Mekong dams threaten rare giant fish
July 29, 2010 09:21 AM - World Wildlife Fund, WWF

Wild populations of the iconic Mekong giant catfish will be driven to extinction if hydropower dams planned for the Mekong River go ahead, says a new report by WWF. Current scientific information suggests the Mekong giant catfish migrate from the Tonle Sap Lake in Cambodia up the Mekong River to spawn in northern Thailand and Laos. Any dam built on the lower Mekong River mainstream will block this migration route.

Big Brains, Small Brains
July 19, 2010 04:15 PM - Andy Soos, ENN

Why is there a brain and why are some larger and others smaller? What advantage is there to having them has been often argued. Recently published in the Journal of Evolutionary Biology, new studies reveal that "species which have developed large brains live for longer than those with small brains, as the protective brain theory suggests, and therefore, can reproduce more times".

Trees a 'low-cost' solution to air pollution and biodiversity loss in cities

Editor, Ecologist
Native woods and trees in urban areas, including gardens, provide haven for wildlife, reduce air pollution, surface run-off and flooding Reversing the declining numbers of native trees and woods in cities would provide numerous benefits at 'relatively little cost', says a report from the Woodland Trust. As well as access to green space, the report, 'Greening the Concrete Jungle', says trees provide a wide range of free ecosystem services including reducing the risk of surface water flooding and improving air quality that could save millions in flood defence and healthcare costs.

COMMENTARY

Commemorative Robert Bateman Print Helps Combat Nature Deficit Disorder

Roger Greenway, ENN
ENN is a media sponsor of the Robert Bateman "Get to Know" contest. Now, the National Forest Foundation is offering Robert Bateman's new print Family Hike to benefit More Kids in the Woods which provides grants to nonprofits that take kids beyond four walls and into their backyard — be it a county park, National Forest, or other wild place — an effort to ensure that today’s children know what it is to grow in the open air. It's summertime, which for many of us means that it's time to lace up our boots and head for the hills. Or perhaps it's time to roll out the tent, pack up the marshmallows, and re-acquaint ourselves with a favorite campsite. Unfortunately, too many children today don’t have the opportunity for these outdoor adventures. You’ve heard of Nature Deficit Disorder, Electronic Overload, and any number of other catchy phrases. Call it what you will, the message is the same: kids don’t spend enough time outdoors.
