Logging, linear features, and human infrastructure shape the spatial dynamics of wolf predation on an ungulate neonate

Posted on November 29, 2023

Humans are increasingly recognized as important players in predator–prey dynamics by modifying landscapes. This trend has been well-documented for large mammal communities in North American boreal forests: logging creates early seral forests that benefit ungulates such as white-tailed deer (Odocoileus … read more

The ethology of wolves foraging on freshwater fish in a boreal ecosystem

Posted on June 3, 2023

Through global positioning system (GPS) collar locations, remote cameras, field observations and the first wild wolf to be GPScollared with a camera collar, we describe when, where and how wolves fish in a freshwater ecosystem. From 2017 to 2021, we … read more

Good news for Lobos previously removed to captivity. They have returned to the wild!Some good news out of Arizona! On Monday, the U.S. Fish and Wildlife Service translocated a Mexican gray wolf family back to the wild in southeastern Arizona, a move we are celebrating as a successful step in lobo recovery. The wolves, a female called “Llave” (#1828) and her mate, “Wonder” (#2774) were both originally born in the wild in the Mexican Wolf Experimental Population Area.Both wolves were removed from the wild last fall with the intention that they would pair bond in captivity prior to translocation back in the home range on the border of New Mexico that Llave shared with her previous mate (#1582), who was killed in spring 2023. During the summer of 2023, she made several forays north of Interstate 10 but never found a male on her own, leading to her capture in the Peloncillo Mountains. Wonder was removed in November from the San Carlos Apache Reservation at the Tribe’s request. Both wolves spent the winter in captivity at Sevilleta National Wildlife Refuge near Albuquerque.westernwatersheds.org/2024/04/greens-applaud-translocation-of-mexican-gray-wolves-to-southeastern... ...

Remote Lake Superior Island Wolf Numbers Are Stable but Moose Population Declining, Researchers Saytinyurl.com/3n5kz55xA team led by Michigan Tech University researchers was two weeks into this year's seven-week survey in January when unusually warm temperatures left the ice around the island unsafe for their planes to land. They were forced to evacuate the island and could not return.Data the team gathered before they left shows the wolf population stands at 30 animals, down from 31 animals last year but up from 28 in the winter of 2022. The scientists said they believe the wolves have divided themselves into four packs, with one pack numbering at least 13 wolves. At least one wolf appeared to be living alone.The moose population, meanwhile, stood at 840, down 14% from last year. Overall, the moose population has declined by almost 60% since 2019, when the population peaked at a little more than 2,000 animals. (Wolfwatcher note: the goal of reintroducing wolves was to reduce the moose population, because they were starving)In past years, most moose died from starvation, the scientists said. Moose can eat up to 40 pounds of vegetation daily and with low wolf numbers, the population grew unchecked and the creatures ate themselves out of food. But this year's decline is likely linked to wolf predation, they said. ... See MoreSee Less
