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: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:To achieve greater understanding of the full annual cycles of birds, it is critical to describe the spatial nature of little-understood phases. One of the least understood aspects of avian annual cycles is the ecology of molt: the periodic replacement of feathers. While work...

摘要:The most recent comprehensive estimates of Northern Spotted Owl ( Strix occidentalis caurina ) natal dispersal distances were reported in 2002. Since then, Northern Spotted Owl populations have experienced substantial demographic changes, with potential attendant changes in ...

摘要:Savanna and woodland are transitional vegetation communities that have largely disappeared while many early-successional bird species have simultaneously declined in abundance. Pine savanna and woodland are being restored in the Midwest through prescribed fire and tree thinn...
