South Park Drive in Tilden to close for 5 months to protect newts

Berkeleyside reported

The closure, which has been done during the newts’ seasonal migration since the 1980s, allows the salamanders to seek out the higher air moisture levels they favor for breeding.

From Nov. 1 through March 31, South Park Drive will be closed to all automotive traffic, and cyclists are asked to proceed slowly and keep an eye out for the little beady-eyed creatures, which usually run 5 to 6 inches long. Dogs should be kept away from the amphibians as California newts are poisonous to pets. Drivers can use the alternative routes of Grizzly Peak Boulevard, Wildcat Canyon Road and Central Park Drive during the five-month closure.

The secret to growing food on Mars could be fungi

ScienceDaily reported

Scientists think beneficial fungi could help transform nutrient-poor lunar and Martian regolith into a material capable of supporting crops. By helping plants access nutrients and withstand harsh conditions, these microbes could someday make self-sustaining space farming more realistic.

Three-Legged Persian Leopard’s 150-Mile Trek Highlights Survival in Minefield-Scarred Caucasus – EnviroLink Network

EnviroLink reported

Sightings of the endangered Persian leopard in the Caucasus have been rare over the past 20 years — just three in Georgia and 10 in Armenia. But one leopard in particular has caught the attention of scientists and conservationists. Named Aren, the leopard is presumed to have traveled 240 kilometers (150 miles) through cold, mountainous terrain on only three legs. The region, which spans southern Russia, Georgia, Armenia and Azerbaijan, still contains decades-old minefields left from past conflicts, and it’s believed this is how Aren lost the use of one leg.

Aspen trees remember drought and strengthen their defenses a year later

Earth.com reported

Aspen trees respond to past droughts by increasing their chemical defenses against insects, revealing a surprising form of environmental memory.

The leaves a quaking aspen grows the year after a drought carry about a tenth more of the compounds that keep insects from eating them. Those leaves never saw a dry day.

Near Arches National Park, a new dinosaur species emerges from the ground

SF Gate reported

Fossils representing at least 4 dinosaur groups were discovered at the Ironstone Bonebed

Earlier this month, paleontologists with the Utah Geological Survey broke ground on a new excavation site in the Utah desert just outside Arches National Park. The land, newly dubbed the Ironstone Bonebed in homage to the rust-red hue of its rocks, sits in an area rife with dinosaur history, and already, it has offered up its first exciting find: a seemingly new species of armored dinosaur.

Yosemite National Park’s bears are having a terrible year

SF Gate reported

If you visited Yosemite National Park this month, and stayed for at least three days, it is likely that a bear got hit by a motorist during your visit. Since Oct. 1, seven black bears have been struck by vehicles in the park, and four of those collisions were fatal for the animals, National Park Service spokesperson Rebecca Roland told SFGATE by email on Thursday.

Those strikes were on top of 26 that took place from January through September. At 33 bear collisions for 2026 so far, Yosemite has reached a 10-year high, according to National Park Service data, with more than two months left in the year. Conservationists say they are troubled, but not shocked, by the uptick.
