What are the consequences of rapid global change for the behaviour and ecology of wild species? Answering this very broad question is a challenging but important task. One relatively manageable question under this broad umbrella is how the timing of biological events (i.e., phenology) is changing as the earth’s climate
changes. In this article, we describe a new programme aimed at assessing the timing of migration of birds that winter in the Indian Subcontinent and monitoring changes in this timing over the long term. MigrantWatch is a volunteer-based programme in which participants record the arrival, presence and departure of migrant species across India. We also outline the goals, structure, and open-access philosophy of the programme, and illustrate its potential by briefly describing information collected on the arrival patterns of winter migrants in the second half of 2007.

The discovery of the leaf deer Muntiacus putaoensis in northern Myanmar has added to the growing list of large mammals recently discovered in remote, unex- plored parts of south and south-east Asia. Its subsequent discovery in eastern Arunachal Pradesh, India, based on morphometric analyses of two skulls collected from local hunters, doubled the size of its known east-west range, which is significant for a newly-discovered and poorly understood species. However, ambiguity remained regarding several other partial skulls and dried skin samples collected during subsequent surveys. The sympatric occurrence of the Indian muntjac Muntiacus muntjak further complicates species identification based primarily on morphometry. In this paper, we develop molecular genetic analyses that can unambiguously identify muntjac species. Further, we test and apply our methods to unknown skin samples to confirm the occurrence of the leaf deer in Arunachal Pradesh. Finally, we use our samples and genetic data from three mitochondrial markers to establish phylogenetic affinities between these samples and other extant members of the Muntiacus genus. Our approach, which combines the use of specific primers and phylogenetic analyses, is generally applicable towards the detection of cryptic biodiversity in unexplored and species-rich areas like north-east India.

This Alphabet book was produced mainly for Lisu children at several Kindergarten schools in remote villages of eastern Arunachal Pradesh near the Namdapha National Park that are supported by Katha, New Delhi. The Katha-Lisu schools set up in 2003 are managed by the Nature Conservation Foundation (as part of its community-based conservation program) and Lisu villagers. Lisu youth are employed as school teachers. We felt the need for making a book that uses words from nature (animals, plants) and everyday objects that rural children are familiar with and would more readily identify with than those that are usually used in such books. We have tried our best to do this, although we faced difficulties with some letters!

In addition to the threats of habitat loss and degradation, adult males of the Asian elephant Elephas maximus also face greater threats from ivory poaching and conflict with humans. To understand the impact of these threats, conservationists need robust estimates of abundance and vital rates specifically for the adult male segment of elephant populations. By integrating the identification of individual male elephants in a population from distinct morphology and natural markings, with modern capture–recapture (CR) sampling designs, it is possible to estimate various demographic parameters that are otherwise difficult to obtain from this long-lived and wide-ranging megaherbivore. In this study, we developed systema- tic individual identification protocols and integrated them into CR sampling designs to obtain capture histories and thereby estimate the abundance of adult bull elephants in a globally important population in southern India. We validated these estimates against those obtained from an independent method combining line-transect density estimates with age–sex composition data for elephants. The sampled population was open to gains and losses between sampling occasions. The abundance of adult males in the 176 km2 study area was N(se N)= 134(14.2) and they comprised 14% ( ± 1%) of the total elephant population. Time-specific abundance estimates for each sampling occasion showed a distinct increase in adult male numbers over the sampling period, explained by seasonal patterns of local migration. CR-based estimates for adult male abundance closely matched estimates from distance-based methods. Thus, while providing abundance data of comparable rigour and precision, photographic CR methods permit estimation of demographic parameters for the Asian elephant that are both urgently needed and difficult to obtain.
