evolution, between African and Eurasian taxa, is pointed out. Two cases of discordance between the mitochondrial and nuclear data with respect to branch lengths and genetic divergences are considered to be the result of introgressive hybridization.

    Morphological, vocal and genetic divergence in the Cettia acanthizoides complex (Aves : Cettiidae)2007Ingår i: Zoological Journal of the Linnean Society, ISSN 0024-4082, E-ISSN 1096-3642, Vol. 149, nr 3, s. 437-452Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We used morphological, vocal and molecular (one mitochondrial and two nuclear loci) data to re-evaluate the taxonomic status of the taxa acanthizoides, concolor, and brunnescens in the Cettia acanthizoides (J. Verreaux, 1871) complex. We conclude that all three are valid taxa, and that acanthizoides of China and concolor of Taiwan are best treated as conspecific, whereas brunnescens of the Himalayas is better considered as a separate species. The degree of morphological, vocal, and genetic differentiation is variably congruent among all taxa; the recently separated acanthizoides and concolor differ slightly in plumage and structure but are indistinguishable in vocalizations, whereas the earlier diverged brunnescens and acanthizoides/concolor differ only slightly more in morphology but to a much greater degree in vocalizations. We stress the essential nature of taxonomic revisions as a prerequisite for the biodiversity estimates required for conservation planning.

    Species delimitation based on multiple criteria: the Spotted Bush Warbler Bradypterus thoracicus complex (Aves : Megaluridae)2008Ingår i: Zoological Journal of the Linnean Society, ISSN 0024-4082, E-ISSN 1096-3642, Vol. 154, nr 2, s. 291-307Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We demonstrate the importance of using multiple criteria in species delimitations, whatever the conceptual base for species delimitation. We do this by studying plumage, biometrics, egg coloration, song, mitochondrial DNA and habitat/altitudinal distribution in the Spotted Bush Warbler Bradypterus thoracicus (Blyth) complex, and by conducting playback experiments. Taxa that we suggest are best treated as separate species [B. thoracicus (Blyth), B. davidi (La Touche) and B. kashmirensis (Sushkin)] differ in most or all of these aspects, particularly in song and mitochondrial DNA, while those that we treat as subspecies (suschkini) or synonyms (przevalskii) differ slightly and only in morphology.

    Repellency of methyl jasmonate to Ixodes ricinus nymphs (Acari: Ixodidae)2007Ingår i: Experimental & applied acarology, ISSN 0168-8162, E-ISSN 1572-9702, Vol. 42, nr 3, s. 209-215Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In our search for tick repellents of plant origin, to be used as alternatives to commercial arthropod repellents, we investigated the effect of the well known plant signaling compound methyl jasmonate (MJ) using nymphs of the tick Ixodes ricinus. In laboratory tests, pieces of cloth with MJ at 0.075, 0.15, 0.30 and 0.75 mg/cm2 yielded increasing repellencies against the nymphs: 57%, 71%, 92% and 99%, respectively, of the nymphs did not cling to the cloth. Repellency of MJ was also investigated in a tick-infested woodland area in central Sweden. Cotton flannel cloths sprayed with 0.05, 0.1 or 0.2 mg/cm2 MJ dissolved in acetone were dragged over the ground vegetation. The numbers of nymphs on the treated cloths were significantly lower than those on the untreated cloth. Thus, MJ has, at the concentrations tested, significant repellent activity against I. ricinus nymphs.

    Repellency of MyggA® Natural spray (para-menthane 3, 8-diol) and RB86 (neem oil) against the tick Ixodes ricinus (Acari: Ixodidae) in the field in east-central Sweden2006Ingår i: Experimental & applied acarology, ISSN 0168-8162, E-ISSN 1572-9702, Vol. 40, nr 3-4, s. 271-277Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In the field in south-central Sweden, we tested by randomised, standardised methodology the potential anti-tick repellent activity of two concentrations of MyggA® Natural spray (containing PMD) (4.2 and 3.2 g/m2) and one of RB86 (with 70% neem oil containing azadirachtin)(3 g/m2) to host seeking nymphs of Ixodes ricinus. Each substance was applied separately to 1 m2 cotton flannel cloths. Nymphal ticks on the cloths, pulled over the vegetation, were recorded at 10-m stops. Nymphal numbers recorded differed significantly between treated cloths [4.2 or 3.2 g MyggA® Natural spray/m2 and 3 g RB86/m2] and the untreated control (df = 3, χ2 = 112.74, P < 0.0001). Nymphal numbers also differed significantly among collectors (df = 3, χ2 = 15.80, P < 0.001). Repellency of treated cloths, i.e., 4.2 or 3.2 g MyggA® Natural spray/m2 and 3 g RB 86/m2 declined from day 0 (i.e. the day of impregnation) to day 3 after impregnation from 77 to 24%, 58 to 16% and 47 to 0.5%, respectively. This study suggests that all three treatments have significant repellent activities against I. ricinus nymphs.

    Build-up of the Himalayan avifauna through immigration: A biogeographical analysis of the Phylloscopus and Seicercus warblers2007Ingår i: Evolution, ISSN 0014-3820, E-ISSN 1558-5646, Vol. 61, nr 2, s. 324-333Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Himalayan mountain range is one of the most species-rich areas in the world, harboring about 8% of the world's bird species. In this study, we compare the relative importance of immigration versus in situ speciation to the build-up of the Himalayan avifauna, by evaluating the biogeographic history of the Phylloscopus/Seicercus warblers, a speciose clade that is well represented in Himalayan forests. We use a comprehensive, multigene phylogeny in conjunction with dispersal-vicariance analysis to discern patterns of speciation and dispersal within this clade. The results indicate that virtually no speciation has occurred within the Himalayas. Instead, several speciation events are attributed to dispersal into the Himalayas followed by vicariance between the Himalayas and China/Southeast Asia. Most, perhaps all, of these events appear to be pre-Pleistocene. The apparent lack of speciation within the Himalayas stands in contrast to the mountain-driven Pleistocene speciation suggested for the Andes and the East African mountains.

    Phylogeny of Catenulida and support for Platyhelminthes2008Ingår i: Organisms Diversity & Evolution, ISSN 1439-6092, E-ISSN 1618-1077, Vol. 8, nr 5, s. 378-387Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Molecular studies have shown that Platyhelminthes is polyphyletic, placing Rhabditophora within Lophotrochozoa, whereas Acoela and Nemertodermatida are separate early bilaterian branches. However, there has been little evidence to support the position of Catenulida, a group that was traditionally classified within Platyhelminthes. In Ehlers' pioneering cladistic system of the Platyhelminthes they were placed as the earliest clade. Other morphologists have considered the Catenulida as an early bilaterian clade separate from Rhabditophora, a position that was supported in an early molecular study. Subsequent molecular phylogenetic studies, which placed Catenulida as the sister group of Rhabditophora with no or low branch support, included 18S rDNA data from only one or two catenulid species. The aims of the present study were (1) to test the putative sister-group relationship of Catenulida and Rhabditophora by improving the taxon sampling of molecular data spanning a larger part of catenulid taxonomic diversity and (2) to provide a phylogenetic framework for the systematization of Catenulida. Twelve catenulid species were sampled around Sweden. Both the 18S rDNA gene and the 28S rDNA gene were sequenced and analysed in a Metazoa-wide data set within parsimony and Bayesian frameworks. The results unambiguously support Catenulida as the sister group of Rhabditophora within Lophotrochozoa. Parsimony-based inferences about the common ancestor of Catenulida and Rhabditophora are presented. A definition of the name Platyhelminthes is suggested.

    The cynipoid genus Paramblynotus: Revision, phylogeny, and historical biogeography (Hymenoptera : Liopteridae)2007Ingår i: Bulletin of the American Museum of Natural History, ISSN 0003-0090, E-ISSN 1937-3546, nr 304, s. 3-151Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The genus Paramblynotus is the most species-rich genus of the so-called macrocynipoids, the large cynipoid parasitoids of wood-boring and cone-boring insect larvae. The species range in size from some of the largest to the smallest macrocynipoids, comparable in size to microcynipoids. Paramblynotus members occur on all continents except Europe and Australia, with most species being tropical or subtropical. The biology is poorly known but a few observations indicate that the species are parasitoids of beetle larvae. In this monographic revision of the genus, we present a species-level cladistic analysis based on qualitative and quantitative features of the external morphology. For analysis of quantitative features, we present for the first time a novel coding method, the method of Finite Mixture Coding (FMC) based on k-means clustering, or FMCK. The new method is similar to the FMC method proposed by previous authors in that they both generate codes (character states) for phylogenetic analysis as the direct output of a statistical procedure, thus avoiding the subdivision of quantitative data into discrete states on the basis of arbitrary criteria as with other coding methods. Through incorporating finite mixture analysis and likelihood estimation as used in FMC and k-mean cluster analysis for a priori statistical modeling of component distributions, FMCK is advantageous over FMC in that it can be implemented using readily available statistic programs with k-mean cluster analysis, such as STATISTICA, MINITAB or SYSTAT, available on both PC and Macintosh platforms. We were able to identify 8 quantitative characters among 23 as useful for cladistic analysis by using the new coding method. In total, our character matrix has 132 coded characters. The phylogenetic analysis indicates that species of the previously recognized genus Decelleu form a monophyletic group deeply nested within Paramblynotus. Decellea is therefore synonymized with Paramblynotus, which is separated into seven monophyletic species groups: the virginianus, scaber, ynngambicolars, nigricornis, apeosus, ruficollis, and punclulalus groups. Based on the phylogeny, we reconstruct the historical biogeography of the liopterid subfamily Mayrellinae, consisting of the genera Paramblynotus and Kiefferiellu, using dispersal-vicariance analysis in combination with palaeoenvironmental data. The results suggest that the subfamily originated in the Northern Hemisphere and then expanded its distribution early by way of the Bering area. The divergence between Puramblynotus and Kiefferiellu was apparently associated with the formation of the Rocky Mountains about 50 million years ago. An early Paramblynotus lineage dispersed to Africa from the eastern Palearctic by way of Arabia, and it subsequently diversified along with montane forests in Africa. The relatively high diversity of Paramblynotus in Southeast Asia is considered to be partly caused by the frequent sea level changes since late Oligocene (29 Ma), which drastically changed the land configuration of this area. We end this paper with a taxonomic revision of the genus Paramblynotus, with a total of 92 species treated, including 72 described as new and 20 previously known, of which 18 are redescribed. Keys to the species groups as defined in this paper and to all known species of each species group are provided. For all species, the available information on their biology and distribution are summarized.

    Triatoma ryckmani (Hemiptera: Reduviidae) in the epiphyte Tillandsia xerographica (Bromeliaceae) in the semiarid region of Guatemala2004Ingår i: Journal of Medical Entomology, ISSN US ISSN 0022-2585, Vol. 41, nr 3, s. 321-323Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    For the first time, the reduviid bug Triatoma ryckmani Zeledón and Ponce (Hemiptera; Reduviidae) was recorded to inhabit the epiphyte Tillandsia xerographica Rohweder (Bromeliaceae) in the semiarid region of Guatemala. These bromeliads grow mainly in drought-resistant trees with rough bark such as Pereskia lychnidiflora (Cactaceae). In our study site, we investigated 30 T. xerographica, and 53 specimens of T. ryckmani were found. Most T. ryckmani (68.5%) were unfed. Ants (Formicidae) were the predominant (92.2%) insect taxon in T. xerographica. Other insects such as Blattidae (3.0%), Reduviidae (T. ryckmani: 2.5%), Blaberidae (2.2%), Gryllidae (0.1%), and Acrididae (0.1%) were recorded in the bromeliads. T. xerographica is illegally commercialized without previous inspection. This may cause accidental introduction of T. ryckmani to houses and to other countries.

    Dispersion and colonization of Triatoma ryckmani (Hemiptera: Reduviidae) in artificial environments in a semiarid region of Chagas disease endemic area in Guatemala2004Ingår i: Acta Tropica, Vol. 91, s. 145-151Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The colonization capacity and dispersal of sylvatic populations of Triatoma ryckmani Zeledón and Ponce were investigated by means of experimental chicken coops installed within the semiarid region in the Department of El Progreso, Guatemala. In the four artificial habitats a total of 672 T. ryckmani was found as well as two males of T. dimidiata (Latreille). Triatomine densities were not the same in the four chicken coops. From one chicken coop 53.4% (359) of the triatomines were collected. Full colonization, i.e. all stages from egg to adult found at the same time, took place in the fourth month after the first female’s arrival. High dispersal and colonization capacity of T. ryckmani was evident; adult dispersal occurs mainly during the dry and coolest season (November–February). The overall female/male sex ratio was 2:1; more females than males were found throughout the year. Most of the triatomines in the shelter inside the chicken coops were found on the northern (43%; with less heat and sunlight) and eastern side (35%; more windy). This is the first report on the colonization capacity and population dynamics of T. ryckmani in artificial habitats in a Chagas disease endemic area of Central America.

    Bayesian Phylogenetics and the Evolution of Gall Wasps2004Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    This thesis concerns the phylogenetic relationships and the evolution of the gall-inducing wasps belonging to the family Cynipidae. Several previous studies have used morphological data to reconstruct the evolution of the family. DNA sequences from several mitochondrial and nuclear genes where obtained and the first molecular, and combined molecular and morphological, analyses of higher-level relationships in the Cynipidae is presented. A Bayesian approach to data analysis is adopted, and models allowing combined analysis of heterogeneous data, such as multiple DNA data sets and morphology, are developed. The performance of these models is evaluated using methods that allow the estimation of posterior model probabilities, thus allowing selection of most probable models for the use in phylogenetics. The use of Bayesian model averaging in phylogenetics, as opposed to model selection, is also discussed.

    It is shown that Bayesian MCMC analysis deals efficiently with complex models and that morphology can influence combined-data analyses, despite being outnumbered by DNA data. This emphasizes the utility and potential importance of using morphological data in statistical analyses of phylogeny.

    The DNA-based and combined-data analyses of cynipid relationships differ from previous studies in two important respects. First, it was previously believed that there was a monophyletic clade of woody rosid gallers but the new results place the non-oak gallers in this assemblage (tribes Pediaspidini, Diplolepidini, and Eschatocerini) outside the rest of the Cynipidae. Second, earlier studies have lent strong support to the monophyly of the inquilines (tribe Synergini), gall wasps that develop inside the galls of other species. The new analyses suggest that the inquilines either originated several times independently, or that some inquilines secondarily regained the ability to induce galls. Possible reasons for the incongruence between morphological and DNA data is discussed in terms of heterogeneity in evolutionary rates among lineages, and convergent evolution of morphological characters.

    Abstract [en]

    The recent development of Bayesian phylogenetic inference using Markov chain Monte Carlo (MCMC) techniques has facilitated the exploration of parameter-rich evolutionary models. At the same time, stochastic models have become more realistic (and complex) and have been extended to new types of data, such as morphology. Based on this foundation, we developed a Bayesian MCMC approach to the analysis of combined data sets and explored its utility in inferring relationships among gall wasps based on data from morphology and four genes (nuclear and mitochondrial, ribosomal and protein coding). Examined models range in complexity from those recognizing only a morphological and a molecular partition to those having complex substitution models with independent parameters for each gene. Bayesian MCMC analysis deals efficiently with complex models: convergence occurs faster and more predictably for complex models, mixing is adequate for all parameters even under very complex models, and the parameter update cycle is virtually unaffected by model partitioning across sites. Morphology contributed only 5% of the characters in the data set but nevertheless influenced the combined-data tree, supporting the utility of morphological data in multigene analyses. We used Bayesian criteria (Bayes factors) to show that process heterogeneity across data partitions is a significant model component, although not as important as among-site rate variation. More complex evolutionary models are associated with more topological uncertainty and less conflict between morphology and molecules. Bayes factors sometimes favor simpler models over considerably more parameter-rich models, but the best model overall is also the most complex and Bayes factors do not support exclusion of apparently weak parameters from this model. Thus, Bayes factors appear to be useful for selecting among complex models, but it is still unclear whether their use strikes a reasonable balance between model complexity and error in parameter estimates.

    Accounting for phylogenetic uncertainty in biogeography: A Bayesian approach to dispersal-vicariance analysis of the thrushes (Aves2008Ingår i: Systematic Biology, ISSN 1063-5157, E-ISSN 1076-836X, Vol. 57, nr 2, s. 257-268Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The phylogeny of the thrushes (Aves: Turdus) has been difficult to reconstruct due to short internal branches and lack of node support for certain parts of the tree. Reconstructing the biogeographic history of this group is further complicated by the fact that current implementations of biogeographic methods, such as dispersal-vicariance analysis (DIVA; Ronquist, 1997), require a fully resolved tree. Here, we apply a Bayesian approach to dispersal-vicariance analysis that accounts for phylogenetic uncertainty and allows a more accurate analysis of the biogeographic history of lineages. Specifically, ancestral area reconstructions can be presented as marginal distributions, thus displaying the underlying topological uncertainty. Moreover, if there are multiple optimal solutions for a single node on a certain tree, integrating over the posterior distribution of trees often reveals a preference for a narrower set of solutions. We find that despite the uncertainty in tree topology, ancestral area reconstructions indicate that the Turdus clade originated in the eastern Palearctic during the Late Miocene. This was followed by an early dispersal to Africa from where a worldwide radiation took place. The uncertainty in tree topology and short branch lengths seems to indicate that this radiation took place within a limited time span during the Late Pliocene. The results support the role of Africa as a probable source area for intercontinental dispersals as suggested for other passerine groups, including basal diversification within the songbird tree.

    High Levels of Hybridization between Molecular Forms of Anopheles gambiae from Guinea Bissau2008Ingår i: Journal of medical entomology, ISSN 0022-2585, E-ISSN 1938-2928, Vol. 45, nr 6, s. 1057-1063Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In the malaria vector Anopheles gambiae Giles sensu stricto, two molecular forms denoted M and S are considered units of incipient speciation within this species. Very low hybrid frequencies and significant genetic differentiation have been found in sympatric M- and S-form populations, We studied the molecular form composition and the degree of genetic differentiation at 15 microsatellites in two samples of An. gambiae collected ill two consecutive years from Bissau, Guinea Bissau. High frequencies of M/S hybrids (19-24%) were found in this area. Coincidently, very low levels of genetic differentiation were detected between forms when analysis involved microsatellites mapped at chromosome-3 (mean F-st 0.000-0.002). The single exception was the X-linked AGXH678, for which high differentiation was measured (F-st 0.158-0.301). This locus maps near the centromere of chromosome X, a low recombination region in which selection is likely to promote divergence between M and S forms. These results strongly suggest that the degree of isolation between M and S forms, considered the units of incipient speciation within An. gambiae, is not homogenous throughout the species distribution range.

    Phylogeography of Indonesian and Sino-Himalayan region bush warblers (Cettia, Aves)2006Ingår i: Molecular Phylogenetics and Evolution, ISSN 1055-7903, E-ISSN 1095-9513, Vol. 41, nr 3, s. 556-565Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We present a hypothesis for the phylogeny and phylogeography of a group of bush warblers in the genus Cettia, based on parts of the mitochondrial Cytochrome b gene and the nuclear myoglobin intron II (in all similar to 1.7 kb). Ancestral areas were reconstructed by dispersal-vicariance analysis and constrained Bayesian inference. The results suggest that the insular taxa in the Cettia vulcania group are most closely related to Cettia flavolivacea, and originated from a dispersal by an ancestral population in the Himalayas towards the south, to the Sunda region. From this population, a second dispersal along a different route colonized China and northern Vietnam. Hence, the Chinese taxon intricata and Vietnamese oblita, currently allocated to C. flavoliuacea, are more closely related to the vulcania group than to the other taxa in the flavolivacea group, and we propose that they be treated as conspecific with C vulcania, restricting C. flavolivacea to Myanmar and the Himalayas.

    Acoelomorph flatworms are deuterostomes related to Xenoturbella2011Ingår i: Nature, ISSN 0028-0836, E-ISSN 1476-4687, Vol. 470, nr 7333, s. 255-260Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Xenoturbellida and Acoelomorpha are marine worms with contentious ancestry. Both were originally associated with the flatworms (Platyhelminthes), but molecular data have revised their phylogenetic positions, generally linking Xenoturbellida to the deuterostomes(1,2) and positioning the Acoelomorpha as the most basally branching bilaterian group(s)(3-6). Recent phylogenomic data suggested that Xenoturbellida and Acoelomorpha are sister taxa and together constitute an early branch of Bilateria(7). Here we assemble three independent data sets-mitochondrial genes, a phylogenomic data set of 38,330 amino-acid positions and new microRNA (miRNA) complements-and show that the position of Acoelomorpha is strongly affected by a long-branch attraction (LBA) artefact. When we minimize LBA we find consistent support for a position of both acoelomorphs and Xenoturbella within the deuterostomes. The most likely phylogeny links Xenoturbella and Acoelomorpha in a clade we call Xenacoelomorpha. The Xenacoelomorpha is the sister group of the Ambulacraria (hemichordates and echinoderms). We show that analyses of miRNA complements(8) have been affected by character loss in the acoels and that both groups possess one miRNA and the gene Rsb66 otherwise specific to deuterostomes. In addition, Xenoturbella shares one miRNA with the ambulacrarians, and two with the acoels. This phylogeny makes sense of the shared characteristics of Xenoturbellida and Acoelomorpha, such as ciliary ultrastructure and diffuse nervous system, and implies the loss of various deuterostome characters in the Xenacoelomorpha including coelomic cavities, through gut and gill slits.

    Copulatory organ musculature in Childia (Acoela) as revealed by phalloidin fluorescence and confocal microscopy2006Ingår i: Tissue & Cell, ISSN 0040-8166, E-ISSN 1532-3072, Vol. 38, nr 4, s. 219-232Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Copulatory organs of eight species of the monophyletic taxon Childia were investigated in detail, using phalloidin fluorescence method and confocal microscopy. Childia species were shown to have one, two or several tubular stylets, conical to cylindrical in shape, composed of few to numerous needles. The musculature varied greatly, from the absence of seminal vesicle to extensively developed seminal vesicles with several additional types of specialized muscles. Ten copulatory organ characters were coded and mapped on the total evidence tree. The data obtained permitted to follow the evolution of the Childia stylet and to demonstrate that the structure of the stylet apparatus is. largely consistent with the phylogeny of the group (CI = 0.75). Possible function of different muscle specializations was discussed.

    Plant-Derived Chemicals as Tick Repellents2008Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Ixodes ricinus is the main vector of Lyme borreliosis and Tick-borne encephalitis in Europe. Repellents provide a practical means of protection against tick bites and can therefore reduce transmission of tick-borne diseases.

    In laboratory tests, pieces of cloth treated with MyggA Natural® (a commercial insect repellent) or with the essential oils of Corymbia citriodora (30%), Lavandula angustifolia (1 and 30%), Pelargonium graveolens (1 and 30%), Hyptis suaveolens (10%), Salvadora persica, Pistacia atlantica, Juniperus phoenicea (20%) and methyl jasmonate (MJ) (0.5%, 1.0%, 2.0% and 5.0%) showed strong repellent activity against I. ricinus nymphs.

    In a tick-infested woodland in east-central Sweden, we tested by randomized, standardised methodology the potential anti-tick repellent activity of MyggA Natural® (roll-on), two concentrations of MyggA Natural® spray, RB86 (a commercially available insect repellent for horses), the essential oil of C. citriodora and three concentrations of MJ. Each substance was dissolved in acetone and applied separately to 1 m2 cloths which were then pulled over vegetation. Nymphal tick numbers on the cloths were recorded at 10-m intervals and differed significantly between treated cloths and the untreated control and also between collectors.

    Volatile compounds from fresh and dried leaves of H. suaveolens and the essential oils of H. suaveolens (from Laos and Guinea Bissau) and S. persica, P. atlantica and J. phoenicea (from Libya) were collected by solid phase micro-extraction (SPME) and the constituents were identified by gas chromatography - mass spectrometry (GC-MS). Two main sesquiterpene hydrocarbons in the H. suaveolens oil were β-caryophyllene and humulene. These were modified by oxidation and sulphidation to obtain effective tick repellent compounds with lower volatility. In all three oils from Libyan plants the main monoterpene hydrocarbons were α-pinene, sabinene, β-pinene, myrcene, α-phellandrene, 4-carene, β-phellandrene and γ-terpinene.

    The selected plant species contained numerous volatiles known to have insecticidal, acaricidal, and/or insect repellent properties.

    Abstract [en]

    In the field in south-central Sweden, we tested by randomised, standardised methodology the potential anti-tick repellent activity of two concentrations of MyggA® Natural spray (containing PMD) (4.2 and 3.2 g/m2) and one of RB86 (with 70% neem oil containing azadirachtin)(3 g/m2) to host seeking nymphs of Ixodes ricinus. Each substance was applied separately to 1 m2 cotton flannel cloths. Nymphal ticks on the cloths, pulled over the vegetation, were recorded at 10-m stops. Nymphal numbers recorded differed significantly between treated cloths [4.2 or 3.2 g MyggA® Natural spray/m2 and 3 g RB86/m2] and the untreated control (df = 3, χ2 = 112.74, P < 0.0001). Nymphal numbers also differed significantly among collectors (df = 3, χ2 = 15.80, P < 0.001). Repellency of treated cloths, i.e., 4.2 or 3.2 g MyggA® Natural spray/m2 and 3 g RB 86/m2 declined from day 0 (i.e. the day of impregnation) to day 3 after impregnation from 77 to 24%, 58 to 16% and 47 to 0.5%, respectively. This study suggests that all three treatments have significant repellent activities against I. ricinus nymphs.

    Abstract [en]

    In our search for tick repellents of plant origin, to be used as alternatives to commercial arthropod repellents, we investigated the effect of the well known plant signaling compound methyl jasmonate (MJ) using nymphs of the tick Ixodes ricinus. In laboratory tests, pieces of cloth with MJ at 0.075, 0.15, 0.30 and 0.75 mg/cm2 yielded increasing repellencies against the nymphs: 57%, 71%, 92% and 99%, respectively, of the nymphs did not cling to the cloth. Repellency of MJ was also investigated in a tick-infested woodland area in central Sweden. Cotton flannel cloths sprayed with 0.05, 0.1 or 0.2 mg/cm2 MJ dissolved in acetone were dragged over the ground vegetation. The numbers of nymphs on the treated cloths were significantly lower than those on the untreated cloth. Thus, MJ has, at the concentrations tested, significant repellent activity against I. ricinus nymphs.

    Specimens of Salvadora persica Wallich (Salvadoraceae), Pistacia   atlantica Desfontaines (Anacardiaceae), and Juniperus phoenicea L.   (Cupressaceae) were collected at The Green Mountain in northeastern   Libya. The tick-repellent effects of the essential oils from the plants   were evaluated using host-seeking nymphs of Ixodes ricinus L. (Acari:   Ixodidae) in the laboratory. Significant tick repellent effects were   observed for the oils of all three species, but the duration of action   was short. The oils were obtained by steam distillation. Volatile   compounds of the essential oils were collected by solid phase   microextraction and the constituents were identified by gas   chromatography-mass spectrometry.

    Abstract [en]

    The biology and larval morphology of Ceramida, a pest of olive trees in southern Spain, are described. The life-cycle is multivoltine, spanning three years in the field. Females lay eggs in the early spring, with the highest larval densities in June. Larvae feed on the root system of plants. Pupation takes place in the late summer. Adults emerge with the first autumnal rainfalls, with mating extending from September to January. Larval characters such as type of head pubescence, shape of antennal sensory areas, chaetotaxy of raster, and degree of reduction of metathoracic claws are of taxonomic value within Pachydeminae.

    Integrating processes, time, and patterns: The event-based approach to historical biogeography2005Ingår i: The Systematics Association 5th Biennial Meeting, 2005Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Traditional cladistic biogeographic methods search for concordance between phylogenetic and distribution patterns of different organisms as evidence of a common history of geological isolation events (vicariance). However, these methods are flawed because they only focus on “topological congruence”, overlooking other important sources of information. Biogeographic processes such as dispersal and extinction are not incorporated directly into the analysis, which makes cladistic results very difficult to interpret. Similarly, integration of timing of species divergences is needed if we want to discriminate between alternative biogeographic scenarios, or to exclude “pseudo-congruence”, i.e., congruent patterns that originated at different times. Finally, cladistic methods do not directly attempt to test the statistical significance of results. In this paper, I review recent developments on biogeographic analysis designed to overcome these problems, and illustrate them with case studies. Event-based parsimony methods, such as dispersal-vicariance analysis or parsimony-based tree fitting, are derived from explicit process models and reconstruct both ancestral distributions and biogeographic events. Each process is associated with a cost that should be inversely related to its likelihood, with the most parsimonious explanation of the data being the one of minimum cost. Using large data sets of phylogenies and permutation tests, event-based methods have been used, for example, to study directions of dispersal and test alternative diversification hypotheses in the Holarctic fauna, or to identify patterns of concerted dispersal in the Southern Hemisphere. Other more probabilistic methods include the application of Bayesian Inference to biogeographic analysis, in which dispersal and extinction can be introduced as random parameters in the model. This method is currently under development and would be applied to infer colonization patterns in the Canary Archipelago.

    West Wind Drift revisited: Testing for directional dispersal in the Southern Hemisphere using event-based tree fitting2007Ingår i: Journal of Biogeography, ISSN 0305-0270, E-ISSN 1365-2699, Vol. 34, nr 3, s. 398-416Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim Recent studies suggest that if constrained by prevailing wind or ocean currents dispersal may produce predictable, repeated distribution patterns. Dispersal mediated by the West Wind Drift (WWD) and Antarctic Circumpolar Current (AAC) has often been invoked to explain the floristic similarities of Australia, South America, and New Zealand. If these systems have been important dispersal vectors then eastward dispersal – from Australia to New Zealand and the western Pacific to South America – is expected to predominate. We investigate whether phylogenies for Southern Hemisphere plant groups provide evidence of historical dispersal asymmetry and more specifically whether inferred asymmetries are consistent with the direction of the WWD/AAC.

    Location Southern Hemisphere.

    Methods We assembled a data set of 23 published phylogenies for plant groups that occur in New Zealand, Australia, and/or South America. We used parsimony-based tree fitting to infer the number and direction of dispersals within each group. Observed dispersal asymmetries were tested for significance against a distribution of expected values.

    Results Our analyses suggest that dispersal has played a major role in establishing contemporary distributions and that there are significant patterns of asymmetry in Southern Hemisphere dispersal. Consistent with the eastward direction of the WWD/ACC dispersal from Australia to New Zealand was inferred significantly more often than in the reverse direction. No significant patterns of dispersal asymmetry were found between the western Pacific landmasses and South America. However, eastward dispersal was more frequently inferred between Australia and South America, while for New Zealand-South American events westward dispersal was more common.

    Main conclusions Our results suggest that eastward circumpolar currents have constrained dispersal of plants between Australia and New Zealand. However, the WWD/ACC appear to have had less of an influence on dispersal between the western Pacific landmasses and South America. This observation may suggest that differences in dispersal mechanism are important – direct wind or water dispersal versus stepping-stone dispersal along the Antarctic coast. While our analyses provide useful preliminary insights into dispersal asymmetry in the Southern Hemisphere we will need larger data sets and additional methodological advances in order to fully test these dispersal patterns and infer processes from phylogenetic data.

    Heterotachy processes in rhodophyte-derived secondhand plastid genes: Implications for addressing the origin and evolution of dinoflagellate plastids2006Ingår i: Molecular biology and evolution, ISSN 0737-4038, E-ISSN 1537-1719, Vol. 23, nr 8, s. 1504-1515Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Serial transfer of plastids from one eukaryotic host to another is the key process involved in evolution of secondhand plastids. Such transfers drastically change the environment of the plastids and hence the selection regimes, presumably leading to changes over time in the characteristics of plastid gene evolution and to misleading phylogenetic inferences. About half of the dinoflagellate protists species are photosynthetic and unique in harboring a diversity of plastids acquired from a wide range of eukaryotic algae. They are therefore ideal for studying evolutionary processes of plastids gained through secondary and tertiary endosymbioses. In the light of these processes, we have evaluated the origin of 2 types of dinoflagellate plastids, containing the peridinin or 19'-hexanoyloxyfucoxanthin (19'-HNOF) pigments, by inferring the phylogeny using "covarion" evolutionary models allowing the pattern of among-site rate variation to change over time. Our investigations of genes from secondary and tertiary plastids derived from the rhodophyte plastid lineage clearly reveal "heterotachy" processes characterized as stationary covarion substitution patterns and changes in proportion of variable sites across sequences. Failure to accommodate covarion-like substitution patterns can have strong effects on the plastid tree topology. Importantly, multigene analyses performed with probabilistic methods using among-site rate and covarion models of evolution conflict with proposed single origin of the peridinin- and 19'-HNOF-containin- plastids, suggesting that analysis of secondhand plastids can be hampered by convergence in the evolutionary signature of the plastid DNA sequences. Another type of sequence convergence was detected at protein level involving the psaA gene. Excluding the psaA sequence from a concatenated protein alignment grouped the peridinin plastid with haptophytes, congruent with all DNA trees. Altogether, taking account of complex processes involved in the evolution of dinoflagellate plastid sequences (both at the DNA and amino acid level), we demonstrate the difficulty of excluding independent, tertiary origin for both the peridinin and 19'-HNOF plastids involving engulfment of haptophyte-like algae. In addition, the refined topologies suggest the red algal order, Porphyridales, as the endosymbiont ancestor of the secondary plastids in cryptophytes, haptophytes, and heterokonts.
