Using camera traps survey techniques, researchers from WCS’s Myanmar Program have combed the 3,250-square-kilometer core area (approx. 1,250 square miles) of the Hukaung tiger reserve, the world’ largest protected area for tigers, for evidence of the big cats and other wildlife. The recently published data were gathered between December 2002 and May 2004.
During that time, the researchers photographed six individual tigers some 21 times in the reserve, and this has allowed the first ever scientific estimate of abundance for these big cats in northern Myanmar.
“We know there are tigers here, but previously we were not able to put some numbers to the population,” said Wildlife Conservation Society researcher, U. Than Myint, co-author for an article in the July edition of the journal Population Ecology which details efforts to measure tiger numbers in Myanmar’s Hukaung Tiger Reserve. “We have collected the first real data needed to determine how many tigers are here. From the analyses of this data, it is estimated that there are at least seven and potentially up to 70 tigers living in the core area.
Estimating numbers of prey animals such as gaur and sambar may give an indication of how many tigers can be supported over this vast habitat, but any further ecological monitoring will likely need to be done at the same time as efforts are increased to protect tigers and their key prey species from illegal hunting and trade.”
Researchers have also confirmed the continued existence of 18 smaller carnivores in a variety of habitats across Myanmar, according to another study by WCS’s Myanmar Program that appeared in the April edition of the journal Small Carnivore Conservation. Data on small carnivores gathered from camera-trap surveys in wild areas across the country were supplemented by the examination of animal remains found in villages and markets. The researchers found that some species such as the yellow-throated marten and the common palm civet are common throughout their country range. Red pandas were not photographed but identified as present in Hkakaborazi National Park and other areas. Other species that were not detected at all in the surveys, such as four species of otter, could be in need of protection.
“One of the most important needs for the conservation of these wild places is to get a better understanding of the status of these predators,” said WCS researcher U. Than Zaw, lead author of the small carnivore study. “So far, we’ve determined that otter populations have been decimated, mostly through a combination of hunting for their pelts and for medicines, and through loss and disturbance of their aquatic habitats. Otters require immediate conservation management. As for the other species, continued monitoring is needed to better ascertain the ecological needs of Myanmar’s wildlife.”
Funding for the research efforts were provided by the U.S. Fish and Wildlife Service’s Rhino and Tiger Conservation Fund, the National Fish and Wildlife Foundation’s Save the Tiger Fund, and the Liz Claiborne Art Ortenberg Foundation.
The Wildlife Conservation Society saves wildlife and wild places worldwide. We do so through science, global conservation, education and the management of the world's largest system of urban wildlife parks, led by the flagship Bronx Zoo. Together these activities change attitudes towards nature and help people imagine wildlife and humans living in harmony. WCS is committed to this mission because it is essential to the integrity of life on Earth.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
