Soil life survived the Mojave Dome Fire
A 2020 fire in the Mojave Desert killed many Eastern Joshua trees, but researchers found that fungi and other soil microbes did not decline. The result affects how restoration might proceed.

Low pesticide exposure speeds aging in fish
Researchers found that long-term exposure to low levels of a common agricultural insecticide caused faster physiological aging and shorter lifespans in wild and laboratory fish. The study links telomere shortening and lipofuscin buildup to chlorpyrifos exposure.
Warmer temperatures make invasive brown anoles more aggressive
A Tulane University study found that rising temperatures increase aggression in invasive brown anoles more than in native green anoles. Researchers tested pairs of lizards in controlled enclosures and say warming could favour the invasive species.
Beaver mimicry to restore waterways
A Washington State University review finds that human-made beaver dams, or beaver mimicry, can help rivers and streams. The studies show benefits for water storage, cooler summer temperatures, biodiversity and fire resistance, but more research is needed.
