The impacts of anthropogenic sound on marine mammals in the Persian Gulf; current status and need for future research
Abstract Sound generating human activities so-called “anthropogenic sound” have increased ambient sound levels considerably in aquatic habitats that are markedly diverse in time and space. Sound generating human activities is now recognized as a potential driver of environmental changes in marine habitats. Iran has 750 km coastline along the Caspian Sea located in the north and around 2250 km ...
متن کاملSex-biases in distribution and resource use at different spatial scales in a migratory shorebird
In migratory species, sexual size dimorphism can mean differing energetic requirements for males and females. Differences in the costs of migration and in the environmental conditions occurring throughout the range may therefore result in sex-biases in distribution and resource use at different spatial scales. In order to identify the scale at which sexual segregation operates, and thus the sca...
متن کاملHarmful Elements in Estuarine and Coastal Systems
Estuaries and coastal zones are dynamic transitional systems which provide many economic and ecological benefits to humans, but also are an ideal habitat for other organisms as well. These areas are becoming contaminated by various anthropogenic activities due to a quick economic growth and urbanization. This chapter explores the sources, chemical speciation, sediment accumulation and removal m...
متن کاملPolychaete Richness and Abundance Enhanced in Anthropogenically Modified Estuaries Despite High Concentrations of Toxic Contaminants
Ecological communities are increasingly exposed to multiple chemical and physical stressors, but distinguishing anthropogenic impacts from other environmental drivers remains challenging. Rarely are multiple stressors investigated in replicated studies over large spatial scales (>1000 kms) or supported with manipulations that are necessary to interpret ecological patterns. We measured the compo...
متن کاملBarnegat Bay-Little Egg Harbor Estuary: Ecosystem Condition and Recommendations
New Jersey’s coastal bays are subject to ongoing multiple anthropogenic impacts from an expanding population in adjoining coastal watersheds. Eutrophication poses the most serious threat to the long-term health and function of the bays, impacting essential habitats (e.g., seagrass and shellfish beds) as well as finfish nursery areas. Nutrient and organic carbon loading in these shallow, lagoon-...
