Abstract Floodplain ecosystems are hotspots of biological diversity and perform important ecosystem functions in the landscape. The key to understanding sustainability function is knowledge relationships between components. article reveals role morphological physical properties soil, as well phytoindication environmental factors drivers soil macrofauna protected Dnipro River floodplain. studies...

Os sistemas agroflorestais mitigam os impactos causados pelo manejo insustentável da agricultura contemporânea. A fauna edáfica promove serviços ecossistêmicos e pode ser considerada um bioindicador qualidade do solo. Este trabalho teve como objetivo caracterizar a diversidade macrofauna por meio de amostragens aliada aplicação cromatografia Pfeiffer em pomar Santana Livramento (RS). Dentre as ...

Beecher's Trilobite Bed in the Frankfort Shale of New York State preserves an exceptional record of the benthic macrofauna of a Late Ordovician deepwater marine environment. It has long been famous for specimens of the trilobites Triarthrus eatoni (Hall), Cryptolithus bellulus (Ulrich), Primaspis crosotus (Locke), and Cornuproetus beecheri (Ruedemann), new combination, which preserve the ventra...

Introduction The purpose of many ecological studies is to identify interactions between faunistic ecosystem components by means of laboratory and field experiments. It has often been shown that abiotic and biotic factors such as competition, disturbance and predation influence the composition and dynamics of macrobenthos communities (REISE, 1977; COMMITO and AMBROSE, 1985; AMBROSE, 1986; BEUKEM...

Coral reef lagoons are generally regarded as zones of net heterotrophy reliant on organic detritus generated in more productive parts of the reef system, such as the seaward reef flat. The abundance and biomass of sediment infauna were measured seasonally for one year (1986) within the lagoon of Davies Reef, central Great Barrier Reef, to test the hypothesis that macrofaunal biomass and product...

Despite the complexity of natural systems, heterogeneity caused by the fragmentation of habitats has seldom been considered when investigating ecosystem processes. Empirical approaches that have included the influence of heterogeneity tend to be biased towards terrestrial habitats; yet marine systems offer opportunities by virtue of their relative ease of manipulation, rapid response times and ...

DNA barcoding, as it is currently employed, enhances use of marine benthic macrofauna as environmental condition indicators by improving the speed and accuracy of the underlying taxonomic identifications. The next generation of barcoding applications, processing bulk environmental samples, will likely only provide presence information. However, macrofauna indices presently used to interpret the...

Infralittoral soft-bottom macrofauna abundance data collected during four-year surveys after the Aegean Sea (Galicia, Spain) and the Amoco Cadiz oil spill (Brittany, France) at a total of seven sites were analysed at three different taxonomic levels (species, genus, and family). The effects of the spills on macrofauna populations were very similar in the two areas. The post-spill time-courses o...

The present paper examines the functional diversity-environment relation in a placer rich tropical bay. Understanding the environmental variables that determine the biodiversity pattern will help in the effective conservation plans of coastal habitat. However, few studies have been carried out on the biodiversity-environment relation from the diverse tropical coastal ecosystem. The geographic l...

Natural disturbances along with human interference make the tropical estuaries amongst the most disturbed areas globally. In spite of this, information on the seasonal variability of macrofauna from tropical estuaries is few. Temporal variability of macrofaunal community from Mormugao Bay, Zuari estuary, on the west coast of India was examined from 2003 to 2004 at seven stations. Environmental ...
