Multiple ecosystems in hot water after marine heatwave surges across the Pacific //www.koonmotors.com/releases/2023/07/230713142059.htm Rising ocean temperatures are sweeping the seas, breaking records and creating problematic conditions for marine life. Unlike heatwaves on land, periods of abrupt ocean warming can surge for months or years. Around the world these 'marine heatwaves' have led to mass species mortality and displacement events, economic declines and habitat loss. New research reveals that even areas of the ocean protected from fishing are still vulnerable to these extreme events fueled by climate change. Thu, 13 Jul 2023 14:20:59 EDT //www.koonmotors.com/releases/2023/07/230713142059.htm Air pollution particles may be cause of dramatic drop in global insect numbers //www.koonmotors.com/releases/2023/07/230712124747.htm Researchers report that an insect's ability to find food and a mate is reduced when their antennae are contaminated by particulate matter from industry, transport, bushfires, and other sources of air pollution. 结婚12 7月2023 12:47:47 EDT //www.koonmotors.com/releases/2023/07/230712124747.htm Belief in animals' capacity for emotion linked to better health and welfare //www.koonmotors.com/releases/2023/07/230712124655.htm Working equids whose owners believe in their capacity to feel emotion have significantly better health and welfare outcomes than those whose owners do not, according to new research. 结婚12 7月2023 12:46:55 EDT //www.koonmotors.com/releases/2023/07/230712124655.htm Tiny fish surprise scientists in 'volunteer's dilemma' //www.koonmotors.com/releases/2023/07/230712011610.htm Tiny fish called Trinidadian guppies have surprised scientists when faced with the so-called 'volunteer's dilemma'. 结婚12 7月2023 01:16:10 EDT //www.koonmotors.com/releases/2023/07/230712011610.htm Exposure to neurotoxic rodenticide bromethalin in birds of prey //www.koonmotors.com/releases/2023/07/230711133304.htm In 2020, Tufts Wildlife Clinic Director Maureen Murray, V03, published a study that showed 100% of red-tailed hawks tested at the clinic were positive for exposure to anticoagulant rodenticides (ARs). Such exposure occurs when these chemicals are used to kill mice or rats, which eat the poison, and the birds eat the poisoned prey. Now, another type of rodenticide -- a neurotoxicant called bromethalin -- also can bioaccumulate in birds of prey.

Mon, 10 Jul 2023 18:05:27 EDT //www.koonmotors.com/releases/2023/07/230710180527.htm Caterpillar venom study reveals toxins borrowed from bacteria //www.koonmotors.com/releases/2023/07/230710180448.htm Researchers have found toxins in the venom of asp caterpillars are completely different to anything they have seen before in insects. Toxins in the caterpillar venom punch holes in cells the same way as toxins produced by disease-causing bacteria such as E. coli and Salmonella. Venoms are rich sources of new molecules that could be developed into medicines of the future, pesticides, or used as scientific tools. Mon, 10 Jul 2023 18:04:48 EDT //www.koonmotors.com/releases/2023/07/230710180448.htm Study shows same-sex sexual behavior is widespread and heritable in macaque monkeys //www.koonmotors.com/releases/2023/07/230710113924.htm Observations of a wild colony of macaques over three years show same-sex sexual behavior among males is widespread and may be beneficial.

Mon, 10 Jul 2023 11:38:24 EDT //www.koonmotors.com/releases/2023/07/230710113824.htm Beak shape can predict nest material use in the world's birds //www.koonmotors.com/releases/2023/07/230709202503.htm The material a bird selects for its nest depends on the dimensions of its beak, according to researchers. Sun, 09 Jul 2023 20:25:03 EDT //www.koonmotors.com/releases/2023/07/230709202503.htm Human-made materials in nests can bring both risks and benefit for birds //www.koonmotors.com/releases/2023/07/230709202455.htm We all discard a huge amount of plastic and other human-made materials into the environment, and these are often picked up by birds. New research has shown that 176 bird species around the world are now known to include a wide range of anthropogenic materials in their nests. This material found in birds' nests can be both beneficial and harmful say researchers. Sun, 09 Jul 2023 20:24:55 EDT //www.koonmotors.com/releases/2023/07/230709202455.htm Food labels offer consumer choices but also confusion about animal welfare //www.koonmotors.com/releases/2023/07/230707111640.htm Animal-based food products often come packaged in a wide array of information labels, including organic, natural, grass-fed, humanely raised and pasture-raised. But it's typically up to the consumer to do their homework and figure out what these different claims mean. Fri, 07 Jul 2023 11:16:40 EDT //www.koonmotors.com/releases/2023/07/230707111640.htm Global diet study challenges advice to limit high-fat dairy foods //www.koonmotors.com/releases/2023/07/230706231355.htm Unprocessed red meat and whole grains can be included or left out of a healthy diet, according to a study conducted in 80 countries across all inhabited continents. Diets emphasizing fruit, vegetables, dairy (mainly whole-fat), nuts, legumes and fish were linked with a lower risk of cardiovascular disease (CVD) and premature death in all world regions. The addition of unprocessed red meat or whole grains had little impact on outcomes. Thu, 06 Jul 2023 23:13:55 EDT //www.koonmotors.com/releases/2023/07/230706231355.htm Not eating enough of these six healthy foods is associated with higher cardiovascular disease and deaths globally //www.koonmotors.com/releases/2023/07/230706231347.htm Previous and similar research has focused on Western countries and diets that combined harmful, ultra-processed foods with nutrient-dense foods. This research was global in scope and focused on foods commonly considered to be healthy. Researchers derived a diet score from PHRI's ongoing, large-scale global Prospective Urban and Rural Epidemiological (PURE) study, then replicated that in five independent studies to measure health outcomes in different world regions and in people with and without prior CVD. Thu, 06 Jul 2023 23:13:47 EDT //www.koonmotors.com/releases/2023/07/230706231347.htm Policymakers should consider animal welfare in decisions //www.koonmotors.com/releases/2023/07/230706152651.htm Incorporating animal welfare into policymaking may improve policy and practice, according to new research. The article notes that animal welfare rarely is considered during policymaking, explains why current tools make it difficult to incorporate the well-being of animals into public policy and identifies methods for remedying these issues. Thu, 06 Jul 2023 15:26:51 EDT //www.koonmotors.com/releases/2023/07/230706152651.htm Discovery of 500-million-year-old fossil reveals astonishing secrets of tunicate origins //www.koonmotors.com/releases/2023/07/230706124616.htm Researchers describe a 500 million-year-old tunicate fossil species. The study suggests that the modern tunicate body plan was already established soon after the Cambrian Explosion. Thu, 06 Jul 2023 12:46:16 EDT //www.koonmotors.com/releases/2023/07/230706124616.htm Marine heat waves caused mass seabird die-offs, beach surveys show //www.koonmotors.com/releases/2023/07/230706124544.htm New research uses data collected by coastal residents along beaches from central California to Alaska to understand how seabirds have fared in recent decades. The paper shows that persistent marine heat waves lead to massive seabird die-offs months later. Thu, 06 Jul 2023 12:45:44 EDT //www.koonmotors.com/releases/2023/07/230706124544.htm Fossils reveal how ancient birds molted their feathers -- which could help explain why ancestors of modern birds survived when all the other dinosaurs died //www.koonmotors.com/releases/2023/07/230705154016.htm Birds are the only group of dinosaurs that survived the asteroid-induced mass extinction 66 million years ago. But not all the birds alive at the time made it. Why the ancestors of modern birds lived while so many of their relatives died has been a mystery that paleontologists have been trying to solve for decades. Two new studies point to one possible factor: the differences between how modern birds and their ancient cousins molt their feathers. Wed, 05 Jul 2023 15:40:16 EDT //www.koonmotors.com/releases/2023/07/230705154016.htm Apex predator of the Cambrian likely sought soft over crunchy prey //www.koonmotors.com/releases/2023/07/230704200703.htm Biomechanical studies on the arachnid-like front 'legs' of an extinct apex predator show that the 2-foot (60-centimeter) marine animal Anomalocaris canadensis was likely much weaker than once assumed. One of the largest animals to live during the Cambrian, it was probably agile and fast, darting after soft prey in the open water rather than pursuing hard-shelled creatures on the ocean floor. Tue, 04 Jul 2023 20:07:03 EDT //www.koonmotors.com/releases/2023/07/230704200703.htm Warmer and murkier waters favor predators of guppies, study finds //www.koonmotors.com/releases/2023/07/230704200701.htm Changes in water conditions interact to affect how Trinidadian guppies protect themselves from predators, scientists have discovered. Tue, 04 Jul 2023 20:07:01 EDT //www.koonmotors.com/releases/2023/07/230704200701.htm World's most threatened seabirds visit remote plastic pollution hotspots //www.koonmotors.com/releases/2023/07/230704110939.htm 全球77种跟踪数据的分析petrel has revealed that a quarter of all plastics potentially encountered in their search for food are in remote international waters -- requiring international collaboration to address. Tue, 04 Jul 2023 11:09:39 EDT //www.koonmotors.com/releases/2023/07/230704110939.htm Birds raise fewer young when spring arrives earlier in a warming world //www.koonmotors.com/releases/2023/07/230703160005.htm A new study of North American songbirds finds that birds can't keep up with the earlier arrival of spring caused by climate change. As a result, they're raising fewer young. By the end of the 21st century, climate change will cause springlike weather to begin 25 days earlier, but birds will only breed about seven days earlier. That change could lead to an average reduction of 12% in breeding productivity for songbird species. Mon, 03 Jul 2023 16:00:05 EDT //www.koonmotors.com/releases/2023/07/230703160005.htm Counting Africa's largest bat colony //www.koonmotors.com/releases/2023/07/230703133110.htm Artificial intelligence and computer vision provide most accurate estimate yet. Mon, 03 Jul 2023 13:31:10 EDT //www.koonmotors.com/releases/2023/07/230703133110.htm New A.I. system can decode fruit fly behaviors: Why that's 'pivotal' for future human genetics research //www.koonmotors.com/releases/2023/07/230701135755.htm For more than a century, scientists have used fruit flies' simple genome and short lifespan to decode mysteries of genetic inheritance. Now a new machine-learning system can track fruit flies and interpret different behaviors. Sat, 01 Jul 2023 13:57:55 EDT //www.koonmotors.com/releases/2023/07/230701135755.htm Rising monkey and pig populations pose human disease risk //www.koonmotors.com/releases/2023/06/230630123229.htm Exploding populations of wild pigs and macaque monkeys in Southeast Asia are threatening native forests and disease outbreaks in livestock and people, according to new research. Fri, 30 Jun 2023 12:32:29 EDT //www.koonmotors.com/releases/2023/06/230630123229.htm Early birds of the future: earlier, but still too late? //www.koonmotors.com/releases/2023/06/230630123217.htm Birds need to adapt to climate change, but evolution is a slow process. Model species such as the great tit are an indispensable yardstick for our ability to predict the impact of climate change on nature. Using innovative methods, a team from the Netherlands Institute of Ecology (NIOO-KNAW) took a sneak peek into the birds' future. Fri, 30 Jun 2023 12:32:17 EDT //www.koonmotors.com/releases/2023/06/230630123217.htm Static electricity attracts ticks to hosts //www.koonmotors.com/releases/2023/06/230630123213.htm Ticks can be attracted across air gaps several times larger than themselves by the static electricity that their hosts naturally accumulate, researchers have discovered. Fri, 30 Jun 2023 12:32:13 EDT //www.koonmotors.com/releases/2023/06/230630123213.htm Scientists discover clues to aging and healing from a squishy sea creature //www.koonmotors.com/releases/2023/06/230630123210.htm Insights into healing and aging by those who studied how a tiny sea creature regenerates an entire new body from only its mouth. The researchers sequenced RNA from Hydractinia symbiolongicarpus, a small, tube-shaped animal that lives on the shells of hermit crabs. Just as the Hydractinia were beginning to regenerate new bodies, the researchers detected a molecular signature associated with the biological process of aging, also known as senescence. Fri, 30 Jun 2023 12:32:10 EDT //www.koonmotors.com/releases/2023/06/230630123210.htm Virus-like transposons wage war on the species barrier //www.koonmotors.com/releases/2023/06/230629193248.htm Scientists have known for decades that genes can be transferred from one species to another, both in animals and plants. However, the mechanism of how such an unlikely event occurs remained unknown. Now, researchers identify a vector of horizontal gene transfer (HGT) in worms. The findings could lead to the discovery of further vectors of HGT in eukaryotes and might find applications in pathogen control. Thu, 29 Jun 2023 19:32:48 EDT //www.koonmotors.com/releases/2023/06/230629193248.htm A new species of mosquitoes found in Finland -- official count of species now at 44 //www.koonmotors.com/releases/2023/06/230629125737.htm The mosquito species Culex modestus has been found in Finland for the first time. In Southern Europe it is known to spread West Nile virus, but it is highly unlikely for the disease to occur in Finland. Culex modestus has become the 44th mosquito species found in Finland, and the northernmost record of the species in Europe. The previous findings closest to Finland, but further south, have been made in the Leningrad Province in Russia and in Skåne in Sweden. Thu, 29 Jun 2023 12:57:37 EDT //www.koonmotors.com/releases/2023/06/230629125737.htm Birds and honey badgers could be cooperating to steal from bees in parts of Africa //www.koonmotors.com/releases/2023/06/230629125725.htm The honeyguide bird loves beeswax, but needs help breaking open bees' nests to get it. So it shows a honey badger the way to the nest, who rips it open and together they share the rewards. Or so the story goes. Thu, 29 Jun 2023 12:57:25 EDT //www.koonmotors.com/releases/2023/06/230629125725.htm A seed survival story: How trees keep 'friends' close and 'enemies' guessing //www.koonmotors.com/releases/2023/06/230629125706.htm A new study that included millions of tree-year observations worldwide for the first time documents and analyzes the intricate balance between seed defense and dispersal by forest trees at a global scale. Thu, 29 Jun 2023 12:57:06 EDT //www.koonmotors.com/releases/2023/06/230629125706.htm Worm named after a comedian impacting spiny lobster reproduction and could threaten a lucrative fishery //www.koonmotors.com/releases/2023/06/230628201436.htm A species of nemertean worm discovered by a marine biologist five years ago affects the reproductive performance of Caribbean spiny lobsters, a critical species in the Caribbean Sea and the Gulf of Mexico. Antonio Baeza, an associate professor in the Department of Biological Sciences, discovered the new worm while researching parental behaviors of the spiny lobster Panulirus argus in the Florida Keys. New research shows the worm affected embryo mortality, fecundity and reproductive output in brooding females.

This work will aid monitoring the health of dolphin populations and inform timely conservation efforts. Wed, 28 Jun 2023 20:14:30 EDT //www.koonmotors.com/releases/2023/06/230628201430.htm Songbird study shows one hit wonder has to change his tune to attract a mate //www.koonmotors.com/releases/2023/06/230628130500.htm Over two years, researchers recorded and analyzed 7,000 songs of wild blue tits breeding in closely monitored nest boxes. They devised an experiment which involved playing song recordings to receptive females and discovered that male vocal consistency -- repeating the same pattern of notes with high precision -- was the key song feature that made females sexually excited. Wed, 28 Jun 2023 13:05:00 EDT //www.koonmotors.com/releases/2023/06/230628130500.htm Boom! Detecting gregarious goliath groupers using their low-frequency pulse sounds //www.koonmotors.com/releases/2023/06/230628130418.htm From growls to booms, whales, fish and crustaceans all produce sounds. Selecting the gregarious Goliath grouper, researchers deployed a novel automated detector and localization model to find underwater marine organisms using their low-frequency pulse sounds. Although passive acoustics has shed light on fish habitat preference as well as their movements, no studies have been able to illustrate their detailed behavior, until now. Classifying sounds produced by fish will help to understand how they respond to environmental changes and anthropogenic disturbances. Wed, 28 Jun 2023 13:04:18 EDT //www.koonmotors.com/releases/2023/06/230628130418.htm Undergrad-driven project reveals drought's effects on painted turtles //www.koonmotors.com/releases/2023/06/230628130412.htm A projected rise in droughts could muddy the waters for painted turtles and some fellow freshwater-dwelling reptiles, says 11 years of data collected by 50-plus undergraduates. Two recent studies based on the data suggest that drought can lower the survival odds, slow the growth and even skew the ratio of female-to-male painted turtles inhabiting the ponds of the Cornhusker State. Those outcomes emerged despite the water level of a sampled pond in southwestern Nebraska remaining relatively steady throughout the observed periods of drought. Wed, 28 Jun 2023 13:04:12 EDT //www.koonmotors.com/releases/2023/06/230628130412.htm Why hellbenders are disappearing //www.koonmotors.com/releases/2023/06/230628130127.htm The gigantic, slimy salamanders known as hellbenders, once the apex predators of many freshwater streams, have been in decline for decades. A study has determined that in deforested areas, hellbender fathers are far more likely to eat their entire brood than in areas that still have lush foliage. Wed, 28 Jun 2023 13:01:27 EDT //www.koonmotors.com/releases/2023/06/230628130127.htm A jaw-dropping conundrum: Why do mammals have a stiff lower jaw? //www.koonmotors.com/releases/2023/06/230627225225.htm The lower jaws of lizards, birds, fish and even dinosaurs are comprised of multiple bones per side. Yet mammals diverged from all other vertebrates and settled on just one bone, repurposing the extra bones into a more elaborate inner ear, perhaps the better to hear. The single bone per side, fused in primates into one jawbone, makes the jaw more rigid. A paleontologist asks, Did the stiffer, rigid jaw make mammals more successful? Tue, 27 Jun 2023 22:52:25 EDT //www.koonmotors.com/releases/2023/06/230627225225.htm Boy fly meets girl fly meets AI: Training an AI to recognize fly mating identifies a gene for mating positions //www.koonmotors.com/releases/2023/06/230627225217.htm A research group has developed a new system to detect mating in fruit flies using artificial intelligence. They used the system to determine how fruit flies use mechanical stimuli during mating to maintain an effective mating position. When they tested their theory by inhibiting a key stimulus, the males used an off-center, ineffective mating posture. Tue, 27 Jun 2023 22:52:17 EDT //www.koonmotors.com/releases/2023/06/230627225217.htm European bird communities move to cooler areas, but mountain ranges and coastlines 'control the traffic' //www.koonmotors.com/releases/2023/06/230627225135.htm A recent study shows that European bird communities have shifted northeastward in the past 30 years. These shifts are faced with obstacles such as mountain ranges and coastlines. Overall, bird communities are moving towards cooler areas but not fast enough to keep up with increasing temperatures.

Mon, 26 Jun 2023 16:41:58 EDT //www.koonmotors.com/releases/2023/06/230626164158.htm Research questions value of sagebrush control in conserving sage grouse //www.koonmotors.com/releases/2023/06/230626164153.htm Sagebrush reduction strategies, including mowing and herbicide application, are often employed to enhance habitat for the greater sage grouse and other sagebrush-dependent species. Mon, 26 Jun 2023 16:41:53 EDT //www.koonmotors.com/releases/2023/06/230626164153.htm Megalodon was no cold-blooded killer //www.koonmotors.com/releases/2023/06/230626164144.htm How the megalodon, a shark that went extinct 3.6 million years ago, stayed warm was a matter of speculation among scientists. Using an analysis of tooth fossils from the megalodon and other sharks of the same period, a study suggests the animal was able to maintain a body temperature well above the temperature of the water in which it lived. The finding could help explain why the megalodon went extinct during the Pliocene Epoch. Mon, 26 Jun 2023 16:41:44 EDT //www.koonmotors.com/releases/2023/06/230626164144.htm Human impact on wildlife even in protected areas //www.koonmotors.com/releases/2023/06/230626163159.htm The largest long-term standardized camera-trap survey to date finds that human activity impacts tropical mammals living in protected areas and sheds light on how different species are affected based on their habitat needs and anthropogenic stressors.

This finding may explain why many animals besides turtles have temperature-dependent sex determination and why the system persists, despite seeming like a risky strategy. It may also provide a troubling glimpse of what could lie ahead in a warming world.

That means eukaryotes are, in the parlance of evolutionary biologists, a 'well-nested clade' within Asgard archaea, similar to how birds are one of several groups within a larger group called dinosaurs, sharing a common ancestor.

Sea lice are parasitic copepods (small crustaceans) found in many fresh and saltwater habitats, and have been implicated in the decline of wild salmon populations. The research sheds greater light on the types of viruses being carried by sea lice, and how the viruses and host are interacting.

More often than you think //www.koonmotors.com/releases/2023/06/230622142345.htm Animals that eat fruit or sip nectar often ingest alcohol because naturally occurring yeasts turning sugar into ethanol. But how do animals feel about that? A new study details an experiment to determine whether hummingbirds are turned off by alcohol in sugar water. At 1% by volume, no. At 2% by volume, they consume much less. The implication is that hummingbirds have adjusted to small amounts of alcohol likely present in flowers and backyard feeders.

The new study suggests that the butterflies with more white spots are more successful at reaching their long-distance wintering destination. Although it's not yet clear how the spots aid the species' migration, it's possible that the spots change airflow patterns around their wings.

Researchers show how microscopic Caenorhabditis elegans worms can use electric fields to 'jump' across Petri plates or onto insects, allowing them to glide through the air and attach themselves, for example, onto naturally charged bumblebee chauffeurs. 结婚,2023年6月21日12:10:38美国东部时间 //www.koonmotors.com/releases/2023/06/230621121038.htm Caribbean seagrasses provide services worth $255B annually, including vast carbon storage, study shows //www.koonmotors.com/releases/2023/06/230621105442.htm Caribbean seagrasses provide about $255 billion in services to society annually, including $88.3 billion in carbon storage, according to a new study. The study has put a dollar value on the many services -- from storm protection to fish habitat to carbon storage -- provided by seagrasses across the Caribbean, which holds up to half the world's seagrass meadows by surface area and contains about one-third of the carbon stored in seagrasses worldwide.
