Herons nesting in the wetlands of southeast Chicago are still being exposed to chemicals banned in the U.S. in the 1970s, a research team reports. The chemicals do not appear to be affecting the birds’ reproductive success, however.

Thailand’s Western Forest Complex – a 6,900 square mile (18,000 square kilometers) network of parks and wildlife reserves – can potentially support some 2,000 tigers, making it one of the world’s strongholds for these emblematic big cats, according to a new study by Thailand’s Department of National Park, Wildlife, and Plant Conservation and the New York-based Wildlife Conservation Society.

Scientists at Northern Arizona University and the National Center for Ecological Analysis and Synthesis have developed a model that uses circuit theory to predict gene flow across landscapes.

Researchers at the Wildlife Conservation Society and other institutions declare that improvements in management of existing protected areas in South Asia could double the number of tigers currently existing in the region.

To experience firsthand the complex problems that influence biodiversity, Birgitta Kajler, an educator of future wildlife conservationists in Sweden, spends a lot of her time traveling the world.

Tradable permits are all the rage in environmental policy. They are already used internationally to reduce carbon emissions and improve air quality. A group of economists and ecologists from the UK, the Netherlands and Germany, are working together to find out whether such schemes could work for wildlife too.

At a time when encroaching human development in former wildlife areas has compressed African elephants into ever smaller home ranges and increased levels of human-elephant conflict, a study in the October 9th issue of Current Biology, a publication of Cell Press, suggests that strategically placed beehives might offer a low-tech elephant deterrent and conservation measure.

Andrea Fowler, David Lodge, and Jennifer Hsia (University of Notre Dame) examined the efficacy of the Lacey Act in their research communication, “Failure of the Lacey Act to protect US ecosystems against animal invasions.”

For years, wildlife managers and biologists in Africa have known that large mammals were disappearing outside reserves. There are historical accounts describing impressive populations of large mammals resident or migrating through areas that are nowadays devoid of anything bigger than passerines and rodents and that are now perhaps a patchwork of small scale land holdings instead of natural vegetation.

One of Australia’s greatest conservation challenges in protecting the Great Barrier Reef and other natural assets is staying one jump ahead of both the movement of protected species and the emergence of new and unforeseen threats.

American bald eagle is taken off the endangered species list. Now the birds don’t need to be protected by Endangered Species Act anymore.

Loss of wetlands and industry pollution result in climate change that makes difficult conditions for American bird species to survive.
