Enemy release: loss of parasites in invasive freshwater bivalves Sinanodonta woodiana and Corbicula fluminea

open access: yesEcography, Volume 2026, Issue 8, August 2026.
Invasive freshwater bivalves harm native species, ecosystems and biodiversity, and incur economic costs. The enemy release hypothesis posits that invasive species are released from enemies during the invasion process, giving them a competitive advantage in the new environment.

Quantifying Colonisation Pressure as a Driver of Secondary Spread During the Dreissena polymorpha Invasion of German River Networks

open access: yesFreshwater Biology, Volume 71, Issue 8, August 2026.
ABSTRACT Biological invasions have become a major component of global change, yet the processes governing secondary spread after initial introductions remain insufficiently resolved. A specific and central gap is the lack of a spatially explicit and temporally dynamic quantification of colonisation pressure, despite its presumed importance for ...

Interactive effects of rearing densities and dietary vitamin E levels on growth, stress, and immune responses, and antioxidant status in triploid rainbow trout (Oncorhynchus mykiss)

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract This study aimed to evaluate the interactive effects of rearing densities and supra‐nutritional levels of vitamin E on fish performance. Triploid rainbow trout juveniles (40.44 ± 1.27 g) were distributed into 18 tanks at medium (MD, 30 kg/m3, 45 fish/tank) and high (HD, 60 kg/m3, 90 fish/tank) densities.

Increased Expression of miR‐326 Mediates Chemosensitivity in Pediatric Acute Lymphoblastic Leukemia Through ABCA2 and YY1 Downregulation: An Observational and Experimental Study

open access: yesHealth Science Reports, Volume 9, Issue 7, July 2026.
ABSTRACT Background and Aims Multidrug resistance (MDR) is a major determinant of relapse‐associated mortality in pediatric acute lymphoblastic leukemia (pALL). Although miR‐326 downregulation has been associated with poor prognosis, its role in chemoresistance remains undefined. This study investigated the mechanistic contribution of miR‐326 to MDR in

Temperature‐driven diet shift in an invasive omnivorous crustacean feeding on plankton

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Global warming alters the physiology of ectotherm consumers, potentially making their diets more herbivorous. However, the relevance and generality of these changes remain poorly understood in a multispecies context. To address this critical knowledge gap, we experimentally tested the temperature‐dependent feeding preference of the invasive ...
