Published Certain frogs more sensitive to climate change, not protected
(via sciencedaily.com) Amphibians worldwide are affected by climate change and potentially one of the most threatened. Biologists found that some species of amphibians are more likely to be sensitive to climate change because they are not protected by state or federal regulations. The team determined that approximately 11 percent of anuran species are sensitive to climate change, but are not currently listed as at-risk either at the state, federal, or international levels.
Published Human-wildlife conflicts rising worldwide with climate change
(via sciencedaily.com) Scientists reveal that a warming world is increasing human-wildlife conflicts globally. They show that climate shifts can drive conflicts by altering animal habitats, the timing of events, wildlife behaviors and resource availability. It also showed that people are changing their behaviors and locations in response to climate change in ways that increase conflicts.
Published The rediscovery of an ethereal fairy lantern brightly illuminates their mysterious past
(via sciencedaily.com) After more than 30 years, botanists have rediscovered Thismia kobensis, a type of mysterious-looking rare plant commonly referred to as 'fairy lanterns'. Thismia kobensis was presumed extinct and the surprise rediscovery of this Japanese variety has illuminated hidden aspects of fairy lanterns that have puzzled and fascinated botanists for centuries.
Published Shrinking age distribution of spawning salmon raises climate resilience concerns
(via sciencedaily.com) By returning to spawn in the Sacramento River at different ages, Chinook salmon lessen the potential impact of a bad year and increase the stability of their population in the face of climate variability, according to a new study. Unfortunately, spawning Chinook salmon are increasingly younger and concentrated within fewer age groups, with the oldest age classes of spawners rarely seen in recent years. The new findings suggest changes in hatchery practices and fishery management could help restore the age structure of the salmon population and make it more resilient to climate change.
Published New study reveals biodiversity loss drove ecological collapse after the 'Great Dying'
(via sciencedaily.com) By exploring the stability and collapse of marine ecosystems during the Permian-Triassic mass extinction, researchers gain insights into modern biodiversity crisis.
Published Insect bite marks show first fossil evidence for plants' leaves folding up at night
(via sciencedaily.com) Plants can move in ways that might surprise you. Some of them even show 'sleep movements,' folding or raising their leaves each night before opening them again the next day. Now, researchers offer convincing evidence for these nightly movements, also known as foliar nyctinasty, in fossil plants that lived more than 250 million years ago.
Published Marine heatwaves decimate sea urchins, molluscs and more at Rottnest
(via sciencedaily.com) Researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as molluscs and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 per cent between 2007 and 2021.
Published Scientists unlock key to drought-resistant wheat plants with longer roots
(via sciencedaily.com) Growing wheat in drought conditions may be easier in the future. Researchers found the right number of copies of a specific group of genes can stimulate longer root growth, enabling wheat plants to pull water from deeper supplies.
Published Effort to help pollinators shows successes, limitations
(via sciencedaily.com) A three-year effort to conserve bee populations by introducing pollinator habitat in North Carolina agricultural areas showed some positive effects, as bee abundance and diversity increased in the studied areas. But results of a study examining the program's effectiveness also showed that the quality of the habitat played a key role in these positive effects, and that habitat quality could be impacted by the way the areas are maintained over time.
Published Malaria infection harms wild African apes
(via sciencedaily.com) Scientists conducted a study that reveals the first evidence of harm caused by malaria infection among wild African apes. They discovered that bonobo populations differ in a key immune trait depending on the presence of malaria infection. Infected populations have a higher frequency of an immune variant that protects against developing severe disease, a pattern that mirrors what is observed among human populations.
Published 'Antisocial' damselfish are scaring off cleaner-fish customers -- and this could contribute to coral reef breakdown
(via sciencedaily.com) 'Antisocial' damselfish are scaring off cleaner fish customers -- and this could contribute to coral reef breakdown. Damselfish have been discovered to disrupt 'cleaning services' vital to the health of reefs. And climate change may mean this is only likely to get worse.
Published A labyrinth lake provides surprising benefits for an endangered seal
(via sciencedaily.com) The endangered Saimaa ringed seal is an Ice Age relict living in the highly labyrinthine Lake Saimaa, Finland. The newly published work shows that although individual seals have greatly reduced genetic variation, the loss of variation has been complementary, preserving the adaptive potential of the whole population.
Published Urban ponds require attention to ensure biodiversity
(via sciencedaily.com) New research suggests aquatic plants can be utilized as a tool to enhance the co-existence between aquatic invertebrates and their fish predators in urban ponds.
Published 3D printing with bacteria-loaded ink produces bone-like composites
(via sciencedaily.com) Researchers have published a method for 3D-printing an ink that contains calcium carbonate-producing bacteria. The 3D-printed mineralized bio-composite is unprecedentedly strong, light, and environmentally friendly, with a range of applications from art to biomedicine.
Published Single gene causes sea anemone's stinging cell to lose its sting
(via sciencedaily.com) When scientists disabled a single regulatory gene in a species of sea anemone, a stinging cell that shoots a venomous miniature harpoon for hunting and self-defense shifted to shoot a sticky thread that entangles prey instead, according to a new study.
Published Sea stars able to consume kelp-eating urchins fast enough to protect kelp forests, research shows
(via sciencedaily.com) Researchers have provided the first experimental evidence that a species of endangered sea star protects kelp forests along North America's Pacific Coast by preying on substantial numbers of kelp-eating urchins.
Published As sea ice declines in the Arctic, bowhead whales are adjusting their migration patterns
(via sciencedaily.com) As sea ice declines in the Arctic, bowhead whales are staying north of the Bering Strait more frequently, a shift that could affect the long-term health of the bowhead population and impact the Indigenous communities that rely on the whales, a new study shows.
Published Diets rich in food from the ocean and freshwater sources can help address nutritional and environmental challenges
(via sciencedaily.com) Blue foods -- those that come from the ocean or freshwater environments -- have tremendous potential to help address several global challenges. With careful implementation of policies that leverage these foods, nations could get a boost on efforts to reduce nutritional deficits, lower disease risk, decrease greenhouse gas emissions and ensure resilience in the face of climate change.
Published Researchers put plant protein mechanism into bacteria to help move forward 50 years of effort
(via sciencedaily.com) Researchers have added components of plant chloroplasts to bacteria. This feat, 50 years in the making, allows them to analyze the proteins in greater detail in order to improve Rubisco, and eventually photosynthesis.
Published Climate 'spiral' threatens land carbon stores
(via sciencedaily.com) The world's forests are losing their ability to absorb carbon due to increasingly 'unstable' conditions caused by humans, a landmark study has found.
