Biodiversity and community structure of macrofauna of the intertidal sandy beach at Chabahar Bay were studied for a period of ten months in 2007. A total of 32 species were observed and identified in this study so that polychaete with 16 species was numerically dominant. The results showed changing densities were influenced by monsoon season so that maximum density (1935.47 ind/m2) was observed...

(1) Background: Coffee agroforestry systems (CAFS) in Veracruz, Mexico, are being displaced by avocado monocultures due to their high economic value. This change can generate alterations the type of organic residues produced and soil biological activity (SBA) which is sensitive climatic variations, changes floristic composition, agronomic management. It be evaluated through respiration macrofau...

Earthworms are important soil macrofauna inhabiting almost all ecosystems. Their biomass is large and their burrowing and ingestion of soils alters soil physicochemical properties. Because of their large biomass, earthworms are regarded as an indicator of "soil heath". However, primarily because the difficulties in quantifying their behavior, the extent of their impact on soil material flow dyn...

Conventional agricultural in the Venezuelan Llanos has generated gradual soil degradation. Therefore, conservationist agriculture been proposed. According to several works, this type of management favors macrofauna. To test hypothesis, response macrofauna establishment maize crops, associated with Brachiaria dictyoneura (Bd) and Centrosema macrocarpum (Cm), was evaluated. The samples were taken...
