Evaluation of Two Lures for Furbearer Scent-station Surveys

Two odor attractants, Carman's Distant Canine Call (CDCC) and W-U lure, were monitored simultaneously at scent-station transects in 5 units of the Big Thicket National Preserve, Texas. We examined transects for furbearer tracks for 3 consecutive days quarterly from January 1987 through March 1988. Significantly (X2 = 26.9, df = 1, P < 0.01) greater numbers of furbearers were attracted to scent stations with CDCC than to those with W-U lure. We recommend CDCC over W-U lure for attracting furbearers to scent stations in Southeastern pine habitats.

A Comparison of Scent-station Surveys and Track Counts for Monitoring Furbearers

Scent-station and track-count transects were monitored simultaneously in 5 units of the Big Thicket National Preserve. We examined these transects for furbearer tracks for 3 consecutive days every 3 months from January 1987 through March 1988. Greater species diversity and species richness of furbearers were recorded on track-count surveys than on scent-station surveys on 4 of the 5 study units. The number of monitoring periods with no record of a species group was compared between the 2 techniques. Track-count surveys recorded "no presence" of a species group less often than scent-station...

Movements and Habitat Use by Coyotes and Bobcats on a Ranch in Southern Texas

Movements of coyotes (Canis latrans) (N = 6) and bobcats (Felis rufus) (N = 4) on the La Copita Research Area in southern Texas were determined by radio-telemetry from April 1985 through September 1986. Mean home range sizes of resident individuals were 3.04 km2 for coyotes and 2.88 km2 for bobcats. These predators frequently traveled outside their home ranges and exhibited extensive interspecific home range overlap. Frequent travel outside the home range seemed related to subsequent dispersal. Several individuals captured on La Copita proved to be non-residents or temporary residents of...
