Robin Brockett, former director of the Wildlife Care Center in Belize, talks about howler monkeys in Belize. She tells “The WildLife” host Laurel Neme how her research into their diet and habits has helped her with rehabilitate howler monkeys captured as pets for release back into the wild.

Howler monkeys are the loudest land animal in the world. They’re known for their loud, guttural, barking howls, which can be heard over three miles away. But did you know that they smell like steeped black tea? Or that they are picky eaters? While howler monkeys in Belize will eat 75 different species of leaves, they’re very particular about the age of the leaves. There are only a few types of leaves they’ll eat year-round. For example, (ficus) fig leaves appear the same all year long but sometimes the howlers will avoid it. That’s because these leaves have a high latex content, and at some point it becomes less palatable and less digestible.

Robin Brockett spent 16 years in Belize first researching howler monkeys in the wild and then spearheading the rehabilitation of confiscated pets back into the wild. Her work led to establishment of the Wildlife Care Center of Belize in 1999, where she served as director for over a decade. Over that time, Robin has nursed and released over 30 howler monkeys back into the wild. Before moving to Belize, Robin Brockett was a primate keeper at Zoo Atlanta for three years where she became involved in behavioral research.  Prior to that, Robin spent three years at the Bronx Zoo in both the bird and mammal departments and also time in zookeeper positions at the Franklin Park Children's Zoo and the New England Science Center.  She’s currently Assistant Bird Curator with the Audubon Zoo in New Orleans.  She still works with the Belize government on issues related to the pet trade. This episode of “The WildLife” aired on The Radiator, WOMM-LP, 105.9 FM in Burlington, Vermont on June 27, 2011.

Doug Emlen, a University of Montana biology professor, reveals the strange and endearing characteristics of dung beetles. He tells “The WildLife” host Laurel Neme about their unique biology and diversity and how the varied shapes of their horns affect their lifestyle. Doug Emlen is a professor of biology at the University of Montana and an expert on the evolution and development of bizarre and extreme morphology of insects. Always interested in animal armaments, he became a dung beetle aficionado after studying a Panamanian dung beetle specializing in howler monkey scat. Since then, he has broadened his research to dung beetles all over the world and has noticed interesting patterns in their weaponry. He has expanded his focus to explore the evolutionary forces that make animal weapons, from dung beetle horns to elk antlers to rhino horns, so diverse. This episode of “The WildLife” aired on The Radiator, WOMM-LP, 105.9 FM in Burlington, Vermont on June 7, 2010 and was rebroadcast on June 13, 2011.

Chris Boget, Executive Director of the Lake Champlain Land Trust talks about common terns and land conservation. He tells “The WildLife” host Laurel Neme how the Common Tern is one of Vermont’s greatest wildlife conservation victories, due to protection of its breeding habitat.

While common terns are the most widespread tern in North America, in many states, including Vermont, they’re threatened or endangered. Habitat loss from either human activities, erosion or even gulls and other critters taking over has led to the concentration of colonies on a smaller number of suitable nesting sites. Consequently, more and more often common terns were nesting at marginal locations where the quality of their habitat was low and the risk of predation – from raccoons, skunks, opossums, gulls and even ants – is high. In Vermont’s Lake Champlain basin, for example, the number of common terns dropped from almost 400 nesting pairs in the 1960s to only 50 in 1988. As a result, in 1989 the Common Tern was placed on the state of Vermont’s endangered species list.

Common Terns are extremely sensitive to disturbance during the breeding season. Adults will attack human intruders in the nesting colonies, often striking them on the head with their bills. The problem is that, the more they have to protect their chicks from intruders, the less time and energy they have to care for their young. The Lake Champlain Land Trust recognized that problem early on and, since 1978, worked to permanently conserve and protect several important Common Tern nesting islands in Lake Champlain. It started by reaching out to the landowners of the few islands with nesting Common Terns and educating them about the value of the birds and the problems they face. The Lake Champlain Land Trust then led the effort to purchase and protect the only possible island habitats for terns. Through the protection of breeding habitat, along with continual monitoring and management efforts of its partners at the Vermont Department of Fish and Wildlife, Green Mountain Audubon Society and Audubon Vermont, the story of the Common Tern is now one of Vermont’s greatest wildlife conservation victories. Their numbers have soared by over 300 percent, from just 50 breeding pairs at the end of the 1980’s to close to 200 today.

Chris Boget, is the Executive Director of the Lake Champlain Land Trust. The mission of the Lake Champlain Land Trust is to save the scenic beauty, natural communities, and recreational amenities of Lake Champlain by permanently preserving significant islands, shoreline areas, and natural communities in the Champlain Region. Chris Boget has more than twenty years of experience in land conservation, including positions with the Vermont Housing and Conservation Board, the Vermont Land Trust, and the Western Pennsylvania Conservancy. Before becoming Executive Director of the Lake Champlain Land Trust, he previously served as their Director of Land Protection and also as Assistant Director. Chris has extensive experience with landowner outreach and education. He received a Master of Science degree in Natural Resource Planning from the University of Vermont and an undergraduate degree in Biology from the College of William and Mary. This episode of “The WildLife” aired on The Radiator, WOMM-LP, 105.9 FM in Burlington, Vermont aired on June 6, 2011.

Siew Te Wong, a Malaysian wildlife biologist and sun bear expert, divulges some interesting characteristics of this rare Southeast Asian bear and how they fit into the ecosystem. He tells “The WildLife” host Laurel Neme how he became one of the first to study sun bears, which are the smallest of the bear species and also the least known. Did you know that sun bears consider beetle larvae one of their tastiest treats? When they eat them, the animals close their eyes and savor the experience, similar to humans relishing the yummiest of chocolates. Siew Te Wong also talks about his adventures researching the species, threats to these rare bears, his rescue efforts, and what people can do to help. For the last 13 years, Wong has been studying and working on the ecological conservation of the sun bear. He is one of the few Malaysian wildlife biologists trained in a western country. He did both his Bachelor of Science and Master of Science at the University of Montana in Missoula, and is continuing for his doctorate degree there. His pioneering studies of sun bear ecology in the Borneo rainforest revealed the elusive life history of the sun bear in the dense jungle. Wong’s research has taken him to the most threatened wildlife habitat on Earth, where field work is exceedingly difficult. While rapid habitat destruction from unsustainable logging practices, the conversion of the sun bear’s habitat into palm oil plantations and uncontrolled poaching activities paint a bleak picture for the future of the sun bear, Wong is determined to help the present situation of sun bears in Southeast Asia. Wong is the CEO of the Bornean Sun Bear Conservation Centre in Sabah, Malaysian Borneo, which he founded in 2008. He was also a fellow of the Flying Elephants Foundation, which awards individuals from a broad range of disciplines in the arts and sciences who have demonstrated singular creativity, passion, integrity and leadership and whose work inspires a reverence for the natural world. Wong is also the former co-chair of the Sun Bear Expert Team, under the IUCN/Species Survival Commission’s Bear Specialist Group and a current member of three IUCN/SSC Specialist Groups. This episode of “The WildLife” originally aired on The Radiator, WOMM-LP, 105.9 FM in Burlington, Vermont on May 17, 2010 and was rebroadcast on May 30, 2011.

Marcela Uhart, Wildlife Conservation Society’s field veterinarian in Patagonia, Argentina, talks about the impact of lead ammunition on wildlife. She reveals to “The WildLife” host Laurel Neme how spent ammunition remains in the environment where it can then be ingested by animals, especially waterfowl. Because they have no teeth, these birds swallow stones and seeds whole to help grind the food in their stomachs.

Argentina is known for its waterfowl hunting, and every year the number of birds killed is huge. However, switching from lead shot is a slow process because hunters have to accept the new ammunition and lead-free alternatives have to be available. In the United States, lead shot to hunt waterfowl in wetlands has been banned since 1991. This regulation came about mostly because bald eagles that preyed on the waterfowl were being poisoned. In addition, there are some more localized bans. For instance, California has banned the use of lead ammunition in the range of the endangered California Condor and Arizona has a voluntary ban. Also, early in 2010, the National Park Service announced a plan to ban lead ammunition and fishing tackle in the parks. Currently, twenty-nine other countries have adopted voluntary or legislative restrictions, with some of the most aggressive regulations having been adopted in Europe.

Dr. Uhart is trying to get similar restrictions in Argentina by studying the impact of lead pellets on waterfowl in Patagonia. Her research on recently-killed ducks has found lead in their blood, which indicates recent exposure, and their bones, which shows lead accumulation over time. Because she is sampling ducks who were healthy enough to fly and be shot, her research probably underestimates the full effects of lead toxicity. Consequently, her next step will be to assess sub-lethal impacts, such as changes in bone density.

Born and raised on a ranch in the Argentine pampas, Marcela Uhart has been a veterinarian with the Wildlife Conservation Society's (WCS) Field Veterinary Program since 1996. She spends much of her time in the field and often collaborates with numerous non-governmental organizations and researchers in Argentina while providing veterinary expertise in wildlife handling and immobilizations, translocations and health monitoring of wildlife populations. She has worked on a variety of species, including sea lions, elephant seals, penguins, small carnivores, caiman and raptors, as well as "agricultural-conflictive" species such as rheas, large rodents and large ungulates, including guanaco and pampas deer. Marcela has helped to introduce new policy measures to benefit wildlife, such as the establishment of a program to control agricultural pesticide use, implemented with the support and endorsement of an Argentine government research agency known as INTA. Marcela also acts as a consultant to field researchers and local conservation groups and has traveled to Bolivia, Chile, Ecuador and other Latin American countries to provide her services. In November 1998, she became one of the founding members of the first Association of Latin American Wildlife Veterinarians. She is also the IUCN’s Wildlife Health Specialist Group (WHSG) coordinator for South America. In this role she hopes to reinforce and revitalize the relationship between wildlife specialists from the developed and developing nations. In fact, since she started at WCS, Marcela has worked tirelessly to address the critical shortage of training opportunities for young veterinarians in Latin America. Professional outreach remains a major focus of her work, as does collaborating with local universities and leading workshops in several Latin American countries. This episode of “The WildLife” aired on The Radiator, WOMM-LP, 105.9 FM in Burlington, Vermont on April 25, 2010.

Carol Foster talks about wildlife filmmaking. She tells “The WildLife” host Laurel Neme, how she and her filmmaker husband, Richard Foster, have constructed a special studio in the jungle of Belize that allows them to film wild behavior that would not otherwise be possible. For instance, they’ve captured a baby cantil viper wriggling the green tip of its tail over its head to attract and capture frogs, and also filmed flower mites hitchhiking in the nostrils of a hummingbird.

Carol and Richard Foster are documentary filmmakers specializing in natural history and the environment. Working out of their jungle studio, they have made films for the major networks including National Geographic and BBC. Both Carol and Richard are highly experienced at bringing to the screen the intricate hidden stories of natural behavior. Both have worked all over the world winning multiple awards for their work. They are currently using their skills to highlight the threats to the environment and nature by humans and climate change--subjects to which they are passionately committed. This episode of “The WildLife” aired on The Radiator, WOMM-LP, 105.9 FM in Burlington, Vermont on April 18, 2011.

Jessica Speart, author of Winged Obsession: The Pursuit of the World's Most Notorious Butterfly Smuggler, discusses illegal trade of rare butterflies. She tells “The WildLife” host Laurel Neme about the real-life characters in her book: Yoshi Kojima, the world’s most wanted butterfly smuggler, and the rookie US Fish and Wildlife agent, Ed Newcomer, who finally brings him down. The trade in rare butterfly species is a lucrative business. While there is much trade that is legal, the illegal butterfly trade could be worth up to $200 million each year. “Butterfly collectors with the financial means will do whatever necessary to obtain the specimens they want,” Speart says. For some, it’s like stamp collecting. For others, it’s the equivalent of collecting a Renoir or Van Gogh.

 

While habitat loss is the most significant threat to butterflies, poaching adds to the stress on these delicate insects – so much so that when criminals target the rare species, extinction becomes a real possibility. Butterfly poachers often pursue the most endangered species, and many prowl national parks where they collect butterfly eggs to raise in a controlled environment. They do this so that they can end up with perfect specimens—and a higher price. Whenever the wings are damaged, the value of the butterfly drops dramatically. As Speart describes in this interview, “The way you get a perfect specimen is to kill them shortly after they’re born.” There’s no other way to make sure its wings remain unused and in perfect condition.

 

Jessica Speart is a freelance journalist specializing in wildlife enforcement issues. She's been published in the New York Times Magazine, OMNI, Travel + Leisure, Audubon, National Wildlife, Mother Jones, Delta's Sky magazine, and many others. She is also the author of ten crime novels featuring the fictional character of US Fish and Wildlife Service special agent Rachel Porter. Rachel has an unwavering devotion to tracking down the enemies of rare and endangered species and, in each book, solves a mystery focused around real world wildlife crimes. Her most recent book, Winged Obsession, is Jessica’s first non-fiction book.  This episode of “The WildLife” aired on The Radiator, WOMM-LP, 105.9 FM in Burlington, Vermont on April 4, 2011.

Anna Bachmann, Director of Conservation for Nature Iraq, and Hana Ahmed Raza, their mammals specialist, discuss wildlife and nature in Iraq. They tell “The WildLife” host Laurel Neme how, after 35 years of wars and sanctions, Iraq’s environment is in dire need of care and attention. In order to rebuild the country’s natural foundation, more information is needed, and Nature Iraq aims to fill some of those gaps.

Nature Iraq is an Iraqi non-governmental organization to protect, restore, and preserve Iraq’s natural environment and the rich cultural heritage that it nourishes. It does this both by improving the capacity of Iraq’s institutions and developing scientific databases of environmental conditions and trends within the country. In this interview, you’ll hear how Iraq’s marshlands, which were destroyed by Saddam Hussein because they were the base of his opposition, have been partially restored and how Nature Iraq is working with the government to create a national park there. You’ll also hear how Nature Iraq is undertaking biological assessments to identify other key areas to protect and working to get Iraq to join the Convention on International Trade in Endangered Species (CITES).

Anna Bachmann is the Director of Conservation for Nature Iraq. Originally from Washington State in the United States, in 2003 Anna traveled to Iraq as a peace activist and subsequently moved to the Middle East to work on environmental issues in Iraq.  She has lived and worked in the region for the past six years, four of those years based in Sulaymaniyah in Iraqi Kurdistan (northern Iraq).  Anna manages the Key Biodiversity Areas Project focused on identifying areas within Iraq that are globally important for their biological diversity.

Hana Ahmed Raza is Nature Iraq’s mammals specialist. Hana was born in Kurdistan in northern Iraq. She graduated from the Biology department of Sulaimaniyah University about a year ago and then started working with Nature Iraq in the field of mammals. She’s the lead author of an upcoming report on "Animal Trade and Hunting in Iraq" and is the focal point of Nature Iraq efforts regarding the Convention on International Trade in Endangered Species (CITES). She also works on broader studies of mammals in Iraq. This episode of “The WildLife” aired on The Radiator, WOMM-LP, 105.9 FM in Burlington, Vermont on March 28, 2011.

Bryan Stuart, curator of amphibians and reptiles at the North Carolina Museum of Natural Sciences, talks about the dark side of the discovery of new species. He tells “The WildLife” host Laurel Neme about his experience following his scientific discovery in Laos of a warty salamander (Paramesotriton laoensis) with striking markings. Shortly after describing the previously unknown species in a scientific paper published in 2002, commercial dealers began collecting the salamanders for sale into the pet trade. Particularly galling to Bryan was the fact that they used his geographic description as a roadmap to find the rare newt. This situation is not unique. It’s also happened with a turtle (Chelodina mccordi) from the small Indonesian island of Roti, which so heavily hunted that today it is nearly extinct in the wild. Similarly, a rare gecko (Goniurosaurus luii) from southeastern China was extirpated from its locality as prices in importing countries soared to highs of $1,500 to $2,000 each. It’s a dual dilemma. On the one hand, publishing new species descriptions may inadvertently facilitate their extinctions for commercially valuable species, yet on the other, the conservation benefits of describing the new species can outweigh this potential risk. Bryan recommends that taxonomists work closely with relevant governmental agencies to coordinate publication of the description with legislation or management plans that thwart overexploitation of the new species. In fact, Bryan and his students have worked tirelessly in this regard and, in August 2008, Laos’ Department of Forestry protected this salamander from commercial trade. Now the remaining question is enforcement. Note: Laurel first met Bryan while researching a wildlife trafficking case for ABC News Nightline that involved the illegal import of hundreds of these rare salamanders that were dried and destined for traditional medicine.

Bryan Stuart is curator of amphibians and reptiles at the North Carolina Museum of Natural Sciences. He received his Bachelor of Science (B.Sc.) in biology from Cornell University, a Master of Science (M.Sc.) in zoology from North Carolina State University, and a Ph.D. in biology from the University of Illinois. He also held a post-doctoral appointment at the Museum of Vertebrate Zoology at the University of California, Berkeley, before returning to Raleigh to join the North Carolina Museum of Natural Sciences in September 2008. His research interests are in the biodiversity, systematics, biogeography and conservation of amphibians and reptiles. Much of his research has focused on amphibians and reptiles of the Old World tropics, especially Southeast Asia, where he has maintained an active field program for the past decade. He has particular interest in using molecular tools to define species boundaries and unravel their evolutionary histories. This episode of “The WildLife” aired on The Radiator, WOMM-LP, 105.9 FM in Burlington, Vermont on March 14, 2011.
