Marine heatwave and keystone predator loss drive broad‐scale decline and hinder recovery of a rocky intertidal kelp

open access: yesEcological Applications, Volume 36, Issue 2, March 2026.
Abstract Human activities are increasingly driving the co‐occurrence of multiple ecological stressors, resulting in interactive and cumulative impacts that can reshape ecosystem dynamics and accelerate population declines of climate‐sensitive species. Here, we use over two decades of rocky intertidal monitoring data from 17 sites spanning over 1200 km ...

Metallothionein as an indicator of water quality: assessment of the bioavailability of cadmium, copper, mercury and zinc in aquatic animals at the cellular level [PDF]

open access: yes, 1994
The study of metallothioneins (MTs) has greatly improved our understanding of body burdens, metal storage and detoxification in aquatic organisms subjected to contamination by the toxic heavy metals, Cd, Cu, Hg and Zn.

On the Limits of Alpine Plants: A Systematic Review of the Factors Behind Species' Elevational Range Limits

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperature, while work at lower limits is more evenly distributed across water availability, plant–plant interactions, and selection/local adaptation.

Notes on the Mollusca from Site 41DT59, Cooper Lake, Delta County, Texas [PDF]

open access: yes, 2000
This paper focuses on the information about the mollusca from site 41DT59. The author takes the information from Dr. Fullington, the noted malacologist, and illustrates how the archeologist can take the information and apply it to site analysis.

Multiscale Threats Shape the Occurrence Dynamics of a Threatened Aquatic Salamander and Reveal a Possible Extinction Debt

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
The Neuse River Waterdog (Necturus lewisi) is a threatened large aquatic salamander endemic to North Carolina, USA. Site‐specific habitat quality, the proportion of developed landcover in the watershed, and annual drought intensity operate in concert to drive the species' occurrence dynamics.

Applying Environmental DNA Metabarcoding to Calculate an Index of Biotic Integrity for Freshwater Fish

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
We used eDNA metabarcoding to calculate a fish‐based IBI and compared our eDNA‐IBI to a previously implemented fish‐IBI for the Tennessee River basin in northern Alabama. We found significant, positive relationships between the eDNA‐IBI and fish‐IBI, but we discuss how future directions may improve eDNA‐IBIs.

Freshwater immersion as a method to remove Urosalpinx cinerea and Ocinebrellus inornatus from mussel seed [PDF]

open access: yes
A simple experiment to test whether immersion in freshwater for ≤24 hours would kill two oyster drills, Urosalpinx cinerea and Ocinebrellus inornatus was conducted to test the proposal of using freshwater to rid mussel seed of the drills before ...

A Freshwater Pearl Mussel Polysaccharide Alleviates Inflammatory Pain by Targeting Peripheral Cytokines and Spinal Astroglial NLRP3/GFAP Responses

open access: yesFood Science &Nutrition, Volume 14, Issue 3, March 2026.
Mussel polysaccharide (MP), a novel food resource from pearl mussels, alleviates inflammatory pain in rats in a dose‐dependent manner. It acts by dually inhibiting peripheral inflammation (reducing paw swelling and pro‐inflammatory cytokines) and spinal neuroinflammation via the NLRP3 and astrocyte pathway.

Contaminants in Unionid Mussels from the Confluence of the Mississippi and Illinois Rivers [PDF]

open access: yes, 2008
Unionid mussels were collected from three mussel beds near the confluence of the Mississippi and Illinois rivers in 2003 to evaluate concentrations of selected elements and organic compounds in three abundant species and to preliminarily investigate the ...
