RESUMO
Brazil is considered a megadiverse country, but the soil fauna is still very poorly known. The aim of this study was to report, for the first time, the abundance and genus composition of terrestrial enchytraeids (Enchytraeidae, Oligochaeta) in Savanna Tall Woodland (Cerradão) and a pasture in Cerrado Biome and in Upper Montane Atlantic Forest and a grassland in Atlantic Forest Biome. The enchytraeid density in Pasture and Cerradao was 2,036 and 18,844 (204 and 2,094, on average) individuals per square meter, respectively. At the Atlantic forest and Grassland, density was 9,666 and 12,242 individuals per square meter (1,075 and 1,471 on average). About genus composition for the studied areas, Enchytraeus and Hemienchytraeus were found in the four ecosystems evaluated, while Tupidrilus and Fridericia were found only in Cerradão and Atlantic Forest, respectively. Achaeta was absent in Upper Montane Atlantic Forest, but dominant in pasture, while Guaranidrilus was absent in Pasture, but predominant in the other ecosystems.

Caramujos aquáticos são importantes por algumas das espécies desses agentes atuarem como hospedeiros intermediários de Fasciola hepaticae de Schistosma mansoni, agentes que podem causar enfermidades no homem e em animais domésticos. Conhecer a distribuição desses agentes é importante, porque nos possibilitaria predizer se casos autóctones dessas helmintoses poderiam ocorrer para uma devida região. Existem diversos outros caramujos aquáticos que são competidores com esses moluscos aquáticos indesejáveis. Dessa forma, ter conhecimento da presença desses outros moluscos competidores torna-se também importante. Dessa forma, estabeleceu-se nesse trabalho como intento de investigar quanto à ocorrência de caramujos aquáticos no sul do estado do Espírito Santo. Para isso, algumas localidades foram visitadas e investigadas quanto a presença de caramujos aquáticos. Os mesmos foram coletados e identificados. Foram identificados diversos gêneros de caramujos aquáticos como do gênero Lymnaea, Biomphalaria e Melania sp. (AU)
Aquatic mollusks are important because some of the species of these agents act as intermediate hosts for Fasciola hepatica and Schistosma mansoni, agents that can cause disease in humans and domestic animals. Knowledge of the distribution of these agents is important because it would enable to predict whether autochthonous cases these helminthiasis could occur for a proper region. There are several other aquatic snails that are competitors with these undesirable aquatic mollusks. Thus, being aware of the presence of other competing mollusks also becomes important. Thus, this work has established itself as attempt to investigate regarding the occurrence of aquatic mollusks in the southern state of Espírito Santo. For this, some localities were visited and investigated for the presence of aquatic snails. They were collected and identified. We identified several genus such as aquatic mollusks of the genus Lymnaea, Biomphalaria and Melania.(AU)
