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+!

#PFAS are widespread in modern society, including in many agricultural settings.

Our new report examines ways to mitigate the impacts of these #ForeverChemicals on human and ecological health and strengthen conservation planning.

Scientific fraud has become an ‘industry,’ alarming analysis finds Sophisticated global networks are infiltrating journals to publish fake papers

A new study, based on an analysis of thousands of publications and their authors and editors, shows paper mills are just part of a complex, interconnected system that includes publishers, journals, and brokers. scim.ag/3H9kwwQ

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.

Denitrification Looks Different in Rivers Versus Streams - Eos A study directly comparing waterways of different sizes revealed important differences in nitrogen dynamics across seasons.

Rivers and streams each help remove excess nitrogen from surface waters, but there are important differences between them. New research by @abagaelpruitt.bsky.social, @ajreisinger.bsky.social, and coauthors in new @jgrbiogeo.bsky.social research.

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!

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.
