Understanding global diversity patterns has benefitted from a focus on functional traits and how they relate to variation in environmental conditions among assemblages. Distant communities in similar environments often share characteristics, and for tropical forest mammals, this functional trait convergence has been demonstrated at coarse scales (110-200 km resolution), but less is known about how these patterns manifest at fine scales, where local processes (e.g., habitat features and anthropogenic activities) and biotic interactions occur. Here,...

The expansion wave of an invasive predator leaves declining waterbird populations behind

Marcin Brzeziński, Michał Żmihorski, Marek Nieoczym, Piotr Wilniewczyc & Andrzej Zalewski
Aim: Theory predicts that the evolutionary adaptations of prey to reduce predator pressure often fail in confrontation with non-native predators; thus, their predation usually leads to sharp declines of prey populations. However, over time, prey can develop anti-predator adaptations, reduce predator impact and recover its population. We analyse the numerical response of multiple prey species to the impact of a non-native predator on a large spatiotemporal scale. Location: Poland Methods: Long-term population dynamics of 13...

Data from: Length polymorphisms at two candidate genes explain variation of migratory behaviors in blackpoll warblers (Setophaga striata)

Joel Ralston, Lydia Lorenc, Melissa Montes, William Deluca, Jeremy Kirchman, Brad Woodworth, Stuart Mackenzie, Amy Newman, Hilary A. Cooke, Nikole Freeman, Alex Sutton, Lila Tauzer & D. Ryan Norris
Migratory behaviors such as the timing and duration of migration are genetically inherited and can be under strong natural selection, yet we still know very little about the specific genes or molecular pathways that control these behaviors. Studies in candidate genes Clock and Adcyap1 have revealed that both of these loci can be significantly correlated with migratory behaviors in birds, though observed relationships appear to vary across species. We investigated geographic genetic structure of Clock...

Data from: Competition and specialization in an African forest carnivore community

David Mills, Emmanuel Do Linh San, Hugh Robinson, Sam Isoke, Rob Slotow & Luke Hunter
Globally, human activities have led to the impoverishment of species assemblages and the disruption of ecosystem function. Determining whether this poses a threat to future ecosystem stability necessitates a thorough understanding of mechanisms underpinning community assembly and niche selection. Here, we tested for niche segregation within an African small carnivore community in Kibale National Park, Uganda. We used occupancy modelling based on systematic camera trap surveys and fine-scale habitat measures, to identify opposing preferences between...

Incorporating evaporative water loss into bioenergetic models of hibernation to test for relative influence of host and pathogen traits on white-nose syndrome

Catherine Haase, Nathan Fuller, C. Reed Hranac, David Hayman, Liam McGuire, Kaleigh Norquay, Kirk Silas, Craig Willis, Raina Plowright & Sarah Olson
Hibernation consists of extended durations of torpor interrupted by periodic arousals. The ‘dehydration hypothesis’ proposes that hibernating mammals arouse to replenish water lost through evaporation during torpor. Arousals are energetically expensive, and increased arousal frequency can alter survival throughout hibernation. Yet we lack a means to assess the effect of evaporative water loss (EWL), determined by animal physiology and hibernation microclimate, on torpor bout duration and subsequent survival. White-nose syndrome (WNS), a devastating disease impacting...
