Are Marine Mammals Adapting to Avoid Humans?
January 21, 2015 05:17 PM - Catherine Gill, Care2
Remarkable ocean research shows us that certain whale and seal species are reaching new depths and breaking records by diving so far away from the surface that experts are shocked that they can even survive the pressure. Some animals like the Cuvier’s beaked whales can dive almost 10,000 feet and hold their breath for 138 minutes.
India's Tiger Population on the Rise
January 21, 2015 07:14 AM - WWF Global
India’s tiger population has significantly increased according to the 2014-15 India tiger estimation report released today. Recent years have seen a dramatic rise in numbers– from 1,411 in 2006 to 2,226 in 2014. The increase in the tiger population can be largely attributed to better management and improved protection within tiger reserves and other tiger bearing protected areas. Poaching remains the greatest threat to wild tigers today with tiger parts in high demand throughout Asia.
Planting Milkweed for the Monarch's? Be sure to use the native species!
January 18, 2015 11:04 AM - Kevin Mathews, Care2
Sometimes we do the wrong thing for the right reasons. That appears to be the case for countless Americans hoping to aid the monarch butterfly. Hearing that pesticides have destroyed the milkweed that monarchs rely on for survival, sympathetic animal lovers have attempted to do their part to support the butterflies by growing milkweed in their own gardens. Alas, emerging research suggests that this well-intentioned plan appears to actually be harming the species even further.
Unfortunately, most of the milkweed purchased for this purpose is the “wrong kind.” This kind, known as tropical milkweed, is popular with gardening companies since it continues to bloom longer than the type to which monarch butterflies are accustomed. While monarchs are still more than content to eat this milkweed, that doesn’t make it good for them.
Wild pollinators at risk due to diseased commercial bees
January 16, 2015 09:21 AM - University of Exeter
A new study from the University of Exeter has found that viruses carried by commercial bees can jump to wild pollinator populations with potentially devastating effects. The researchers are calling for new measures to be introduced that will prevent the introduction of diseased pollinators into natural environments. Commercial species of honey bee and bumble bee are typically used to pollinate crops such as tomatoes, sweet peppers and oilseed rape. Fast evolving viruses carried by these managed populations have the potential to decimate wild pollinator species, including bees, hoverflies and butterflies, placing biodiversity and food security at risk.
For sea turtles, there's no place like magnetic home
January 16, 2015 06:16 AM - University of North Carolina at Chapel Hill
Adult sea turtles find their way back to the beaches where they hatched by seeking out unique magnetic signatures along the coast, according to new evidence from the University of North Carolina at Chapel Hill. The findings will be reported in the Cell Press journal Current Biology on Jan. 15.
Did Palm Oil Expansion Play A Role In The Ebola Crisis?
January 15, 2015 04:32 PM - Emmanel K. Urey, MONGABAY.COM
TThe Ebola outbreak in West Africa may have been the result of complex economic and agricultural policies developed by authorities in Guinea and Liberia, according to a new commentary in Environment and Planning A. Looking at the economic activities around villages where Ebola first emerged, the investigators analyzed a shift in land-use activities in Guinea's forested region, particularly an increase in oil palm (Elaeis guineensis) cultivation.
Corals Threatened by Changing Ocean Conditions
January 12, 2015 09:20 AM - Woods Hole Oceanographic Institution
The lowering of the ocean’s pH is making it harder for corals to grow their skeletons and easier for bioeroding organisms to tear them down. Erosion rates increase tenfold in areas where corals are also exposed to high levels of nutrients, according to a study published January 2015 in the journal Geology. As sea level rises, these reefs may have a harder time growing toward the ocean surface, where they get sunlight they need to survive.
First 2 Fugitives from Interpol's Most Wanted Environmental List Nabbed

Launched in October 2014, Infra (which stands for “International Fugitive Round Up and Arrest”) Terra focuses on 139 fugitives altogether wanted by 36 member countries for crimes including illegal fishing, wildlife trafficking, trade and disposal of waste, logging and trading in illicit ivory.
California drought hard on Chinook salmon
January 5, 2015 09:14 AM - Alastair Bland, Yale Environment360
Gushing downpours finally arrived in California last month, when December rains brought some relief to a landscape parched after three years of severe drought.
But the rain came too late for thousands of Chinook salmon that spawned this summer and fall in the northern Central Valley. The Sacramento River, running lower than usual under the scorching sun, warmed into the low 60s — a temperature range that can be lethal to fertilized
Chinook, the largest species of Pacific salmon, need cool waters to reproduce.
Declining Monarch Butterfly Population Warrants Federal Protection
December 31, 2014 09:18 AM - Alicia Graef, Care2
As conservationists continue to worry about the possibility of a world without monarchs, they’ve gotten some hope with an announcement from the U.S. Fish and Wildlife Service (FWS) that federal protection may be warranted for these iconic butterflies. In August, the Center for Biological Diversity, Center for Food Safety, Xerces Society for Invertebrate Conservation and monarch scientist Dr. Lincoln Brower filed a legal petition with the FWS seeking protection for monarchs under the Endangered Species Act.
