Two members of California’s small but rebounding gray wolf population have been located and given tracking collars, bolstering the state’s conservation efforts, the California Department of Fish and Wildlife announced Friday.

The agency says they located and captured the two wolves on March 17 in Siskiyou County through “intermittent signals” coming off the malfunctioning collar of one wolf. The wolves were given satellite collars, which will transmit regular location updates back to the department.

They were then released back into the wild.

“The capture of these wolves is fantastic since we lost the only functioning satellite collar last summer, and ground capture efforts since then have been unsuccessful,” Kent Laudon, wolf specialist and senior environmental scientist for the department, said in a statement. “A lot of people have worked hard to make this happen, and we’re excited about the new collars and data.”

Collaring the wolves and tracking their movements is a critical part of rehabilitating the diminished population, which were hunted to the point of extinction in the state in the 1920s. Since 2014, gray wolves have been protected under the California Endangered Species Act, and hunting them is prohibited. The loss of the apex predator has had dramatic impacts throughout the food chain and has thrown the delicate balance between predators and prey into disarray.

Wolves have slowly returned to California, trotting in from other states. One such wolf, known as OR-93, famously made the journey from western Oregon, crossing freeways and mountain passes until he arrived in Southern California. The odyssey ended tragically, with the wolf fatally struck by a car near Interstate 5 in late 2021. Nevertheless, his epic journey was hailed by wolf advocates, who said it gave them hope the species might one day safely roam wild across the region once again.

One of the wolves captured last week, called OR85, was also from Oregon and had been captured and collared by the Oregon Department of Fish and Wildlife in February 2020. Later that year, he made the journey from northeastern Oregon to the northernmost part of California.

Now 4 years old and 98 pounds, OR85 was found alongside a 1-year-old, 97-pound male wolf believed to be from a litter he had in 2021. OR85 mated with a gray female wolf from southwestern Oregon, who gave birth to seven pups in 2021 and eight pups last year.

The rebounding gray wolf numbers have created tension across the West between conservationists, who want to see the population return, and ranchers and farmers, who say their livestock are routinely threatened. The state says it shares information gleaned from the collars with cattle and sheep ranchers to alert them to nearby wolf activity.

Mexico sanctioned for not protecting endangered porpoise

Mexico announced in the first week of March 2023, that it is seeking to avoid potential trade sanctions for failing to stop the near-extinction of the vaquita, the world’s smallest porpoise and most endangered marine mammal. Studies estimate there may be as few as eight vaquitas remaining in the Gulf of California, the only place they exist and where they often become entangled in illegal gill nets and drown.

Continental shelves form the edge of the continent. They extend up to 300 miles out to sea and, compared to the majority of the ocean floor, have shallow water. Their shallow depths and relative proximity to land allow continental shelf waters to be productive.

For example, the bottom of continental shelves serves as critical habitats for commercial species such as lobsters, scallops, crabs, flounder, cod and other groundfish, according to the National Oceanic and Atmospheric Association (NOAA).

These habitats, however, can become compromised when waters close to the seafloor experience heat waves, according to a paper published by researchers from NOAA, the National Center for Atmospheric Research (NCAR) and the Cooperative Institute for Research in Environmental Sciences (CIRES).

Called bottom marine heat waves, these temperature anomalies can occur with little or no evidence of warming at the surface.

This can have important implications for commercial fisheries, which may not realize the occurrence of the heat wave until the impacts start to show, said lead author Dillon Amaya, a research scientist with NOAA’s Physical Science Laboratory.

HOW TO WATCH FOX WEATHER

One such impact was found in 2021 after a multi-year marine heat wave known as “The Blob” swept through the northern Pacific Ocean. 

According to NOAA, the Blob included masses of water between 4 and 10 degrees Fahrenheit above average that disrupted West Coast marine ecosystems, depressed salmon returns, and caused millions of dollars in damages to commercial fisheries.

Bottom marine heat waves have also been linked to the expansion of invasive lionfish, a tropical fish species that prey on native species along the southeast U.S. coastlines.

NOAA said other impacts caused by unusually warm bottom water temperatures include the disappearance of near-shore lobster populations in southern New England, coral bleaching and declines of reef fish and changes in survival rates of young Atlantic cod.

Marine heat waves have become increasingly common. According to NOAA, they have become about 50% more frequent over the past ten years.

Three men caught hare-coursing in Warwickshire are first people to convicted under new rural laws

23rd March 2023

Three men caught hare-coursing in Warwickshire are the first people to convicted under new laws to tackle the crime.

They were all ordered to pay more than £2,000 and banned from owning dogs for five years after pleading guilty at Warwickshire Magistrates Court on Friday March 17 to hare-coursing offences in the Brinklow area.

A spokesperson for the Warwickshire Rural Crime Team said: “The males are the first to be charged in Warwickshire under new laws to tackle illegal hare-coursing.

“The Police Crime Sentencing and Courts Act 2022 makes it an offence to go equipped for, search for, or pursue hares with dogs, and an offence to trespass with intent to search for or pursue hares with dogs.

“Equipment used in the commission of the offence was also forfeited.

An outbreak of H5N1 avian influenza that started in 2021 has become the largest bird flu outbreak in history, both in the US and worldwide. In the US the virus has led to the destruction of millions of commercially raised chickens, turkeys, ducks and geese, and has killed thousands of wild birds.
 
Many virologists are concerned that this virus could spill over to humans and cause a new human pandemic.
 
University of Colorado Boulder virologists Professor Sara Sawyer, Emma Worden-Sapper and Sharon Wu summarise the compelling story of H5N1 and why scientists are closely watching the outbreak.

The future of humanity’s “lifeblood” — water — is under threat worldwide, the UN secretary-general warned Wednesday at the opening of the global body’s first major meeting on water resources in nearly half a century.

“We’ve broken the water cycle, destroyed ecosystems and contaminated groundwater,” Antonio Guterres said at the three-day summit in New York, which gathers some 6,500 participants including a dozen heads of state and government.

“We are draining humanity’s lifeblood through vampiric overconsumption and unsustainable use, and evaporating it through global heating,” Guterres told the conference.

A report by UN-Water and UNESCO released Tuesday warned of too little or too much water in some places, and contaminated water in others — conditions it said highlight the imminent risk of a global water crisis.

“If nothing is done… it will keep on being between…

CARSON COUNTY, Texas (KXAN) — Askunk recovered from Carson Countyis Texas’ first confirmed case of avian influenza in a mammal.

The National Veterinary Services Laboratories (NVSL) confirmed this week the presence of Highly Pathogenic Avian Influenza (HPAI) in a striped skunk recovered from the north Texas county.

According to the Texas Parks and Wildlife Department, HPAI is a highly contagious virus that transmits easily among wild and domestic birds and is detected in all U.S. states except Hawaii. The virus can spread directly between animals and indirectly through environmental contamination.

For mammals, current data shows transmission occurs primarily through the consumption of infected animal carcasses, though mammal-to-mammal transmission does not appear sustainable, TPWD said in a news release.

TPWD said other mammal species susceptible to HPAI include foxes…
