Funnel Traps May Be Inappropriate for Many Studies of Semi-Aquatic Snakes

摘要: ABSTRACT We conducted a study to test whether funnel traps anchored brush piles constructed at the edge of aquatic habitats largely devoid cover would increase catchability semi-aquatic snakes in these systems. Brush pile captured significantly more and potential snake prey than placed water along pond banks 2000, but not 2001. Changes hydrology during 2001 may explain disparate results. Additionally, we used quantitative anecdotal data from our as well others literature provide critical broad overview trapping for habitats. conclude that trap design deployment must address mortality caution against using studies diet, habitat use, activity, growth actively seek out forage on sequestered traps.
