Abstract The macroecological variable of patchiness (Lloyd’s I p index patchiness, P ) has recently been shown to be related inter- and intraspecifically those abundance (numbers m ?2 , A ), occupancy (% occurrence in samples, O lower latitude seagrass macrofaunas. For the first time higher latitudes, intraspecific relationships between three spatial variables were investigated intertidal mudfl...

Abstract. The availability of standardised biomass data is essential for studying population dynamics, energy flows, fisheries and food web interactions. To make the estimates consistent, weight-to-weight conversion factors are often used, example to translate more widely available measurements wet weights into required dry ash-free weight metrics. However, many species groups applicable freely...

The study presents the result of a new attempt for benthic biotopes remote sensing in the southern coast of the Qeshm Island in the Persian Gulf. This survey site covers approximately 233 km2 in water depth between five and 25 m. Bathymetric data was derived from the single beam survey and grab stations, underwater video and photos were undertaken as ground-trusthing. The acoustic results showe...

The Mediterranean Sea is one of the most exploited regions world’s oceans. Here industrial activities have determined either acute or long-term impacts on coastal marine ecosystems. In this study, we investigated macrofauna distribution and diversity, food-web functioning in a area facing an chemical plant abandoned ‘90s to assess benthic ecosystem health. This has been identified as Site Natio...

The ecotoxicological effects of oil spill from the grounded vessel MV River Princess on the intertidal benthic organisms of Sinquerim-Candolim beach at Goa were investigated. An intertidal expanse of 1 km on either side of the grounded vessel was selected to evaluate the concentration of total petroleum hydrocarbon (TPH) in the sediment and its effects on the composition, abundance and diversit...

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...

Studies focusing on the linkage between numerical and functional trait diversity frequently consider functional diversity indices but rarely evaluate them empirically or evaluate the use of other than continuous traits such as body size. Here, we present an extensive compilation on functional knowledge of benthic macrofauna using the categorical trait approach and scores of both common and rare...
