Conteúdo:  The soil macroinvertebrate community, comprising all easily visible organisms found in the soil were sampled by handsorting throughout a one-year period in a seasonally dry, native grass pasture located near La Vibora, Mexico. Annual rainfall was 1420 mm, of which 84% concentrated between the months of June to October. Each month 25 samples (25x25 cm, 20 cm depth) were taken and sorted manually in the field. A total of 10 monthly samples were taken between June 1996 and May 1997. Earthworms were collected, weighed wet, preserved in 10% formalin and then separated into species and re-weighed, while the ramaining fauna were collected, preserved in 70% alcohol, separated into taxonomic orders and weighed wet. At each sample date, soil moisture and pasture biomass (green, dry, shoot and root) were also measured. The results show that soil moisture, green shhot biomass and soil fauna biomass (espec. earthworms) followed a similar pattern, with maximum values in the mid-end rainy season and minimum at the end of the dry season. Total fauna biomass ranged from a minimum of 1.3 g m-2 late in the dry season (early June) to a maximum of 49 g m -2 in mid-rainy season (September). Earthworms generally dominated the total biomass, especially in the rainy season (July-November), when they contributed more than 80% of the total. In the dry season, earthworm contribution dropped to less than 30%, when the contribution of beetles (larvae and adults), ants and lepidoptera larvae concomitantly... Mostrar Tudo
