Assessing the Acute and Chronic Effects of Palladium on Daphnia magna and the Influence of Natural Organic Matter

open access: yesJournal of Applied Toxicology, Volume 45, Issue 11, Page 2363-2377, November 2025.
ABSTRACT In recent decades, rising industrial demand for palladium (Pd), driven by its unique properties and affordability compared to other noble metals, has increased its environmental release into aquatic systems. This highlights the need to assess its effects on organisms, given the lack of standardized toxicity studies and regulations for this ...

Testing non‐lethal techniques for endoparasite detection and sex determination in pumpkinseed sunfish (Lepomis gibbosus)

open access: yesJournal of Fish Biology, Volume 107, Issue 2, Page 406-418, August 2025.
Abstract Developing non‐lethal techniques to estimate parasite infection is critical for studying disease ecology in wild animals. We tested the effectiveness of coelomic ultrasonographic examination and plasma enzyme markers to detect liver infection with bass tapeworms Proteocephalus ambloplitis (Leidy 1887) as well as the effectiveness of ultrasound

Local environment and sampling bias drive parasite prevalence estimates in freshwater fish communities

open access: yesOikos, Volume 2025, Issue 7, July 2025.
Parasite occurrence and infection estimates vary through time and space, making understanding the underlying drivers highly complex. Comparative studies based on empirical data must consider the factors of variation involved in estimating infection metrics in natural populations to make appropriate and reliable comparisons. Using a multi‐scale approach,
