  • Love vine sucks life from wasps, leaving only mummies
    on August 20, 2018 at 7:01 pm

    An evolutionary biologists have discovered a new trophic interaction -- the first example of a parasitic plant attacking a parasitic insect on a shared host plant. The find could point to new methods for controlling agricultural pests and perhaps fighting cancer. […]

  • California plain shows surprising winners and losers from prolonged drought
    on August 20, 2018 at 3:31 pm

    A long-term study has tracked how hundreds of species in the Carrizo Plain National Monument fared during the historic drought that struck California from 2012 to 2015. […]

  • Invasive plants: Scientists examine the relative impact of proximity to seed sources
    on August 17, 2018 at 4:53 pm

    A new study tackles an important, unresolved question in the biology of invasive plants. Which is most important to the establishment of new invasive communities -- proximity to seed sources, canopy disturbance, or soil disturbance? […]

  • Genetic differences in trees untouched by mountain pine beetles
    on August 16, 2018 at 7:31 pm

    A researcher has discovered that mountain pine beetles may avoid certain trees within a population they normally would kill due to genetics in the trees. […]

  • Female mosquitoes get choosy quickly to offset invasions
    on August 16, 2018 at 3:43 pm

    Certain female mosquitoes quickly evolve more selective mating behavior when faced with existential threats from other invasive mosquito species, with concurrent changes to certain genetic regions, according to new research. […]

  • Logging site slash removal may be boon for wild bees in managed forests
    on August 16, 2018 at 1:14 pm

    New research suggests the removal of timber harvest residue during harvesting may be a boon for wild bees, an important step toward better understanding the planet's top group of pollinators. […]

  • Frequent fires make droughts harder for young trees, even in wet eastern forests
    on August 15, 2018 at 7:44 pm

    Forests in the eastern United States may have had it easy compared to their western counterparts, with the intense, prolonged droughts and wildfires that have become typical out west in recent years. But as the climate changes over time, eastern forests are also likely to experience longer droughts. And although wildfires are comparatively rare, prescriptive fires are increasingly used in the east. How will these forests fare in the future? A new study provides answers. […]

  • Protecting trees from imported pests
    on August 15, 2018 at 12:59 pm

    New research unravels the dynamics of tree production, economics and variability in demand to show how to reduce the risks of importing such damaging forest pests and diseases as oak processionary moth and ash dieback. […]

  • Severe declines of mountain hares on Scottish grouse moors
    on August 14, 2018 at 2:14 pm

    Mountain hare numbers on moorlands in the eastern Highlands have declined to less than one per cent of their initial levels, according to a long-term scientific study. […]

  • Deep in the weeds: Using eDNA sequencing to survey pondweed diversity
    on August 10, 2018 at 5:26 pm

    Researchers have developed a protocol using environmental DNA (eDNA) to identify aquatic plant diversity, making ecological biodiversity surveys of these plant communities faster and less expensive. Their study on pondweeds -- an important bioindicator of aquatic ecosystem health -- allows researchers to overcome difficulties in monitoring and identification, and draw conclusions regarding plant diversity and water quality. eDNA is a rapidly emerging technique, but its use in aquatic habitats has been understudied. […]

  • Fresh insight into invasive plant that blights UK rivers
    on August 10, 2018 at 4:00 pm

    New research into the behavior of an invasive plant seen on riverbanks across the UK could help improve the management of the problem, experts have found. […]

  • Lichen is losing to wildfire, years after flames are gone
    on August 9, 2018 at 1:34 pm

    As increasingly hot and severe wildfires scorch the West, some lichen communities integral to conifer forests aren't returning, even years after the flames have been extinguished, according to a study from scientists at the University of California, Davis. […]

  • Effective method to control algae growth on Hawaiian coral reefs
    on August 8, 2018 at 11:36 pm

    Researchers have found a management approach that combining manual removal and outplanting native urchin was effective at reducing invasive, reef smothering macroalgae by 85 percent on a coral reef off O'ahu, Hawai'i. […]

  • For the first time, scientists are putting extinct mammals on the map
    on August 8, 2018 at 5:42 pm

    Researchers have produced the most comprehensive family tree and atlas of mammals to date, connecting all living and recently extinct mammal species (nearly 6,000 in total) and overturning many previous ideas about global patterns of biodiversity. The atlas shows where species occur today as well as where they would occur, if they had not been driven away or extinct. […]

  • Molecular details of sperm-egg fusion
    on August 7, 2018 at 6:49 pm

    By revealing the structure of proteins that enable sperm and egg to fuse to form zygotes in plant and protozoan species, the new study may aid in discovering the fusion process for humans, which remains a mystery. […]

  • Each tropical tree species specializes in getting the nutrients it needs
    on August 3, 2018 at 4:19 pm

    Researchers looking for general patterns in the way tropical trees capture nutrients were surprised to find that every species has its own way of getting the nutrients it needs. The concept of biodiversity extends to their behavior. […]

  • Tropical forest seeds use three strategies to survive
    on August 3, 2018 at 2:33 pm

    From tiny banana seeds to giant coconuts, it's tough for seeds to survive in tropical soils where they are under constant attack by fungi, bacteria, insects and animals. By understanding how seeds defend themselves, tropical biologists contribute to reforestation, crop management and sustainable agriculture in the tropics. […]

  • Abandoned farmlands enrich bird communities
    on August 3, 2018 at 2:33 pm

    Abandoned farmlands hold potential for the preservation of wetland and grassland birds as rehabilitation zones. […]

  • The fate of Arctic mosquitoes depends on habitat and access to blood meals
    on August 3, 2018 at 2:33 pm

    The future of Arctic mosquitoes (Aedes nigripes) in western Greenland depends on aquatic habitat and access to blood meals, according to a new study. The study found that female mosquitoes carrying eggs were most abundant near ponds, especially in areas frequented by animals such as caribou, birds and the Arctic hare. […]

  • Rebuilding the tree of life of freshwater macroinvertebrates in the European continent
    on August 3, 2018 at 2:33 pm

    Scientists analyzed how water macroinvertebrate species, such as beetles, mosquitos and dragonflies, evolved and diversified since their beginnings. With the analysis of the ecological features of about 6,600 European species, the researchers rebuilt the functional space they occupy. […]
