Combatting a deadly disease and conserving a landscape one frog at a time

New research supported by the U.S. National Science Foundation shows that efforts to save and reintroduce mountain yellow-legged frogs across Yosemite National Park are helping to sustain the population in the face of a deadly fungus and have the potential to inform other conservation efforts.

The amphibian chytrid fungus, Batrachochytrium dendrobatidis, which causes a disease known as chytridiomycosis, has devastated frog populations worldwide. In Yosemite, the Sierra Nevada yellow-legged frog lives in only 10% of its historic range due to population losses from the disease and other factors. Working to determine methods of saving the remaining frogs and combat the disease, researchers led by UC Santa Barbara (UCSB) biologist Roland Knapp previously demonstrated that frogs from populations that recovered naturally from B. dendrobatidis-caused declines appear to have evolved increased B. dendrobatidis resistance. In the current study, Knapp and his colleagues collected frogs from these resistant populations and reintroduced them into areas where the disease had previously wiped out frogs.

Over 17 years, Knapp, a member of the NSF Resilience Institute Bridging Biological Training and Research, an NSF Biology Integration Institute, and the team conducted 24 reintroductions across 12 sites in Yosemite. Monitoring the populations over that time, they found that the frogs could establish themselves in the previously devastated areas, even in the face of ongoing B. dendrobatidis infection, and that how well these

In-depth analysis

December 18, 2024

The U.S. Environmental Protection Agency’s (EPA) Gasoline Sulfur program sets limits on the sulfur content of gasoline sold in the United States, with the aim of reducing a variety of vehicle emissions. The program relies on tradable credits that allow U.S. refiners and gasoline importers to reach compliance with sulfur specifications. For the second year in a row, in 2023, gasoline suppliers obtained and retired more sulfur credits than they generated, a trend that could increase supplier compliance costs and the price of octane in gasoline if it continues.

Sulfur is a natural component in crude oil that is present in gasoline, diesel, and other petroleum fuels unless it is removed. The presence of sulfur makes vehicle emission control systems less effective and contributes to air pollution. Reducing the sulfur content in
