The shady business of online wildlife trade
April 30, 2013 06:15 AM - Akhila Vijayaraghavan, MONGABAY.COM
The internet is certainly the cornerstone of modern technology and a boon for so much innovation. However, along with all its advantages, there are some serious drawbacks and one of the latest is online smuggling of wildlife. The Indian Express recently reported that India's wildlife police have discovered illegal websites selling live endangered animals, parts and rare plants.
Trees and Smog
April 29, 2013 08:24 AM - Andy Soos, ENN
Trees breathe in CO2 and exhale Oxygen A natural way to refresh the air or so it seems. Smog is a form of pollution. After years of scientific uncertainty and speculation, researchers at the University of North Carolina at Chapel Hill show exactly how trees help create one of society’s predominant environmental and health concerns: air pollution. It has long been known that trees produce and emit isoprene, an abundant molecule in the air known to protect leaves from oxygen damage and temperature fluctuations. However, in 2004, researchers, contrary to popular assumptions, revealed that isoprene was likely involved in the production of particulate matter, tiny particles that can get lodged in lungs, lead to lung cancer and asthma, and damage other tissues, not to mention the environment.
Record Sea Surface Temperatures on Northeast Continental Shelf
April 27, 2013 08:42 AM - ScienceDaily
Sea surface temperatures in the Northeast Shelf Large Marine Ecosystem during 2012 were the highest recorded in 150 years, according to the latest Ecosystem Advisory issued by NOAA's Northeast Fisheries Science Center (NEFSC). These high sea surface temperatures (SSTs) are the latest in a trend of above average temperature seen during the spring and summer seasons, and part of a pattern of elevated temperatures occurring in the Northwest Atlantic, but not seen elsewhere in the ocean basin over the past century.
Ladybugs used as natural pest control inside Mall of America
April 26, 2013 08:28 AM - Allison Winter, ENN
Why is it that we swat away every other bug that happens to land or crawl on us, but when a ladybug finds us, most of us observe it, count its spots, and maybe even blow it away and make a wish? Ladybugs have become popularized in children’s stories and in popular media, so we tend to have a positive perception of these coccinellids being a cute and harmless bug. But another thing that these bugs are known for is being a predator of aphids.
Clownfish helps its anemone host to breathe
April 26, 2013 06:34 AM - Patricia O'Neill, MONGABAY.COM
The sight of a clownfish wriggling through the stinging tentacles of its anemone is a familiar and seemingly well-understood one to most people—the stinging anemone provides a protective home for the clownfish who is immune to such stings, and in turn the clownfish chases away any polyp-eating sunfish eyeing the anemone's tentacles for a meal. But recent research has shown that all that clownfish wriggling significantly helps to oxygenate the anemone at night, when oxygen levels in the water are low.
Women are 'key drivers' in climate change adaptation
April 25, 2013 01:44 PM - Bernard Appiah, SciDevNet
Plans to protect ecosystems and help people adapt to climate change - also known as ecosystem-based adaptation (EBA) - must involve vulnerable groups, including women and communities greatly hit by global warming if they are to succeed, according to scientists who met in Tanzania last month (21-23 March). Scientists and policymakers at the UN-led international workshop on EBA in Dar-es-Salaam, also said that more needed to be done to monitor and evaluate the cost-effectiveness of such adaptation, and to learn from past experiences in order to transfer knowledge into action and policy.
Malaysia may be home to more Asian tapirs than previously thought
April 24, 2013 08:43 AM - Jeremy Hance, MONGABAY.COM
You can't mistake an Asian tapir for anything else: for one thing, it's the only tapir on the continent; for another, it's distinct black-and-white blocky markings distinguishes it from any other tapir (or large mammal) on Earth. But still little is known about the Asian tapir (Tapirus indicus), including the number surviving. However, researchers in Malaysia are working to change that: a new study for the first time estimates population density for the neglected megafauna, while another predicts where populations may still be hiding in peninsular Malaysia, including selectively-logged areas.
Source of Organics and Water Quality
April 23, 2013 04:10 PM - Andy Soos, ENN
It is not unusual that when it rains, it will dissolve surface materials or carny it off as suspended materials into steams and such. Each time it rains, runoff carries an earthy tea steeped from leaf litter, crop residue, soil, and other organic materials into the storm drains and streams that feed Chesapeake Bay or many other bodies of water. Apparently some sources of organics are worse than others. A new study led by researchers at William & Mary's Virginia Institute of Marine Science reveals that land use in the watersheds from which this dissolved organic matter originates has important implications for Bay water quality, with the organic carbon in runoff from urbanized or heavily farmed landscapes more likely to persist as it is carried downstream, thus contributing energy to fuel low-oxygen dead zones in coastal waters.
Kudzu Bugs May Be More Dangerous to Soybean Crops than Previously Thought
April 23, 2013 01:31 PM - Allison Winter, ENN
Many of us know kudzu as the invasive species that grows so rapidly it can destroy valuable forests by preventing trees from getting enough sunlight. Well now we have another "kudzu" species to be worried about — the kudzu bug. Also known as Megacopta cribraria, the kudzu bug is native to India and China, where it is an agricultural pest of beans and other legumes. After first being detected in Georgia in 2009, the kudzu bug has since expanded its territory as far north as Virginia. And according to new research from North Carolina State University, the kudzu bug may be able to expand to other parts of the country.
UN Urges Member Nations Renew Pledges to Respect Earth
April 23, 2013 06:19 AM - United Nations News Service
Top United Nations officials today urged the 193 Member States to renew their pledges to honour and respect Mother Earth marking the day selected by the world body to promote harmony with nature and sustainable development. Today is a "chance to reaffirm our collective responsibility to promote harmony with nature," Secretary-General Ban Ki-moon told the Interactive Dialogue on Harmony with Nature held to mark International Mother Earth Day. Noting this year's theme, Faces of Climate Change, Mr. Ban urged the UN General Assembly "to confront the hard truth that our planet is under threat."
