Northern bobwhites associated with native grass and shrubs have improved survival

Douglas B. Mitchell, Patrick D. Keyser, David A. Buehler, James A. Martin et autres

Abstract Northern bobwhite ( Colinus virginianus ; bobwhite) populations have dramatically declined across their range. These declines are more pronounced in the southeastern United States, where large proportions of agricultural land have been converted to pasture dominated by tall fescue ( Lolium …

Joint telemetry and mark–recapture model reveal resource selection affects Northern Bobwhite chick survival

Justin N. Hill, Theron M. Terhune, William B. Lewis, James A. Martin

Abstract Resource selection studies have become increasingly common since the advent of modern animal tracking equipment, yet most studies fail to examine how selection affects vital rates or population growth (i.e., fitness). Without investigating if optimal habitat selection is facilitated in a …

Northern bobwhites select for native grasses on working grazing land

Douglas B. Mitchell, Patrick D. Keyser, Joseph D. Clark, David A. Buehler et autres

Abstract Northern bobwhite ( Colinus virginianus ; bobwhite) populations have experienced an 85% decline across most of its range since the 1960s. The most drastic decreases have been in the southeastern United States where biologists attribute the decline to widespread habitat loss, …

Effects of Mid-rotation Management on the Spread of Invasive Sericea Lespedeza in Working Pine Forests

William B. Lewis, Alison Colter, Daniel U. Greene, William D. Gulsby et autres

Relatively little research has focused on the spread of sericea lespedeza (Lespedeza cuneata) in working pine forests of the southeastern United States despite sericea being one of the most prominent forest invaders of this region. Timber thinning is commonly used to meet …

Estimating gopher tortoise density using a spatial distance sampling model

Craig D. Marshall, John C. Maerz, Angela L. Larsen‐Gray, James A. Martin

The gopher tortoise (Gopherus polyphemus) is an ecologically important species of conservation concern in the southeastern United States, and accurate estimates of density are crucial for monitoring population status and evaluating recovery progress. Only recently have robust methods, such as line transect …

Assessing the utility of autonomous recording units and spring point counts for monitoring abundance of ruffed grouse Bonasa umbellus

Clayton D. Delancey, William B. Lewis, Gregory T. Wann, Richard B. Chandler et autres

The ruffed grouse Bonasa umbellus is a species of conservation concern that has declined across most of its range. At the southeastern trailing edge of the range in Georgia, grouse are restricted to elevations 600 m a.s.l. and abundance is relatively low. …

Neutral effects of low‐intensity dog training on northern bobwhite vital rates

Kyle N. Magdziuk, Justin Rectenwald, D. Clay Sisson, James A. Martin

Indirect effects of hunting can lead to changes in population dynamics, which can be caused by trait‐mediated effects such as, but not limited to, changes in behavior, reproduction, and physiological responses. Our understanding of the effects of activities associated with hunting such …

Assessing the efficacy and cost‐effectiveness of integrating autonomous recording units and point‐count surveys for population monitoring of northern bobwhite ( Colinus virginianus )

William B. Lewis, James A. Martin

Abstract Autonomous recording units (ARUs) have emerged as a useful tool for monitoring a wide range of acoustically signalling wildlife species in a cost‐effective manner, but estimating abundance from acoustic data can be challenging. Wildlife management efforts would benefit from a better …
