Macroinvertebrados de hojarasca y suelo en selva baja caducifolia y zonas perturbadas

Abstract

To study the impact of changing land use due to the construction of roads on macroinvertebrate communities and their presence in lowland analyzed caducifolia in the watershed House, municipality of Autlan, Jalisco-Mexico, the composition of macroinvertebrates in litter and soil was determined. Samples were taken randomly in litter and soil to a depth of 30 cm; sampling units were quadrants of 30 x 30 cm. The individuals collected were counted, described and identified to the family level using dichotomous keys, reference collections and illustrated identification guides. The species richness and diversity of the communities identified were estimated using the Margalef and Shannon indices. The sampling unit (SU) with greatest species richness and biological diversity of macroinvertebrates was the SBC in litter with Da = 3.59 and H′ = 2.98. Respectively inventory obtained functional groups was identified: soil engineers, detritus, herbivores, predators.
