Climate change signals a whale of a shift in feeding patterns
November 26, 2013 09:08 AM - Rebecca Kessler, Yale 360
Every summer and fall, endangered North Atlantic right whales congregate in the Bay of Fundy between Nova Scotia and New Brunswick to gorge on zooplankton. Researchers have documented the annual feast since 1980, and well over 100 whales typically attend, a significant portion of the entire species. Only this year, they didn't. Just a dozen right whales trickled in—a record low in the New England Aquarium's 34-year-old monitoring program. And that comes on the heels of two other low-turnout years, 2010 and 2012.
"Location, location, location" on the wild side
November 25, 2013 04:16 PM - Robin Blackstone, ENN
The old real estate adage "location, location, location" is still the most important factor in purchasing property but the term "location" is bringing with it a different perspective today than it did years ago. While property sales have boasted bonus attributes such as proximately to shops, bus routes, beach front and features such as media rooms, offices and central air conditioning and "other amenities" little has been said about wildlife-friendly gardens.
80,000 acres swallowed up
November 25, 2013 02:58 PM - Robin Blackstone, ENN
The United States has lost approximately 80,000 acres of coastal wetlands between 2004 and 2009 according to the U.S. Fish and Wildlife Service and the National Oceanic and Atmospheric Administration (NOAA). Much of this loss is blamed on development and has occurred in freshwater regions. Additionally, more than 70% of the loss is from the Gulf of Mexico. According to the EPA wetland loss in the eastern U.S. is happening at a rate double that of what is being restored.

Soaring silently above the landscape, owls search out their prey utilizing acoustic stealth. University of Cambridge, England researchers led by Dr. Justin Jaworski are studying the owl’s wing structure and mechanics to better understand how it mitigates noise to apply that information conventional aircraft design.
Arctic at risk from invasive species
November 25, 2013 09:31 AM - Christopher Ware, Ecologist
As the Arctic ice melts, new shipping routes are opening up for tourism, mining and other commercial purposes, cutting journey times and fuel costs. And as Christopher Ware reports, a new danger arises - invasive alien species disrupting fragile Arctic ecosystems...
Pre-industrial Methane Emissions Triggered by Natural and Anthropogenic Causes
November 25, 2013 09:19 AM - Allison Winter, ENN
The climate change debate has been going back and forth between skeptics and believers for the last couple of years. While carbon dioxide is usually the greenhouse gas that gets the most attention, methane is considered another powerful greenhouse gas that can be emitted both naturally as well as human-induced. A new study suggests the increase in methane emissions since the industrial revolution cannot be blamed on anthropogenic sources alone.
Brazil Deforestation Up 28%
November 21, 2013 04:54 PM - Editor, The Ecologist
After a significant drop in the last several years, the annual deforestation rates in Brazil raised 28% for the period August 2012-July 2013, according to INPE, the Brazilian Spatial Institute. The total area deforested in 2012-2013 is 5,843 km2 - a trend led by the states of Mato Grosso, Roraima, Maranhão, and Pará. The area cleared in Mato Grosso rose 52% from 757 km2 in 2012 to 1,149. The area cleared in Pará rose 37% from 1,741 km2 to 2,379 km. For Roraima deforestation increased 49% from 124 km2 to 185 km2. Maranhão registered 269 km2 cleared in 2012 and 382 km2 in 2013, an increase of 42%...
Deadly Disease Causes Extinction of Darwin's Frog
November 21, 2013 11:24 AM - Allison Winter, ENN
Discovered by Charles Darwin in 1834, Rhinoderma darwinii (better known as Darwin's frogs) have been declared extinct after a killer disease is thought to have wiped out entire populations across Chile and Argentina. According to scientists from the Zoological Society of London (ZSL) and Universidad Andrés Bello (UNAB), Chile, chytridiomycosis is the main reason for this amphibian extinction.
Modern Mobile Equipment Captures Thundersnow in Action
November 20, 2013 11:49 AM - Allison Winter, ENN
Thundersnow, also known as a winter thunderstorm, is an unusual kind of thunderstorm where snow falls instead of rain. The interaction of clouds and ice pellets inside these storms generates a charge, resulting in lightning and thunder. While these events are fairly rare around the globe, they are most common with lake-effect snow, especially near the Great Lakes. In order to capture these rare thundersnows in action, the National Science Foundation (NSF) will send out the Doppler-on-Wheels (DOW) and the King Air, a University of Wyoming instrumented aircraft.
Quick tsunami sensors tested in Mediterranean
November 20, 2013 08:58 AM - Giovanni Sabato, SciDevNet
A new alert system could improve tsunami warnings in the Mediterranean, but most countries bordering the sea still lack evacuation plans, scientists have said ahead of a meeting of 20 countries in Italy this week (19-21 November). The tenth session of the Intergovernmental Coordination Group for the North-Eastern Atlantic, Mediterranean and connected seas, Tsunami Warning and Mitigation System (NEAMTWS) will discuss establishing new national tsunami warning centres. It will also work towards organising the next tsunami exercise, a simulation of tsunami alerts following several different kinds of earthquakes, to evaluate the communication and response mechanisms throughout the NEATWS network.
