Integrating Plant Volatile Scents in Sustainable IPM Approaches for Fall Armyworm Control

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Since the invasion of the fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae) into new regions, studies have oriented toward low‐cost management tools and methods. This study assessed the effects of volatile scents that are naturally emitted by essential oil (EO) plants on the severity of FAW and populations of its natural ...

A common garden experiment in the wild reveals heritable differences in migration tendencies among brown trout populations

open access: yesJournal of Fish Biology, EarlyView.
Abstract We undertook a common garden experiment in the Burrishoole catchment, western Ireland, to test for heritable life‐history differences among neighboring brown trout (Salmo trutta L.) populations that exhibit neutral genetic divergence. Experimental crosses were made using either local females (obtained from a below‐waterfalls section of the ...

Morphological and metabarcoding dietary analysis of the cunner wrasse (Tautogolabrus adspersus) revealed significant regional variation, with large overlap between its common prey species and biofouling animals living on salmonid sea cages

open access: yesJournal of Fish Biology, EarlyView.
Abstract The stomach‐less cunner wrasse (Tautogolabrus adspersus) has been experimentally used as a biological control agent for salmon lice that infest Atlantic salmon (Salmo salar) and to remove biofouling inside sea cages. The cunner demonstrates a strong population structure, suggesting that its diet, and therefore its usefulness for biological ...

Improving eel pass efficiency: The role of crest shape and water flow in facilitating upstream juvenile eel migration

open access: yesJournal of Fish Biology, EarlyView.
Abstract River connectivity is crucial for the European eel (Anguilla anguilla) to complete its complex life cycle, which is vital for upstream recruitment to the declining population of this critically endangered catadromous fish. Eel passes, or ladders, are frequently installed on riverine structures, such as dams and weirs, to mitigate barrier ...
