Perfluorooctane sulfonamide (PFOSA), a typical perfluorooctane sulfonate precursor (PreFOS), has been detected in the aquatic environment globally. However, the effects of PFOSA at levels measured in the environment have not been well characterized in aquatic organisms. In this study, we evaluated the transcriptional, biochemical, histopathological, and morphological...

Amy M. Gahala, Jennifer B. Sharpe, Andrew M. Williams
2023, Scientific Investigations Report 2023-5078
Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals that have been manufactured and used globally since the 1940s. PFAS are used for their oil- and water-repellent properties, ability to reduce friction, and their flame-retardant nature. PFAS are widely used in a variety of products, including clothing, carpet,...

Disparate data streams together yield novel survival estimates of Alaska-breeding Whimbrels
Daniel R. Ruthrauff, Christopher M. Harwood, T. Lee Tibbitts, Vijay P. Patil
2023, Ibis
Survival estimates are critical components of avian ecology. In well-intentioned efforts to maximize the utility of one's research, survival estimates often derive from data that were not originally collected for survival assessments, and such post hoc analyses may include unintentional biases. We estimated the survival of Whimbrels captured and marked at two...

Brian H. Robinson, Heather A. Coletti, Brenda Ballachey, James L. Bodkin, Kimberly A. Kloecker, Sarah Beth Traiger, Daniel Esler
2023, Marine Ecology Progress Series
The Pacific marine heatwave (PMH) of 2014-2016 was an intense, long-lasting environmental disturbance expressed throughout the north Pacific. While dramatic consequences of the PMH on pelagic food webs have been well documented, effects on nearshore food webs, i.e., those based on macroalgae primary productivity, benthic invertebrate intermediate consumers, and specialized...

Leaf nitrogen affects photosynthesis and water use efficiency similarly in nitrogen-fixing and non-fixing trees
Thomas A. Bytnerowicz, Jennifer L. Funk, Duncan N. L. Menge, Steven Perakis, Amelia A. Wolf
2023, Journal of Ecology
Nitrogen (N)-fixing trees are thought to break a basic rule of leaf economics: higher leaf N concentrations do not translate into higher rates of carbon assimilation. Understanding how leaf N affects photosynthesis and water use efficiency (WUE) in this ecologically important group is critical.We grew six N-fixing and four...
