Do widely distributed butterflies suffer from fragmentation and habitat loss?
Jorge L. Len-Corts and Arcngel Molina-Martnez. El Colegio de la Frontera Sur, Ecologa & Sistemtica Terrestre, Carr. Panamericana y Perifrico Sur s/n, San Cristbal de las Casas, Chiapas, Mexico Fine-scale population and habitat data have been produced to show the distribution and abundance inter-specific relationships of a swallowtail community in a deciduous tropical fragmented forest of Southeast Mexico from May 2001 to September 2002. We quantified species-habitat associations in the current landscape to calculate population sizes and to examine likely trends in population change for the Papilionidae as a result of fragmentation and habitat reduction during the last thirty years. The relative contributions of distribution, abundance, ecological specialization and dispersal ability, have been explored as potential reasons for population changes.
