Cloud Forests and Biodiversity
Tropical cloud forests are situated in mountains and are characterized by the frequent presence of low-level clouds. Scientists have always regarded them as having high biodiversity, but a study published recently in mongabay.com's open access journal, Tropical Conservation Science adds a new dimension: it found cloud forests contain a significant and surprising array of tree and bromeliad species, even when they are relatively small. >> Read the Full Article
For healthy oceans, end illegal fishing: WWF
Last week, Secretary of State John Kerry brought together some of the world's leading thinkers to chart a path for securing the future of our planetâ€™s oceans and the communities and economies they support. Leaders from more than 80 countries delved into the most pressing issues facing our oceans, including marine pollution, climate change and unsustainable fisheries. >> Read the Full Article
Study links pesticides and pregnancies with increased risk of autism
Pregnant women who lived in close proximity to fields and farms where chemical pesticides were applied experienced a two-thirds increased risk of having a child with autism spectrum disorder or other developmental delay, according to a new study. The research discovered the associations were even stronger when the exposures occurred during the second and third trimesters of the women's pregnancies. >> Read the Full Article
New study challenges theory that emperor penguins return to same area each year
Philopatry is the tendency of an organism to stay in, or return to its home area. Many animal species are considered philopatric because they often return to their birthplace year after year to breed. Revisiting the same site is advantageous because nests and courtship areas have already been established while competition from other animals is largely non-existent due to territoriality. Researchers have long thought that emperor penguins were a prime example of this phenomenon, however a new study shows that this species may be adapting to changing environments and may not necessarily be faithful to previous nesting locations. >> Read the Full Article
New study shows link between bald eagle deaths and lead ammunition
Endangered California condors have been the poster birds for calls to get lead ammunition out of our environment, but they might have to make some room for our nation's most iconic raptors thanks to a new study showing how lead ammunition is also harming bald eagles. It might be illegal to hunt bald eagles, but a study conducted by the U.S. Fish and Wildlife Service investigating the link between lead ammunition and bald eagle deaths in the Upper Mississippi River U.S. Fish and Wildlife Refuge. >> Read the Full Article
Over $1 Billion Pledged to Project Marine Habitats
'Our Ocean' 2014 brought together leaders from business, government and academic institutions, and NGOs from over 80 countries to discuss how economic development and ocean conservation can be reconciled. The oceans are extremely important for humans, generating more than 50 percent of the oxygen we breathe, absorbing excess carbon dioxide, and providing a source of food and income for millions of people worldwide. >> Read the Full Article
"Tuning" the silk: How spiders use vibrations to learn about their prey, mates, and web
The fine craftsmanship of a spider's web helps these eight-legged arachnids catch their prey. But these silk-threaded designs can tell a spider a lot more than what they will be having for dinner. The spider that sits in the middle of its web monitors the silk threads for vibrations. And according to a new discovery by researchers at the Universities of Oxford, Strathclyde, and Sheffield the frequencies of these vibrations carry specific information about the prey, mates, and even the structural integrity of the web. >> Read the Full Article
President Obama addresses seafood fraud and illegal fishing
This morning, President Barack Obama announced an initiative to tackle seafood fraud and illegal fishing in the United States. His announcement coincides with the Global "Our Ocean" conference convened by U.S. Secretary of State John Kerry. In President Obama's announcement, he referenced the negative financial repercussions of overfishing as one of the key reasons for the initiative. >> Read the Full Article
Antarctic Icebergs battering shorelines
The Antarctic shore is a place of huge contrasts, as quiet, dark, and frozen winters give way to bright, clear waters, thick with algae and peppered with drifting icebergs in summer. But as the planet has warmed in the last two decades, massive losses of sea ice in winter have left icebergs free to roam for most of the year. As a result, say researchers reporting in the Cell Press journal Current Biology on June 16, boulders on the shallow seabed -- once encrusted with a rich assemblage of species in intense competition for limited space -- now mostly support a single species. The climate-linked increase in iceberg activity has left all other species so rare as to be almost irrelevant. "The Antarctic Peninsula can be considered an early warning system -- like a canary in a coal mine," says David Barnes of the British Antarctic Survey. "Physical changes there are amongst the most extreme and the biology considered quite sensitive, so it was always likely to be a good place to observe impacts of climate change -- but impacts elsewhere are likely to be not too far behind. A lot of the planet depends on the near-shore environment, not least for food; what happens there to make it less stable is important." >> Read the Full Article
How ocean acidification is affecting marine life
A new study by researchers at the University of Bristol and Plymouth Marine Laboratory has shed light on how different species of marine organisms are reacting to ocean acidification. Since the Industrial Revolution, nearly 30 per cent of all the carbon dioxide produced by manmade emissions has been absorbed by the ocean, causing a drop in pH of ocean surface waters: ocean acidification. >> Read the Full Article
