N estuarine and marine ecosystems—e.g., seagrass meadows, marshes, and mangrove forests— serve many important functions in coastal waters. Most notably, they have extremely high primary and secondary productivity and support a great abundance and diversity of fish and invertebrates. Because of their effects on the diversity and productivity of macrofauna, these estuarine and marine ecosystems a...

Abstract Although chickens can improve the chemical properties of soil through deposition excreta, their effects on macrofauna are poorly known. This work assessed grazing indigenous laying hens two agroecosystems in Portugal: an organic horticultural field and a conventional orchard. At field, were used to control weeds results compared with those other weed treatments: mechanical (rototiller)...

Commercial fishing is one of the most important human impacts on the marine benthic environment. One such impact is through disturbance to benthic habitats as fishing gear (trawls and dredges) are dragged across the seafloor. While the direct effects of such an impact on benthic communities appear obvious, the magnitude of the effects has been very difficult to evaluate. Experimental fishing-di...

Macroinvertebrates are widespread in lake sediments and alter sedimentary properties through their activity (bioturbation). Understanding the interactions between bioturbation sediment is important given that lakes sinks sources of carbon nutrients. We studied biogeochemical impact macrofauna on surface 3-month-long mesocosm experiments conducted using cores from a hypoxic, macrofauna-free basi...

As diferentes coberturas vegetais formam sobre o solo uma camada que serve como abrigo de diversos organismos. Entre estes, destaca-se a macrofauna epiedáfica, desempenhando importantes funções melhoria e manutenção da qualidade do solo. Diante exposto, objetivo trabalho foi avaliar epiedáfica associada usos na região Sudoeste estado Paraná. A avaliação realizada pela instalação armadilhas qued...

Microbiological activity is a general term which includes all metabolic reactions and interactions of the soil microflora and macrofauna.1 Soil microorganisms contribute to soil fertility and aggregate formation in degraded soils.2 However, it is only during the last decades that ecologists have beginning to explore the underground communities and their functional significance for the plant com...
