Grizzlies return to the North Cascades?

Source: Outdoor Life

Federal agencies aim to establish a population of up to 25 grizzlies in the Northern Cascades over the next 5–10 years. The plan categorizes these grizzlies as a ‘nonessential experimental population,’ a status that mitigates human-grizzly conflicts by relaxing protections granted by the Endangered Species Act.

Similar to livestock guardian dogs, a recent experiment shows an 88% reduction in bear visits to farms with dogs. While the study offers promise for cost-efficient coexistence, whether dogs can provide long term grizzly deterrence remains to be seen.

Economic wealth shapes mammal communities across 23 American cities.

Source: The Hill

Greater mammal diversity, including species like red fox, can thrive in higher income areas with dedicated parks and greenspaces, reports a new study. In contrast, lower-income areas often only support animals highly adapted to urban living, like rats. This research supports previous work that links urban biodiversity to health and wealth.

Firefighting beavers?

Known mostly for their disrupting dam-building, evidence suggests that beavers also provide numerous benefits, including fire protection, carbon storage, and water filtration. Some restoration efforts are embracing nature-inspired methods like building logjams to attract this keystone species back to its natural habitat.

Wolves are experiencing increased poaching and unexplained deaths.

Source: Oregon Capital Chronicle

While livestock predation explains the legal removal of 16 wolves—a high since recordkeeping began in 2008—illegal killings resulted in 12 additional deaths. At 178 wolves, the state’s wolf population did not increase for the first time in eight years.

Auctions of permits for limited-entry, once-in-a-lifetime hunts by conservation groups contributed to a total commitment of $4.8 million for habitat enhancement, wildlife transplants, and research. Of the 105 projects presented, 88 were partially or fully funded, positively impacting over 100,000 acres.

After two summers of surveying with remote cameras and hair snares, Oklahoma State University graduate student Bailey Kleeberg estimates a population of 26 black bears in the region. Genetic analysis suggests that these bears are coming from an established population in neighboring New Mexico.

How do scientists combat interbreeding among wild dogs in South Africa?

Source: The Conversation

With a population of about 550 individuals in 14 fragmented populations, low genetic diversity undermines the species’ resilience to rabies and canine distemper virus outbreaks. In response, researchers directly introduce valuable genes across populations via artificial insemination and seek to build an African wild dog sperm bank.

Mining threatens great apes

Source: Science Daily

Nearly one-third of gorillas, bonobos, and chimpanzees are at risk from mineral mining, highlighting the potential conflict between the transition to clean energy and conservation. While the extraction of copper, lithium, nickel, cobalt, and other rare earth elements in Africa is key to renewable technologies, researchers warn of a 20% overlap between mining areas and critical habitat for approximately 180,000 great apes.

A big win for conservation at Manovo-Gounda St. Floris National Park, Central Africa’s largest savanna park (17,400 square kilometers). UNESCO’s Man and the Biosphere Program recognizes the park’s new management plan, which called for hiring rangers to deter poaching and engaging local guards to liaise with livestock herders.

Rewilding Portugal introduces a version of the extinct aurochs cattle whose ancestors, depicted by paleolithic peoples in the region, played a key role in maintaining grassland ecosystems millennia ago. Now, their descendants will help establish a 1,200 sq km (463 sq miles) wildlife corridor along the Côa River.

Tapirs are acting as a sentinel species in Brazil, where pesticide contamination in captured animals led to a public health investigation. According to tapir specialist Patrícia Medici, researchers discovered the contamination when they encountered difficulties anesthetizing tapirs that hinted at possible organ damage.

Continuing in a time-honored naturalist tradition of observing wildlife during eclipses, citizen scientists digitally record behavior during the April 2024 eclipse. Previous observations indicate that some species treat the eclipse as if it were night, while others, such as lions, seem indifferent.
