RAMIREZ-ALBORES, Jorge E. Diversidad de aves de hábitats naturales y modificados en un paisaje de la Depresión Central de Chiapas, México. Rev. biol. trop [online]. 2010, vol.58, n.1, pp.511-528. ISSN 0034-7744.

Bird biodiversity in natural and modified habitats in a landscape of the Central Depression of Chiapas, Mexico. In many parts of the neotropics, the original habitats are rapidly changing because of excessive logging, agriculture and livestock activity, with an often negative impact on bird communities. I present an analysis of the diversity and richness of birds in a fragmented landscape of the Central Chiapas Depression. Fieldwork was conducted from February 2003 to January 2004. Using point counts, a total of 35 families and 225 bird species were registered (164 residents and 61 migratory); 3% are abundant and 30% rare. Diversity, species richness and number of individuals were significantly higher in tropical deciduous forest (H´=3.41, 178 species ANOVA p<0.0001), which also had the greatest number of species restricted to a single vegetation type (39 species). The incorporation and maintenance of natural and modified habitats are necessary for the survival and reproduction of many birds species in the study area. Rev. Biol. Trop. 58 (1): 511-528. Epub 2010 March 01.
