Se llevó a cabo una revisión de información biofísica existente sobre Brosimum alicastrum Sw. en la costa del Pacífico mexicano, con la finalidad de identificar y caracterizar zonas, de acuerdo con sus principales atributos ecológicos, así como relacionar algunas variables ambientales con la densidad y área basal de esta especie arbórea. Se determinaron 22 zonas ecológicas dentro de cinco tipos de vegetación y fue en la selva mediana subperennifolia donde Brosimum alicastrum presentó su mayor abundancia y desarrollo. La precipitación, altitud y capacidad de almacenamiento de agua en el suelo fueron las variables que mejor explicaron la variación ecológica de la especie en su área de distribución.
Agriculture has intervened, modified, and simplified ecosystems to obtain some goods and services. Conventional o industrial agriculture emphasizes the use of external inputs and the homogeneity of the landscape; agroecology promotes biodiversity to maximize biological interactions and their ecosystem services. The objective was to evaluate agrobiodiversity and its trophic interactions as an indicator of sustainability by comparing: industrial productive systems, and agro-ecological and semi-natural sites in the southern Pampas region. Samples were taken of mammals, birds, arthropods, and vegetation; with different indices, the food chains and the state of the system were evaluated. The results show that agricultural intensification simplifies landscape structure with a loss of biodiversity and the absence of functional groups (herbivores and nectarivorous). In agroecological wheat, the highest density of links was found and in agroecological pastures the highest grouping coefficient, this reveals greater cohesion and integration among the components of the system and more mechanisms of self-regulation. The agroecological diversity Index showed no differences between the management, this could be related to the presence of a biological corridor in the conventional field that would be increasing biodiversity. The key to achieving sustainable agroecosystems is to procure biodiverse landscapes with patches and corridors of shrub and herbaceous species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
