New insights into global ocean microbe-virus interactions, drivers of Earth's ecosystems
2015-05-21 12:00:00| LifeSciencesWorld
[NEWS] Hidden among Earth's vast oceans are some of the tiniest and most vital organisms to the health of delicate ecosystems. Ocean microbes produce half of the oxygen we breathe, and are important drivers in chemical reactions and energy transfers that fuel critical ecological processes. Much like other organisms, marine microbes are susceptible to viral infections that can alter their metabolic output, or even kill them. For example, certain ocean viruses invade algae and tak…

Climate change threatens world iconic ecosystems
2015-03-22 08:42:00| Climate Ark Climate Change & Global Warming Newsfeed
Zee News: Without better local management, world's most iconic ecosystems are at risk of collapse under climate change, warn researchers. Protecting places of global environmental importance such as the Great Barrier Reef and the Amazon rainforest from climate change will require reducing pressures like over-fishing, fertiliser pollution and land clearing, they said. Writing in the journal Science, an international team of researchers warned that localised issues, such as declining water quality from...

Shrinking Forest Habitats Impact Global Ecosystems
2015-03-21 18:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: It's no secret that human activity is transforming our world. For example, increasing development for agriculture or new communities is shrinking forest habitats, and new research shows that this is having a significant impact on global ecosystems. According to findings published in the journal Science Advances, 70 percent of existing forest lands are within a half-mile of the forest edge, where encroaching urban, suburban or agricultural influences can cause any number of harmful effects - such...

World's Most Iconic Ecosystems May Collapse Under Climate Change
2015-03-21 02:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Researchers warn that without better local management, some of the world's most iconic ecosystems may collapse under climate change. It is well known that corals in the Great Barrier Reef, for example, are diminishing due to ocean acidification, and that the Amazon rainforest has been suffering from drought over the last decade. But in order to combat such climate change-related threats, we need to reduce the other pressures they face - for example, overfishing, fertilizer pollution or land clearing....
