Tapeworm Parasite Burden Is Linked to Diet, Body Size, Condition, Growth, Restocking and Habitat Use in Piscivorous Salmonids of a Subarctic Lake

open access: yesEcology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Parasites affect hosts in interaction with the entire ecological community. This is particularly evident for trophically transmitted parasites, such as Dibothriocephalus tapeworms, which infect multiple intermediate fish hosts, potentially reducing their fitness and suitability for human consumption.

The revision of baphetids from the Middle Pennsylvanian of the Czech Republic: Morphology, ontogeny, palaeoecology, and the reassessment of the phylogeny of Baphetoidea

open access: yesThe Anatomical Record, Volume 309, Issue 7, Page 1766-1787, July 2026.
Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...

Environmental DNA as a Detection and Quantitative Tool for Brown Bullhead Catfish (Ameiurus nebulosus): A Comparison With Conventional Netting

open access: yesEnvironmental DNA, Volume 8, Issue 4, July‐August 2026.
Multiple environmental DNA (eDNA) methods were compared with each other and with fyke netting for detecting invasive brown bullhead catfish. eDNA sampling combined with catfish‐specific metabarcoding provides sensitive detection and effectively complements traditional netting for biosecurity.
