The Western Ghats

The Rajiv Gandhi National Park encompasses a rich biodiversity of both flora and fauna and is regarded as one of the richest protected areas in Asia. It is a part of Nilgiri Biosphere Reserve and covers foot-hills of the Brahmagiri hill ranges in the Western Ghats, which is one of the world’s biodiversity hotspots and epicenter of Indian endemics harbouring species-rich-habitats and supporting a high biodiversity. This is evident in its flowering plants diversity brought to focus during the present study. The National Park spreads over an area of 643.39 km2, harbours 1337 species, 14 subspecies and 34 varieties of Angiosperms distributed over 754 genera and 152 families. Notably 110 species of these are endemic. A complete inventory of all the recorded species is provided here.

Nilgiri Langur

Phylogenetic conservatism or rapid anthropogenic habitat modifications could increase the incidences of interspecific associations of Hanuman and Nilgiri langurs (Family: Cercopithecidae, subfamily: Colobinae) in the southern Western Ghats.  Opportunistic surveys were conducted at the Silent Valley National Park, Kerala and around Devimalai Ghats, Tamil Nadu for  Tufted Grey-Nilgiri Langur association. Based on the observations from Researchers, field assistants, forest staff, and local people, the data in terms of the time of the sighting, number of individuals, phenotypes of individuals, and the time the interaction lasted, were recorded.  The study reports data on a troop of Nilgiri Langurs (N=13) around O Valley tea estate at Devimalai Ghat, Gudalur, Tamil Nadu with some hybrid looking individuals and a Tufted female Grey Langur amongst them. A total of six  and two uni-male troops of Nilgiri Langurs  and grey langurs respectively with Tufted female Grey Langurs, and aberrant coat colored infants observed at the Neelikkal section of Silent Valley National Park are also reported. The study reasonably speculates that there could be more such locations in the southern western ghats and emphasizes the need for more systematic surveys to understand  and explore the ecology, behavior, molecular, and other likely factors contributing to the conservation of vulnerable Nilgiri langur (Semnopithecus johnii) populations.

Different Levels

Lantana camara is a dominant invasive shrub in many protected areas of India including the Nilgiri Biosphere Reserve (NBR).  We conducted a study to assess the regeneration potential of endemic native (shola) trees under different levels of Lantana infestation in the upper plateau of NBR.  A total of 61 plots in a total area of 0.73ha were sampled, out of which 0.57ha was in Lantana dominated sites and 0.16ha in undisturbed shola forests.  The plots were classified as per the level of Lantana infestation (intensive, moderate, and low infestation). We found that regeneration of shola trees, including endemics decreased with increasing intensity of Lantana invasion.  No regeneration occurred in the intensively infested plots whereas regeneration was high in undisturbed shola forests.

A New Species

Here we describe and illustrate Syllophopsis peetersi sp. nov. from Silent Valley National Park, a biodiversity hotspot region of the Western Ghats of India. The discovery also marks a first native report of the genus from the Indian subcontinent. Scanning Electron Microscopy (SEM) analysis was carried out to elucidate the general morphology and sensilla of the new species. The new species is similar to congeners from Madagascar, but with larger differences from species that occur elsewhere.
