Abstract: The use of the matrix has been considered an important factor in landscape ecology, as it can change the relationship of the population with the configuration of the landscape. There are indications that the usability of the matrix is a factor that can help mitigate the effect of further fragmentation. Using a systematic way to assess the effect of matrix quality in fragmented landscapes could lead to a better understanding of this system. We built a computational individual-based model capable of simulate bi-dimensional landscapes and individuals that inhabit that landscape. We explored how changes in the level of fragmentation and matrix quality affected time of permanence of a single population in the landscape. As the quality of the matrix changes from very unsuitable to very suitable, the number of situations in which fragmentation reduces the time of permanence of the population changes from frequent to rare. In addition, as most of the organisms can survive in a sub-optimum habitat, the cases in which fragmentation has Copy rights belong to original authors. Visit the link for more info
