摘要：
The influence of El Nino/Southern Oscillation (ENSO) on rainfall and its possible effect on availability of food for white-tailed deer (Odocoileus virginianus) in a tropical dry forest in the Pacific coast of Mexico was studied. From 1977 to 2003 there were three significant El Nino and La Nina events. During El Nino years rainfall decreased during the wet season ( June to October) and increased during the dry season (November to May), with the opposite effect during La Nina years. Plant diversity was monitored in permanent plots during the wet and dry seasons of 1989-1993. The results provide evidence that ENSO events affect deer food availability, particularly in the dry season.
