Intertidal macrofaunal communities in an intensely polluted estuary
Environmental Monitoring and Assessment, 2007The Bilbao estuary (northern Spain) has suffered a serious environmental deterioration due to industrial and domestic discharges during decades. A total of 21 sampling stations were selected in order to: (1) study the intertidal fauna distribution on both hard and soft bottoms; (2) link this information with the prevalence of certain environmental ...

Using macrofaunal communities to inform estuarine classification
Marine and Freshwater Research, 2018Worldwide, geomorphological classifications of estuaries are often used to guide the design of monitoring programs and management strategies. However, if classifications do not reflect biotic patterns, the effectiveness of monitoring and management is potentially reduced.

While the physical characteristics of sandy beaches play a significant role in shaping the macrofaunal community features through morphodynamics, regional environmental factors may also account for deviations from the expected patterns. Here, we assess the concurrent effects of local morphodynamic factors and regional variables, such as sea surface ...

A More Cost-Effective Emap Benthic Macrofaunal Sampling Protocol
Environmental Monitoring and Assessment, 2006Benthic macrofaunal sampling protocols in the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program (EMAP) are to collect 30 to 50 random benthic macrofauna [defined as animals retained on a 0.5 mm (East and Gulf Coasts, USA) or a 1.0 mm mesh sieve (West Coast, USA)] samples per reporting unit using a 0.044 m(2) (East ...

A. - Mollusques testacés (Macrofaune)/ Testaceous mollusks (macrofauna )
Géologie Méditerranéenne, 1979The ecological study of the Kerkennah Plateau showed 3 environmental groups : 1) those living in the Posidonia thickets ; 2) those in the Caulerpes and Cymodocea prairies ; 3) those in the sediments. There appears to be a particular molluscan stock characteristic or preferential to each of these biotopes, but overall differences ...

Macrofaunal community bioturbation along an estuarine gradient
Netherlands Journal of Aquatic Ecology, 1993A multidisciplinary study of the impact of bioturbation on sediment dynamics has been underway for some time at the Plymouth Marine Laboratory. The current programme has been founded upon the careful selection of six sites in the River Tamar, representative of important combinations of physical and biological variables.

Macrofaunal Diversity in the Gulf of California
2005Abstract The Gulf of California (Sea of Cortez) has held a growing fascination for naturalists over the past 150 years (Lindsay 1983). The first serious collectors of marine life in the region were not professional bi-ologists. One was John Xantus (de Vesey), a U.S.

Macrofaune des fonds de cailloux du Léman
Schweizerische Zeitschrift für Hydrologie, 1974In Lake Geneva (Switzerland), the macrofauna of the stony lake bottom was studied in seven stations from 1969 to 1971. The modifications in animal communities since the beginning of the century can be attributed partly to the increasing eutrophication of the lake and partly to the introduction of new species.

Benthic Macrofaunal Production of Browns Bank, Northwest Atlantic
Canadian Journal of Fisheries and Aquatic Sciences, 1989Benthic macrofauna of the coarse sediments of Browns Bank, off southwest Nova Scotia, Canada were sampled with a modified 0.5-m2 Van Veen grab; 29 stations from 1983 to 1985. Production was estimated from alcohol-stored biomass by multiplying by the annual turnover ratio, P:B, of each species.
