abundance

Many of the methods used to estimate white-tailed deer population parameters from camera images are reliant upon the assumption that rates of detectability are similar between both sexes and all age groups of deer. e assumption of equal detectability may not be valid when bait is used to attract deer to survey sites due to physical and behavioral differences between deer groups. We placed trail cameras set at 1-minute time-lapse intervals at randomly selected sites baited with corn inside the Auburn University Deer Research Facility, a 175-ha enclosure containing a captive population of...

Historical eradication efforts, increasing fishing pressure, and growing anthropogenic impacts have resulted in decreased abundance or extirpation of the alligator gar (Atractosteus spatula) throughout much of its historic distribution. Current population status has prompted states to actively manage stocks; however, efforts are hindered by a lack of data necessary to make informed management decisions. To begin addressing these data needs, we investigated alligator gar population dynamics and exploitation in Choke Canyon Reservoir, Texas. A total of 754 fish (total length [TL] range, 678...
