Time scale evolution of avipoxviruses [PDF]

open access: yes, 1952
Avipoxviruses are divided into three clades: canarypox-like viruses, fowlpox-like viruses, and psittacinepox-like viruses. Several molecular clock and demographic models available in the BEAST package were compared on three avipoxvirus genes (P4b ...

Impacts of red imported fire ants Solenopsis invicta on survivorship of hatchlings of the broad-snouted caiman Caiman latirostris [PDF]

open access: yes, 2013
Background: Oviparous vertebrate species are often vulnerable to predation by red imported fire ants (RIFAs, Solenopsis invicta) in natural environments. The necrotic action of the venom can cause localized infections, with subsequent effects on survival

Two centuries of human‐mediated gene flow in northern bobwhites

open access: yesWildlife Society Bulletin, 2017
The northern bobwhite (Colinus virginianus; hereafter, bobwhite) population decline has prompted several studies over the past decade investigating bobwhite population genetics and overall connectivity. The zeitgeist of current quail conservation is that

Acute toxicity of gossypol in northern bobwhites

open access: yesJournal of Applied Animal Research, 2019
Gossypol, a secondary metabolite found in cotton (Gossypium spp.), is known to be toxic to a variety of animals, particularly monogastric mammals and commercial poultry (Gallus domesticus).

An evaluation of population indices for northern bobwhite

open access: yesWildlife Society Bulletin, 2019
Northern bobwhite (Colinus virginianus) populations are monitored using 2 general approaches—population indices and abundance estimators. Due to their convenient sampling designs, indices are commonly used by land managers and researchers to predict or ...

Regional evolutionary distinctiveness and endangerment as a means of prioritizing protection of endangered species [PDF]

open access: yes, 2015
Conservation is costly, and choices must be made about where to best allocate limited resources. I propose a regional evolutionary diversity and endangerment (RED-E) approach to prioritization of endangered species.

Exotic grass alters micro‐climate and mobility for northern bobwhite chicks

open access: yesWildlife Society Bulletin, 2015
Conservation practices are designed to provide habitat conditions that meet the environmental requirements for species of conservation concern. However, exotic invasive grass species may reduce the efficacy of these practices because they disrupt ...

Differences in foraging behavior in wild and pen‐raised northern bobwhites

open access: yesWildlife Society Bulletin, 2016
Increased mortality rates of northern bobwhites (Colinus virginianus) raised in captivity and stocked into the wild compared with wild bobwhites may be due to differences in antipredatory behaviors.

Response of northern bobwhites fed single doses of gossypol

open access: yesWildlife Society Bulletin, 2018
Cottonseed products have been used as a feed supplement for ruminant livestock and white‐tailed deer (Odocoileus virginianus). Gossypol, a secondary plant metabolite found in cotton (Gossypium spp.), is known to be toxic to a variety of animals ...
