Deer protected from deadly disease by newly discovered genetic differences      (via sciencedaily.com) 

It was the height of summer 2022 when the calls started coming in. Scores of dead deer suddenly littered rural properties and park preserves, alarming the public and inconveniencing landowners. According to officials at the Urbana Park District, it was Epizootic Hemorrhagic Disease (EHD), a midge-borne viral illness that pops up in white-tailed deer populations around the state every few years. And when susceptible deer are infected, they die within days. Now, scientists have found gene variants in deer associated with the animals' susceptibility to EHD.

Climate change, urbanization drive major declines in Los Angeles' birds in California, US      (via sciencedaily.com) 

Biologists use current and historical bird surveys to reveal how land use change has amplified -- and in some cases mitigated -- the impacts of climate change on bird populations in Los Angeles and the Central Valley over the past century. The study found that urbanization and much hotter and drier conditions in L.A. have driven declines in more than one-third of bird species in the region.

A fifth of California's Sierra Nevada conifer forests are stranded in habitats that have grown too warm for them      (via sciencedaily.com) 

Researchers created maps showing where warmer weather has left trees in conditions that don't suit them, making them more prone to being replaced by other species. The findings could help inform long-term wildfire and ecosystem management in these 'zombie forests.'

New research reveals 12 ways aquaculture can benefit the environment      (via sciencedaily.com) 

Aquaculture, or the farming of aquatic plants and animals, contributes to biodiversity and habitat loss in freshwater and marine ecosystems globally, but when used wisely, it can also be part of the solution, new research shows.

Researchers uncover how photosynthetic organisms regulate and synthesize ATP      (via sciencedaily.com) 

The redox regulation mechanism responsible for efficient production of ATP under varying light conditions in photosynthetic organisms has now been unveiled. Researchers investigated the enzyme responsible for this mechanism and uncovered how the amino acid sequences present in the enzyme regulate ATP production. Their findings provide valuable insights into the process of photosynthesis and the ability to adapt to changing metabolic conditions.

Noble false widow spider found preying on pygmy shrew      (via sciencedaily.com) 

Scientists have published the first record of a noble false widow spider feeding on a pygmy shrew, a species of tiny mammal protected in Ireland. The pygmy shrew -- a protected mammal -- was captured on spider's web on a bedroom window, then paralyzed and hoisted to its doom by the invasive spider.

Food quality matters for southern resident killer whales      (via sciencedaily.com) 

Not all Chinook salmon are created equal, and this has a major impact on the energetics for southern resident killer whales. A recent study quantified the lipid content in Fraser River Chinook salmon -- the southern resident's preferred meal -- and found that spring-run Chinook salmon, the earliest to arrive to the Salish Sea are lipid-rich and energy dense; a critical factor for the killer whales who prey on them. Fraser River Chinook salmon that come later in the season have lower energy density.

Feathered 'fingerprints' reveal potential motivation for migratory patterns of endangered seabirds      (via sciencedaily.com) 

New research shows that the feathers of seabirds such as the Wandering Albatross can provide clues about their long-distance foraging, which could help protect these species from further decline.

Using spiders as environmentally-friendly pest control      (via sciencedaily.com)     Original source 

Groups of spiders could be used as an environmentally-friendly way to protect crops against agricultural pests. That's according to new research which suggests that web-building groups of spiders can eat a devastating pest moth of commercially important crops like tomato and potato worldwide.

New technique maps large-scale impacts of fire-induced permafrost thaw in Alaska      (via sciencedaily.com) 

Researchers have developed a machine learning-based ensemble approach to quantify fire-induced thaw settlement across the entire Tanana Flats in Alaska, which encompasses more than 3 million acres. They linked airborne repeat lidar data to time-series Landsat products (satellite images) to delineate thaw settlement patterns across six large fires that have occurred since 2000. The six fires resulted in a loss of nearly 99,000 acres of evergreen forest from 2000 to 2014 among nearly 155,000 acres of fire-influenced forests with varying degrees of burn severity. This novel approach helped to explain about 65 percent of the variance in lidar-detected elevation change.

Western wildfires destroying more homes per square mile burned      (via sciencedaily.com) 

Between 2010 and 2020, human ignitions started 76% of the Western wildfires that destroyed structures, and those fires tended to be in flammable areas where buildings are increasingly common. Three times as many homes and other structures burned in these ten years than in the previous decade.

Understanding plants can boost wildland-fire modeling in uncertain future      (via sciencedaily.com) 

A new conceptual framework for incorporating the way plants use carbon and water, or plant dynamics, into fine-scale computer models of wildland fire provides a critical first step toward improved global fire forecasting.

How to apply lessons from Colorado's costliest wildfire to drinking water systems      (via sciencedaily.com) 

While communities and governments nationwide have been facing the impact of wildfires on drinking water systems, no national synthesis of scientific and policy needs has been conducted. Now, a study has outlined the scientific and policy needs specific to drinking water systems' resilience to wildfires.

What's driving re-burns across California and the West?      (via sciencedaily.com) 

Seasonal temperature, moisture loss from plants and wind speed are what primarily drive fires that sweep across the same landscape multiple times, a new study reveals. These findings and others could help land managers plan more effective treatments in areas susceptible to fire, particularly in the fire-ravaged wildland-urban interfaces of California.
