Environmental and behavioral factors affect northern bobwhite offspring survival

Acute toxicity of diphacinone in Northern bobwhite: effects on survival and blood clotting.

The anticoagulant rodenticide diphacinone was slightly toxic (acute oral LD50 2014 mg/kg) to Northern bobwhite (Colinus virginianus) in a 14-day acute toxicity trial. Precise and sensitive assays of blood clotting (prothrombin time, Russell's Viper venom time, and thrombin clotting time) were adapted for use in quail, and this combination of assays is recommended to measure the effects of antic...

ENVIRONMENTAL FACTORS AFFECT THE SURVIVAL AND EXPRESSION OF VIRULENT CYTOLETHAL DISTENDING TOXIN OF Campylobacter jejuni

Several environmental factors regulate the expression of virulence genes under certain conditions and the expression of bacterial virulence determinants. Cytolethal distending toxin (CDT) is an important virulence determinant secreted by Campylobacter jejuni (C. jejuni), a leading cause of gastrointestinal bacterial pathogen worldwide. Therefore, the aim of the study was to investigate the effe...

Impacts of predation on northern bobwhite and scaled quail

Environmental factors that affect the survival and persistence of Burkholderia pseudomallei.

Sampling of Bobwhite Populations Estimating Sample Sizes for Distance Sampling of Autumn Northern Bobwhite Calling Coveys

Point transect sampling of calling coveys has been advocated for estimating autumn abundance of northern bobwhite (Colinus virginianus; hereafter bobwhite). We conducted power analysis, over a range of expected bobwhite calling covey densities to determine levels of sampling required to obtain density estimates for calling coveys over a wide range of precision. We used distance/detection inform...
