  • Elephants worth more alive, than when they are poached for ivory

    Elephants are worth 76 times more when they’re alive than dead, according to a new analysis released this past weekend. The report follows on the heels of findings by WWF that the world has lost 50 percent of its wildlife over the past 40 years, with more than half of African elephants killed for ivory…

  • No longer able to find sea ice, walruses turn to land

    A mass of thousands of walruses were spotted hauled up on land in northwest Alaska during NOAA aerial surveys earlier this week. An estimated 35,000 occupied a single beach – a record number illustrating a trend in an unnatural behavior scientists say is due to global warming. Walruses (Odobenus rosmarus)—iconic arctic mammals that are only…

  • “Global Roadmap” Created to Balance Development with Environmental Protection

    Roads make it possible to bring goods to market, to get to the office, to log a forest, to hunt its wildlife. Without roads, human society as we know it could not exist. However, to build roads, trees must be cleared and swamps drained, shrinking valuable wildlife habitat and fragmenting populations in the process. A…

  • A Fine Line : New Program Predicts When Human Impact Becomes Too Much

    Scientists at Stanford University recently unveiled a new modeling program that can predict the response of the environment to the land-use changes of human communities. Using their model, they found that natural resources can support humanity – up to a certain point. They recently published their findings in the journal Environmental Modelling & Software.

  • Trawling: destructive fishing method is turning sea floors to ‘deserts’

    Bottom trawling is a practice used by commercial fisheries around the world in which a large, heavy net is dragged along the ocean floor to scoop up everything in its path. Previous research has linked trawling to significant environmental impacts, such as the harvest of large numbers of non-target species, collectively termed “by catch,” as…

  • Scientists discover giant sperm fossilized in bat guano

    In a cave in Australia, researchers from the University of New South Wales discovered giant fossilized sperm. The sperm were produced 17 million years ago by a group of tiny, shelled crustaceans called ostracods, making them the oldest fossilized sperm ever found. The results were published recently in Proceedings of the Royal Society B. The…

  • Coral Yields Medically Useful Compounds

    In the waters off the coast of northern Australia lives a species of feathery coral. Years ago, bits of it were collected by the Australian Institute of Marine Science and stored at the National Cancer Institute’s extract repository, along with 200,000 other samples. When researchers retrieved and tested it, they found that it was very…

  • After Widespread Deforestation, China Bans Commercial Logging in Northern Forests

    Forestry authorities in China have stopped commercial logging in the nation’s largest forest area, marking an end to more than a half-century of intensive deforestation that removed an estimated 600 million cubic meters (21 billion cubic feet) of timber. The logging shutdown was enacted in large part to protect soil and water quality of greater…

  • Revealed For The First Time: The Surprising Biodiversity Of Algae ‘Reefs’

    Most people are familiar with coral reefs, but very few have ever heard of their algal equivalent – rhodolith beds. Yet, these structures provide crucial habitat for many marine species. In the first study of its kind, published in mongabay.com’s Tropical Conservation Science, researchers unveil just how important these beds are for bottom-dwelling organisms, and…

  • American cougars on the decline: ‘We’re running against the clock,’ says big cat expert

    It holds the Guinness World Record for having the most names of any animal on the planet, with 40 in English alone. It’s also the widest-ranging native land animal in the Americas, yet is declining throughout much of its range. Mongabay talks with big cat expert Dr. Howard Quigley about the status and research implications…
