A model of the effects of climate change on African vegetation from 1850 to 2100 predicts increases in woody plant cover, but considerable heterogeneity in the timing of these shifts dampens the shock that these changes in land-surface properties may represent to the Earth system.

President Mahinda Rajapaksa ordered the relevant officials to take immediate measures to protect wildlife and halt timber rackets.

SILCHAR: In order to resolve the raging controversy over the construction of Barak dam, both Delhi and Dhaka have agreed for an expert-meet on August 27 in the national capital.

Using information on current species distributions and dispersal traits, this study forecasts climate-driven range dynamics of plant species across the European Alps. Simulations predict moderate range contractions over the twenty-first century; however, more severe effects of climate warming on mountain plant diversity are expected in the longer term.

Increasing shrub cover on Arctic tundra is linked to climate warming, which is partially amplified by sea ice feedbacks, but the nature of these interactions remains poorly understood. Now research indicates that tundra plant productivity in late spring relates to sea-ice-driven temperature amplification but that the growing season peak is more closely associated with persistent large-scale atmospheric circulation patterns.

Invasive species, pollution levels in Moyar need to be monitored

Even as biodiversity decline is reported in the national parks worldwide, Mudumalai and Anamalai tiger reserves in Tamil Nadu have shown positive trends in sustaining its rich variety of flora and fauna. The positive trend was the outcome of a study taken up in 60 reserves from various parts of the world by a team of biodiversity researchers numbering more than 200.

We investigated if elevated CO2 could alleviate the negative effect of high temperature on fruit yield of strawberry (Fragaria × ananassa Duch. cv. Toyonoka) at different levels of nitrogen and also tested the combined effects of CO2, temperature and nitrogen on fruit quality of plants cultivated in controlled growth chambers. Results show that elevated CO2 and high temperature caused a further 12% and 35% decrease in fruit yield at low and high nitrogen, respectively.

“Serious social and environmental violations,” says group

An independent fact-finding team has called for suspension of work related to the upcoming 4,000 MW Tata Mundra Ultra Mega Power Project (UMPP) in Gujarat, citing “serious social and environmental violations”. The team, led by former Chief Justice of Sikkim S.N. Bhargava, released a report –‘The Real Cost of Power’- and presented the findings from the ground. “The project has disproportionately high social, environmental, and economic costs.

The proportion of organisms exposed to warm conditions is predicted to increase during global warming. To better understand how bats might respond to climate change, we aimed to obtain the first data on how use of torpor, a crucial survival strategy of small bats, is affected by temperature in the tropics. Over two mild winters, tropical free-ranging bats (Nyctophilus bifax, 10 g, n = 13) used torpor on 95% of study days and were torpid for 33.5±18.8% of 113 days measured.
