During this survey, twelve species were identified, including one alpheid shrimp (Alpheus lobidens), three Anomura (Petrolisthes rufescens, Porcellana persica, Clibanarius signatus) and eight Brachyura (P...

In this paper we describe an individual-based model to account for the growth and morphogenesis of networks of galleries in the ant Messor sancta. The activity of the individuals depends only on their local perception of the immediate surroundings. Coordination between ants arises from the modifications of the environment resulting from their activity: the removal of sand pellets and a pheromon...

conclusions the results of the present study revealed that soil resources of these areas were contaminated with opportunistic amoebas such as acanthamoeba and hartmannella spp. and this may lead to severe diseases in high-risk people, such as immunocompromised patients. background free-living amoebas are very abundant in nature, especially in water and soil. some species of amoebas cause seriou...

Environmental conditions and physical constraints both influence an animal's behavior. We investigate whether behavioral variation among colonies of the black harvester ant, Messor andrei, remains consistent across foraging and disturbance situations and ask whether consistent colony behavior is affected by nest site and weather. We examined variation among colonies in responsiveness to food ba...
