Structure and Dynamics of the Macrobenthic Communities of Ubatuba Bay, Southeastern Brazilian Coast
Species composition, distribution, density, biomass, diversity and trophic relationships of the macrobenthic communities in Ubatuba Bay, southeastern Brazilian coast, were investigated seasonally from August 1995 to June 1996. Sampling was carried out at 9 stations of between 4 and 13 m depth and taken in duplicate with a 0.1m2 van Veen grab. Two hundred and five macrofaunal species were identi...
متن کاملHypoxia in Chesapeake Bay Tributaries: Worsening effects on Macrobenthic Community Structure in the York River
We assessed the effects of hypoxia on macrobenthic communities in the York and Rappahannock Rivers, Chesapeake Bay, in box-core samples before and after hypoxic episodes in 2003 and 2004. Hypoxia occurred in both years and was associated with a decrease in biomass and a shift in community structure toward opportunistic species in both rivers. Long-term data indicate that the frequency of hypoxi...
متن کاملEvaluation of Southern Hawkes Bay Coast
SUMMARY 1) The use of presence/absence data is a valid method for comparing communities from hard shore marine environments where the biota is relatively sessile. It is an extensively used method in botanical surveys and its use should be extended into the marine environment. 2) Blackhead had the highest species richness and the widest range of species diversity, suggesting a diversity of habit...
متن کاملBiological assessment of river Haji Abad (Hormuzgan province) Using Macrobenthic Community Structure
This study aimed to investigate the population structure of benthic communities in Haji Abad River, West of Hormuzgan province. The study was conducted from October 91 till September 92. The three sites were determined based on regional topography and large benthic fauna. Sampling was performed monthly using a 500 micron Surber sampler with three replicates at each station. Samples were fixed i...
متن کاملEffects of sediment disturbance caused by bridge construction on macrobenthic communities in Asan Bay, Korea.
Changes in soft-bottom macrobenthic communities and the effects of anthropogenic disturbances were studied. We compared biological and environmental samples during and after bridge construction (DBC and ABC). Significant differences were detected in sediment composition at three stations, although hydrographic conditions were similar for DBC and ABC samples. From DBC to ABC, the number of speci...
