Yellowstone National Park wolf pups face ‘particularly lethal’ virus
SF Gate reported
Yellowstone National Park’s famous wolf packs are facing an invisible threat that’s bringing the number of surviving pups to historic lows: a contagious viral disease called canine distemper.
At the end of 2025, Yellowstone National Park had 84 wolves dispersed among seven packs, according to spokesperson Linda Veress. This amounts to an approximately 16% decrease from the average end-of-year population over the past 15 years. Veress told SFGATE that the number of Yellowstone wolves fluctuates and that the park still supports a “healthy population,” but also acknowledged that the virus is likely taking a toll.

Oak trees are delaying spring to starve caterpillars
ScienceDaily reported
Oak trees have a surprising trick to fight back against hungry caterpillars: they simply wait. When trees are heavily attacked one year, they delay leaf growth by just three days the next spring—long enough to leave newly hatched caterpillars with nothing to eat. This small shift slashes insect survival and reduces leaf damage by more than half, proving even more efficient than costly chemical defenses.

Locals are pushing back on a logging proposal on the edge of Yellowstone National Park
SF Gate reported
Last summer, residents of Gardiner and Jardine, Montana, heard through the grapevine that a large-scale logging project might be coming to their doorstep on the northern edge of Yellowstone National Park. What’s since been proposed, though, is larger than they ever could have imagined.
It would entail 4,401 acres of logging and thinning, including 2,126 acres of commercial logging — with 824 acres of that clear-cut — as well as prescribed fire operations in the Custer Gallatin National Forest. The project would span four creek drainages and authorize the construction of 7 miles of new roads.

Poop From Young Mice Reverses Signs of Age-Related Decline in Older Mice
Science Alert reported
Supplementing the guts of older mice with poop from younger ones reveals the key role microbes play in intestinal stem cell function, recent research shows.
After receiving a fecal microbiota transplant from younger mice, one aspect of age-related decline in the guts of older mice was reversed, driven by increased intestinal stem cell activity that maintains the intestinal walls.

Asian Forests Grow Increasingly Silent as Gibbon Trafficking Hits an All-Time High
The Revelator reports
Traumatized, orphaned gibbon babies are stuffed into luggage and smuggled by air from southeast Asia to India.
For well over a year now, the Save the Gibbons Alliance, a group of small-ape conservationists and media professionals focused on protecting these long-armed primates from illegal trade, has been tracking a worrying problem. They’ve documented at least one gibbon-smuggling incident per month, either at a southeast Asian airport or an Indian one, each involving multiple gibbon babies or juveniles. News reports of these seizures in the local media are often accompanied by heartbreaking images of distressed or dead gibbon babies, stuffed into check-in or carry-on baggage.

Hundreds of Khulan return to Eastern Mongolia after 65-year absence
Monga Bay reported
The Asiatic wild ass, or khulan, is reestablishing itself in eastern Mongolia for the first time in more than six decades, according to a recent study. It found hundreds of these wide-roaming herbivores have successfully crossed through a gap along the perimeter of the otherwise fenced-off Trans-Mongolian Railway, a barrier that kept them restricted to the west of the tracks since the mid-20th-century.

San Francisco turns to AI to save whales from ship strikes as deaths soar
The Guardian reported
Climate change is pushing starving grey whales to San Francisco Bay, where ship strikes led to 40% of 21 deaths.
Until now, whales could easily go unnoticed by mariners, but an AI-powered detection network launched this week is designed to track them day and night.
The system, called WhaleSpotter, scans the bay around the clock for whale blows and heat signatures up to 2 nautical miles away, alerting mariners to slow down or reroute when whales are nearby.

Tougher than they look: Wildflowers mix it up to survive drought
The Enterprise reported
Lupine and California golden poppies are already blooming everywhere. They’re more than beautiful, and tougher than they look: Wildflowers can teach us a lot about surviving drought.
A new study shows wildflowers employ a mixture of strategies, some intentionally risky and others cautiously conservative, both above-ground and below, to thrive in conditions that can vary widely from year to year. With climate change making drought more frequent and more severe, this work hones the ability of land managers to predict which plants will thrive in which ecosystems in the future.

As U.S. national parks hike fees for international visitors, Canada is letting them in free
SF Gate reported
While the U.S. hits international visitors with additional fees to enter national parks this year, our neighbors to the north are trying a different approach: Canada’s national parks will be free to enter during the peak summer travel season.
The Canada Strong Pass, available to Canadians and international visitors, allows anyone to visit any of the country’s 48 national parks free of charge between June 19 and Sept. 7. The program also provides a 25% discount on camping fees, discounts for young adults at national museums and reduced fares on the cross-country VIA Rail.

New Scientific Study Assesses State of Giant Sequoias, Reveals 18% Mortality of Mature Trees Due to Severe Wildfires
Giant Sequoia Lands Coalition reports
Only 26% of giant sequoia range shows high resistance to extreme wildfires; Roughly 13% of the range at risk of local extinction.A new scientific study from the Giant Sequoia Lands Coalition (GSLC) reveals the current state of California’s giant sequoia range and quantifies the alarming extent of damage caused by extreme wildfires over the last decade. More than 17% of all mature giant sequoias have been killed by wildfire since 2015, while less than 1% perished in the 30 prior years. Most of the losses since 2015 occurred during the megafires of 2020 and 2021.

A massive new transmission line is being planned through the heart of Anza-Borrego Desert State Park — and right now, the public has a meaningful opportunity to help inform the process. The Golden Pacific Powerlink is a proposed 500-kilovolt (kV) high-voltage transmission line that would run approximately 135 miles from the Imperial Valley Substation in southern Imperial County to the border of San Diego and Orange Counties, near the decommissioned San Onofre Nuclear Generating Station.

Preserving pollinators is good for health — and income
NPR reported
Nature clearly benefits human health. Research shows how trees clear the air, wetlands filter water and insects pollinate food.
But moving beyond these generalities to specifics is hard, says Thomas Timberlake, an ecologist at the University of York. Figuring out which parts of an ecosystem are most important, and how much they bolster the health of people and communities is difficult to quantify.
