Regeneration of Quercus spp. along interactive forest boundaries in a fragmented peri-urban landscape of Mexico City

摘要: Biodiversity conservation in forest fragments surrounded by a low-quality matrix requires an understanding of how ecological conditions prevailing the enter and interact with local habitat conditions. We assessed regeneration oak species along edge–interior gradients at periphery Mexico City. The abundance saplings was sampled transects to forest, while edge effect analysed using segmented zero-inflated Poisson models for data. Three were dominant terms their relative abundances: Quercus laeta, castanea obtusata. Regeneration nine responded nonlinearly distance, greater sapling from up 10 m into fragment. Canopy cover tree height decreased fragment interior, increased open areas within (i.e., independent distance). A posterior analysis indicated that Q. obtusata reacted positively edges. These results indicate is promoted suitable near boundaries. Therefore, we suggest management should focus on promoting seed production establishment interior habitats.
