Potential Trophic Competition Between the European Perch Perca fluviatilis and Pikeperch Sander lucioperca

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT The European perch Perca fluviatilis and pikeperch Sander lucioperca can co‐occur, potentially competing for food resources. However, few studies have addressed the potential feeding competition between these species. We used carbon and nitrogen stable isotope analysis to assess the potential trophic competition between these species in two ...

Juvenile and Adult Three‐Spined Sticklebacks Exhibit Different Habitat Use in Shallow Baltic Sea Bays

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Three‐spined sticklebacks (Gasterosteus aculeatus) have become dominant in many Baltic Sea coastal fish assemblages, yet life‐stage‐specific habitat use remains poorly understood. We surveyed shallow water habitats along the coast of Gotland, Sweden, to examine how juvenile and adult stickleback abundances relate to variables such as submersed

Heavy Metal Contamination in Two Tilapia Species (Oreochromis macrochir and Coptodon rendalli) From the Kabompo River, Zambia: A Food Safety and Human Health Risk Assessment

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Aquaculture sustainability is threatened by heavy metal contamination, particularly in regions where rivers are the primary water sources. The present study assessed the concentrations of cadmium (Cd), cobalt (Co), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn) in two key aquaculture species, Oreochromis macrochir and ...

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, Volume 309, Issue 4, Page 864-911, April 2026.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Reduced sediment accumulation rate enhances early marine diagenesis of periplatform sediments

open access: yesThe Depositional Record, Volume 12, Issue 2, April 2026.
The influence of reduced sediment accumulation rate on early marine burial diagenesis was investigated in sediments collected by ODP Leg 133. Results show that low sediment accumulation rates can produce substantial and asynchronous shifts in stable carbon isotope ratios across a slope transect without the development of sedimentological indicators of ...
