The first part of the TPM is the probit model shown in Eq. (1), in which the explained variable is the probability of occurrence and where x,δ and F are the explanatory variable, the estimated parameter vector and the cumulative distribution function, respectively....
All PIT-tags (Biomark HPT 12) were checked for correct function using a hand-held PIT-tag scanner (Trovan LID560 and Biomark 601) both before and after insertion. During handling and tagging, bats typically remained calm and were able to fly within minutes of the procedure. Recaptured ...
