© The Ecological Society of America www.frontiersinecology.org A light at night is globally widespread (Cinzano et al. 2001), rapidly expanding in spatial extent (Hölker et al. 2010), and shifting in its spectral characteristics (Davies et al. 2013a). Increasing concern over these trends has recently fuelled a surge in research toward understanding the ecological impacts of artificial light pol...

BACKGROUND AND OBJECTIVES: The classification of marine animals as protected species makes data and information on them to be very important. Therefore, this led to the need to retrieve and understand the data on the event counts for stranded marine animals based on location emergence, number of individuals, behavior, and threats to their presence. Whales are g...

Discharges of metal oxide nanoparticles into aquatic environments are increasing with their use in society, thereby increasing exposure risk for aquatic organisms. Separating the impacts of nanoparticle from dissolved metal pollution is critical for assessing the environmental risks of the rapidly growing nanomaterial industry, especially in terms of ecosystem effects. Metal oxides negatively a...

Plastic production has increased dramatically worldwide over the last 60 years and it is nowadays recognized as a serious threat to the marine environment. Plastic pollution is ubiquitous, but quantitative estimates on the global abundance and weight of floating plastics are still limited, particularly for the Southern Hemisphere and the more remote regions. Some large-scale convergence zones o...

Oil pollution is in the forefront ofpublic attention because of the recent series of oil spills from tankers such as the Argo Merchant. Oil spillage frequently destroys the marine flora and fauna; the most striking single effect is the oiling of large numbers of marine birds. For example, as many as 30,000 birds died after the grounding of the Torrey Canyon at Seven Stones Reef, Great Britain i...

Abstract: Marine macro-algae are very important biological indicators of the ecological status of the marine environment because they are first to react to the pollution entering the sea including nutrients which determine the trophy of the ambient of the environment. The aim of this paper is to evaluate the present trophic level and the health status of the sampling stations according to the E...

Pollution in the natural aquatic environment is erratic and manifests as temporary increments of chemical concentrations, pulses. Traditional ecotoxicological testing does not consider intermittent exposures and does not consider the post-exposure period even though latent effects may occur. Sugar kelp (Saccharina latissima, L.) was exposed to pulses of seven antifouling compounds with differen...

Different types of water bodies, including lakes, streams, and coastal marine waters, are often susceptible to fecal contamination from a range of point and nonpoint sources, and have been evaluated using fecal indicator microorganisms. The most commonly used fecal indicator is Escherichia coli, but traditional cultivation methods do not allow discrimination of the source of pollution. The use ...
