Discover the world's most endangered species Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth. With the help of over 7,000 of the world’s best wildlife filmmakers and photographers, conservationists and scientists, Arkive.org featured multi-media fact-files for more than 16,000 endangered species. Freely accessible to everyone, over half a million people every month, from over 200 countries, used Arkive to learn and discover the wonders of the natural world. Since 2013 Wildscreen was unable to raise sufficient funds from trusts, foundations, corporates and individual donors to support the year-round costs of keeping Arkive online. Therefore, the charity had been using its reserves to keep the project online and was unable to fund any dedicated staff to maintain Arkive, let alone future-proof it, for over half a decade. Therefore, a very hard decision was made to take the www.arkive.org website offline in February 2019.
Association pour la sauvegarde de la biodiversité TENDUA a été créée en 2008, après un voyage en Inde où, en dépit de nombreux parcs nationaux, la faune sauvage et ses habitats sont menacés. Le constat est malheureusement planétaire : partout dans le monde, la biodiversité est en danger, sur terre et dans les mers. La 6e extinction majeure de biodiversité est en cours : en 150 ans l’homme a réussi à détruire son environnement comme il ne l’avait jamais fait auparavant. Les précédentes extinctions connues des scientifiques étaient le résultat d’un processus évolutionnaire ; or aujourd’hui, l’équilibre de la planète est menacé par les activités humaines. En août 2013, il a été estimé que l’humanité, par sa consommation effrénée, a dépassé la capacité de régénération de la Terre. Cela étant, nous n’avons plus le temps d’être pessimistes. Une nouvelle relation entre l’homme et la nature TENDUA propose à chacun de réfléchir à un nouveau type de relation entre l’homme et la nature. Adhésions et partenariats Comment adhérer ?
Orion Magazine - nature / culture / place Mount Tamalpais Bootjack Campground Now Open - Volunteer Camp Host Needed State Parks is proud to announce the opening of Mt. Tam's Bootjack Campground. This campground boasts stunning views and is open to campers on a first-come, first-served basis. Mark your calendars in late April. Mt. Mt. Just north of San Francisco's Golden Gate is Mount Tamalpais. On a clear day, visitors can see the Farallon Islands 25 miles out to sea, the Marin County hills, San Francisco and the bay, hills and cities of the East Bay, and Mount Diablo. Coastal Miwok Indians lived in the area for thousands of years before Europeans arrived. With the Gold Rush of 1849, San Francisco grew and more people began to use Mount Tamalpais for recreation. Facilities and ActivitiesHiking and Bicycle Trails: More than 50 miles of hiking trails are within the park and connect to a larger, 200 mile long trail system. The Bootjack Picnic Area has tables, stoves, piped drinking water and flush toilets.
Cetaceans Have Complex Brains for Complex Cognition Citation: Marino L, Connor RC, Fordyce RE, Herman LM, Hof PR, Lefebvre L, et al. (2007) Cetaceans Have Complex Brains for Complex Cognition.

The brain of a sperm whale is about 60% larger in absolute mass than that of an elephant. Recently, Manger [8] made the controversial claim that cetacean brains are large because they contain an unusually large number of thermogenic glial cells whose numbers increased greatly to counteract heat loss during a decrease in ocean temperatures in the Eocene-Oligocene transition.

UNEP-WCMC Wildcare Destroying the Indestructible: The Search for a Starfish Killer "There were more babies in one year than in the previous 20 years combined, in some places," Raimondi says. "We'll just see how that translates into recovery. If the disease is still present, they may die." Hewson says he isn't surprised. There are always oscillations in the populations of echinoderms and other insects over time, he says, booms and busts that are the dance between predators and prey. Of course, the very nature of a virus means it rarely kills off its host population entirely. Starfish, of course, aren't a species easily eradicated, mostly because they can be almost indestructible when they're healthy. Caren Chesler From a biological standpoint, starfish have an unusual anatomy. In the name of research, scientists have thrown everything they can at starfish to test their limits. "We can take bacteria that we culture from the environment, in an incredibly high density, until its milky white, and they still don't die," Hewson says.
