Dinámica biológica y química en pozas de una quebrada intermitente de la región Tumbesina.

Abstract

Abstract: Lately, a renaissance has been observed in the study of the ecology of temporary ponds, whose biodiversity varies in response to biotic, abiotic and cyclical factors, making them suitable habitats for studying the internal dynamics of these ecosystems, for example in a dry forest Tumbesino. We describe changes in composition and structure of macroinvertebrates in temporary ponds. We evaluate the changes in the physical-chemical characteristics of temporary ponds and how these characteristics are controlling the changes in the composition of macroinvertebrates. The physico-chemical variables were tested with ANOVA. The differences in the community of macroinvertebrates were analyzed with PERMANOVA and RDA to understand the relationship in the composition of macroinvertebrates according to the type of pond and date. The most abundant macroinvertebrate genera were Helicopsyche, Pelocoris and Simulium. The biodiversity indices showed significant differences between dates. The F value of the date factor was 7.1528 higher than the F value of underground flow 4.0167. We conclude that in the composition of macroinvertebrates, the behavior of ponds at a chemical and physical level was altered by groundwater sources and seasonality.
