Pterocarpus santalinus L.f. (Red Sanders) is an endemic and endangered species largely confined to the southern portion of the Eastern Ghats, Andhra Pradesh, India. To understand its ecological and geographic distribution, we used ecological niche modelling (ENM) based on field sample-based distributional information, in relation to climatic and topographic datasets. Before modelling, hierarchical partitioning was used to optimize the choice of variables for better

Characterization, quantification and monitoring of biodiversity have been among the major challenges in biodiversity conservation. Until recently, spatial ecological database in India was almost non-existent. There is need of a robust and quality database of the biological diversity at species, community, ecosystem and landscape levels for identification of vulnerable ecosystems and risk species. In order to have a national level database on the spatial distribution of

Sal (Shorea robusta Gaertn. f.) is a dominant tree species, whose natural range lies between 20–32°N lat. and 75–95°E long., is spread across 10 million ha in India. Species distribution models predict the species geographic ranges from occurrence records and sitespecific environmental data. Here, we have (i) generated the 1960s scenario for sal species on the basis of the existing published literature; (ii) confirmed the species occurrence data using satellite imagery for the

The closed evergreen forest, called the shola, occurs above 1700 m in patches in the higher hills of South India in the
Nilgiris, Annamalai and Palani hills. Sholas are patches of stunted evergreen tropical montane forests which attain a
low height of about 16–20 m. These forests have high ecological significance in protecting the head waters of rivers by
holding up of water received by precipitation like a sponge, thus preventing rapid run-off. (Correspondence)

Help of local self-government institutions to be sought

The Kerala State Biodiversity Board (KSBB) is preparing to launch a campaign highlighting the need to prevent the destruction of plants during sanitation drives taken up by local self-government institutions.Board chairman R.V. Varma told The Hindu that directions would be communicated to local bodies to sensitise workers engaged for projects taken up under the Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGS) .

GUWAHATI, April 17 – Governor JB Patnaik today asked the authorities concerned to take urgent steps for making the Majuli Cultural Landscape Management Authority (MCLMA) fully functional.

It's chemistry's greatest challenge – inventing systems that turn water and sunshine efficiently into cheap, clean energy for all.

Plant phenology models, especially leafing models, play critical roles in evaluating the impact of climate change on the primary production of temperate plants. Existing models based on temperature alone could not accurately simulate plant leafing in arid and semi-arid regions.

Climate models for the coming century predict rainfall reduction in the Amazonian region, including change in water availability for tropical rainforests. Here, we test the extent to which climate variables related to water regime, temperature and irradiance shape the growth trajectories of neotropical trees. We developed a diameter growth model explicitly designed to work with asynchronous climate and growth data.

The Survey of India, compiled in 1975, marked around 1,000 water bodies with unique aquatic flora and fauna in the state capital. In fact, Hyderabad then was called the “City of Lakes”. But that was then.

When the HMDA did a count a year ago for the Lake Protection Committee, the officials could list only about 400 lakes in areas within its jurisdiction. Signi-ficantly, experts said, the number of waterbodies that have disappeared would be higher, considering HMDA’s jurisdiction comprises four districts. And if the ‘disappearance’ of about 600 lakes in 35-odd years isn’t alarming enough, even waterbodies that still exist have shrunk, with encroachments on the periphery.
