Publisher's Synopsis
The soil is a fundamental element in human life. It plays important roles in production by acting on the recycling of organic matter, water purification as well as various other environmental services through the biological diversity that it harbors. Nematodes are part of the soil inhabitants, regulators of microorganisms in the soil trophic chain and bio-indicators for monitoring the biological quality of soils. This study aims to know the dynamics and abundance of nematodes according to the occupation and the mode of use of the soil and to study the nature of the pedological pit in various ecosystems located in the commune of Tsaramandroso and Marosakoa. Among these ecosystems, nematodes are abundant in the forest ecosystem. This abundance depends on many factors such as soil temperature, texture, structure, organic matter content and moisture content.
