Scientists in Canada's Arctic have discovered the fossil of a previously unknown web-footed carnivore that helps explain how seals developed from land-based mammals, a member of the team said on Wednesday.
The very primitive animal, measuring around 110 cm (43 inches) from nose to tail, had a body similar to that of an otter, with a skull more closely related to a seal.
Norway became on Wednesday the first Arctic state to agree limits to its northern seabed, stopping short of the North Pole in a regional territorial scramble driven partly by hopes of finding oil and gas.
Norway's newly defined continental shelf covers 235,000 sq kms (90,740 sq miles), or three-quarters the size of mainland Norway, Foreign Minister Jonas Gahr Stoere said.
The objective of this Pacific Ocean synthesis is to comprehensively and systematically survey the published scientific literature, government publications and other peer-reviewed reports to identify Pacific Ocean and regional threats as well as the environmental and socioeconomic impacts of those threats.
evolution Wolves from dogs Human beings can enrich biodiversity without doing much. Take raising dogs as pets, for example. A study says dogs have helped in the evolution of black colour in wolves. This bodes well for wolves inhabiting fast depleting snow-covered northern environments like the Arctic tundra. While hunting, the dark colour helps them merge with surroundings. Using
Fish can do it by producing and excreting carbonates THE marine carbon cycle is undergoing rapid changes. An excess of unregulated carbon will eventually acidify the oceans. A new study demonstrates that fish have the potential to save the marine carbon cycle. Until now scientists believed that the calcium carbonate (CaCO3), which makes seawater alkaline, came from the external
The marine environment is one of the most fascinating realm. Due to the physical and chemical conditions of the marine environment, almost every class of marine organism exhibits variety of molecules with unique structural features, which are not found in terrestrial natural products. Today researchers have isolated approximately 11,000 marine-derived natural products. (Editorial)
CORAL reefs are a major part of the coastal economy. Fishermen harvest corals for ornamental trade. But, reefs are at risk and there is very little data on what factors put them in the high-risk category. Listing some of the possibilities, Naveen Namboodiri, post-doctoral fellow at Ashoka Trust for Research in Ecology and Environment in Bangalore, said,
Tuticorin: A project on export-oriented marine value chain for farmed seafood production using Cobia (Rachycentron canadum) through rural entrepreneurship was sanctioned by National Agricultural Innovation Project. It would be done at a cost of Rs.264.89 lakh.
