¿Son las aves bioindicadores efectivos para la evaluación de los efectos del disturbio antrópico y el cambio climático en ecosistemas estacionalmente secos?

Abstract

Abstract: Herein, we propose a system of pressure and state indicators for Zapotillo s seasonally dry tropical forests with which to determine the state of the avian community and forest under human pressure. The indicators were tested using information previously collected from 16 patches distributed along a disturbance gradient defined by livestock accessibility and forest density. Three pressure and seven state indicators were proposed and related to test effectiveness. Five of the state indicators responded significantly to two of the pressure indicators (anthropic surface area and accessibility to the forest) and degree of intervention (Altered, Shrub Dominated, Seminatural and Natural). With these, the state of the forest was determined at each patch: one was in Very good state, four in Good state, eight in Regular State and three in Poor state. To measure the indicators temporal variation, we propose the use of control charts.
