Currently, the wild population of the greater one-horned rhinoceros (Rhinoceros unicornis) is found in India and Nepal. To manage this transboundary population along the Indo-Nepal border, their habitats and numbers need scientific monitoring. Regular data should be collected on their movement patterns and management, and the data shared across borders with concerned conservation and management agencies to monitor the rhino population and the corridors they use, especially in Suklaphanta–Lagga Bagga, Pilibhit Forest Division, Dudhwa, Katerniaghat and Bardia landscape. Rhinos moving around the Indo-Nepal border in Katerniaghat– Bardia and Lagga Bagga–Suklaphanta should be fixed with radio collars to generate vital information that will assist conservation and management of the greater one-horned rhino along the border, strengthen transboundary planning and conservation for the rhino, besides orienting the police and border security forces in both countries to contribute towards protection of this rhino population moving between the countries. © 2013, International Union for Conservation of Nature and Natural Resources.

The Terai-Duar savanna and grasslands, which once extended along most of the Himalayan foothills, now only remain in a number of protected areas. Within these localities, grassland burning is a major issue, but data on frequency and distribution of fires are limited. Here, we analysed the incidence of active fires, which only occur during the dry season (Nov.-Mar.), within a significant area of Terai grasslands: the Manas National Park (MNP), India. We obtained locations of 781 fires during the 2000-2008 dry seasons, from the Fire Information for Resource Management System (FIRMS) that delivers global MODIS hotspot/fire locations using remote sensing and GIS technologies. Annual number of fires rose significantly from around 20 at the start of the study period to over 90 after 2002, with most (85%) detected between December and January. Over half of the fires occurred in tall grasslands, but fire density was highest in wetland and riverine vegetation, dry at the time. Most burning took place near rivers, roads and the park boundary, suggesting anthropogenic origins. A kernel density map of all recorded fires indicated three heavily burnt areas in the MNP, all within the tall grasslands. Our study demonstrates, despite some technical caveats linked to fire detection technology, which is improving, that remote fire data can be a practical tool in understanding fire concentration and burning temporal patterns in highly vulnerable habitats, useful in guiding management. © Springer Science+Business Media, LLC 2009.

A new species of megophryid frog of the genus Leptolalax is described from the Tamdil wetlands of Mizoram State, north-eastern India. L. tamdil new species, is compared with congeners from India and other parts of south-east Asia. The new species is diagnosable in showing the following combination of characters: SVL 32.3 mm in the only male and 31.8 mm in the only female known; dorsum tuberculate; eyelids with tubercles; tympanum and supratympanic fold distinct; supratympanic fold extending to posterior edge of tympanum; macroglands, including preaxillary, pectoral, femoral and ventrolateral glands present; Finger II > I; toe tips not dilated, bearing dermal fringes; relatively long hind limbs, with heels in contact when limbs are held perpendicular to body; dorsum with dark blotches; flanks with small dark blotches; dark tympanic mask present; venter pale; labial bars present and limbs with dark cross-bars.

The primate monkey species "White Cheeked Macaque," biologically known as "Macaca Leucogenys," has been discovered for the first time in the state of Arunachal Pradesh in India. The wildlife conservation organization Aaranyak confirmed that the discovery was made by a group of biologists and wildlife photographers — Dr. Ranjan Kumar Das, Dr. Dilip Chetry and Udayan Borthakur, along with Binanda Hatibarua, their guide for their bird-watching trip. This group had visited the Anjaw district in March 2015, wherein they had taken a couple of photographs. On examining the images, they discovered this species that is new to India. It differs considerably from all the other possible macaque species like the Arunachal Macaque, Raesus Macaque, Assamese Macaque and the Tibetan Macaque. It took the scientific community a year to finally confirm that the spotted species was indeed that of the rare White Cheeked Macaque. "On the basis of our observations, the photographs and experts' comments, we have come to the conclusion that the macaques we observed and photographed in Anjaw district of Arunachal Pradesh are white-cheeked macaque," said Dr. Dilip Chetry, primatologist and the head of the Primatology Division at the wildlife NGO Aaranyak, who was part of the group that discovered the species. The White Cheeked Macaque itself is a species relatively new to the science world. It was discovered for the very first time quite recently in 2015 through photographs by Dr. Cheng Li and his team. The species was spotted in southeastern Tibet, China. The details of the findings had been published in the American Journal of Primatology dated April 2015. This same primate species discovered in India is absolutely new to the country and the first of its kind — thanks to the amazing discovery made in Arunachal Pradesh. "Until our discovery this primate species was not known to India. Though we found the species last year, we waited till it is confirmed by experts that the primate species is new to India," said Udayan Borthakur, Head of Aaranyak's wildlife genetics. Dr. Ranjan Kumar Das, a renowned bird expert, is absolutely over the moon with his discovery. He is thrilled with the opportune moment that his photographic works can greatly contribute toward the better understanding of this rare species. This discovery is a wonderful revelation and proof of India's rich and diverse fauna, and highlights the need for biodiversity conservation. © 2016 Tech Times, All rights reserved.

A new species of montane toad Duttaphrynus is described from Nagaland state of Northeast India. The new species is diagnosable based on following combination of characters: Absence of preorbital, postorbital and orbitotympanic ridges, elongated and broad parotid gland, first finger longer than second and presence of a mid-dorsal line. The tympanum is hidden under a skin fold (in male) or absent (in female). The species is compared with its congers from India and Indo- China. We propose to consider Duttaphrynus wokhaensis as junior synonym of Duttaphrynus melanostictus. Copyright © 2013 Magnolia Press. Source
