摘要:Recent changes in farming throughout Europe are threatening steppe birds, such as Montagu's Harrier Circus pygargus, a steppe raptor that nests in cereal crops, and is therefore threatened by the destruction of its nests by harvesters. Here we analyse the reproductive biolog...

摘要:The sandhill crane ( Grus canadensis ) congregates in large numbers during its annual spring migrations in Colorado. The Monte Vista National Wildlife Refuge (NWR) in southwestern Colorado celebrates this regular congregation of cranes with an annual spring birdwatching festival ...

摘要:We conducted a statewide study, in June and July 2016, of feral colonies and domesticated hives to understand the current and potential impacts of invasive parasites and pests on honey bee ( Apis mellifera ) populations in Texas. We identify the subspecies for each colony sampled...

摘要:Temporal variation in avian brood parasite condition and reproduction seem to affect host–parasite dynamics. Few studies, however, consider dynamics from the perspective of the parasite. Here we examined how brood parasite body condition and reproductive output vary both sea...

摘要:Large carnivores are key drivers of ecosystem structure and function, yet their populations are declining worldwide. African lion ( Panthera leo ) populations have decreased significantly in recent decades with an estimated 23 000 lions left in Africa. Successful conservatio...

摘要:Maintaining key ecological processes is a strong argument for conserving biodiversity, and this should extend to preventing the local extinction of keystone species that are otherwise common. Seed dispersal is such a process and chacma baboons ( Papio ursinus ursinus ) may facili...

摘要:The Common Raven ( Corvus corax ) is widespread at high latitudes and a noted disperser to remote islands. We hypothesized that, given their dispersal abilities, Alaskan populations would be genetically similar and maintain genetic diversity across thousands of kilometers. W...

摘要:Theory suggests that animals should select resources on the basis of perceived fitness benefits, and avoid other available resources that may result in fitness costs. However, resource selection is both a scale- and a life-stage-specific process, in which the importance of d...

摘要:During migration, birds require stopover habitat to rest and refuel before resuming flight. While long-distance migratory flights represent a large energy investment, stopover accounts for roughly two-thirds of a bird's total energy expenditure during migration. Therefore, birds ...

摘要:Partial migration—a strategy in which some individuals are resident and others are migratory within the same population—is widespread among avian species and could play an important transitional role in the evolution of migratory behavior. Nevertheless, detailed movement dat...
