Abstract

Gut passage time (GPT), a key factor in digestive procedure, is of pivotal importance for digestion. Several parameters may affect GPT, such as temperature, length of gastrointestinal tract and body size. Here, we examine the influence of prey weight and prey species on GPT in the endemic diurnal gecko Quedenfeldtia moerens, from the Anti-Atlas Mountains in central Morocco. We used two prey species, house crickets (Acheta domesticus, AD) and mealworms (Tenebrio molitor, TM). Lizards were fed with the larval stage of TM and nymphs of AD. The influence of prey weight and prey species was tested at a constant temperature. We used three weight classes of each prey species to test the influence of prey weight on GPT. Our results showed that prey species affected GPT in a distinct way: mealworms induced a longer gut passage time compared to house crickets. Moreover, GPT increased with the increasing weight of prey for both prey species. Our finding demonstrates that the effect of prey species and prey weight affect digestion and thus should be better clarified in future studies.
