Data from: Temperature-driven colour lightness and body size variation scale to local assemblages of European Odonata but are modified by propensity for dispersalDaniel Acquah-Lamptey, Martin Braendle, Roland Brandl & Stefan Pinkert
Previous macrophysiological studies suggested that temperature-driven colour lightness and body size variations strongly influence biogeographical patterns in ectotherms. However, these trait-environment relationships scale to local assemblages and the extent to which they can be modified by dispersal remains largely unexplored. We test whether the predictions of the thermal melanism hypothesis and the Bergmann’s rule hold for local assemblages. We also assess whether these trait-environment relationships are more important for species adapted to less stable (lentic)...
Climate-diversity relationships underlying cross-taxon diversity of the Africa fauna and their implications for conservationStefan Pinkert, Dirk Zeuss, Viola Clausnitzer, Jens Kipping, Klaas-Douwe B. Dijkstra, Stefan Brunzel & Roland Brandl
Aim: Many taxa show remarkable similarities in their diversity patterns and these similarities are commonly used to define large-scale conservation priorities. Here, we investigated the relative importance of contemporary climate and climate change since the Last Glacial Maximum for determining the species richness and rarity patterns of four animal taxa. We assessed the extent to which diversity patterns are congruent across taxa because of similar responses to these climatic aspects and we identify regions that...
Comparison of native and non-native predator consumption rates and prey avoidance behavior in North America and EuropeAyse Gül Ünlü, John J. Obrycki & Roman Bucher
Novel predator-prey interactions can contribute to the invasion success of non-native predators. For example, native prey can fail to recognize and avoid non-native predators due to a lack of co-evolutionary history and cue dissimilarity with native predators. This might result in a competitive advantage for non-native predators. Numerous lady beetle species were globally redistributed as biological control agents against aphids, resulting in novel predator-prey interactions. Here, we investigated the strength of avoidance behavior of the...
At the present time there are problems with water supplies to the city of Astana. The problems are related to the quality of water in the Ishim River. In the future, after commissioning of the Satpayev Canal, this problem will become more serious due to the Irtysh River pollution. Because of it, considering the currently observed hydro-chemical regime of the Ishim and Irtysh rivers pollution, the following preventive measures to be taken in advance to...
Timing of activity can reveal an organism’s efforts to optimize foraging either by minimizing energy loss through passive movement or by maximizing energetic gain through foraging. Here, we assess whether signals of either of these strategies are detectable in the timing of activity of daily, local movements by birds. We compare the similarities of timing of movement activity among species using six temporal variables: start of activity relative to sunrise, end of activity relative to...
Relative effects of climate and litter traits on decomposition change with time, climate and trait variabilityRafaella Canessa, Liesbeth Van Den Brink, Alfredo Saldana, Rodrigo Rios, Stephan Hattenschwiler, Carsten Mueller, Isabel Prater, Katja Tielboerger & Maaike Bader
Climate and litter quality drive litter decomposition, but there is currently little consensus on their relative importance, likely because studies differ in the duration, the climatic gradients, and variability in litter-trait values. Understanding these drivers is important because they determine the direct and indirect (via vegetation composition) effects of climate change on decomposition and thereby on carbon and nutrient cycling. We studied how microclimate (soil moisture and temperature) and litter traits interactively affect litter mass...
Mobility costs and energy uptake mediate the effects of morphological traits on species’ distribution and abundanceStefan Pinkert, Nicolas Friess, Dirk Zeuss, Martin Gossner, Roland Brandl & Stefan Brunzel
Individuals of large or dark-colored ectothermic species often have a higher reproduction and activity than small or light-colored ones. However, investments into body size or darker colors should negatively affect the fitness of individuals as they increase their growth and maintenance costs. Thus, it is unlikely that morphological traits directly affect species’ distribution and abundance. Yet, this simplification is frequently made in trait-based ecological analyses. Here, we integrated the energy allocation strategies of species into...
