Human Impacts On Top Ocean Predators Along US West Coast Mapped
2013-10-28 08:20:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: The California Current System along the U.S. west coast is among the richest ecosystems in the world, driven by nutrient input from coastal upwelling and supporting a great diversity of marine life. Like coastal regions in general, it is also heavily impacted by human activities. A new study led by scientists at the University of California, Santa Cruz, reveals areas along the west coast where human impacts are highest on marine predators such as whales, seals, seabirds, and turtles. The study,...
Crop-damaging pests spreading due to climate change; faster than their predators

GlobalPost: Pests that eat and damage crops are spreading both further north and south due to climate change, according to a new study. Researchers in Britain say that beetles, bacteria, funghi, worms, moths and other pests are moving at a rate of 16 miles per decade - that's faster than theoretical predictions in 2011 that found similar results. Both global warming and human transport are helping them spread, say scientists. The study looked at over 600 pests around the world and found that they were moving...

Conserving top predators results in less CO2 in the air

Mongabay: What does a wolf in Yellowstone National Park have in common with an ambush spider on a meadow in Connecticut? Both are predators and thus eat herbivores, such as elk (in the case of wolves) and grasshoppers (in the case of spiders). Elk and grasshoppers also have more in common than you probably imagine: they both consume large quantities of plant matter. While scientists have long-known that predators lead to carbon storage by reducing herbivore populations, a new study reveals a novel way in which...
Wiping out top predators messes up the climate

New Scientist: FLATTENED forests and melted permafrost boost greenhouse gas emissions - and now it seems the plight of nature's top predators, too, will speed up the planet's lurch towards a hotter climate. Mass extinctions of the big beasts of the jungles, grasslands and oceans could already be adding to emissions, according to a new study based on fieldwork in aquatic ecosystems. Equally, saving such species could keep greenhouse gases locked away, raising the possibility of conservationists claiming carbon...
