Contrasting genetic responses to habitat fragmentation for two Lycaenid butterfly species

Daronja Trense, Jan Christian Habel, Aline Finger & Klaus Fischer
Biodiversity is currently declining at the global scale. Apart from species declines and lowered abundances, the loss of genetic diversity is equally concerning as it may undermine fitness and the potential to adapt to future environmental change. We compared genetic diversity of historical and recent Alpine populations of two butterfly species, Lycaena helle and L. hippothoe, over a period of about 10 years. Using microsatellite markers, we found no changes over time in L. helle,...

Data from: Leaf litter breakdown along an elevational gradient in Australian alpine streams

Lloyd Werry, Mirco Bundschuh, Simon Mitrovic, Richard Lim & Ben Kefford
These data were generated to investigate the rate of leaf litter breakdown and how temperature and other factors such as microbial and and invertebrate activities were influenced over elevational and temporal gradients. Breakdown of allochthonous organic matter is a central step in nutrient cycling in stream ecosystems. There is concern that increased temperatures from climate change will alter the breakdown rate of organic matter with important consequences for ecosystem functioning of alpine streams. Dried leaves...

Data for: Simulating effects of agricultural intensification and climate change: Nitrogen fertilization and drought stress decrease insect herbivore performance

Ange Raharivololoniaina, Ellen Moewert & Klaus Fischer
Biodiversity is globally under pressure, and the current decline in insect biomass and diversity is likely caused by human activities. Key drivers of biodiversity loss include agricultural intensification and anthropogenic climate change. Nevertheless, a thorough understanding of potential interactions between both factors and the mechanisms underlying insect declines in general is still lacking. Here, we investigate the combined effects of nitrogen fertilization and drought, as applied to host plants, on the preference and performance of...

Data from: Metabarcoding of trap nests reveals differential impact of urbanization on cavity-nesting bee and wasp communities

Ellen Dürrbaum, Felix Fornoff, Christoph Scherber, Eero Vesterinen & Bernhard Eitzinger
Urbanization is affecting arthropod communities worldwide, for example by changing the availability of food resources. However, the strength and direction of a community’s response are species-specific and depend on the species’ trophic level. Here, we investigated interacting species at different trophic levels in nests of cavity-nesting bees and wasps along two urbanization gradients in four German cities using trap nests. We analyzed bee and wasp diversity and their trophic interaction partners by metabarcoding the DNA...

Contrasting effects of vineyard type, soil and landscape factors on ground- versus above-ground nesting bees

Vera Wersebeckmann, Daniela Warzecha, Martin H. Entling & Leyer Ilona
1. Agricultural intensification and abandonment of traditional agricultural practices are main drivers of current insect declines. The resulting loss of feeding and nesting opportunities has led to a decrease in pollinator populations like wild bees. While the restoration of floral resources has been widely implemented in wild bee conservation, nesting resources, particularly for ground-nesting species, are barely considered. 2. We assessed wild bee diversity in a wine-growing area in Germany in 15 study sites along...

Molecular tracking and prevalence of the red colour morph restricted to a harvested leopard population in South Africa

Laura Tensen
The red leopard (Panthera pardus) colour morph is a colour variant that occurs only in South Africa, where it is confined to the Central Bushveld bioregion. Red leopards have been spreading over the past 40 years, which raises the speculation that the prevalence of this phenotype is related to low dispersal of young individuals owing to high off-take in the region. Intensive selective hunting tends to remove large resident males from the breeding population, which...

Data for: The central Alps comprise a major dispersal barrier between western and eastern populations of two butterfly species

Daronja Trense, Laura Jager & Klaus Fischer
Aim: Environmental and species-specific factors shape spatial patterns in genetic diversity and population structure. Comparing different species within the same area helps to disentangle more general from species-specific factors affecting such geographic patterns. Here, we examined genetic diversity and population structuring through geographic features in two alpine butterfly species. Location: European Alps. Taxon: Copper butterflies (Lycaena spp.). Methods: We sampled 21 Lycaena hippothoe and 14 L. virgaureae populations with 18 individuals per population. We analysed...
