Spatial patterns of population abundance: a review of predictions and theoretical models in ecology and biogeography: The search for mechanisms influencing population demographic patterns has continuously increased. The early models described how closed populations performed, considering only local demographic attributes. However, the spatial configuration and dispersal rates in demographic patterns become determinant factors for understanding patterns of distribution and abundance. As a result, spatially explicit models have been improved to be analytically tractable by using computer simulations. Because species are not infinitely disperse, here I investigated the theoretical predictions to understand what determine range boundaries and distribution patterns, as well as abundance patterns over species ranges. I conclude that empirical studies are crucial to a more accurate understanding of population dynamics along space and time to validate the theoretical predictions made about the geographic distribution of species.
