In Massachusetts, paralytic shellfish poisoning (PSP) is annually recurrent along the coastline, including within several small embayments on Cape Cod. One such system, the Nauset Marsh System (NMS), supports extensive marshes and a thriving shellfishing industry. Over the last decade, PSP in the NMS ...
Field surveys have reported a global shift in harbour porpoise distribution in European waters during the last 15 years, including a return to the Atlantic coasts of France. In this study, we analyzed genetic polymorphisms at a fragment of the mitochondrial control region (mtDNA CR) and 7 nuclear microsatellite ...
The Antillean manatee (Trichechus manatus manatus), a subspecies of the West Indian manatee, inhabits fresh, brackish, and warm coastal waters distributed along the eastern border of Central America, the northern coast of South America, and throughout the Wider Caribbean Region. Threatened primarily ...
Background The release of oil resulting from the blowout of the Deepwater Horizon (DH) drilling platform was one of the largest in history discharging more than 189 million gallons of oil and subject to widespread application of oil dispersants. This event impacted a wide range of ecological habitats ...
Background Mollusc shells are commonly investigated using high-resolution imaging techniques based on cryo-fixation. Less detailed information is available regarding the light-optical properties. Sea shells of Haliotis pulcherina were embedded for polishing in defined orientations in order to investigate ...
Background Methylmercury (MeHg) is a neurotoxin primarily found in seafood; exposures in reproductive-age women are of concern due to vulnerability of the developing fetus. MeHg is mainly eliminated via an enterohepatic cycle involving the liver and gallbladder. Dysfunction in these organs has been ...
ABSTRACT Subsea trenching operations are routinely performed to provide protection for pipelines, umbilicals and power cables. The increase in offshore wind farm developments and the focus on environmental impact from new regulatory bodies and the public have focused attention on trenching operations. ...
Knowledge of abundance, trends and distribution of cetacean populations is needed to inform marine conservation efforts, ecosystem models and spatial planning. We compiled a geo-spatial database of published data on cetacean abundance from dedicated visual line-transect surveys and encoded >1100 ...
Background Changes in the production of proliferating cell nuclear antigen (PCNA), a 36 kd protein involved in protein synthesis, within intestinal epithelia can provide an early indication of deviations to normal functioning. Inhibition or stimulation of cell proliferation and PCNA can be determined ...
Soybean meal (SBM) is an important protein source in animal feed. However, the levels of SBM inclusion are restricted in some animal species by the presence of antinutritional factors (ANFs), including non-starch polysaccharides (NSPs) and α-galactosides (GOSs). The aim of this study was to reduce the ...
Background Studies conducted with gilthead sea bream (Sparus aurata L.) have determined the maximum dietary replacement of fish meal and oil without compromising growth or product quality. The present study aimed to analyze the effect of the nutritional background on fish health and fish fed plant ...
Fish oil was extracted from the viscera of African Catfish using supercritical carbon dioxide (SC-CO2). A Central Composite Design of Response Surface methodology (RSM) was employed to optimize the SC-CO2 extraction parameters. The oil yield (Y) as response variable was executed against the four independent ...
By the 1950s, pollution had extirpated Atlantic salmon in the river Mersey in northwest England. During the 1970s, an extensive restoration program began and in 2001, an adult salmon was caught ascending the river. Subsequently, a fish trap was installed and additional adults are now routinely sampled. ...
Background Prospective cohort studies in relation to the associations between n-3 polyunsaturated fatty acids (PUFA) and risk of type 2 diabetes (T2D) were inconsistent. Differences in tissue n-3 PUFA compositions in subjects with and without T2D were also inconsistent in both cohort and case-control ...
Background The adoption and maintenance of healthy behaviours is essential in the primary prevention of chronic non-communicable diseases. This study evaluated the effectiveness of a minimal intervention on multiple lifestyle factors such as diet, physical activity, smoking and alcohol, delivered through ...
Abstract eni is committed to operating beyond compliance for biodiversity conservation and the retention of functional ecosystems in all areas and phases of the project lifecycle. In exploration and production (e&p) terms, this means the systematic recognition and integration of biodiversity and ecosystem ...
Abstract In 1996, four offshore oil and gas platforms were removed from the Santa Barbara Channel off the coast of Santa Barbara, California. The four platforms, Heidi, Hope, Hazel, and Hilda, (collectively the 4H platforms) were installed between 1958 and 1965 and provided oil and gas production until ...
Abstract The opening of the Barents Sea for oil and gas exploration and development has been a controversial topic of social debate in Norway, particularly due to environmental and fisheries interests. A zero tolerance regime for oil spills has been introduced in this Northern Region, which means that ...
Abstract Biodiversity is the thermometer of the health of the environment and vital to long term sustainability. Placing biodiversity and environmental capital at risk has proven to be a costly business, but, the burden of proof of environmental damage and liability claims is left with the public. ...
Abstract Marine Bio-Security is a global concern with significant relevance to the off-shore gas and oil production and exploration sector. An avalanche of legislation and regulation is delivering enforceable laws which compel ship owners/operators to adopt prescriptive procedures, protocols and practices ...
