Abstract [en]

Patterns of species diversity and community structure depend on scales larger than just a single habitat and might be influenced by the surrounding landscape. We studied the response of two insect families, mosquitoes (Diptera: Culicidae) and dytiscids (Coleoptera: Dytiscidae), to landscape variables at five spatial scales. We studied adult mosquito and dytiscid abundance, diversity, and species assemblages in relation to water permanence (area of permanent water bodies versus temporary wetlands) and forest cover (area covered by forest versus open land) within nested circles of 100 to 3000 m around trap sites in four wetlands in southern Sweden and in five wetlands in central Sweden. We found that mosquito abundance was greatest in areas with plentiful forest cover and a high proportion of temporary water, while most dytiscids favored open areas with a high proportion of permanent wetlands. However, diversity of both mosquitoes and dytiscids was positively correlated with high permanence and little forest cover. Mosquito species assemblages were mainly influenced by forest cover at a large spatial scale, whereas permanence was more important at local scales. Dytiscid species assemblages were mainly influenced by water permanence, especially at intermediate spatial scales. These results can be explained by the flight capability and dispersal behavior of mosquito and dytiscid species. The observed landscape associations of mosquitoes and dytiscids could be useful when creating new wetlands. Mosquito colonization could be reduced by creating permanent wetlands in an open landscape, which would favor colonization by dytiscids, a potential predator of mosquito larvae, while also supporting the diversity of both taxa.

Abstract [en]

Wetlands contain both aquatic and terrestrial environments which generates high biodiversity. However, they are commonly associated with mosquitoes (Diptera: Culicidae), and mosquitoes are usually regarded as negative by humans because they can cause nuisance and transmit diseases. This thesis aimed to clarify the association between mosquitoes and wetlands and to achieve a more balanced view of biodiversity in wetlands by including mosquito diversity.

Studies on adult mosquito diversity and assemblages were performed in 18 wetlands spread over Sweden. The Swedish mosquito species were organized in ten functional groups based on four life-history characteristics. This classification was used as an additional diversity measurement and as a tool for presentation of mosquito data.

Mosquito diversity showed several of the well-established diversity patterns such as a latitudinal gradient, a species-area relationship and a distribution-abundance relationship. In a landscape perspective, diversity of both mosquitoes and dytiscids (Coleoptera: Dytiscidae) were positively influenced by a high proportion of permanent water and a high amount of open areas, indicating co-varying diversity patterns.

Mosquito assemblages in the Nedre Dalälven region were mainly structured by the extent of flooded areas and wetland type (wet meadow, swamp and bog). In addition to the influence of the proportion of temporary wetlands at a local scale, the proportion of forest gained importance at larger spatial scales and in relation to dispersal distances of species. In southern Sweden, mosquito faunas differed between natural and constructed wetlands, partly reflecting differences in wetland size. In an experiment, different responses of two co-occurring mosquito species to rapid larval habitat desiccation indicate that weather conditions after a flood could influence mosquito assemblages.

The conclusions of this thesis provide suggestions on how to construct and position wetlands for increased insect diversity, and indicate that low abundance of major nuisance species might be crucial for acceptance of wetlands near human settlements.
