Swimming invasive snakes colonize Mediterranean islets by active swimming, then wipe out Endangered endemic lizard populations. A hidden pathway for biological invasions with profound conservation implications, as they re-shape island ecosystems 🐍 🌊 #OpenAccess in 'Ecology' Picture: Rubén Casas

Thrilled to share that my first dissertation chapter is now published at Ecology! dx.doi.org/10.1002/ecy.... We embed TPCs into population dynamics to show how changing temperatures' ordering — not just its distribution — increases extinction risk (i.e. heatwaves matter!) @esajournals.bsky.social

If you can't beat 'em, eat 'em? Really? Our new opinion piece in @pnas.org defends that the so-called invasivorism is not an effective management strategy. In most cases, it is not even a strategy Great team, led by @oficialdegui.bsky.social @ebdonana.bsky.social www.pnas.org/doi/10.1073/...

The warm winter has left very little snow in California’s Sierra Nevada, and now an extreme heat wave is accelerating the rapid melt in the mountains. I spoke with @newshaajami.bsky.social about what warming winters mean for the future of California's water: www.latimes.com/environment/...

Here are a few pupfish moments of zen from the newly opened Salt Creek Boardwalk. Literally opened only 3 days ago. We saw thousands of these relicts from pluvial Lake Manly swimming in the salty spring water. They can survive salinities over twice that of seawater and temps from 32F to 100F+!

New research on the variable relationship between rivers' flow regimes and their ecosystems—in our journal "Ecological Applications"👇

Diapausing eggs are a key element in this research, as they represent a fundamental adaptive strategy for the survival and persistence of species in the face of adverse environmental conditions and they can only be produced sexually.

Protection is overwhelmingly driven by land-based mechanisms, which are often spatially misaligned with hotspots of freshwater biodiversity and may inadequately safeguard rivers from upstream threats. Protection is also uneven across river types (intermittent rivers less protected) and geographies.

This summer, American Rivers began a multi-year effort with @yubariverpeople.bsky.social and the U.S. Forest Service to find out how many "lost meadows" there really are in California's North Yuba watershed. The results are surprising! 🌾 Read our findings: www.americanrivers.org/2025/11/redi...

As dozens of frog species have declined across Central America, scientists have witnessed a remarkable chain of events: With fewer tadpoles to eat mosquito larvae, rates of mosquito-borne malaria in the region have climbed, resulting in a fivefold increase in cases. https://wapo.st/4paBuuT

We also found that fishes are accumulating risk faster than their zooplankton prey during key times of year. A pattern that hints at the potential for trophic mismatches that could affect the whole food web. We also found strong spatial patterns, with the strongest divergence in more saline regions.

By modeling how long-term population trends and variability impact decline probability, we examined how risk fluctuates throughout the year for age-0 fishes. We found that risk can vary from month to month, highlighting that risk might not be consistent even within the same life stage.

So excited to share our new paper out today in Ecological Applications @esajournals.bsky.social! We used time-series modeling explore ecological risk for fishes and their prey in the San Francisco Estuary during key phenological windows that shape food web dynamics. dx.doi.org/10.1002/eap....

How vulnerable are riparian trees to drought? Using groundwater and satellite data from a California waterhsed, our new paper found that trees by drying rivers lost up to 5 weeks of growing season, suggesting they’re nearing critical groundwater limits. onlinelibrary.wiley.com/doi/10.1111/...
