  2012 MAY 18 - (VerticalNews.com) -- According to the authors of recent research from Toledo, Spain, "Current climate change exacerbates the environmental restrictions on temperate species inhabiting low latitude edges of their geographical ranges. We examined how temperature variations due to current and future climate change are likely to affect populations persistence of stream-dwelling brown trout Salmo trutta at the vulnerable southern periphery of its range. ...read more

  2012 MAY 18 - (VerticalNews.com) -- "Aquatic biodiversity faces increasing threats from climate change, escalating exploitation of water and land use intensification. Loss of vegetation in catchments (= watersheds) has been identified as a substantial problem for many river basins, and there is an urgent need to better understand how climate change may interact with changes in catchment vegetation to influence the ecological condition of freshwater ecosystems," scientists in Heidelberg, Australia report ...read more

  2012 MAY 18 - (VerticalNews.com) -- "Climate change is conceptually referred to as a modification to the average of climate variables and their natural variability, due to both natural and anthropogenic driving forces, such as greenhouse gas emissions. Climate change potentially impacts rainfall, temperature, and air humidity, which have relationship with plant evapotranspiration and consequently to irrigation water needs (IWN)," investigators in Fortaleza, Brazil report ...read more
