Age-structure, recruitment, and adult mortality in populations of the Atlantic surfclam, Spisula solidissima, from 1978 ...
Published in Marine Biology
The Atlantic surfclam, Spisula solidissima (Dillwyn, 1817), is a dominant member of the benthic community on the continental shelf from Georges Bank to North Carolina, USA. This bivalve has supported a major fishery, primarily off New Jersey and the Delmarva Peninsula, since the 1960s. Early papers documented that these populations were at historic...
Spatial and temporal patterns in coastal macrobenthos of Samborombon Bay, Argentina: A case study of very low diversity
Published in Estuaries
The benthic community structure of the southernmost part of Samborombon Bay was studied at 13 stations for 2 yr. A detailed examination of the zoobenthos, using similarity indices and cluster analysis, is presented. The area was characterized by low diversity. The Shannon-Weaver information diversity index H′ showed low values of 0.28–1.60. The bra...
Population biology and antipredator defenses of the shallow-water Antarctic nudibranch Tritoniella belli
Published in Marine Biology
The circumpolar nudibranch Tritoniella belli Eliot occurs in abundance in shallow-water benthic communities of McMurdo Sound, Antarctica. Density estimates based on belt transects averaged collectively 0.46 individuals m−2 at three study sites between depths of 6 and 30 m in November 1996. At two of the sites, population densities increased linearl...
Post-settlement mortality of juvenile lagoonal cockles (Cerastoderma glaucum : Mollusca: Bivalvia)
Published in Marine Biology
Like many benthic marine invertebrates the lagoonal cockle Cerastoderma glaucum Bruguière (Mollusca: Bivalvia) suffers extensive mortality between settling out of the plankton and reaching adolescence. It is thought that predation could be a major cause of this mortality. Experiments were conducted in aquaria to assess the influence of predation on...
Benthic Biological Processes and EH as a Basis for a Benthic Index
Published in Environmental Monitoring and Assessment
It is proposed that the common measures of benthic community condition can be augmented with a vertical EH profile taken through the benthic bioturbation zone. Sediment EH, an electrochemical measure of oxidized and reduced compounds in sediment porewater, measures the integrative consequences of all metabolic and transport processes of the benthic...
Relating Benthic Infaunal Community Structure to Environmental Variables in Estuaries using Nonmetric Multidimensional S...
Published in Environmental Monitoring and Assessment
In 1994, 19 stations were sampled (2 replicates/station) with Young grabs in association with the EMAP-Estuaries Carolian Province Base Monitoring in Florida. A total of 295 unique benthic infauna taxa and 9647 individuals were identified and enumerated. Environmental data (bottom-water quality, sediment grain size, sediment metals, and organics) a...
Recovery of benthic communities at Macquarie Island (sub-Antarctic) following a small oil spill
Published in Marine Biology
Intertidal communities at Macquarie Island (sub-Antarctic) were re-evaluated seven years after a small oil spill resulting from the grounding of the “Nella Dan”, and six years after the first assessment of biological impact. Sampling was conducted to evaluate community structure in three zones of the exposed rocky shore (upper red, kelp, and lower ...
Long-term changes in the benthic communities of the Pomeranian Bay (Southern Baltic Sea)
Published in Helgoländer Meeresuntersuchungen
Long-term changes in the macrofauna of the Pomeranian Bay were studied by comparing survey data from the 1950s, 1980s, and 1990s. The study area has undergone significant eutrophication during the period of investigation. Biomass of filter-feeding bivalves increased significantly. Spatial distribution patterns of several species have changed. Stron...
