摘要: Abstract Detection of non-target species during distribution surveys may influence the detection focal species, due to bait being consumed, or trapping devices inactivated. The aim this work was evaluate effect (field mice, Apodemus sp.) on and occupancy estimates a target (the red squirrel, Sciurus vulgaris) hair-tubes surveys. Following modelling approach that accounted for imperfect both we tested hypothesis probability squirrel is affected by field mice. We also investigated level bias occurred in estimation key-parameters such as presence probability. Our results show squirrels mice using not independent. higher when did visit hair-tubes. Nevertheless, there no parameter ...
