Published New study reveals the profound impact of forced separation between humans and their pets



Pet owners forced to be separated from their animals in crisis situations, including those who are victims of domestic violence, are suffering from a lack of support services needed to protect them.
Published Dragonfly wings used to study relationship between corrugated wing structure and vortex motions



Scientists undertook a study of dragonfly wings in order to better understand the relationship between a corrugated wing structure and vortex motions. They discovered that corrugated wings exhibit larger lift than flat wings.
Published West Nile virus emergence and spread in Europe found to be positively associated with agricultural activities



The spread of West Nile virus in Europe is strongly linked to agricultural activities, urbanization, and bird migration, according to new research.
Published Sparrows uniquely adapted to Bay Area marshes are losing their uniqueness



How does loss of habitat affect the animals still living there? A genetic study of saltwater-adapted Savannah sparrows around the San Francisco Bay Area shows that the 90% loss of tidal marsh habitat has led to more interbreeding with freshwater-adapted Savannah sparrows, diminishing their genetic adaptation to saltwater, such as enlarged kidneys and larger beak. This could lessen their ability to live in a saltwater habitat.
Published Microplastics may be accumulating rapidly in endangered Galápagos penguins' food web



Model predictions showed a rapid increase in microplastic accumulation and contamination across the penguins' prey organisms resulting in Galapagos penguin showing the highest level of microplastics per biomass, followed by barracuda, anchovy, sardine, herring, and predatory zooplankton.
Published Live animal transport regulations not 'fit for purpose', major international study finds



A 'fitness check' of regulations in five countries meant to protect animals during transportation, has deemed that they all fall short of fully protecting animals during transport. Findings from this interdisciplinary work involving animal welfare scientists and a law lecturer which compared animal transport rules designed to protect the billions of livestock that are transported on lengthy journeys in Australia, Canada, New Zealand, EU (including UK) and US, highlights serious failures.
Published Marine heat waves trigger shift in hatch dates and early growth of Pacific cod



Marine heat waves appear to trigger earlier reproduction, high mortality in early life stages and fewer surviving juvenile Pacific cod in the Gulf of Alaska, a new study shows. These changes in the hatch cycle and early growth patterns persisted in years following the marine heat waves, which could have implications for the future of Gulf of Alaska Pacific cod, an economically and culturally significant species.
Published New video camera system captures the colored world that animals see, in motion



A new camera system allows ecologists and filmmakers to produce videos that accurately replicate the colors that different animals see in natural settings.
Published Blue tit population booms with moths on the menu



Researchers found that years when moth numbers were up resulted in increased population growth for the blue tit.
Published Gulls swap natural for urban habitats, machine-learning study finds



The study is the first of its kind to compile a three-year dataset using a citizen science-based, opportunistic research method to include a large sample of gulls and other sub-Arctic birds in urban Alaska. The study provides a current snapshot of the habitat shift to an urban landscape.
Published New research into hedgehogs injured by robotic lawn mowers discovers a significant but solvable animal welfare and conservation problem



Scientists analyzed 370 documented cases of hedgehogs being injured (cut) by electric gardening tools in Germany. Almost half of the hedgehogs found between June 2022 and September 2023 did not survive the injuries. The data reveal a serious animal welfare and conservation issue for these specially protected animals, as most hedgehogs were only found hours or even days after the accidents.
Published Don't blame the sharks: Why more hooked tarpon are being eaten



In wave-making research, a team of biologists has quantified the rate at which great hammerhead sharks are eating Atlantic tarpon hooked by anglers at Bahia Honda, Florida -- one of the prime tarpon fishing spots in the Florida Keys.
Published Student discovers 200-million-year-old flying reptile



Gliding winged-reptiles were amongst the ancient crocodile residents of the Mendip Hills in Somerset, England, researchers at the have revealed.
Published Knowing what dogs like to watch could help veterinarians assess their vision



A veterinary ophthalmologist wanted to determine factors, including age and vision, that influence a dog's interest in interacting with video content. Ultimately, the goal of the study, which launched two years ago, was to support development of more sensitive ways to assess canine vision -- something that has been sorely lacking in veterinary medicine. The study found that dogs are most engaged when watching videos that feature other animals.
Published For this beetle, 'date night' comes every other day



Life on Earth runs on a 24-hour cycle as the planet turns. Animals and plants have built-in circadian clocks that synchronize metabolism and behavior to this daily cycle. But one beetle is out of sync with the rest of nature. A new study looks at a beetle with a unique, 48-hour cycle.
Published Scientists, farmers and managers work together to avoid the decline of the little bustard, an endangered steppe bird



The collaboration between scientists, farmers and managers is crucial to improve the protection of the little bustard, an endangered steppe-land bird in Spain due to human activity. The reduction of natural habitats, the increase in irrigation and the urbanization of the land have led to having less surface areas that guarantee the survival of this vulnerable species.
Published Why animals shrink over time explained with new evolution theory



The new theoretical research proposes that animal size over time depends on two key ecological factors.
Published Rain can spoil a wolf spider's day, too



Researchers found that wolf spiders can't signal others or perceive danger from predators as easily on rain-soaked leaves compared to dry ones. Even communicating with would-be mates is harder after it rains.
Published Tiny AI-based bio-loggers revealing the interesting bits of a bird's day



Researchers have developed a bio-logger for seabirds that enables long-term observation of rare behaviors. The bio-logger employs low-power depth sensors and accelerometers to identify rare behavior using a light-weight outlier detection model and records the behavior in a 5-min video. Observations using the bio-loggers on Streaked Shearwaters revealed novel aspects of head-shaking and foraging strategies. This approach will enable a wider range of animal behaviors in various environments to be observed.
Published Surprise discovery: For most animals, sperm quality does not reduce with age



In humans, male fertility and sperm fitness decline with age, but scientists have made the surprising discovery that this pattern is not consistent in other animals. The team assessed the results of 379 studies which covered a wide range of animals, including mammals, insects, birds, and fish.
