A Meta‐Analysis on Environmental Triggers of Spawning Migrations Reveals a New Classification of Thermal Guilds in European Freshwater Fishes

Fish and Fisheries, EarlyView.
ABSTRACT Fish migration through river networks is essential for completing life cycles and accessing critical habitats, but fragmentation increasingly disrupts spawning movements. In Europe, over one million barriers limit connectivity and create trade‐offs between ecological integrity and human uses, such as hydropower, flood control, fisheries and ...

Morphometric and External Injury Characterization of Rainbow Trout (O. mykiss) Used for Stocking in the Alpine River Inn (Bavaria, Germany)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

Beyond Exceptional and Ordinary: Analysing the Effects of Emergency Frames on EU Renewable Energy Policy‐Making

JCMS: Journal of Common Market Studies, EarlyView.
Abstract This study aims to provide a better understanding of how policy‐making changes when an issue is framed as an emergency. Literature on emergency politics provides different views on policy‐making changes resulting from emergency frames, where ordinary and exceptional policy‐making overlap in different ways.
