Environmental science writer, press officer, pro #scicomm -er for UC Davis. Covering climate change, ecology, conservation, water and wildlife. My other brain is full of paint. Views my own.

People say summer is "slow" for university press officers, to which i just laugh. A few things that popped up for me today: harbor seals, bedbugs, sharks, prescribed fire, avocado sex, dry wetlands, snowy plovers, neanderthals and fog. Not complaining. 🦈🔥☀️🥑🪲🦭❤️

Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

Balanced polymorphism in a floral transcription factor underlies the ancient rhythm of daily sex alternation in avocado | PNAS

In avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...

Remember those extreme wildfires in 2020 and 2021 that set many of CA's giant sequoias ablaze? It would have been about 4x worse without the prescribed burns some groves got within the previous decade. Another study from @ucdavis.bsky.social showing Rx burns work. www.ucdavis.edu/climate/news...

Prescribed Burns Saved Thousands of Giant Sequoias

When two major wildfires burned through the Sierra Nevada in 2020 and 2021, they took thousands of giant sequoia trees with them. Without prescribed burns, thousands more would have died, according to...

“We found that what causes extinction is not that plants aren’t moving fast enough,” said senior author Xiaoli Dong. “It is that a large amount of suitable habitat by the end of the century is going to be gone." www.ucdavis.edu/climate/news...

Study Projects Plant Extinction Rates Through 2100

A UC Davis study in Science found that 7% to 16% of global plant species studied face high risk of extinction by 2100 under current climate change projections.

When wildfires burn study sites or funding freezes, our researchers don’t quit, they pivot. From tracking megafire impacts to discovering coral reef resilience, they turn setbacks into breakthroughs for our changing world. Learn about how they overcome the challenges they face: ucdav.is/3OqIgQQ

"Maybe we need to rethink how we still do the right things.” Scientists are open to what shows up, not always what is planned. But stable support is required for inquiry to flourish. 4 stories of people trying to turn setbacks into science. @ucdavis.bsky.social www.ucdavis.edu/climate/news...

Stop-and-Go Science: Researchers Pivot to Try to Salvage Important Work

When climate change is faster than the speed of science and unstable funding threatens discovery, UC Davis scientists pivot to try to save important research.

CA has some of the highest wildfire-driven forest losses in the world, yet reforestation efforts fall far behind the rate of loss, a @ucdavis.bsky.social study finds.🔥🌲 🌎https://www.ucdavis.edu/climate/news/wildfire-driven-deforestation-rates-california-among-highest-world

Wildfire-Driven Deforestation Rates in California Among Highest in World

California has one of the highest rates of wildfire-driven deforestation in the world, and the trend has accelerated over the past three decades, according to a UC Davis study.

From "cattle vision goggles" to goat-handling machines that let the animals "be with a friend," our latest episode explores new tools to help people see how livestock perceive their world, helping them and the people who raise them. Listen now! @katkerlin.bsky.social www.ucdavis.edu/news/podcast...

Where Science Meets the Herd

We put on a pair of “cattle vision” goggles to see how livestock perceive their world. Learn why understanding that is better for the animal and the rancher.
