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

open access: yesJournal of Fish Biology, EarlyView.
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

Drivers of the range expansion of the European catfish (Silurus glanis) within its native distribution

open access: yesJournal of Fish Biology, EarlyView.
Abstract The European catfish Silurus glanis L. continues to spread as an invasive species in Europe. Meanwhile, increasing abundance and range expansions are also suspected within its native distribution. The objective of this study was to characterize the feeding, growth and abundance of S.

Diplostomum‐Induced Sac Formation in Lenses of Ameiurus Bullheads: A Host Defence Response?

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Trematodes of the genus Diplostomum (Diplostomidae) are widely distributed and significant fish pathogens known for causing a range of negative effects. Any mechanism that protects the host from the parasite thus represents an evolutionary advantage.

Understanding marine biodiversity patterns and drivers: The fall of Icarus

open access: yesMarine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.
