Gestion de la construction de la toile chez une araignée orbitèle, Zygiella x-notata : Perception et utilisation des informations du milieu

Abstract : During their life, animals may adapt their strategies to maximise their fitness. They have to make choices, and their behaviour should take into account environmental variations. In many works, it has been showed that animals take into account one environmental variable; but they live in complex environments, and have to integrate simultaneously several information. Until now, there are very few data on that. We tackled this problem in an orb-weaving spider, Zygiella x-notata. Observations on natural populations of spiders showed they adapted their web building behaviour to prey and the presence of neighbours. In the laboratory, when spiders were put simultaneously in the presence of prey and conspecifics, they exhibited a web building behaviour similar to that they showed when they were in the presence of prey only. Complementary tests showed that, in this situation, spiders perceived prey and conspecifics. These results could be explained in two ways: 1) in the multi-variable environment, spiders could organize information into a hierarchy, and choice prey, or 2) when they receive simultaneously several information, they have not the cognitive abilities to treat them.
