  • Killer whale genetics raise inbreeding questions
    on April 24, 2018 at 6:11 pm

    A new genetic analysis of Southern Resident killer whales found that two male whales fathered more than half of the calves born since 1990 that scientists have samples from, a sign of inbreeding in the small killer whale population that frequents Washington's Salish Sea and Puget Sound. […]

  • Land use and pollution shift female-to-male ratios in snapping turtles
    on April 24, 2018 at 5:36 pm

    Current research shows that increasing global temperatures as a result of climate change are expected to produce more female turtles since their offspring are influenced by the nest's temperature. But now, a team of biologists has found that the nesting environment of turtles in agricultural habitats, which can ultimately lower nesting temperatures, can actually produce more males. […]

  • 'Environmental DNA' used to identify killer whales in Puget Sound
    on April 23, 2018 at 5:50 pm

    When endangered killer whales swim through the sheltered waters of Puget Sound, they leave behind traces of 'environmental DNA' that researchers can detect as much as two hours later has found. […]

  • Museum researchers rediscover animal not seen in 30 years
    on April 19, 2018 at 9:27 pm

    Researchers have rediscovered the San Quintin kangaroo rat (Dipodomys gravipes) in Baja California. The Museum is partnering with Terra and local authorities on a conservation plan for the species, which was last seen in 1986, and was listed as endangered by the Mexican government in 1994. It was held as an example of modern extinction due to agricultural conversion. […]

  • Unprecedented wave of large-mammal extinctions linked to prehistoric humans
    on April 19, 2018 at 6:15 pm

    Homo sapiens, Neanderthals and other recent human relatives may have begun hunting large mammal species down to size -- by way of extinction -- at least 90,000 years earlier than previously thought, according to a new study. The magnitude and scale of the extinction wave surpassed any other recorded during the last 66 million years, according to the study. […]

  • How well does the greater sage grouse habitat protects other species?
    on April 18, 2018 at 6:13 pm

    Protected areas for sage grouse don't necessarily serve the needs of other species that depend on sagebrush habitat, showing that the bird might not be as much of an umbrella species as had been assumed. […]

  • How to improve habitat conservation for migrating cranes
    on April 18, 2018 at 1:20 pm

    Every year, endangered whooping cranes travel along a 4,000-kilometer corridor linking their Canadian nesting grounds and their winter home in Texas. Habitat in their path through the northern Great Plains is being lost at an alarming rate, but identifying key spots for protection is a challenge. Now, researchers behind a new study have created a model of whooping crane habitat use with the potential to greatly improve the targeting of conservation efforts during their migration. […]

  • Dinosaurs ended -- and originated -- with a bang!
    on April 16, 2018 at 2:58 pm

    It is commonly understood that the dinosaurs disappeared with a bang -- wiped out by a great meteorite impact on the Earth 66 million years ago. But their origins have been less understood. In a new study, scientists show that the key expansion of dinosaurs was also triggered by a crisis -- a mass extinction that happened 232 million years ago. […]

  • A new hope: One of North America's rarest bees has its known range greatly expanded
    on April 16, 2018 at 12:59 pm

    The Macropis cuckoo bee is one of the rarest bees in North America, partly because of its specialized ecological associations. It is a nest parasite of oil-collecting bees of the genus Macropis which, in turn, are dependent on oil-producing flowers of the genus Lysimachia. However, new data greatly expands the known range of the cuckoo, and has implications for its conservation status. […]

  • Genetic evidence that magnetic navigation guides loggerhead sea turtles
    on April 12, 2018 at 6:11 pm

    New research provides valuable insight into the navigation and nesting behaviors of loggerhead sea turtles that could inform future conservation efforts. Loggerhead sea turtles that nest on beaches with similar magnetic fields are genetically similar to one another, according to a new study. […]

  • Animal images used in marketing may skew public perception about their survival risks
    on April 12, 2018 at 6:10 pm

    Many of the world's most charismatic animal species -- those that attract the largest interest and deepest empathy from the public -- are at high risk of extinction in part because many people believe their iconic stature guarantees their survival. […]

  • New method prioritizes species for conservation in the face of uncertainty
    on April 11, 2018 at 6:51 pm

    Biologists have discovered for the first time extensive deep-water seagrass meadows in the middle of the vast Indian Ocean through satellite tracking the movement of green sea turtles. […]

  • Why the Tasmanian devil might be more susceptible to transmissible cancers
    on April 9, 2018 at 4:04 pm

    Cancers that can jump from one animal to another of the same species are rare, but the endangered Tasmanian devil is doubly unlucky: in recent years, two transmissible cancers affecting them have been identified. A comparison of these cancers suggests that they are similar in origin, leading researchers to believe that devils may be at greater risk for these kinds of diseases. […]

  • Climate change is wreaking havoc on delicate relationship between orchids and bees
    on April 6, 2018 at 12:55 pm

  • The ban of the cave bear
    on April 5, 2018 at 2:01 pm

    At 3.5 meters long and with a shoulder height of 1.7 meters, the cave bear was one of the giants of the Ice Age. Yet few appear to have survived until the last glacial maximum 24,000 to 19,000 years ago. Researchers have conducted analyses to find out what likely caused the extinction of these large herbivores. It is believed that the renewed cooling of the climate and hunting by humans -- added to the bears purely vegetarian diet -- increased the pressure on this megafauna species. […]

  • Diving deep into the blue whale genome reveals the animals’ extraordinary evolutionary history
    on April 5, 2018 at 1:53 pm

    For the first time, scientists have deciphered the complete genome of the blue whale and three other rorquals. These insights now allow tracking the evolutionary history of the worlds’ largest animal and its relatives in unprecedented detail. Surprisingly, the genomes show that rorquals have been hybridizing during their evolutionary history. In addition, rorquals seem to have separated into different species in the absence of geographical barriers. This phenomenon, called sympatric speciation, is very rare in animals. […]

  • Eating less enables lemurs to live longer
    on April 5, 2018 at 1:32 pm

    Chronic caloric restriction strongly increases the lifespan of a small primate, the grey mouse lemur. This is one of the results of a ten-year experiment. Chronic caloric restriction consists in eating a reduced but balanced diet from the outset of early adulthood. Its beneficial effect on lifespan had been established for many short-lived species (worms, flies, mice), but remained controversial for primates, including humans. […]

  • Lizards, mice, bats and other vertebrates are important pollinators, too
    on April 4, 2018 at 10:25 pm

    Although less familiar as flower visitors than insect pollinators, vertebrate pollinators are more likely to have coevolved tight relationships of high value to the plants they service, supplying essential reproductive aid for which few or no other species may substitute. […]

  • Rare coastal martens under high risk of extinction in coming decades
    on April 4, 2018 at 8:36 pm

    The coastal marten, a small but fierce forest predator, is at a high risk for extinction in Oregon and northern California in the next 30 years due to threats from human activities. […]

  • Turtle shells help decode complex links between modern, fossil species
    on March 28, 2018 at 5:07 pm

    A new study shows how scientists can use animals' physical features -- also known as morphology -- to make connections between a modern species and its fossilized relatives, even if they look strikingly different. […]

  • Sea turtles use flippers to manipulate food
    on March 28, 2018 at 12:34 pm

    Sea turtles use their flippers to handle prey despite the limbs being evolutionarily designed for locomotion. Research reveals a behavior thought to be less likely in marine tetrapods is actually widespread and that this type of exaptation of flippers may have been occurring 70 million years earlier than previously thought. […]

  • Iconic swallowtail butterfly at risk from climate change
    on March 27, 2018 at 11:43 pm

    New research reveals that Norfolk's butterflies, bees, bugs, birds, trees and mammals are at major risk from climate change as temperatures rise. Researchers carried out the first in-depth audit of its kind for a region in the UK to see how biodiversity might be impacted in Norfolk as the world warms. The study finds that the region's Swallowtail Butterfly, which can't be found anywhere else in the UK, is at risk -- along with three quarters of bumblebee, grasshopper and moth species. […]

  • Mass extinction with prior warning
    on March 27, 2018 at 2:26 pm

    Mass extinctions throughout the history of the Earth have been well documented. Scientists believe that they occurred during a short period of time in geological terms. In a new study, paleobiologists have now shown that signs that the largest mass extinction event in the Earth's history was approaching became apparent much earlier than previously believed, and point out that the same indicators can be observed today.
