ABSTRACT H5N1 influenza A viruses are widely distributed among poultry in Asia, but until recently, only a limited number of wild birds were affected. During late April through June 2005, an outbreak of H5N1 virus infection occurred among wild birds at Qinghai Lake in China. Here, we describe the features of this outbreak. First identified in bar-headed geese, the disease soon spread to other avian species populating the lake. Sequence analysis of 15 viruses representing six avian species and collected at different times during the outbreak revealed four different H5N1 genotypes. Most of the isolates possessed lysine at position 627 in the PB2 protein, a residue known to be associated with virulence in mice and adaptation to humans. However, neither of the two index viruses possessed this residue. All of the viruses tested were pathogenic in mice, with the exception of one index virus. We also tested the replication of two viruses isolated during the Qinghai Lake outbreak and one unrelated duck H5N1 virus in rhesus macaques. The Qinghai Lake viruses did not replicate efficiently in these animals, producing no evidence of disease other than transient fever, while the duck virus replicated in multiple organs and caused symptoms of respiratory illness. Importantly, H5N1 viruses isolated in Mongolia, Russia, Inner Mongolia, and the Liaoning Province of China after August 2005 were genetically closely related to one of the genotypes isolated during the Qinghai outbreak, suggesting the dominant nature of this genotype and underscoring the need for worldwide intensive surveillance to minimize its devastating consequences.

Trigonobalanus doichangensis is a national rare and endangered fagaceous plant of China. It is currently restricted to five sites, four in Yunnan province in south-western China and one in northern Thailand. We investigated the genetic diversity of T. doichangensis to provide information for the effective preservation of the genetic diversity of the species. Randomly amplified polymorphic DNA (RAPD) markers were used to assess the genetic variation and structure in each of the five extant populations. Sixteen primers produced 157 fragments, of which 83 (53%) were polymorphic. The estimated species diversity of T. doichangensis, although lower than for most fagaceous species, was within the range of values that have been reported for the family. The presence of private and/or uncommon fragments in each population, the presence of unique phenotypes in all individuals sampled, and estimates of relatively high populational fixation and low gene flow indicated that the species diversity present was mostly distributed among the five isolated extant populations. Pairwise genetic distances between populations were not correlated with geographical distances as depicted by the resolution of one of the Chinese populations as most similar to the Thailand population. Conservation of this species should include preservation of each of the five distinct extant populations.

The Eastern Ghats of Tamil Nadu have been poorly surveyed for birds.  The best known bird survey in the Eastern Ghats of Tamil Nadu (EGTN) was by V.S. LaPersonne who carried out the the Surveys in Tamilnadu Eastern Ghats between 08th April, 1929 and 25th July 1929. This was reported by WHistler & Kinnear.  Thereafter information about birds in EGTN has come only from checklists published from time to time, by researchers, whose primary focus was not birds.  Hence, to fill this lacuna, a comprehensive survey of birds was undertaken in the EGTN from March 2012-–--February 2015.  The objectives of the study were to document the avian richness and abundance in EGTN, put them in perspective to the Vernay Survey conducted more than 80 years back, and identify priority sites for bird conservation.  The study covered the hills and forests of Tamil Nadu spanning nine districts.  In total, 262 species of birds were recorded during the survey.  Eight species of birds fall under the threatened category.  Species such as Square-tailed Bulbul Hypsipetes (lecocephalus) ganeesa, Rufous Woodpecker Micropternus brachyurus, Asian Fairy Bluebird Irena puella, and Malabar Whistling Thrush Myophonus horsfieldii still persist in the same old sites reported in the Vernay Survey.  The top five abundant species were the Red-vented Bulbul Pycnonotus cafer, White-browed Bulbul Pycnonotus luteolus, Red-whiskered Bulbul Pycnonotus jocosus, Common Iora Aegithina tiphia, and Purple-rumped Sunbird Leptocoma zeylonica.  The Vaniyar riparian tract in the Shevroys, from its origins in the hills to the Vaniyar dam downstream, is a potential bird conservation site in the Eastern Ghats of Tamil Nadu.

  Birds are important bio-indicators and provide various ecosystem services including pollination, dispersal, and pest control. However, they are threatened by habitat loss, fragmentation, and degradation. Study on species diversity, relative abundance, and habitat associations of avifauna were conducted in Tara Gedam Monastery forest patch and associated habitats from July 2016 to April 2017. Stratified random sampling approach was used to classify habitats and select sampling plots based on vegetation type. Consequently, forest, bushland, farmland, and plantation habitats were used for data collection. Point count and line transect methods were used to collect data, and Shannon-Weiner and Simpson’s diversity indices were used to estimate the avian species diversity. One-way ANOVA was conducted to compare avian relative abundance and richness among the different habitat types. A total of 98 species of birds belonging to 14 orders and 41 families were recorded in Tara Gedam Monastery forest and associated habitats. Eighty-seven resident bird species and eleven Palearctic migrants were identified of which seven species are endemic to Ethiopia and Eritrea. The highest avian diversity (H’=4.23) was recorded in the study area during the wet season.The highest species similarity index (SI=0.47) was recorded between forest and bushland habitats during the wet season, while the lowest similarity index (SI=0.07) was found between bush-land and farmland habitats during the dry season. Species richness and relative abundance of bird species varied between the wet and dry seasons. Besides birds, Tara Gedam Monastery forest supports a large number of other wild fauna species, which indicates the area’s potential to support biodiversity. Therefore, there must be a collaborative work between the monastery and different governmental and non-governmental organizations to protect the entire ecosystem in order to conserve the whole biodiversity of the area in general and the avifauna in particular.
