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.

摩洛哥特有壁虎queedenfeldtia moerens (Chabanaud, 1916)体重和猎物种类对肠道通过时间的影响

肠道通过时间（GPT）是消化过程中的一个关键因素，对消化至关重要。一些参数可能会影响GPT，如温度、胃肠道长度和体型。在这里，我们研究了来自摩洛哥中部Anti-Atlas山脉的特有日间壁虎Quedenfeldtia moerens的猎物重量和猎物种类对GPT的影响。我们使用了两种猎物，蟋蟀（Acheta domesticus，AD）和粉虫（黄粉虫，TM）。以TM幼虫期和AD若虫为食，在恒温条件下试验了猎物重量和种类对蜥蜴的影响。我们使用每种猎物的三个重量等级来测试猎物重量对GPT的影响。我们的研究结果表明，猎物物种以一种独特的方式影响GPT：与蟋蟀相比，粉虫诱导的肠道通过时间更长。此外，GPT随着两种猎物重量的增加而增加。我们的发现表明，猎物种类和体重对消化的影响，因此应该在未来的研究中更好地阐明。

期刊介绍： Acta Herpetologica, a journal open to academics all over the world, offers itself as a new site for the presentation and discussion of the most recent results in the field of research on Amphibians and Reptiles, both living and extinct. The official journal of the Societas Herpetologica Italica (S.H.I.), Acta Herpetologica publishes original works – extended articles, short notes and book reviews – mostly in English, dealing with the biology and diversity of Amphibians and Reptiles.
