Mountain Lion Mortality Maps Show Rough Road for Cougars

As Los Angeles prepares to celebrate the life of beloved mountain lion P-22 this weekend,  mountain lion mortality maps from the University of California, Davis, show that many cougars suffer similar fates along California’s roads and highways.

Shedd Aquarium Lends Support to Conservation Effort for Magellanic Penguins in Patagonia

New collaboration looks to understand wild penguin diets to protect food sources and prepare for climate impacts

Members of Shedd Aquarium’s animal care team recently returned from South America, where they monitored a wild Magellanic penguin colony and collected guano samples for future analysis. The samples will help reveal the diets of these animals, which live in a variable and unpredictable zone in terms of food resources, to ensure their prey are identified and protected.

Scientists Rule Out Human Herpesvirus in Endangered Gorillas With Help From Chewed Plants

A mountain gorilla walks in the forest of East Africa’s Virunga Volcanoes conservation area. It stops at a piece of wild celery, sits down, and begins to chew. It strips the vegetable’s fibrous threads through its teeth, extracting the fleshy, juicy bits, then drops the chewed stalk on the ground and ambles away.

Citizen divers aid understanding of fish in the Salish Sea

Hundreds of fish species live in the Salish Sea, and many face a number of threats. Monitoring the health of these fish populations is crucial. But with nearly 5,000 miles of coastline and more than 400 islands, it’s no small task.

Historically, monitoring fish populations has included fishery catch data, active trawl surveys, underwater video, satellite imagery, hydroacoustics and more. But citizen scientists are increasingly playing crucial roles, according to a study from the University of California, Davis.

Mange Outbreak Decimated a Wild Vicuña Population in Argentina

Mange has decimated the population of wild vicuñas and guanacos in an Argentinian national park that was created to conserve them, according to a study from the Administration of National Parks in Argentina and the University of California, Davis.

The findings, published today in the journal PLOS ONE, suggest domestic llamas introduced to the site may have been the source of the outbreak. Cascading consequences for local predator and scavenger species are expected.

Latest Mountain Gorilla Census Results

Mountain Gorilla Numbers on the Rise

A 2018 survey shows that mountain gorilla numbers have increased in Bwindi Impenetrable National Park, Uganda and Sarambwe Reserve, DR Congo, according to the Uganda Wildlife Authority. The 2018 Bwindi-Sarambwe mountain gorilla survey found a minimum of 459 mountain gorillas in these regions, an increase from the previous survey estimate in 2011 of 400. When combined with the 2015-2016 population survey results of 604 mountain gorillas in the Virunga Massif, the total world population of endangered mountain gorillas now stands at 1,063.
