Yale Environment 360: Forests, tundras, and alpine areas are some of the worlds most at-risk ecosystems to climate change, according to a new map published in the journal Nature. The study, led by scientists at the University of Bergen in Norway, used satellite data collected from 2000 to 2013 to examine how sensitive plants were to changes in air temperature, water availability, and cloud cover, down to a two-square-mile scale. The scientists used the results to create the Vegetation Sensitivity Indexa visual guide...

Mongabay: The Amazons freshwater ecosystems are at risk because current policy and existing protected areas fail to protect the connectivity of the water cycle, scientists warn. The new study, published in Global Change Biology, examines the factors degrading the Amazon basins hydrological connectivity: the movement of water and with it the life-giving matter, nutrients and organisms it carries between the vast systems headwaters and the Atlantic Ocean, between the rivers and the forest, and the earth...

A/C could endanger health, food security, ecosystems

Jerusalem Post: We pay less attention to the seasonal ticking partly because we live in an artificial environment of constant summers with steady temperatures and available lighting. Living under constant and stable temperatures throughout the year due to air conditioning, heating and artificial lighting at night is liable to harm our health, food security and ecological systems, according to a international study by 63 researchers from 24 universities, including Tel Aviv University. The study was published...

Humans are changing ocean ecosystems in fundamental and surprising ways
2015-10-09 07:40:00| Climate Ark Climate Change & Global Warming Newsfeed
PhysOrg: Humans are changing the 'landscape of fear' in oceans in many more ways that previously thought, and the effects of these changes can ripple through ocean ecosystems in a wide variety of surprising ways, research by Dr Elizabeth Madin from the Department of Biological Sciences and colleagues from Simon Fraser University, Canada and the University of California and Florida International University in the United States has found. Where predators, such as sharks and other big animals, have largely...
