    Effects of environment on compensatory mutations to ameliorate costs of antibiotic resistance2000In: Science, ISSN 0036-8075, E-ISSN 1095-9203, Vol. 287, no 5457, p. 1479-1482Article in journal (Refereed)
    Abstract [en]

    Most types of antibiotic resistance impose a biological cost on bacterial fitness. These costs can be compensated, usually without loss of resistance, by second-site mutations during the evolution of the resistant bacteria in an experimental host or in a laboratory medium. Different fitness-compensating mutations were selected depending on whether the bacteria evolved through serial passage in mice or in a laboratory medium. This difference in mutation spectra was caused by either a growth condition-specific formation or selection of the compensated mutants. These results suggest that bacterial evolution to reduce the costs of antibiotic resistance can take different trajectories within and outside a host.

    Molecular phylogenetics and taxonomy of leaf-toed geckos (Phyllodactylidae: Phyllodactylus) inhabiting the peninsula of Baja California2009In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, no 2027, p. 28-42Article in journal (Refereed)
    Abstract [en]

    Herein we assess the phylogenetic relationships and taxonomy of geckos of the genus Phyllodactylus inhabiting the peninsula of Baja California, Mexico using five mitochondrial and two nuclear genes. Phylogenetic analysis using maximum parsimony (MP) and Bayesian inference (BI) recovered three distinct peninsular clades with high statistical support. Sequence divergence estimates between peninsular taxa approached 13%. Two of the species, P. unctus and P. xanti are Cape Region endemics, whereas P. nocticolus is widespread throughout much of the peninsula and extreme southern California. Monophyly of the peninsular taxa was strongly supported. In the MP analysis, P. unctus rooted at the base of the peninsular clade, resolving P. xanti and P. nocticolus as sister taxa. Conversely, BI placed P. nocticolus and P. unctus as sister taxa. These data provide further evidence for a trans-peninsular seaway near the Isthmus of La Paz, severing the Cape Region from the rest of the peninsula. The analysis also supports the validity of P. nocticolus as a distinct species and suggests a single invasion to the peninsula from mainland Mexico, presumably during tectonic activity during the Miocene.

    Climate Related Impacts on a Lake : From Physics to Biology2001Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Climatic variation and change affect the dynamics of organisms and ecosystem processes. This thesis examines phytoplankton as a target variable to trace climatic impacts on Lake Erken (Sweden) with special emphasis on the spring bloom.

    A strong correlation between the timing of the spring bloom and the North Atlantic Oscillation (NAO) illustrates the link between atmospheric pressure variations and local biological processes. The predictive power increased by applying a recently established regional Scandinavian Circulation Index (SCI). Changes to an earlier timing of the spring bloom and elevated water temperature were induced by the global warming trend. The climate signal was still persistent in summer manifested by an enhanced summer phytoplankton biomass.

    Between spring and summer, the phytoplankton was mainly controlled by phosphorus limitation. The application of a new method to measure alkaline phosphatase activity revealed that P-limitation varied between species and among individual cells.

    Combining the above knowledge and literature data, the impact of the NAO on the timing of life history events, biomass and trophic cascade in aquatic and terrestrial ecosystems was quantitatively tested with a meta-analysis. In all environments, pronounced effects of the NAO were apparent, indicating the generality of climate effects found in different ecosystems.

    Finally, a regional climate model was applied, forcing a physical lake model from which future lake conditions were simulated. The simulation revealed a one-month shorter ice cover period with two years out of ten being completely ice free. Internal eutrophication is one of the expected consequences.

    In conclusion, the strong influences of global and regional climate are apparent in local physical, chemical and biological variables and will most probably also in future affect the structure and function of processes in lakes.

    Effects of mineral and nutrient input on mire bio-geochemistry in two geographical regions2003In: Journal of Ecology, ISSN 0022-0477, E-ISSN 1365-2745, Vol. 91, no 3, p. 417-426Article in journal (Refereed)
    Abstract [en]

    1 We assessed the role of climatic conditions and the effects of different, long-term atmospheric depositions in controlling the mineral and nutrient contents in pore-water, surface peat and in living Sphagna at a boreo-nemoral mire in Sweden and an alpine mire in Italy.

    2 The terrestrial contribution of Ca2+, Mg2+ and SO42- in bulk precipitation was much greater at the Italian mire, in accordance with the different bedrock in the region and the higher level of atmospheric pollution.

    3 At both mires, the contribution of bulk precipitation to the concentration of major ions in mire pore-water was much greater in the ombrotrophic than in the minerotrophic part, because of the raised morphology of the mires, which limited the inflow of mineral soil water to the margins. The only ions strongly depleted in mire pore-water compared with precipitation were K+, NO3- and NH4+ and these were therefore limiting to plant growth.

    4 Higher SO42- concentration in pore-water at the Swedish mire, which experienced lower atmospheric inputs of sulphate, was probably caused by oxidative processes during a long dry period in the summer before sampling.

    5 Higher rates of NO3-, NH4+, as well as SO42- atmospheric inputs at the Italian mire were reflected in significantly higher N and, partly, S concentrations in ombrotrophic Sphagna. Higher NO3- concentration in pore-water at the Italian mire was associated with a lower N retention coefficient of the ombrotrophic Sphagnum plants, suggesting a reduced nitrogen filtering ability of the moss layer.

    Abstract [en]

    Using different data sets mainly from the plant family Rubiaceae, but in parts also from the Apocynaceae, Asteraceae, Lardizabalaceae, Saxifragaceae, and Solanaceae, we have investigated the effect of number of characters, number of taxa, and kind of
