Data from: Dietary antioxidants attenuate the endocrine stress response during long-duration flight of a migratory birdStefania Casagrande, Kristen Demoranville, Lisa Trost, Barbara Pierce, Amadeusz Bryla, Maciej Dzialo, Edyta Sadowska, Ulf Bauchinger & Scott McWilliams
Glucocorticoids (GCs) are metabolic hormones that promote catabolic processes, which release stored energy and support high metabolic demands such as during prolonged flights of migrating birds. Dietary antioxidants (e.g., anthocyanins) support metabolism by quenching excess reactive oxygen species produced during aerobic metabolism, and also by activating metabolic pathways that, similar to GCs’ function, release stored energy, although the extent of complementarity between GCs and dietary antioxidants is not well known. If anthocyanins complement GCs functions,...
Earth’s biodiversity is undergoing mass extinction due to anthropogenic compounding of environmental, demographic and genetic stresses. These different stresses can trap populations within a reinforcing feedback loop known as the extinction vortex, in which synergistic pressures build upon one another through time, driving down population viability. Sexual selection, the widespread evolutionary force arising from competition, choice and reproductive variance within animal mating patterns, could have vital consequences for population viability and the extinction vortex: 1)...
Trait-based analyses explaining the different responses of species and communities to environmental changes are increasing in frequency. European butterflies are an indicator group that responds rapidly to environmental changes with extensive citizen science contributions to documenting changes of abundance and distribution. Species traits have been used to explain long- and short-term responses to climate, land-use and vegetation changes. Studies are often characterised by limited traits sets being used, with risks that the relative roles of...
Data from: A critical analysis of the potential for EU Common Agricultural Policy measures to support wild pollinators on farmlandLorna Cole, David Kleijn, Lynn Dicks, Jane Stout, Simon Potts, Matthias Albrecht, Mario Balzan, Ignasi Bartomeus, Penelope Bebeli, Danilo Bevk, Jacobus Biesmeijer, Róbert Chlebo, Anželika Dautartė, Nikolaos Emmanouil, Chris Hartfield, John Holland, Andrea Holzschuh, Nieke Knoben, Anikó Kovács-Hostyánszki, Yael Mandelik, Heleni Panou, Robert Paxton, Theodora Petanidou, Miguel Pinheiro De Carvalho, … & Jeroen Scheper
1. Agricultural intensification and associated loss of high-quality habitats are key drivers of insect pollinator declines. With the aim of decreasing the environmental impact of agriculture, the 2014 EU Common Agricultural Policy (CAP) defined a set of habitat and landscape features (Ecological Focus Areas: EFAs) farmers could select from as a requirement to receive basic farm payments. To inform the post-2020 CAP, we performed a European-scale evaluation to determine how different EFA options vary in...
Sexual selection and conflict can act on genes with important metabolic functions, potentially shaping standing genetic variance in such genes, and thus evolutionary potential of populations. Here, using experimental evolution, we show how reproductive competition intensity and thermal environment affect selection on phosphogluconate dehydrogenase (6Pgdh) – a metabolic gene involved in sexual selection and conflict in the bulb mite. The S allele of 6Pgdh increases male success in reproductive competition, but is detrimental to S-bearing...
Biological invasions are a major human induced global change that is threatening global biodiversity by homogenizing the world’s fauna and flora. Species spread because humans have moved species across geographic boundaries and have changed ecological factors that structure ecosystems, such as nitrogen deposition, disturbance, etc. Many biological invasions are caused accidentally, as a byproduct of human travel and commerce driven product shipping. However, humans also have spread many species intentionally because of perceived benefits. Of...
Dispersal is well recognised as a major driver of evolutionary processes in local populations. Nevertheless, dispersal abilities should also be perceived as a life history trait, being subject to evolutionary changes in response to various drivers. Empirical studies investigating these drivers rarely consider that they may influence male and female dispersal differently. The purpose of our study was to document intersexual differences in density-dependent emigration from local habitat patches. As a model system we used...
Research on the behavioral responses of animals to extreme weather events, such as heatwaves, is lacking even though their frequency and intensity in nature are increasing. Here, we investigated the behavioral response to a simulated heatwave in two species of antlions (Neuroptera: Myrmeleontidae). These insects spend the majority of their lives as larvae and live in sandy areas suitable for a trap-building hunting strategy. We used larvae of Myrmeleon bore and Euroleon nostras, which are...
