Marine heat waves trigger shift in hatch dates and early growth of Pacific cod      (via sciencedaily.com)     Original source 

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.

Gulls swap natural for urban habitats, machine-learning study finds      (via sciencedaily.com)     Original source 

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.

New research into hedgehogs injured by robotic lawn mowers discovers a significant but solvable animal welfare and conservation problem      (via sciencedaily.com)     Original source 

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.

Wobbling particles in the sky      (via sciencedaily.com)     Original source 

Tiny particles such as ice crystals or ash particles tend to oscillate as they settle through the atmosphere. In their experiments, the scientists were able to track non-spherical particles of size smaller than 1 millimeter with unprecedented accuracy. Their observations gave rise to a model which can help to refine prediction on air pollutants or weather forecasts.

Knowing what dogs like to watch could help veterinarians assess their vision      (via sciencedaily.com)     Original source 

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.

For this beetle, 'date night' comes every other day      (via sciencedaily.com)     Original source 

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.

Climate change linked to spread of diarrheal illness      (via sciencedaily.com)     Original source 

Temperature, day length and humidity have been found to be linked to the increased spread of a diarrheal illness a new study reveals. The findings could help predict further outbreaks of the illness, potentially leading to better preparedness within health services.

Scientists, farmers and managers work together to avoid the decline of the little bustard, an endangered steppe bird      (via sciencedaily.com)     Original source 

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.

Rain can spoil a wolf spider's day, too      (via sciencedaily.com)     Original source 

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.

Climate change isn't producing expected increase in atmospheric moisture over dry regions      (via sciencedaily.com)     Original source 

The warming climate has not lead to an expected increase in atmospheric moisture over arid and semi-arid regions of the world. The finding, which has surprised scientists, indicates that some regions may be even more vulnerable to future wildfires and extreme heat than projected.

Tiny AI-based bio-loggers revealing the interesting bits of a bird's day      (via sciencedaily.com)     Original source 

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.
