Lake Tahoe Algae Experiment Suggests Seasonal Shifts Ahead

Katherine E Kerlin — October 06, 2025 - 9:06am

As the climate warms and nutrient inputs shift, algal communities in cool, clear mountain lakes like Lake Tahoe will likely experience seasonal changes, according to a study from the ɫ��ɫ.

Periphyton, that fuzzy layer of attached algae covering the rocks as you step into the water, is a healthy and critical part of a lake’s food web. Periphyton blooms, however, signal changes that can degrade both water quality and a shoreline’s natural beauty.

An interdisciplinary team of public health and environmental science researchers from across the University of California have found that despite efforts by the state and local school districts, many public schools fall short of providing sufficient shade, much less natural playing surfaces, for the 5.8 million children they serve — especially in an era of extreme temperatures.

A tiny fish with transparent embryos is helping ɫ��ɫ, researchers shed light on how exposure to crude oil and flame retardants can affect behavior, skeletal growth, cardiac health and other internal functions in offspring and subsequent generations.

The research on multiple generations of Atlantic killifish (mummichogs) was published across three papers in the journal Environmental Science and Technology.

Air quality scientists have detected elevated levels of hexavalent chromium and silver in air samples collected from the debris cleanup zones for the Eaton and Palisades wildfires, which occurred January 2025 in Los Angeles County.

Arctic Reindeer Could Decline by 80% by 2100

Katherine E Kerlin — August 15, 2025 - 2:29pm

Researchers predict that future climatic change is likely to cause declines in reindeer abundances and their distribution at rates rarely seen over the last 21,000 years.

Reindeer, also known as caribou in North America, are an Ice Age species that have survived many episodes of Arctic warming. They are uniquely adapted to Arctic environments, where they regulate ecosystems and sustain the livelihoods of many Indigenous Peoples.
