  • Marine mammals and sea turtles recovering after Endangered Species Act protection
    on January 16, 2019 at 7:06 pm

    More than three-quarters of marine mammal and sea turtle populations have significantly increased after listing of the US Endangered Species Act (ESA), according to a new study. […]

  • Urbanization may hold key to tiger survival
    on January 16, 2019 at 4:55 pm

    A new study says the future of tigers in Asia is linked to the path of demographic transition -- for humans. […]

  • Vampire bat venom could hold key to new medical treatments
    on January 16, 2019 at 4:11 pm

    Vampire bats could hold the key to new treatments for a range of serious medical problems, but researchers have hit a snag accessing the specimens needed to advance their work. Now scientists have found a new class of blood pressure-regulating peptides in the venom of the common vampire bat (Diphylla ecaudata). […]

  • Ocean giant gets a health check: Combination blood, tissue test reveals whale shark diets
    on January 16, 2019 at 2:06 pm

    Whale sharks, the world's largest fish, likely endure periods of starvation and may eat more plants than previously thought, according to the first results of a new health check. Ocean scientists now have a powerful, simple tool to discover the diets, migrations, and conservation needs of this endangered species. […]

  • Idled farmland presents habitat restoration opportunities in San Joaquin Desert
    on January 15, 2019 at 9:23 pm

    Most of the native habitat in California's San Joaquin Desert has been converted to row crops and orchards, leaving 35 threatened or endangered species confined to isolated patches of habitat. A new study looked at the conservation potential of marginal farmland in the San Joaquin Desert and found that restoration of fallowed farmland could play a crucial role in habitat protection and restoration strategies for the blunt-nosed leopard lizard and other endangered species. […]

  • Genomic study finds Haida Gwaii's northern goshawks are highly distinct and at-risk
    on January 15, 2019 at 4:20 pm

    Haida Gwaii's small population of northern goshawks -- already of great concern to conservationists -- are the last remnant of a highly distinct genetic cluster of the birds, according to a new genomic analysis. […]

  • Bear necessities: New study highlights importance of water resources for Andean bears
    on January 15, 2019 at 3:48 pm

    A new study highlights the importance of water for Andean bears living in the mountain forests of Peru. The study found that bears exhibit tree-rubbing behavior on shrubs and trees that are located on trails near water holes. The discovery that this behavior occurs near water holes could have implications for future conservation programs. […]

  • Central Texas salamanders, including newly identified species, at risk of extinction
    on January 14, 2019 at 9:11 pm

    Biologists have discovered three new species of groundwater salamander in Central Texas, including one living west of Austin that they say is critically endangered. They also determined that an already known salamander species near Georgetown is much more endangered than previously thought. They warn that more severe droughts caused by climate change and increasing water use in Central Texas have left groundwater salamanders 'highly vulnerable to extinction.' […]

  • New mathematical model can help save endangered species
    on January 11, 2019 at 4:28 pm

    One of the greatest challenges in saving endangered species is to predict if an animal population will die out. Accurate and reliable models are crucial for conservationists. […]

  • Far-ranging fin whales find year-round residence in Gulf of California
    on January 10, 2019 at 9:09 pm

    Researchers from Mexico and the United States have concluded that a population of fin whales in the rich Gulf of California ecosystem may live there year-round -- an unusual circumstance for a whale species known to migrate across ocean basins. […]

  • Where will the world's next Zika, West Nile or Dengue virus come from?
    on January 4, 2019 at 6:12 pm

    Scientists have identified wildlife species that are the most likely to host flaviviruses such as Zika, West Nile, dengue and yellow fever. They created a global flavivirus hotspot map from their findings. […]

  • Historical genomes reveal recent changes in genetic health of eastern gorillas
    on December 27, 2018 at 4:14 pm

    The critically endangered Grauer's gorilla has recently lost genetic diversity and has experienced an increase in harmful mutations, according to researchers who sequenced 11 genomes from eastern gorilla specimens collected up to 100 years ago, and compared these with genomes from present-day individuals. […]

  • Genetics of California mountain lions: Research to inform future conservation
    on December 21, 2018 at 7:25 pm

    Mountain lions in California exhibited strong population genetic structure, and some California populations had extremely low levels of genetic diversity, with some exhibiting estimates as low as the endangered Florida panther. […]

  • Wildlife struggle to cope with extreme weather
    on December 21, 2018 at 5:37 pm

    The mass death of flying foxes in extreme heat in North Queensland last month underscores the importance of wildlife research released today. The new research sheds light on how various species have responded to major climate events. […]

  • Warming warning over turtle feminization
    on December 20, 2018 at 12:10 am

    Up to 93 percent of green turtle hatchlings could be female by 2100, as climate change causes 'feminization' of the species, new research suggests. […]

  • Groups of pilot whales have their own dialects
    on December 19, 2018 at 4:55 pm

    A new study has found that short-finned pilot whales living off the coast of Hawai'i have their own sorts of vocal dialects, a discovery that may help researchers understand the whales' complex social structure. […]

  • New insights on animal movement in fire-prone landscapes
    on December 19, 2018 at 12:58 pm

    A new article considers how fire histories affect animals' movement and shape the distribution of species. […]

  • Optimizing restoration can deliver an eightfold increase in cost-effectiveness
    on December 18, 2018 at 7:42 pm

    A new study presents a novel approach to identify optimal priority areas for restoration, considering multiple criteria such as biodiversity conservation, climate change mitigation and reduction of costs. In a context of multiple local, national and global targets for ecosystem restoration, the study presents a flexible tool capable of increasing restoration cost-effectiveness by up to eight times. […]

  • Explaining differences in rates of evolution
    on December 18, 2018 at 3:03 pm

    Scientists look to fossils and evolutionary trees to help determine the rate of evolution -- albeit with conflicting results. A new model has helped to resolve these contradictions. […]

  • Using endangered barbary macaques as photo props could negatively impact Moroccan tourism
    on December 18, 2018 at 12:47 pm

    Wild animals are increasingly exploited for entertainment and photo opportunities. A new study highlights that tourists in Morocco object to the use of barbary macaques as photo props, raising concerns about the animal's welfare and risk to human health. […]
