Associated Press: University of Maine researchers are studying the impact of hemlock tree die-offs on the state's freshwater forests. UMaine stream ecology assistant professor Hamish Greig and Climate Change Institute Jacquelyn Gill are leading the researchers as they study past and present declines of the trees. The trees are threatened by pests that have also decimated the species in the southeastern states. Gill says warmer temperatures have allowed the hemlock woolly adelgid to gain a foothold in Maine.

Associated Press: Marine biologists worked Monday to determine whether a recent Southern California heat wave, lack of oxygen in the water or other factors might have caused the death of thousands of fish along the coastal waters of Marina del Rey. California Fish and Wildlife workers continued to remove the dead anchovies and stingrays that created a silvery blanket on the water's surface and a pungent smell that set off a feeding frenzy among harbor seals, pelicans and seagulls. An octopus was also found among...

That means keeping the pollinators away from the poisoned trees that caused the deaths. And for some activists, it also means pushing for new rules and policies to curb use of neonicotinoid insecticides. The tragedy started a week and a half ago when a landscaping company sprayed Safari neonic insecticide...

2013-06-16 18:25:00| Climate Ark Climate Change & Global Warming Newsfeed
Tampa Bay Times: The Indian River Lagoon on Florida's east coast has long been known as the most diverse ecosystem in North America. Its 156 miles of water boasts more than 600 species of fish and more than 300 kinds of birds. The lagoon is not just an ecological treasure. To the towns along its edge -- Titusville, Cocoa, Melbourne, Vero Beach and Stuart, among others -- it accounts for hundreds of millions in revenue from angling, boating, bird-watching, tourism and other waterfront activities. But these days...

Rate of tree die-off in Amazon higher than conventionally believed

Mongabay: The rate of tree mortality in the Amazon rainforest due to storm damage and drought is 9-17 percent higher than conventionally believed, reports a study published in the Proceedings of the National Academy of Sciences (PNAS). Comparing Landsat satellite images with on-the-ground observations, researchers from the Lawrence Berkeley National Laboratory, INPA, Tulane University, and other institutions found that roughly half a million dead trees across a 1000-square-mile plot of Brazilian rainforest...
