Effects of anthropogenic

آلودگی صوتی به عنوان عامل استرس زا در گونه های جانوری آبزی

Sound travels very efficiently underwater, so the potential area impacted can be thousands of square kilometers or more. Anthropogenic activities such as commercial shipping, recreational activities, drilling, seismic exploration or energy production (hydroelectric power plants), have made underwater noise pollution an increasing and perhaps dominant factor in the aquatic environment. Nowadays,...

The importance of sound effect assessment in the Iranian freshwater endemic fishes

Endemic fishes are part of the genetic resources in aquatic habitats. The Caspian Sea, as the largest lake in the world, has a unique habitat diversity and is of great importance for the countries of the region. Over the recent decades, with the increase in the level of anthropogenic sound, its effects on freshwater and marine fishes have been considered by fisheries managers and stakeholders. ...

Direct and semi-direct radiative effects of anthropogenic aerosols in the Western United States: Seasonal and geographical variations according to regional climate characteristics

The direct and semi-direct radiative effects of anthropogenic aerosols on the radiative transfer and cloud fields in the Western United States (WUS) according to seasonal aerosol optical depth (AOD) and regional climate are examined using a regional climate model (RCM) in conjunction with the aerosol fields from a GEOS-Chem chemicaltransport model (CTM) simulation. The two radiative effects can...

Research Article: Monitoring anthropogenic pollutants in northern coasts of Hormuz Strait using blood indices and thyroid hormone levels in Periophthalmus argentilineatus (Pisces: Gobiidae)

Coastal waters in northern part of Hormuz Strait receive large inputs of anthropogenic pollutants. This study was conducted to determine the effects of environmental contaminants on plasma enzymes, thyroid hormones and biochemical blood parameters of Periophthalmus argentilineatus to monitor marine pollution from northern part of Hormuz strait. For this purpose, a total of 90 specimens were col...

Solar and Wastewater Effects on Zooplankton Communities of the Imandra Lake (Kola Peninsula, Russia), 1990 to 2003

Both heliophysical and anthropogenic (wastewater) effects on zooplankton biomass and abundance of the Imandra Lake (the largest subarctic lake at Kola Peninsula, Russia) were investigated during the 1990 - 2003 period. We used different indexes of solar activity (sunspot numbers and UV- radiation values) as heliophysical factors. Information about UV- radiation values was derived from satellite...
