(06/05/2013) When deciding whether or not to clear a patch of rainforest land for development, scientists are often called in to quantify how many different species exist there. But determining the number of rare and threatened species living in a section of jungle isn't easy. If they are very rare, the individual members of the species will be hard to find; if the area being surveyed is along a steep slope it may be difficult to access the area; if there are lots of species to identify, you might need to hire a dream team of biologists—each specialized within a different area of biodiversity—and that can get expensive. However a new study in the Proceedings of the Royal Society Journal by an international group of scientists suggests a more cost-effective and efficient way to rapidly assess local biodiversity.
A Tale of Two Elephants: celebrating the lives and mourning the deaths of Cirrocumulus and Ngampit
(05/07/2013) On March 21st, the organization Save the Elephants posted on their Facebook page that two African elephants had been poached inside a nearby reserve: "Sad news from the north of Kenya. Usually the national reserves are safe havens for elephants, and they know it. But in the last two weeks two of our study animals have been shot inside the Buffalo Springs reserve. First an 18 year-old bull called Ngampit and then, yesterday, 23 year-old female called Cirrocumulus (from the Clouds family)."
Conservation without supervision: Peruvian community group creates and patrols its own protected area
(04/30/2013) When we think of conservation areas, many of us think of iconic National Parks overseen by uniformed government employees or wilderness areas purchased and run from afar by big-donor organizations like The Nature Conservancy, Wildlife Conservation Society, WWF, or Conservation International. But what happens to ecosystems and wildlife in areas where there's a total lack of government presence and no money coming in for its protection? This is the story of one rural Peruvian community that took conservation matters into their own hands, with a little help from a dedicated pair of primate researchers, in order to protect a high biodiversity cloud forest.
Asian bear farming: breaking the cycle of exploitation (warning: graphic images)
(01/31/2013) In the forests of Asia, bears are being captured. These captives will be sent to bear farms, most unregulated and illegal, where they will be kept alive in a small cage, locked away for life. Their bodies will be used as renewable natural resources, from which profit will be made through the extraction of internal organs and fluids. By surgically inserting a permanent catheter into the bears' gall bladders, "farmers" extract several ounces of their bile. In a cycle of exploitation across east Asia, traditional medicine shops receive these daily shipments of bear bile products, while consumers support the industry through the purchase of these products, sustaining a supply-and-demand chain that puts more and more bears in cages as wild populations dwindle.
Living beside a tiger reserve: scientists study compensation for human-wildlife conflict in India
(01/21/2013) During an average year, 87% of households surrounding Kanha Tiger Reserve in Central India report experiencing some kind of conflict with wild animals, according to a new paper in the open-access journal PLOS One. Co-existence with protected, free-roaming wildlife can be a challenge when living at the edge of a tiger reserve. "Local residents most often directly bear the costs of living alongside wildlife and may have limited ability to cope with losses" wrote the authors of the new paper.
Mercury hurts birds and people: what we can learn from studying our feathered friends
(01/07/2013) Birds aren't that different from people. We learn from our parents, just like zebra finches learn songs from their fathers. We are active and noisy during the day, like birds, and we can also be territorial. Also like birds, we try to attract mates through colorful displays and beautiful songs. Birds are sensitive to pollution in their environment just like we are: harmful elements such as mercury wreak similar havoc on human and bird biology alike. Because our species share so many attributes, studying birds illustrates the connections between them and us.
Vanishing corridors: trying to keep big animals on the move across Tanzania
(12/10/2012) One of the biggest challenges for big African wildlife like lions, elephants, and buffalo is movement across native habitat that is increasingly being encroached on by humans. Animals find their movement restricted by roads, fences, and property boundaries which fragment the landscape. Without safe, smart, and well-maintained corridors between designated wildlife areas, animals can get cut off from resources needed for survival and from potential mates (putting genetic health at risk), even while conflicts with humans become more frequent.
Organic farming keeps carbon out of the atmosphere
(11/28/2012) With the worst effects of climate change, we are seeing how pollution hurts both human health and the environment but there is good news: a new study shows that organic farming stores more greenhouse gases in the soil than non-organic farming. By switching to organic methods, many farmers across the globe may be helping to solve the climate crisis at the same time as they improve soil quality and avoid the use of pesticides.
Tanzania weighs new soda ash plant in prime flamingo territory
(11/08/2012) In a choice between flamingoes and a soda ash plant, a new report shows that local residents near Lake Natron, Tanzania prefer flamingoes. This is good news for conservationists as the area is the most important breeding site in the world for lesser flamingos (Phoenicopterus minor). While the report shows agreement between residents and conservation groups that the project isn't worth its cost or risk, the Tanzanian government is not giving up yet.
Appreciating elephant individuality: a new approach to preventing conflicts with humans
(10/09/2012) To prevent conflicts between humans and elephants in developed areas, a new study shows there is much to learn from analyzing Asian elephant behavior at the individual level as opposed to population studies. Researchers have traditionally interpreted elephant behavior at the population level, looking for behavior patterns among elephants of similar ages, group sizes, and genders. Today, field researchers in India are studying elephant behavior at the individual level. Their goal is to appreciate the idiosyncrasies of individual elephants in the hopes of predicting their behavior. Nishant Srinivasaiah, of the Tata Institute of Fundamental Research and lead author of the study, told mongabay.com that it is vital "to get to know our elephants more intimately than ever before and, more importantly, to shift our focus from a population to include its individuals as well."
One extinction leads to another...and another
(08/28/2012) A new study in Biology Letters demonstrates that altering the relationship between a predator and its prey can cause wide-ranging ripple effects through an ecosystem, including unexpected extinctions. Species help each other, directly or indirectly, which scientists refer to as mutualism or commensalism. For example, a species’ success may rely not only upon the survival of its food source, but may also indirectly rely upon the survival of more distantly related species.
