Published The waxy surface protecting plants might hold the key to developing stronger crops
(via sciencedaily.com) Original source Researchers have discovered that the waxy protective barrier around plants might play a role in sending chemical signals to other plants and insects.
Published how far can the wind can carry a plant's seeds? New model
(via sciencedaily.com) Original source Playing an essential foundational role in an ecosystem, plants contribute to the well-being of human health by helping create resources like food and medicine. Therefore, to better understand how plants can maintain resiliency in the face of challenges like climate change, researchers recently developed an innovative mathematical model that can provide fast and reliable predictions of how far wind can carry a plant's seeds.
Published Small marine creatures swimming in plastic chemicals not reproducing
(via sciencedaily.com) Original source Plastic waste in the water might be stopping -- or interrupting -- some shrimp-like creatures from reproducing. In a unique study, the ability of 'shrimp like' creatures to reproduce successfully was found to be compromised by chemicals found in everyday plastics.
Published Twin research indicates that a vegan diet improves cardiovascular health
(via sciencedaily.com) Original source A recent trial of identical twins comparing vegan and omnivore diets found that a vegan diet improves overall cardiovascular health.
Published This 'gross' mixture has big benefits for the study of bacteria
(via sciencedaily.com) Original source Researchers have discovered that growing bacteria on agar mixed with organs is an efficient and effective way to study infectious pathogens.
Published Identifying Australia's most elusive birds
(via sciencedaily.com) Original source Scientists have analyzed more than 3.8 million volunteer hours of birdwatching data to identify Australia's most elusive species.
Published Unknown animals were leaving bird-like footprints in Late Triassic Southern Africa
(via sciencedaily.com) Original source Ancient animals were walking around on bird-like feet over 210 million years ago, according to a new study.
Published Bees are still being harmed despite tightened pesticide regulations
(via sciencedaily.com) Original source A new study has confirmed that pesticides, commonly used in farmland, significantly harm bumblebees one of the most important wild pollinators. In a huge study spanning 106 sites across eight European countries, researchers have shown that despite tightened pesticide regulations, far more needs to be done.
Published Vulnerability of England's only resident bottlenose dolphins
(via sciencedaily.com) Original source New research has provided a detailed examination of England's bottlenose dolphin population's existence and the challenges it faces from human activities and environmental factors on a daily basis.
Published The venom preceded the stinger: Genomic studies shed light on the origins of bee venom
(via sciencedaily.com) Original source Bees, wasps and ants belong to the Hymenoptera order and inject a whole cocktail of venomous ingredients when they sting. Despite their tremendous ecological and economic importance, little was previously known about the origins of their venom. Through extensive genomic studies, a team of researchers has now discovered that typical venomous components were already present in the earliest ancestors of Hymenoptera and must therefore have evolved before the stingers of bees and other insects. What's more, and contrary to previous assumptions, the gene for the venom melittin is found solely in bees.
Published Landscape dynamics determine the evolution of biodiversity on Earth
(via sciencedaily.com) Original source A landmark study into the geological timescale distribution of sediment and nutrients over 500 million years shows that species biodiversity on Earth is driven by landscape dynamics.
Published Fish ecologist's research indicates need to conserve iconic migratory snook in Mexico
(via sciencedaily.com) Original source Biologists investigated the snook’s almost 400-mile migration up into the rainforest habitat of the Usumacinta River. They have found that the snook, which connect aquatic food webs and support fisheries, spawn and start their lives in coastal nursery habitats before moving into river habitats that offer an array of food resources.
Published Pioneering research method reveals bluefin tuna's fate
(via sciencedaily.com) Original source The Mediterranean spawning grounds of Bluefin tuna -- the largest tuna and one of the most powerful fish in the sea -- are under threat, due to rising sea temperatures. A pioneering research method to decode bluefin 'otoliths' (a stony tissue found in their ear) has determined the threshold sea temperature at which bluefin thrive to be 28 degrees Celsius.
Published Fish IgM structure sheds light on antibody evolution
(via sciencedaily.com) Original source Researchers have analyzed the antibody Immunoglobulin M in rainbow trout to shed some light on why these proteins may have evolved over time.
Published Vampire bats make northward flight seeking stable climates
(via sciencedaily.com) Original source A new article predicts that vampire bats -- currently only found in Mexico and Central and South America -- are on the move, with the United States being a viable home in 27 years.
Published Casas del Turuñuelo, a site of repeated animal sacrifice in Iron Age Spain
(via sciencedaily.com) Original source The Iron Age site of Casas del Turuñuelo was used repeatedly for ritualized animal sacrifice, according to a multidisciplinary study.
Published How do temperature extremes influence the distribution of species?
(via sciencedaily.com) Original source As the planet gets hotter, animal and plant species around the world will be faced with new, potentially unpredictable living conditions, which could alter ecosystems in unprecedented ways. A new study investigates the importance of temperature in determining where animal species are currently found to better understand how a warming climate might impact where they might live in the future.
Published Skunks' warning stripes less prominent where predators are sparse, study finds
(via sciencedaily.com) Original source Striped skunks are less likely to evolve with their famous and white markings where the threat of predation from mammals is low, scientists have discovered.
Published First comprehensive look at effects of 2020-2021 California megafires on terrestrial wildlife habitat
(via sciencedaily.com) Original source In 2020 and 2021, California experienced fire activity unlike anything recorded in the modern record. When the smoke cleared, the amount of burned forest totaled ten times more than the annual average going back to the late 1800s. We know that wildlife in western forests evolved with changing habitat and disturbances like wildfire. Each species responds differently, some benefiting from openings, others losing critical habitat. What we don't know is how increasing fire severity at large scales is impacting their habitat and survival, because many species are not adapted to these types of 'megafires.'
Published Curators and cavers: How a tip from a citizen scientist led to deep discoveries in Utah's caves
(via sciencedaily.com) Original source Scientists and colleagues from Utah's caving community have published the first research from their collaborative fieldwork effort deep in Utah's caves. The journal's feature article reveals why caves make such compelling research archives; what was uncovered in Boomerang Cave in northern Utah; why skeletal remains provide new access to hard-to-get data from the recent past; and offers a new zoological baseline for mammalian changes in an alpine community.
