Rare Nevada fish 'staring down the barrel of extinction' could earn endangered species protections

An olive-colored minnow only found in southwestern Nevada is one step closer to life-saving federal protection after years of advocacy.
The Fish Lake Valley Tui Chub, which gets its name from its threatened habitat in Esmeralda County, Nevada, is an olive-brass fish only found in a single spring and a pond outside its native range, according to the Center for Biological Diversity.
The U.S. Fish and Wildlife Service (USFWS) says the fish species' historic range included other bodies of water near Dyer, Nevada, but other populations have all expired. Changes in the Earth's climate dried up the Fish Lake Valley Tui Chub's larger habitat more than 500,000 years ago, isolating them to a small spring on the valley floor.
Cut The Head Off This Invasive Python-looking Fish If You See It, Conservationists Say
On Wednesday, the U.S. Fish and Wildlife Service filed a petition to list the fish as endangered under the Endangered Species Act of 1973.
This milestone is years in the making. In March 2021, the Center for Biological Diversity petitioned the U.S. Fish and Wildlife Service to list the fish as an endangered species. A 2022 study by the USFWS found the petition warranted further action.
According to the USFWS petition, experts have determined that the small fish is threatened by agricultural production and land management practices, the effects of climate change on its habitat, and competition with invasive species.
Great Basin Director for the Center for Biological Diversity Patrick Donnelly said in a statement that the rare fish could become extinct because of groundwater pumping for agriculture, including alfalfa for livestock.
Arctic Sets Record For Smallest Winter Ice Coverage
"The Fish Lake Valley Tui Chub is staring down the barrel of extinction, and only the Endangered Species Act can save it now," Donnelly said. "We're going to keep fighting to save it and the remarkable biodiversity of Fish Lake Valley."
The Center for Biological Diversity said impending mining and energy projects in the area will only worsen matters. The center filed a lawsuit to stop the Rhyolite Ridge lithium mine from moving forward because of its threats to biodiversity.
"The Fish Lake Valley Tui Chub is barely clinging to existence. I'm thrilled these fish are poised to get the life-saving protections they urgently need," said Donnelly. "Nevada has already lost so many native fish species. We can't afford any more extinction."The petition from the USFWS opens a 60-day comment period before further action.Original article source: Rare Nevada fish 'staring down the barrel of extinction' could earn endangered species protections

Gray whale numbers decline to lowest since early 1970s, according to new data

The number of Pacific gray whales decreased significantly during the most recent count to the lowest numbers since the 1970s, while the number of whale calves also hit its lowest numbers on record. Gray whales, known for their migrations along the Oregon Coast in winter and spring, dropped to an estimated 12,900 adults and 85 calves in the latest data taken by the National Oceanic and Atmospheric Administration. It was a sharp decline from a year ago, when the number of gray whales was estimated at 19,260 for 2023-2024, and calf numbers were estimated at 221 in 2024 and 412 in 2023. "Our main concern and question is why the population does not appear to be demonstrating the same resilience as it has in rebounding from previous downturns," Sarah Mesnick, ecologist and science liaison with NOAA, said. The new data reversed hope from scientists that gray whales were rebounding after they endured an 'unusual mortality event' from 2019 to 2023 and worried instead that whales may be struggling to keep up with a changing environment. "The environment may now be changing at a pace or in ways that is testing the time-honored ability of the population to rapidly rebound while it adjusts to a new ecological regime,' said David Weller, director of the marine mammal turtle division at the NOAA Science Center and an authority on gray whales. Researchers in Mexico reported numerous dead gray whales early in 2025 in and around coastal lagoons as well as few gray whale calves. This suggests that many female whales may not be finding enough food in the Arctic to reproduce. So far in 2025, 47 gray whales have stranded dead on the West Coast, up from 31 in 2024 and 44 in 2023, the last year of the UME. While some of the stranded whales appeared skinny or emaciated, others did not. 'The lead scientists point out that this new estimate stands out because it reflects an extended downward trend in a population that has demonstrated short-term resilience in the past,' Mesnick said. 'The populations have previously rebounded quickly from downturns, including earlier previous UMEs, and we are going to continue to monitor the population.' According to NOAA and under the Marine Mammal Protection Act, UME "involves a significant die-off of any marine mammal population; and demands immediate response." Causes of UME are attributed to infectious disease, biotoxins, ecological factors, human interactions and other undetermined factors. The gray whale population was large, at about 27,430 between 2015-2016. In the following years, a decline started from 2019-2023 to below 15,000 that was considered as unusual mortality event. It appeared that whales might by rebounding after 2023, but the latest numbers dispute that notion. Scientists attributed the die-off to localized ecosystem changes that affected the Subarctic and Arctic feeding grounds. The changes in these areas contributed to malnutrition, reduced birth rates and increased mortality. The migration routes, specifically the California Current ecosystem and the Arctic ecosystem, have experienced significant changes in recent decades as well, officials said. The current research shows a connection between gray whale numbers and changes in sea ice in the Arctic, where most gray whales feed during the summer, NOAA concluded. 'They're migrating from Mexican reproductive ground, or nursery grounds, to foraging grounds in the Arctic,' Mesnick said. 'It's one of the longest migrations on the planet.' Ecosystem changes in the Arctic feeding areas the whales depend on to put on weight and maintain fitness are likely the root cause, Weller said. Decline in calf numbers has been linked to sea ice cover in the Bering and Chukchi seas. In May 2024, a juvenile gray whale washed ashore on a beach in Bandon along the southern Oregon Coast. In 2023, four reported gray whales washed ashore Oregon beaches, one being a calf. Mariah Johnston is an outdoors journalism intern at the Statesman Journal.

Satellite streaks block out the Arctic sky

When you buy through links on our articles, Future and its syndication partners may earn a commission. From intelligence gathering to internet usage to navigation, satellites are used daily across the globe. However, their activity is causing serious issues. In February, a team of researchers from Western University in Canada, in collaboration with the organization Defense Research and Development Canada, trekked into the high Arctic to try to measure the activity of satellites orbiting across the pole. Using 14 low-cost cameras, the researchers were able to track satellites passing overhead on the evening of Feb. 22, 2025, compiling them into a long-exposure image to show the total activity for the evening. Each streak of white in the image shows the satellite's path in the sky. Their system was inspired by meteor tracking, with cameras pointed in various angles to catch the entire night sky. This photo was taken in Eureka, in the Canadian territory of Nunavut. This novel satellite system has allowed the researchers to produce the first ever full year of satellite tracking data over Canada, according to Western University. The system is currently deployed at four sites across Canada to monitor satellite activity including: Eureka, Osoyoos, British Columbia, and Lucky Lake, Saskatchewan. With the 14-camera setup, the researchers could track objects in the sky over 11.8 inches (30 cm) in size. To date, the system has found over 17,000 unique satellites and clocked nearly half a billion observations, according to the press release. While the system gives a more detailed way to monitor satellite activity, it also reveals just how full our skies are with these devices. Not only are satellites chemically polluting our atmosphere with heavy metals, but they are becoming a growing issue for astronomers trying to look deep into our universe. With more launches planned to add new satellites, the question to be asked is: when will the sky be too full?

Researchers call for urgent exploration of methods to cool Earth

It is already obvious that some governments are not acting fast enough to keep the planet's temperature from rising dangerously. While it is essential to continue to concentrate on reducing methane and carbon dioxide emissions as quickly as possible, other methods of cooling the planet need to be urgently explored, according to academics at the University of Cambridge's engineering department. Related: UK scientists to launch outdoor geoengineering experiments One of the problems is that many of the ideas put forward so far, including injecting sulphates into the atmosphere to reflect sunlight back into space, could do more harm than good. This is because sulphates cause acid rain and interfere with rainfall patterns. To avoid controversy researchers are experimenting with alternatives to sulphates, substances that reflect sunlight but are benign. They will hoist them into the stratosphere using weather balloons then recover them to see what changes this exposure causes. No materials will be released but their cooling effect and whether they could otherwise be harmless can be gauged. Other ideas like drilling holes in the Arctic ice in the winter and pumping seawater over existing ice floes in below freezing air temperatures to thicken them are also being tried, along with spraying seawater to form clouds over the ocean, also to reflect sunlight. If these ideas are otherwise harmless, and work, they might yet save us.
