Shade Trees Reduce Street Temperatures 2.6 Degrees Celsius

Space Daily reported

Research cited by Singapore’s urban planners suggests shading roads with trees can reduce street-level temperatures by up to 2.6 degrees Celsius — separately, models suggest tree shade on buildings can meaningfully lower air-conditioning demand nearby

Peru’s only penguin species at risk from upcoming El Niño and bird flu

Monga Bay reported

  • The Humboldt penguin is the only penguin species to breed in Peru, inhabiting the country’s coastal deserts. But since 2022, the species’ has been under pressure from the spread of avian influenza, followed by El Niño.
  • Between 2022 and 2025, the population of Humboldt penguins has dropped by two-thirds across 34 islands and peninsulas on the Peruvian coast.
  • Experts monitoring the species say penguins are abandoning their nests as they already feel the impacts of the upcoming El Niño episode, which changes temperatures in coastal waters and diminishes the amount of prey fish available.
  • Scientists are asking both the national government and the IUCN to revise the species’ status to reflect the increasing threats and boost conservation efforts.

Blue Whales Shouldn’t Be Able to Hunt The Way They Do. Scientists Have Finally Discovered How They Pull It Off

ScienceAlert reported

When a blue whale dives below the waves, their heart rate plummets to conserve oxygen.

Their massive hearts can slow to just two beats per minute as they dive hundreds of meters in search of food.

Tracking Elephants

ScienceBlog reported

In 2023, conservationists fitted a young bull elephant in Zambia with a GPS collar. Two years and nearly 12,000 kilometers later, his tracks had crossed four countries and six national parks — tracing migration routes elephants have followed for generations, now cut through by human borders they never agreed to.

Ancient elephant highways are colliding with modern borders, revealing how conservation zones fail the animals they’re meant to protect.

Timber Fire Now Third Largest in State, CHP Announces Highway 1 Closure

KQED reported

A stretch of Highway 1 in Big Sur will close again Thursday in an effort to regain control over the Timber Fire.

The fire has burned nearly 19,000 acres as of Wednesday — more than double what prompted initial evacuations on Aug. 10.

The Timber Fire is now the third biggest fire in the state this year, according to CalFire. Much of that spread has been to the east, moving deeper into the Los Padres National Forest.

Biologist Fernanda Abra strung rope bridges above an Amazon highway and 15,000 animals crossed safely without a single death

Eco Portal reported

In 2024, Projeto Reconecta installed eight rope canopy bridges near Alta Floresta, connecting fragmented forest patches over a local highway. The results, documented over 15 months of camera-trap monitoring, were unambiguous: 15,000 safe crossings by arboreal animals, and not a single roadkill event recorded.

How Forest Fires Affect Insects

Xerces Society reported

Fire has always been part of the ecosystems of the western United States, but the fires we are experiencing now are bigger and hotter than they used to be. This is partly because of years of fire suppression, but is also a result of the changing climate. Invertebrates from caddisflies to slugs to bees and butterflies are likely negatively affected, but we still have much to learn about the effects on these populations.

8 most poisonous birds on the planet

Discover Wildlife reported

If you’re thinking of some enormous flying creature with teeth or talonscarrying deadly venom, you’ll need to reign in your imagination. No known bird actively injects or produces venom – but the poisonous birds on this list do contain deadly toxins within their skin, feathers and other tissues.

Where do they get these toxins from? They don’t produce them themselves but rather engage in a process called heteroaglandular poison – poison produced as a result of consuming a certain toxin which is then re-used for the animal’s own defences.

As the American West dries out, a secret savior emerges from the soil

SF Gate reported

Living crusts produce and reinforce desert soils, laying a foundation upon which all else grows.

Scientists are now learning that biocrust plays important roles in everything from erosion control and nutrient cycling to bracing against the worst impacts of climate change. And as temperatures continue to rise, researchers are turning to these living soils as a potential tool for restoring healthy landscapes.

Nature’s air conditioner: How urban forests are cooling Korea’s heat waves

Korean Times reported

As record heat waves continue to bake concrete jungles across the globe, city planners looking for thermal relief may find their best tool planted right outside their front doors. According to new research from Korea’s National Institute of Forest Science, urban forests serve as powerful, natural air conditioners, slashing daytime temperatures by nearly 2 degrees Celsius compared to heavily built-up city centers.

Bumblebees collect up to 7 times more toxic metals than honeybees

ScienceDaily reported

Bumblebees are picking up dramatically more toxic heavy metals than honeybees, even when both species forage in the same places. Researchers warn that this hidden pollution could quietly reduce their ability to find food, reproduce, and keep colonies healthy.

Blood Is Life — The Amazing Dragon’s Blood Tree

The Revelator reported

New research proposes classifying the threatened tree as an “umbrella species” because of its oversized ecological role.

Dragon’s blood trees (Dracaena cinnabari) are evolutionary marvels of the plant kingdom, but they may not be around forever.

Native to a single island in the Socotra archipelago, off the coast of Yemen in the Arabian Sea, the extraordinary-looking dragon’s blood tree, which is classified as “vulnerable to extinction,” can grow to more than 30 feet in height and live for 600 years. Looming over the island’s rocky, mountainous terrain, it produces rich berries and a vermilion sap — the source of its name — that has been used for centuries as everything from medicine to lipstick, and even as a varnish for violins.

Judge Vacates Land Exchange, Halts Road Through Izembek National Wildlife Refuge

Defeneders of Wildlife reported

A federal judge today vacated an illegal closed-door deal between the U.S. Department of the Interior and a for-profit Alaska Native corporation, King Cove Corp., that exchanged a 10.5-mile corridor of Izembek National Wildlife Refuge and Wilderness lands to enable a 18.9-mile gravel road connecting King Cove and Cold Bay. U.S. District Court of Alaska Judge Sharon Gleason found that the federal government violated the National Wildlife Refuge System Administration Act, the Endangered Species Act and the Alaska National Interest Lands Conservation Act.
