          Abstract

          Resumen: La fragmentación del bosque seco tropical (BST) en el Caribe colombiano ha dejado como producto fragmentos de bosques inmersos en una matriz de usos ganaderos y agrícolas donde se encuentran comunidades de escarabajos de las cuales se desconoce su dinámica espacial y temporal. Por tal razón, comparamos la variación espacio-temporal de los ensamblajes de escarabajos copronecrófagos (Scarabaeidae: Scarabaeinae) en 3 localidades en el departamento del Atlántico (Corrales de San Luis [CSL], Reserva Campesina La Montaña [RCM] y Reserva Bijibana [RB]). En cada una se localizaron fragmentos de bosque y la matriz adyacente (cercas vivas, potreros y cultivos) instalándose en cada uno 10 trampas de caída durante 2 muestreos por temporada: primeras lluvias, lluvias fuertes y seca. Fueron capturados 34,170 individuos agrupados en 15 géneros y 32 especies. El análisis de interpolación y extrapolación mostró que los mayores valores de riqueza se presentaron durante las primeras lluvias en la cerca viva de la RCM (22 especies) y los menores en CSL para cultivo y potrero en la temporada seca (2 especies). Con la prueba de similitud ANOSIM se demostró que los fragmentos de bosques presentan composición y estructura de la comunidad de Scarabaeinae diferente a los hábitats de uso antrópico.

          Abstract: The fragmentation of the tropical dry forest in the Colombian Caribbean has left forest fragments immerse in matrices of livestock and agricultural uses, where dung beetle communities are found and about which little is known on their spatio-temporal dynamics. Therefore, a comparison of the spatio-temporal variation of copro-necrophagous beetles assemblage (Scarabaeidae: Scarabaeinae) was conducted between forest patches and their adjacent matrix (cropland, paddocks, living fences) in 3 locations (Corrales de San Luis [CSL], Reserva Campesina La Montaña [RCM] y Reserva Bijibana [RB]). Two samplings were carried out in each season (first rains, heavy rains and dry) and for every forest patch and adjacent matrix 10 pitfall traps were buried. A total of 34,170 beetles was collected belonging to 15 genera and 32 species. The analysis of interpolation and extrapolation showed that the highest diversity values are found during the first rains in the living fences of RCM with 22 species and the lowest values were observed in cropland and pasture of CSL during the dry season (2 species). The ANOSIM test proved that forest patches have differences in the composition and structure of Scarabaeinae community in relation to the other habitats with anthropic impact.
