Abstract: | Cortisol and aldosterone levels were measured in plasma of eastern cottontail rabbits (Sylvilagus floridanus) collected by three different methods, i.e., shooting, live-trapping and falconry. Cortisol levels ranged from near 0 to 27.5 micrograms/100 ml and aldosterone from near 0 to 220 ng/100 ml. Shot animals had significantly lower cortisol concentrations than those taken by either of the other methods. Trapped cottontails also had significantly lower aldosterone levels. |
