Data from: Genetic differentiation of western capercaillie in the Carpathian Mountains reveal the importance of post glacial expansions and habitat connectivity in understanding the present day European distribution

Peter Klinga, Martin Mikoláš, Petar Zhelev, Jacob Höglund & Ladislav Paule
Population structure and barriers to gene flow are important components for understanding the evolutionary history of a species. Here we study population structure and differentiation in the western capercaillie (Aves: Phasianidae) along the Carpathian Mountains. Further, we compared the levels of population differentiation among capercaillie from the Carpathian Mountains, Balkans (Bulgaria) and the boreal forest (Russia and Sweden) in order to reveal past and current processes which may influence population structure. Tissue samples, non-invasive faeces...

Data from: A new perspective on Melanophloea, Thelocarpella and Trimmatothelopsis: species previously placed in multiple families are united within a single genus in the Acarosporaceae

Kerry Knudsen & James C. Lendemer
Recent molecular phylogenetic studies of the lichen family Acarosporaceae have shown that genera in this group, as traditionally defined, are not monophyletic and that changes are required to accommodate the discovery that taxa with disparate thallus morphologies are often closely related. Here we use phylogenetic inferences of mtSSU sequence data to show that seven species (Acarospora dispersa, A. rhizobola, A. terricola, Melanophloea americana, M. coreana, M. montana and Thelocarpella gordensis), currently placed in four genera...

Colony-age-dependent variation in cuticular hydrocarbon profiles in subterranean termite colonies

Johnalyn Gordon, Jan Šobotník & Thomas Chouvenc
Cuticular hydrocarbons (CHCs) have, in insects, important physiological and ecological functions, such as protection against desiccation and as semiochemicals in eusocial taxa, including termites. CHCs are, in termites, known to vary qualitatively and/or quantitatively among species, populations, or seasons. Changes to hydrocarbon profile composition have been linked to varying degrees of aggression between termite colonies, although the variability of results among studies suggests that additional factors might have been involved. One source of variability may...

Juggling options: manipulation ease determines primate optimal fruit size choice

Renann H. P. Dias-Silva, Matheus J. Castro Sa, Fabricio B. Baccaro, Pavel Tománek & Adrian A. Barnett
Optimal foraging theory predicts that animals will seek simultaneously to minimize food processing time and maximize energetic gain. To test this hypothesis, we evaluated whether a specialist seed-predator primate forages optimally when choosing among variable-sized thick-husked fruits. Our objects of study were the golden-backed-uacari (Cacajao ouakary, Pitheciidae) and single seeded pods of the macucu tree (Aldina latifolia, Fabaceae). We predicted that golden-backed-uacari will consume fruits of the size class that requires the least time to...

Forest cover and proximity decrease herbivory and increase crop yield via enhanced natural enemies in soybean fields

Ezequiel Gonzalez, Doug Landis, Michal Knapp & Graciela Valladares
Non-crop habitats are essential for sustaining biodiversity of beneficial arthropods in agricultural landscapes, which can increase ecosystem services provision and crop yield. However, their effects on specific crop systems are less clear, such as soybean in South America, where the responses of pests and natural enemies to landscape structure have only recently been studied. Here, we analyzed how native forest fragments at local and landscape scales influenced arthropod communities, herbivory, and yield in soybean fields...

Data from: Along with intraspecific functional trait variation, individual performance is key to resolving community assembly processes

Jana Doudová & Jan Douda
Species contributing high proportions to community biomass strongly influence ecosystem processes within the community. Studies have shown that dominant species may serve as nurse plants, helping to ensure biomass stability of the subordinate species under stress conditions. The question is widely debated as to whether either niche differentiation or neutral processes drive the net outcome of plant interactions within a subordinate plant community. To answer this question, requires precise estimates of individual variation in functional...

Data from: Direct and indirect effects of landscape and field management intensity on carabids through trophic resources and weeds

Benjamin Carbonne, David A. Bohan, Hana Foffovà, Eirini Daouti, Britta Frei, Veronika Neidel, Pavel Saska, Jiří Skuhrovec & Sandrine Petit
Carabids are important biological control agents of weeds and other pests in agricultural fields. The carabid community is built upon direct and indirect ecological effects of landscape complexity, field management intensity and biotic components that in interaction make any prediction of community size and composition challenging. We analyse a large-scale sample of 60 European cereal fields using Structural Equation Modelling to quantify the direct effects of field management intensity and the surrounding landscape, and their...
