• Super hearing: University of Toronto scientists study fly to develop better hearing aids

    Ormia ochracea's sense of directional hearing is second to none in the animal kingdom.

    “These flies have highly specialized ears that provide the most acute directional hearing of any animal,” says Andrew Mason, an associate professor of biology at U of T Scarborough.  “The mechanism that makes their hearing so exceptional has even led to a range of bio-inspired technology, like the mini-directional microphones used in hearing aids.”

  • Rare Footage Helps Explain What Narwhals Use Their Tusks For

    Scientists are marveling over never-before-seen footage of narwhals that has brought to light new evidence for what those unicorn-like tusks are actually used for.

  • Estimating the size of animal populations from camera trap surveys

    Remote motion-sensitive photography, or camera trapping, is revolutionizing surveys of wild animal populations. Camera trapping is an efficient means of detecting rare species, conducting species inventories and biodiversity assessments, estimating site occupancy, and observing behaviour. If individual animals can be identified from the images obtained, camera trapping data can also be used to estimate animal density and population size – information critical to effective wildlife management and conservation.

    For this reason, camera traps were initially popularized by researchers studying big cats and other species with distinctive coat markings. Since then, thousands of camera traps have been deployed in wildlife habitat across the globe, especially in tropical forest ecosystems where animals are difficult to survey by other means. However, methods for estimating abundances of species which cannot be individually identified are still in development, and none is generally accepted or broadly applied.

  • EPA Asked to Reject Expanded Use of Medically Important Antibiotic on Citrus Crops

    The Center for Biological Diversity and Johns Hopkins Center for a Livable Future today asked the Environmental Protection Agency to reject a pesticide company’s request to permanently approve the use of a medically important antibiotic called oxytetracycline as a herbicide on citrus crops.

  • Neonic Pesticides Threaten Wild Bees' Breeding: Study

    Neonicotinoid pesticides hinder wild queen bumblebees’ reproductive success, according to a new University of Guelph study.

    The study is the first to link exposure to thiamethoxam — one of the most commonly used neonicotinoid pesticides — to fewer fully developed eggs in queens from four wild bumblebee species that forage in farmland.

  • Global warming kills gut bacteria in lizards

    Climate change could threaten reptiles by reducing the number of bacteria living in their guts, new research suggests.

    Scientists from the University of Exeter and the University of Toulouse found that warming of 2-3°C caused a 34% loss of microorganism diversity in the guts of common lizards (also known as viviparous lizards).

  • Scottish badgers highlight the complexity of species responses to environmental change

    In a new study researchers have found that although warmer weather should benefit badger populations, the predicted human population increase in the Scottish highlands is likely to disturb badgers and counteract that effect. These results emphasise the importance of interactive effects and context-dependent responses when planning conservation management under human-induced rapid environmental change.

  • Migrating mule deer track green waves of spring forage

    Migratory mule deer in Wyoming closely time their movements to track the spring green-up, providing evidence of an underappreciated foraging benefit of migration, according to a study by University of Wyoming and U.S. Geological Survey scientists at the Wyoming Cooperative Fish and Wildlife Research Unit.

  • Wind Turbines Affect Behavior of Desert Tortoise Predators

    How a wind energy facility is designed can influence the behavior of animal predators and their prey, according to a recent study published in The Journal of Wildlife Management by researchers at the University of California, Davis, and the U.S. Geological Survey.

    Scientists placed motion-activated cameras facing the entrances of 46 active desert tortoise burrows in a wind energy facility near Palm Springs, California. Video recordings showed that visits to burrows from five predators -- bobcats, gray foxes, coyotes, black bears and western spotted skunks -- increased closer to dirt roads, and decreased closer to wind turbines.
