Allelopathy and potential allelochemicals of Ligularia sagitta as an invasive plant [PDF]

open access: yesPlant Signaling and Behavior
Allelopathy is the main chemical means in the invasion process of exotic plants and one of the key factors in grassland degradation. In this experiment, we investigated the effects of ethyl acetate phase extract (EAE), n-butanol phase extract (BE) and ...

Functional Morphology of the Oral Jaws and Dentition Across Diverse Diets and Ontogeny in Prickleback Fishes (Stichaeidae). [PDF]

open access: yesJ Morphol
Prickleback fishes (Stichaeidae) feed upon diverse diets, spanning carnivory (orange), omnivory (blue), and herbivory (green). We used microCT scanning to explore the functional morphology of the oral jaws and dentition across species and ontogeny. Focal species vary by morphotype and have divergent scaling patterns across diets.

Glass eels and viruses – a lesson learnt from stocking the eastern German Baltic Sea coast

open access: yesTransboundary and Emerging Diseases, Accepted Article., 2022
Abstract Concerns about Anguillid herpesvirus 1 (AngHV‐1) in European eels, especially due to stocking measures, is increasingly coming into focus and raises questions regarding disease monitoring and prevention. In the past, stocking of AngHV‐1‐positive eels into waters assumed AngHV‐1‐free has led to a rapid increase of infected eels in the wild. For
