We evaluated the detection rate for hair snare sampling for bobcats (Lynx rufus) using colocated hair snares and infrared-triggered cameras at 20 locations on private property in eastern Texas. Hair snares and cameras were placed together at survey stations that included both visual and olfactory attractants. In 1,680 trap-nights we photographically documented 15 visits by bobcats but collected only one bobcat hair sample. Our observations suggested limited rubbing behavior by bobcats at hair snares despite presence at hair collection stations. The explanation for this behavior remains unclear but is consistent with observations of low and variable hair trap …

Texas Black Bears, Alexandria Bryant
Undergraduate Research Conference
One way to promote conservation efforts in an area is to bring awareness of the connections our society has with the animal that is under threat. Black Bears were once abundant throughout Texas, but through hunting and habitat loss, the bears had been eliminated from Texas by the 1950s. The placing of the Louisiana subspecies as threatened under The Federal Endangered Species Act in 1922 allowed populations to recover in Louisiana, and there have been several sightings in East Texas since. The face of Texas has been forever altered byt the presence of black bears. From the forests of East …

Early accounts describe the Cooper’s Hawk (Accipiter cooperi) as a species in decline in much of North America during the early twentieth century (Bent 1937), particularly when in close proximity to humans (Eaton 1914). This decreasing population trend continued to be recognized later in the century in both Texas (Oberholser 1974) and Louisiana (Lowery 1974). Shooting and trapping during the first half of the 1900s, and pesticide use (especially DDT) after World War II are suggested as primary causes of the decline (Henny and Wight 1972, Bednarz et al. 1990). The Migratory Bird Treaty Act of 1972 and the ban …
