Popis: Analysis of bladder urine of small mammals collected during the summer in Michigan shows that: 1. 1. Snap-trapping rodents and insectivores can be an effective technique for collecting natural urine. 2. 2. Individuals not immediately killed by the trap produce abnormally concentrated urine. 3. 3. Natural urine is very dilute compared to maximum concentrating abilities of the species tested. 4. 4. Brief periods of captivity (< 2 hr) do not significantly affect urine concentration in Eptesicus fuscus.
