(05/21/2013) Drawing from her personal experience as a primate educator and the challenges she saw others facing, Amy Clanin envisioned a network that would advance the field of primate conservation education by addressing three needs of educators: connections, resources, and services. It was this vision that led her to create the Primate Education Network (PEN). PEN is at the forefront of primate conservation education, providing a community and collaboration platform for primate educators.
Sugarcane production impacting local climate in Brazil
(05/01/2013) Intensification of Brazil's sugarcane industry in response to rising demand for sugar-based ethanol could have impacts on the regional climate reports a new study by researchers from Arizona State University, Stanford University and the Carnegie Institution for Science. Following the conversion of cerrado grasslands into sugarcane in Brazil, a recent study in Geophysical Research Letters found local cooling that approached 1 degree Celsius during the growing season and maximum local warming near 1 degree Celsius post-harvest.
Ant communities more segregated in palm oil plantations than rainforest
(03/21/2013) Ants are an important ecological group in both degraded and natural habitats. They interact with many other species and mediate a range of ecological processes. These interactions are often interpreted in the context of ant mosaics, where dominant species form strict territories, keeping other ants out. This segregation between ant species is well-documented in monoculture plantations. Now new research published in Ecography has shown that these changes are driven by the replacement of rainforests with monocultures and not the arrival of non-native species.
Planet organic: achieving sustainable food security and environmental gains
(03/19/2013) The global farmland area certified organic has expanded more than threefold to 37 million hectares since 1999, according to new research conducted by the Worldwatch Institute. The Institute argues that organic farming has the potential to contribute to sustainable food security by improving nutrition intake and sustaining rural livelihoods, while reducing vulnerability to climate change and enhancing biodiversity.
Scientists successfully reintroduce gaur in Indian park
(03/18/2013) Gaur (Bos gaurus gaurus) is one of the large wild ungulates of Asian jungles. It is the tallest living ox, and one of the four heaviest land mammals (elephant, rhino and wild buffalo are the other three), weighing up to 940 kilograms (2,070 pounds) and standing between 1.6 and 1.9 meters (5.2 to 6.2 feet) at the shoulder. Gaur were once distributed throughout the forested tracts of India and South Nepal, east to Vietnam and south to Malaya. Today, however, they are confined to just over a hundred existing, and 27 proposed, Protected Areas in India.
Scientist: releasing invasive birds in Turkey to eat ticks will backfire
(02/04/2013) As Turkey raises and releases thousands of non-native helmeted guineafowl (Numida meleagris) to eat ticks that carry the deadly Crimean-Congo hemorrhagic fever virus, new research suggests guineafowl actually eat few ticks, carry the parasites on their feathers, and further spread the disease.
Recovery of Atlantic Forest depends on land-use histories
(12/10/2012) The intensity of land-use influences the speed of regeneration in tropical rainforests, says new research. Tropical rainforests are a priority for biodiversity conservation; they are hotspots of endemism but also some of the most threatened global habitats. The Atlantic Forest stands out among tropical rainforests, hosting an estimated 8,000 species of endemic plants and more than 650 endemic vertebrates. However, only around 11 percent of these forests now remain.
World has lost half its wetlands
(11/29/2012) Half of the worlds wetlands have been destroyed in just the last 100 years, says a new report. Published by the Economics of Ecosystems and Biodiversity (TEEB), the report found that of the 25 million square kilometers of wetlands that existed in 1900 just 12.8 million square kilometers now remain. The rate of destruction varies geographically with notable loses in East Asia running at 1.6 per cent per year. In places where aquaculture, over-exploitation (e.g. unsustainable harvesting of fish) and storm damage have been severe, the rate of destruction can be as high as 80 percent.
Gaining from rain: precipitation is an indicator of tropical forest biodiversity
(11/12/2012) Policymakers seeking to conserve forests in southern India should focus on those receiving the highest levels of rainfall, according to new research. Scientists from the Center for International Forestry Research (CIFOR) found rainfall to be the most important environmental determinant of species richness in the Anamalai region of the southern Western Ghats.
