Wetlands are amongst the Earth's most productive ecosystems. In Bangladesh these are of great importance because of the extensive food webs and rich biodiversity they support. In the past, wetlands have been undervalued.

The National Green Tribunal has sought the reply of Union Ministry of Environment and Forests (MoEF) on a plea against grant of any clearance to any new project in ecologically sensitive Western Ghats.

The Tribunal also issued notices to the state governments of Maharashtra, Karnataka, Goa, Kerala, Gujarat and Tamil Nadu seeking their replies on the plea for implementation of the report by Western Ghats Ecology Expert Panel (WGEEP) on the protection and preservation of Western Ghats.

A Recent Study Notes 13 Direct Sightings Of The Mammal In Gulf Of Kutch

Ahmedabad: The rare dugong, also known as ‘sea cow’, is happily grazing underwater off the Gujarat coast. Until now, wildlife experts had known about the existence of the marine mammal largely through carcasses being washed ashore along the state and sightings by fishermen. But now there is some concrete evidence.

MIRZA, May 27 – In a significant development which may be a serious environmental concern, a huge Gangetic river dolphin was killed in the river Brahmaputra recently (the decayed carcass was detect

The Biodiversity Management Committees of the coastal local bodies will be actively involved in the campaign. Information on declining marine biodiversity, threats faced by the marine ecosystem, sustainable livelihood and conservation measures will be highlighted, he said.

The Kerala campaign will be led by the district coordinators of the board in association with experts in conservation, ecology and environment. The programme is funded by the National Biodiversity Authority.

An engineered influenza virus based on a haemagglutinin protein from H5N1 avian influenza, with just four mutations, can be transmitted between ferrets, emphasizing the potential for a human pandemic to emerge from birds.

Highly pathogenic avian H5N1 influenza A viruses occasionally infect humans, but currently do not transmit efficiently among humans. The viral haemagglutinin (HA) protein is a known host-range determinant as it mediates virus binding to host-specific cellular receptors1, 2, 3. Here we assess the molecular changes in HA that would allow a virus possessing subtype H5 HA to be transmissible among mammals.

It is critical to assess the effectiveness of the tools used to protect endangered species. The main tools enabled under the U.S. Endangered Species Act (ESA) to promote species recovery are funding, recovery plan development and critical habitat designation. Earlier studies sometimes found that statistically significant effects of these tools could be detected, but they have not answered the question of whether the effects were large enough to be biologically meaningful.

The study tracked the waxing and waning of the range and diversity of families of mammals that inhabited the continental United States during this extended period.

Climate change alters species distributions, causing plants and animals to move north or to higher elevations with current warming. Bioclimatic models predict species distributions based on extant realized niches and assume niche conservation. Here, we evaluate if proxies for niches (i.e., range areas) are conserved at the family level through deep time, from the Eocene to the Pleistocene. We analyze the occurrence of all mammalian families in the continental USA, calculating range area, percent range area occupied, range area rank, and range polygon centroids during each epoch.
