Distribución altitudinal de la mastofauna en la Reserva de la Biosfera "El Cielo", Tamaulipas, México
2001
The Biosphere Reserve "El Cielo" is one of the most important areas in Tamaulipas, Mexico, holding a rich biodiversity. This reserve embraces tropical semideciduous forest, cloud forest, pine-oak forest and dry scrub, which possess a unique fauna. Here, we determined which mammals were associated to each vegetation type. We observed five distributional patterns for mammals along an elevational gradient: four species with a wide distribution, seven species with a medium distribution, 31 species with a reduced distribution, 12 species with leap frog distribution, and 42 species with a specific distribution. Furthermore, tropical semideciduous forest have more species (19) with specific distribution that cloud forest (10), dry scrub (9), and pine-oak forest (4). Simpson’s index was used to measure species similarity among habitats. A high percentage of shared species was found between tropical deciduous forest and cloud forest (72.54%), in comparison with other habitats; whose values varied between 28.57 and 58.33%. Meanwhile, pine-oak forest and dry scrub shared few species with other habitats and their values of similarity are between 28.57 and
