RESERVORIOS DE VEGETACIÓN: ¿CUÁNTOS Y CÓMO?

Diego Griffon, María Josefina Hernández

Resumen


En este trabajo se estudia, en una aproximación teórica, las características generales que debe tener una red de reservorios de vegetación (parches) para que ésta pueda servir de fuente de controladores biológicos. Para esto se utiliza el Modelo de Función de Incidencia, con base en el cual se establecen las características generales que debe tener una red en cuanto al número, tamaño y ubicación espacial de los diferentes parches, de manera que estos tengan altas probabilidades (incidencias) de albergar controladores biológicos. En este sentido, las simulaciones efectuadas muestran que bastan sistemas de aproximadamente 10 parches (equivalentes en su conjunto a 5% del área total en evaluación) para obtener incidencias promedio cercanas al 50% y que el factor fundamental a tomar en cuenta es la heterogeneidad en el tamaño de los parches.
