Diversity and distribution of soil invertebrates in Cu Lao Dung district, Soc Trang province

Abstract

Soil invertebrates were sampled in rainy season (August 2019) from three habitats: perennial garden, short-term garden and mangrove edge of Cu Lao Dung district, Soc Trang province. A total of 41 species, belonging to 35 genera in 25 families were recorded. Among them, spiders is the most diverse group with 21 species, followed respectively by earthworms 07 species, centipedes 05 species, landsnails and millipedes 04 species each. For the first time, one order, three families, eight genera and ten species of Mesofauna group were recorded in Vietnam. Statistical results indicate that Mesofauna groups have little difference in species diversity among the three habitats but distribution density tends to decrease towards the sea. It is suggested that pH of soil may contribute to the distribution of soil invertebrates in this area.
