Does Body Condition Affect Immediate Post-Capture Survival of Ungulates? by Louis C. Bender

“…Survival was not affected by number of times an individual previously had been captured, rectal temperature during handling, or mode of capture (helicopter darting or net-gunning). Individuals in poorer condition were not predisposed to capture-related mortality despite a significant proportion of individuals being in poor condition at capture (i.e., 60 to 67% of individual elk and mule deer 7% BF in late winter or >12% BF in late-autumn captures for mule deer and elk; and individuals with 0 cm of subcutaneous rump fat versus 1.5 cm for pronghorn) never differed among individual captures or species (Fisher’s exact P > 0.14). …”
