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 ...

A yearlong seasonal survey was carried out during 2016–2017 at 26 stations representing four tidal channels of the north-western part Gulf Gabès (Tunisia). The area studied (characterized by a maximum range 2.3 m) subjected to diverse anthropogenic pressures: from phosphate industry and its metallic pollution, unauthorized bottom trawling in shallow water (known locally as ‘Kiss’), organic poll...

Macrobenthos is an important component of organic carbon storage and energy flow in marine systems, including these impacted by riverine discharge high share allochthonous matter (OM). Changing environmental conditions, such as lower precipitation snow cover duration, may affect patterns input, therefore it crucial to know how benthic communities utilize different OM sources areas affected rive...

Biodiversity loss has spurred the biodiversity-ecosystem functioning research over a range of ecosystems. In Antarctica, however, the relationship of taxonomic and functional diversity with ecosystem properties (e.g., community biomass) has received less attention, despite the presence of sharp and dynamic environmental stress gradients that might modulate these properties. Here, we investigate...

1 A survey of the macrobenthos community was carried out in Lake Illawarra, NSW, Australia, during April and May 2011. 2 The aim of this study was to understand the current status of the characteristic macrobenthic fauna community, and the temporal changes over the past 30 years, as well as the impacts of anthropogenic activities on the benthic ecosystem. 3Fifteen stations were selected as repr...

Understanding the variation of biodiversity along environmental gradients and multiple spatial scales is relevant for theoretical and management purposes. Hereby, we analysed the spatial variability in diversity and structure of intertidal and subtidal macrobenthic Antarctic communities along vertical environmental stress gradients and across multiple horizontal spatial scales. Since biotic int...

Improved waste management at McMurdo Station, Antarctica beginning in the 1980s has been followed by decreases polycyclic aromatic hydrocarbon (PAH) and metal contamination adjacent marine sediments. However, determining effect of decreased on ecological indicators (macrobenthic fauna) is confounded concurrent changes climate cycles other physical forces. Between 2000 2013, there was a decrease...
