  • Bacterioplankton: Taking their vitamins
    on October 17, 2018 at 4:44 pm

    New research finds that more bacterioplankton utilize vitamin B1 or B1 precursors from their environment than synthesize their own. The researchers also found that B1 availability can directly limit bacterioplankton growth, which could have larger impacts on aquatic microbial food webs, as well as energy and nutrient exchange.

  • Moss rapidly detects, tracks air pollutants in real time
    on October 17, 2018 at 3:10 pm

    Moss, one of the world's oldest plants, is surprisingly in tune with the atmosphere around it. Now scientists report that they have found a simple and inexpensive way to detect air pollutants, specifically sulfur dioxide, in real time based on subtle changes in moss leaves. The discovery could rapidly alert authorities to potentially dangerous alterations in air quality using a sustainable, natural plant sensor. […]

  • A selfish gene makes mice into migrants
    on October 16, 2018 at 3:01 pm

    House mice carrying a specific selfish supergene move from one population to another much more frequently than their peers. This finding shows for the first time that a gene of this type can influence animal migratory behavior. It could help in dealing with invasive plagues transmitted by mice. […]

  • Mammals cannot evolve fast enough to escape current extinction crisis
    on October 15, 2018 at 7:44 pm

    The sixth mass extinction is underway, this time caused by humans. A team of researchers have calculated that species are dying out so quickly that nature's built-in defense mechanism, evolution, cannot keep up. If current conservation efforts are not improved, so many mammal species will become extinct during the next five decades that nature will need 3-5 million years to recover to current biodiversity levels. And that's a best-case scenario. […]

  • Polio: Environmental monitoring will be key as world reaches global eradication
    on October 15, 2018 at 7:06 pm

    Robust environmental monitoring should be used as the world approaches global eradication of polio, say researchers who recently studied the epidemiology of the 2013 silent polio outbreak in Rahat, Israel. […]

  • PPR virus poses threat to conservation
    on October 15, 2018 at 5:29 pm

    Researchers have reviewed the threat of the virus peste des petits ruminants (PPR) to conservation. […]

  • Potential benefits of wildlife-livestock coexistence in East Africa
    on October 15, 2018 at 3:35 pm

    A study of 3,588 square kilometers of privately owned land in central Kenya offers evidence that humans and their livestock can, in the right circumstances, share territory with zebras, giraffes, elephants and other wild mammals -- to the benefit of all. […]

  • Quantifying evolutionary impacts of humans on the biosphere is harder than it seems
    on October 12, 2018 at 3:02 pm

    Are human disturbances to the environment driving evolutionary changes in animals and plants? A new study finds that, on average, human disturbances don't appear to accelerate the process of natural selection. While the finding may seem reassuring, this unexpected pattern could reflect the limited number of species for which data were available. […]

  • Tropical moths in the mountains are larger
    on October 12, 2018 at 3:01 pm

    Researchers have measured more than 19,000 tropical moths from 1,100 species to find out whether their size varies with elevation. The researchers found clear patterns: moths increase in size significantly at higher elevations. […]

  • Clues from a Somalian cavefish about modern mammals' dark past
    on October 11, 2018 at 3:24 pm

    After millions of years living in darkness, a species of blind cavefish has lost an ancient system of DNA repair. That DNA repair system, found in organisms including bacteria, fungi, plants, and most other animals, harnesses energy from visible light to repair DNA damage induced by ultraviolet (UV) light. The findings are intriguing in part because only placental mammals were previously known to lack this system. […]

  • Shrimp talent quest finds a winner
    on October 11, 2018 at 2:36 pm

    Shrimp help keep fish clean -- and scientists have identified the 'cleaner shrimp' with the most talent for reducing parasites and chemical use in farmed fish. […]

  • New study helps explain recent scarcity of Bay nettles
    on October 10, 2018 at 8:47 pm

    A new, long-term study of how environmental conditions affect the abundance and distribution of jellyfish in the nation's largest estuary helps explain the widely reported scarcity of sea nettles within Chesapeake Bay during the past few months and raises concerns about how a long-term continuation of this trend might harm Bay fisheries as climate continues to warm. […]

  • Understanding water's role in antibiotic resistance emergence and dissemination in Africa
    on October 10, 2018 at 4:49 pm

    Greater access to antibiotic drugs, together with their misuse and overuse, has accelerated the emergence of antibiotic resistant bacteria worldwide. A new study now suggests that surface water dynamics are a crucial contributor to this growing global health concern. […]

  • Evolutionary 'arms race' -- how dolphins and whales fight disease threats
    on October 10, 2018 at 1:36 pm

    A groundbreaking study reveals how dolphins, whales and other cetaceans compete for survival in an evolutionary 'arms race' with changing pathogenic threats like mercury and brevotoxin (e.g. Red Tide). Researchers show that cetaceans use several strategies for success in this race. They have developed tools to help wildlife managers and health professionals assess disease risk from the perspective of how individual animals are engineered to recognize the molecules of microorganisms in the environment and launch an immune response. […]

  • Crowd-sourced data wins protection for endangered tricolored blackbird
    on October 9, 2018 at 9:56 pm

    Researchers used eBird data to convince California to list the Tricolored Blackbird as endangered. […]

  • Becoming promiscuous to ensure reproduction
    on October 9, 2018 at 3:36 pm

    Females of a socially monogamous passerine, the Japanese great tit (Parus minor), become more promiscuous after hatchings fail in the first breeding attempt -- apparently attempting to ensure successful reproduction. […]

  • New knowledge about retrovirus-host coevolution
    on October 9, 2018 at 2:24 pm

    Retroviruses have colonized vertebrate hosts for millions of years by inserting their genes into host genomes, enabling their inheritance through generations as endogenous retroviruses (ERVs). Researchers now provide new knowledge about the long-term associations of retroviruses and their hosts by studying ERV variation and segregation in wild and domestic rabbit populations. […]

  • Genes responsible for difference in flower color of snapdragons identified
    on October 8, 2018 at 10:33 pm

    Snapdragons are tall plants, and flower in a range of colors. In Spain, where snapdragons grow wild, these flower colors show a remarkable pattern: areas of magenta and yellow blooming flowers are separated by just a two kilometer long stretch in which flower colors mix. Scientists have investigated the causes of this pattern and identified the genes responsible for flower color difference from DNA sequence data. […]

  • Small-brained female guppies aren't drawn to attractive males
    on October 8, 2018 at 3:44 pm

    Female guppies with smaller brains can distinguish attractive males, but they don't recognize them as being more appealing or choose to mate with them, according to a new study. The study adds weight to the link between mate preference and cognitive ability. […]

  • Underestimating combined threats of deforestation and wildlife trade will push Southeast Asian birds
    on October 7, 2018 at 12:40 pm

    The combined impact of deforestation and wildlife exploitation on bird numbers is severely underestimated and could lead to some species becoming extinct, a study has found. […]
