Knowledge of the spatial distribution of rodents around kangaroo rat burrows may help us to understand the role that kangaroo rats play in the spatial organization of small desert rodent communities. In this study we analyzed the pattern of proximity between capture locations of desert rodents and burrows of Dipodomys merriami insularis, and descri...

... study population of D. merriami insularis is located in a 79.8 ha (1050 m × 760 m) area in San José Island, Gulf of California, México (24.9291 to 24.9227N, 110.635-110.6294W and 24.933-24.9258N, 110.6294-110.6236W; Fig. 1). Individuals were live-trapped from March to May and from October to November 2008. The sampling periods included the rainy and dry seasons, respectively (Salinas-Zavala et al. 1990). Reproductive individuals of D. m. insularis are found during February and March (Best and Thomas 1991). In this study, we found the highest prevalence ...

... GIS has a wide range of application in different aspects including national security and fuzzy territorial border conflict [2]; underground water quality, water measurement and urban water supply service [3]; observing the physiological activity of a population and taking actions to protect endangered species [4], etc. Implementing GIS into reservoir resettlement will definitely improve the efficiency of migration management work as well as ensure the smooth process of resettlement project. ...
Over recent decades, dispersal and philopatry in natural populations have been addressed together. However, philopatry, or the tendency of an individual to remain in its birthplace, has received little attention, despite the fact that this trait is present in a considerable number of vertebrates. In this paper we discuss hypotheses that state philopatry generators: life-history variables, ecological constraints, benefits of philopatry and agonistic behaviors. Additionally, we propose that genetic microstructure may be an outcome of such behavior. We conducted an analysis based on the above hypotheses in order to explain the presence of philopatry in rodents of arid environments. En las últimas décadas, la dispersión y la filopatría han sido abordadas en conjunto. La filopatría o la tendencia de un individuo a permane-cer en su lugar de nacimiento, es un comportamiento ampliamente observado entre los vertebrados. Aún así, tal comportamiento ha recibido poca atención. En este trabajo, se discuten hipótesis como las variables en las historias de vida, las restricciones ecológicas, los beneficios de la filopatría y los comportamientos agonísticos como generadores del comportamiento filopátrico. Adicionalmente se propone que la microes-tructura genética puede ser resultado de tal comportamiento. Realizamos un análisis basado en las hipótesis previas para explicar la presencia de filopatría en roedores de ambientes áridos.
