Data from: Chironomus riparius (Diptera) genome sequencing reveals the impact of minisatellite transposable elements on population divergenceAnn-Marie Oppold, Hanno Schmidt, Marcel Rose, Sören Lukas Hellman, Florian Dolze, Fabian Ripp, Bettina Weich, Urs Schmidt-Ott, Erwin Schmidt, Robert Kofler, Thomas Hankeln & Markus Pfenninger
Active transposable elements (TEs) may result in divergent genomic insertion and abundance patterns among conspecific populations. Upon secondary contact, such divergent genetic backgrounds can theoretically give rise to classical Dobzhansky-Muller incompatibilities (DMI), thus contributing to the evolution of endogenous genetic barriers and eventually cause population divergence. We investigated differential TE abundance among conspecific populations of the non-biting midge Chironomus riparius and evaluated their potential role in causing endogenous genetic incompatibilities between these populations. We focussed...
Data from: Seed-dispersal networks respond differently to resource effects in open and forest habitatsMaximilian G. R. Vollstaedt, Stefan W. Ferger, Andreas Hemp, Kim M. Howell, Katrin Böhning-Gaese & Matthias Schleuning
While patterns in species diversity have been well studied across large-scale environmental gradients, little is known about how species' interaction networks change in response to abiotic and biotic factors across such gradients. Here we studied seed-dispersal networks on 50 study plots distributed over ten different habitat types on the southern slopes of Mt. Kilimanjaro, Tanzania, to disentangle the effects of climate, habitat structure, fruit diversity and fruit availability on different measures of interaction diversity. We...
Data from: Biotic interactions and seed deposition rather than abiotic factors determine recruitment at elevational range limits of an alpine treeEike Lena Neuschulz, Dominik Merges, Kurt Bollmann, Felix Gugerli & Katrin Böhning-Gaese
1. Abiotic factors, biotic interactions and dispersal ability determine the spatial distribution of species. Theory predicts that abiotic constraints set range limits under harsh climatic conditions and biotic interactions set range limits under benign climatic conditions, whereas dispersal ability should limit both ends of the distribution. However, empirical studies exploring how these three components jointly affect species across environmental gradients are scarce. 2. Here we present a study that jointly examines these factors to investigate...
Data from: Adaptive differentiation coincides with local bioclimatic conditions along an elevational cline in populations of a lichen-forming fungusFrancesco Dal Grande, Rahul Sharma, Anjuli Meiser, Gregor Rolshausen, Burkhard Buedel, Bagdevi Mishra, Marco Thines, Juergen Otte, Markus Pfenninger & Imke Schmitt
Background: Many fungal species occur across a variety of habitats. Particularly lichens, fungi forming symbioses with photosynthetic partners, have evolved remarkable tolerances for environmental extremes. Despite their ecological importance and ubiquity, little is known about the genetic basis of adaption in lichen populations. Here we studied patterns of genome-wide differentiation in the lichen-forming fungus Lasallia pustulata along an altitudinal gradient in the Mediterranean region. We resequenced six populations as pools and identified highly differentiated genomic...
Data from: Evolutionary processes, dispersal limitation and climatic history shape current diversity patterns of European dragonfliesStefan Pinkert, Klaas-Douwe B. Dijkstra, Dirk Zeuss, Christoph Reudenbach, Roland Brandl & Christian Hof
We investigated the effects of contemporary and historical factors on the spatial variation of European dragonfly diversity. Specifically, we tested to what extent patterns of endemism and phylogenetic diversity of European dragonfly assemblages are structured by (i) phylogenetic conservatism of thermal adaptations and (ii) differences in the ability of post-glacial recolonization by species adapted to running waters (lotic) and still waters (lentic). We investigated patterns of dragonfly diversity using digital distribution maps and a phylogeny...
Data from: Quantifying the climatic niche of symbiont partners in a lichen symbiosis indicates mutualist-mediated niche expansionsGregor Rolshausen, Francesco Dal Grande, Anna Sadowska-Deś, Juergen Otte & Imke Schmitt
The large distributional areas and ecological niches of many lichenized fungi may in part be due to the plasticity in interactions between the fungus (mycobiont) and its algal or cyanobacterial partners (photobionts). On the one hand, broad-scale phylogenetic analyses show that partner compatibility in lichens is rather constrained and shaped by reciprocal selection pressures and codiversification independent of ecological drivers. On the other hand, sub-species-level associations among lichen symbionts appear to be environmentally structured rather...
Data from: Cross-taxa generalities in the relationship between population abundance and ambient temperaturesDiana E. Bowler, Peter Haase, Christian Hof, Ingrid Kröncke, Léon Baert, Wouter Dekoninck, Sami Domisch, Frederik Hendrickx, Thomas Hickler, Hermann Neumann, Robert B. O'Hara, Anne F. Sell, Moritz Sonnewald, Stefan Stoll, Michael Türkay, Roel Van Klink, Oliver Schweiger, Rikjan Vermeulen & Katrin Boehning-Gaese
Identifying patterns in the effects of temperature on species' population abundances could help develop a general framework for predicting the consequences of climate change across different communities and realms. We used long-term population time series data from terrestrial, freshwater, and marine species communities within central Europe to compare the effects of temperature on abundance across a broad range of taxonomic groups. We asked whether there was an average relationship between temperatures in different seasons and...
1. Organisms from temperate zones are exposed to seasonal changes and must be able to cope with a wide range of climatic conditions. Especially ectotherms, including insects, are at risk to desiccate under dry and warm conditions, the more so given the changing climate. 2. To adjust to current conditions, organisms acclimate through changes in physiology, morphology and/or behaviour. Insects protect themselves against desiccation through a layer of cuticular hydrocarbons (CHC) on their body surface....
