  • The recent spread of coyotes across North America did not doom deer populations
    on March 20, 2019 at 2:21 pm

    Coyotes eat deer, but not enough to limit the deer population at a large scale. A new study of deer numbers across the eastern United States has found that the arrival and establishment of coyote predators has not caused the number of deer harvested by hunters to decline. […]

  • Woolly star plants need catastrophes to live
    on March 19, 2019 at 5:51 pm

    The endangered Santa Ana Woolly Star depends on catastrophic floods. Thanks to a huge dam, natural floods are now nonexistent in its home turf. Researchers use different soil treatments mimicking flood effects in its preferred habitat, exploring the effectiveness of each towards plant survival. […]

  • Back to the drawing board for conservationists battling against infectious parrot disease
    on March 18, 2019 at 4:10 pm

    A study into the effectiveness of disinfecting birds' nests has led to a breakthrough in the understanding of biosecuity measures for the endangered echo parakeet in Mauritius. The research team found that annual disinfection of parakeet nest sites prior to the breeding season, intended to reduce the spread of infectious disease in endangered parrot species, didn't have the impact conservationists expected leading to recommendation for a different approach. […]

  • Tracking turtles with telemetry
    on March 14, 2019 at 7:16 pm

    A new model has been created that can forecast the location of Eastern Pacific leatherback turtles along the coast of Central and South America in an effort to decrease bycatch mortality of this critically endangered and ecologically important species. […]

  • Sea otters' tool use leaves behind distinctive archaeological evidence
    on March 14, 2019 at 3:09 pm

    Researchers have analyzed the use by sea otters of large, shoreline rocks as 'anvils' to break open shells, as well as the resulting shell middens. The researchers used ecological and archaeological approaches to identify patterns that are characteristic of sea otter use of such locations. By looking at evidence of past anvil stone use, scientists could better understand sea otter habitat use. […]

  • Climate change could devastate painted turtles
    on March 13, 2019 at 3:47 pm

    Climate change could contribute to the demographic collapse of the painted turtle, a species that has temperature-dependent sex determination. A scientist is sounding the alarm about the painted turtle's future in a new study. […]

  • Little owls on the move
    on March 12, 2019 at 4:37 pm

    New study on an owl's re-colonization of northern Switzerland. […]

  • UK wild newt species free from flesh-eating fungus for now...
    on March 12, 2019 at 11:59 am

    The UK's wild newt populations seem to be free from a flesh-eating lethal fungus known to be prevalent in privately-owned amphibians across Western Europe, a nationwide investigation has found. […]

  • Unprecedented number of warm-water species moved northward during marine heatwave
    on March 12, 2019 at 11:59 am

    A new study documents an unprecedented number of southern marine species moving northward into California and as far north as Oregon during the 2014-2016 marine heatwave. Of 67 rare, warm-water species sightings observed, 37 had never been documented so far north before. […]

  • In developing nations, national parks could save endangered species
    on March 7, 2019 at 9:19 pm

    A new study of animal populations inside and outside a protected area in Senegal, Niokolo-Koba National Park, shows that protecting such an area from human interaction and development preserves not only chimps but many other mammal species. […]

  • Chimpanzees lose their behavioral and cultural diversity
    on March 7, 2019 at 7:10 pm

    Chimpanzees are well known for their extraordinary diversity of behaviors, with some behaviors also exhibiting cultural variation. An international research team has investigated whether chimpanzee behavioral diversity is reduced under high human impact. By comparing sets of chimpanzee behaviors across a large number of social groups exposed to different levels of human disturbance, the scientists found a reduction in behavioral diversity when human impact was high. […]

  • Insects in decline: On farmland, latecomers lose out
    on March 7, 2019 at 3:32 pm

    Wild bees in Europe are in trouble -- more than 50 percent of local species are now classified as endangered. Recent findings indicate that, in farming areas, species that emerge in late summer are most acutely threatened. […]

  • Crucial milestone for critically endangered bird
    on March 7, 2019 at 3:31 pm

    A team led by a conservation biologist has successfully relocated threatened Seychelles paradise flycatchers (Terpsiphone corvina) to a different island to help prevent their extinction. Four females and two males were caught on Denis Island and taken to Curieuse Island, where they joined 11 males and nine females who were moved there from La Digue Island at the end of last year. Four weeks after that release, the first birds had nested, with the first chick recently fledged. […]

  • Disrupting wolf movement may be more effective at protecting caribou
    on March 6, 2019 at 5:53 pm

    Researchers used motion-triggered cameras to capture photographs of wolves, caribou, and other wildlife species in the Canadian Oil Sands to study the habitat use patterns of these animals and test management strategies aimed at reducing the impacts of the linear developments on caribou. […]

  • Dinosaurs were thriving before asteroid strike that wiped them out
    on March 6, 2019 at 1:17 pm

    Dinosaurs were unaffected by long-term climate changes and flourished before their sudden demise by asteroid strike, according to new research. […]

  • Owls against owls in a challenge for survival
    on March 5, 2019 at 8:36 pm

    Scientists are puzzling out how to address the declining numbers of northern spotted owls (NSO) in their Pacific Northwest forest habitat. A new study explores the reasons why spotted owls are losing a foothold in their habitat, forecasts future habitat conditions and species interactions, and suggests best management practices. […]

  • Ancient mammal remains digested by crocodiles reveal new species
    on March 4, 2019 at 6:42 pm

    Fossilized bones that appear to have been digested by crocodiles in the Cayman Islands have revealed three new species and subspecies of mammal that roamed the island more than 300 years ago. […]

  • Biodiversity crisis: Technological advances in agriculture are not a sufficient response
    on March 4, 2019 at 5:15 pm

    Rapid population and economic growth are destroying biodiversity. A growing demand for agricultural products requires ever new cultivated areas. Even though technological advances are making agriculture more efficient, the growing population makes up for these successes. Effective nature conservation needs concepts against population growth and for sustainable consumption. […]

  • Alien species are primary cause of recent global extinctions
    on March 4, 2019 at 2:14 am

    Alien species are the main driver of recent extinctions in both animals and plants, according to a new study. Scientists found that since 1500, alien species have been solely responsible for 126 extinctions, 13 percent of the total number studied. […]

  • Endangered eel located using DNA from one liter of water
    on March 1, 2019 at 3:18 pm

    Researchers have shed light on the distribution of Japanese eel by analyzing environmental DNA (eDNA) from small samples of river water. This could enable faster and more effective surveys of Japanese eel populations, and help to conserve this endangered species. […]
