  • Strong evidence shows Sixth Mass Extinction of global biodiversity in progress
    on January 14, 2022 at 12:49 am

    The history of life on Earth has been marked five times by events of mass biodiversity extinction caused by extreme natural phenomena. Today, many experts warn that a Sixth Mass Extinction crisis is underway, this time entirely caused by human activities. A comprehensive assessment of evidence of this ongoing extinction event was recently published.

  • New research advocates a basic strategy for native fish recovery: Access to water
    on January 13, 2022 at 8:14 pm

    Rivers need water -- a fact that may seem ridiculously obvious, but in times of increasing water development, drought, and climate change, the quantity of natural streamflow that remains in river channels is coming into question, especially in the Colorado River basin. Newly published research poses a tough question in these days of falling reservoir levels and high-stakes urban development: whether the continued development of rivers for water supply can be balanced with fish conservation.

  • Lost birds and mammals spell doom for some plants
    on January 13, 2022 at 8:13 pm

    In one of the first studies of its kind, researchers have gauged how biodiversity loss of birds and mammals will impact plants' chances of adapting to human-induced climate warming.

  • What will it take to save the regent honeyeater from extinction?
    on January 13, 2022 at 4:15 pm

    New research shows unless conservation actions are urgently stepped up, one of our most beautiful songbirds, the regent honeyeater, will be extinct within 20 years.

  • Citizen science data from Berlin show that urban areas can be a refuge for bats, if certain conditions are met
    on January 13, 2022 at 4:15 pm

    Urbanization is a notable threat to bat populations all over the world, especially through artificial light and the reduction of habitat and food supply. If certain conditions are met, some spaces within metropolitan areas can be suitable for bats, so managing these spaces appropriately could contribute to bat conservation. With the help of more than 200 citizen scientists in Berlin, a team of scientists examined these conditions and investigated how they affect the abundance and distribution of bat species. They conclude that maintaining a low level of artificial light at night is important for all bats in cities. In addition, access to vegetation and water bodies is essential for many of them.

  • New conservation tool calculates the optimal time to spend researching a habitat before protecting it
    on January 13, 2022 at 2:21 pm

    Deciding when to stop learning and take action is a common, but difficult decision in conservation. Using a new method, this trade-off can be managed by determining the amount of time to spend on research at the outset.

  • Predator species help to buffer climate change impacts on biodiversity
    on January 12, 2022 at 5:15 pm

    Predator species may buffer the negative impacts of climate change by mitigating against the loss of biodiversity, according to new research. The team of scientists behind the discovery say their findings underline the importance of conserving biodiversity, and top predators in particular, and highlight the potential for species extinctions to worsen the effects of climate change on ecosystems.

  • Ecological tradeoff? Utility-scale solar energy impedes endangered Florida panthers
    on January 12, 2022 at 3:57 pm

    Reducing the energy industry's carbon footprint in the sunshine state is impeding a large carnivore's paw-print. A study is the first to document the effect of utility-scale solar energy (USSE) facilities in Peninsular Florida on both habitat suitability and connectivity for any large carnivore. The study examined 45 USSE facilities equaling 27,688 acres.

  • Researchers find concerns for animals tied to same habitats
    on January 11, 2022 at 8:36 pm

    While site fidelity may be beneficial for animals when environmental conditions don't change very fast, those benefits may not be realized in the ever-changing world dominated by humans, researchers have found through a review of scientific literature.

  • Researchers discover fossil of new species of pangolin in Europe
    on January 10, 2022 at 11:48 pm

    Deeper analysis of fossils from one of Eastern Europe's most significant paleontological sites has led to the discovery of a new species of pangolin, previously thought to have existed in Europe during the early Pleistocene but not confirmed until now.

  • New bacteria in UK waters as temperatures rise
    on January 10, 2022 at 3:32 pm

    Rising temperatures are causing a 'growing diversity' of Vibrio bacteria in the sea around the UK, new research shows.

  • Zoo air contains enough DNA to identify the animals inside
    on January 6, 2022 at 4:15 pm

    The air in a zoo is full of smells, from the fish used for feed to the manure from the grazing herbivores, but now we know it is also full of DNA from the animals living there. Two research groups have each published an independent proof-of-concept study showing that by sampling air from a local zoo, they can collect enough DNA to identify the animals nearby. This may prove to be a valuable, non-invasive tool to track biodiversity.

  • Solving the disappearance of bears and lions with ancient DNA
    on January 4, 2022 at 3:26 pm

    Researchers suggest a change in climate is the likely cause of the mysterious disappearance of ancient lions and bears from parts of North America for a thousand years or more prior to the last Ice Age.

  • Climate change, invasive species drive native trout declines
    on January 4, 2022 at 2:56 pm

    Researchers have found that climate change drives native trout declines by reducing stream habitat and facilitating the expansion of invasive trout species.

  • From giant elephants to nimble gazelles: Early humans hunted the largest available animals to extinction for 1.5 million years, study finds
    on December 21, 2021 at 3:27 pm

    A new study tracks the development of early humans' hunting practices over the last 1.5 million years -- as reflected in the animals they hunted and consumed. The researchers claim that at any given time early humans preferred to hunt the largest animals available in their surroundings, which provided the greatest quantities of food in return for a unit of effort.

  • Looking at factors that accelerate mass extinction in the fossil record as climate changes
    on December 21, 2021 at 3:27 pm

    The Late Devonian mass extinction (roughly 372 million years ago) was one of five mass extinctions in Earth's history, with roughly 75% of all species disappearing over its course. It happened in two 'pulses,' spaced about 800,000 years apart, with most of the extinctions happening in the second pulse. However, for one group of animals living in eastern North America, the first pulse dealt the deadlier blow.

  • California spotted owls benefit from forest restoration
    on December 17, 2021 at 8:19 pm

    Forest restoration treatments can reduce future fire severity and benefit populations of California spotted owls, even with temporary disruptions within owl habitats in the Sierra Nevada, CA.

  • Robots use fear to fight invasive fish
    on December 16, 2021 at 7:59 pm

    The invasive mosquitofish (Gambusia holbrooki) chews off the tails of freshwater fishes and tadpoles, leaving the native animals to perish while dining on other fishes' and amphibians' eggs. Researchers engineered a robot to scare mosquitofish away, revealing how fear alters its behavior, physiology, fertility -- and may help turn the tide against invasive species.

  • Marine life can cling together to buy time in the face of climate warming
    on December 16, 2021 at 7:58 pm

    Some marine species can help protect others from climate change by shielding them from heat, according to a new study.

  • Darwin’s finches forced to 'evolve'
    on December 15, 2021 at 1:05 am

    Spending time with offspring is beneficial to development, but it's proving lifesaving to Galápagos Islands Darwin's finches. A new study has found evidence Darwin's finch females that spend longer inside the nest can ward off deadly larvae of the introduced avian vampire fly, which otherwise enter and consume the growing chicks.
