Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

Journal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Global length–weight relationships of deep‐pelagic fishes: Coverage, biases and variability

Journal of Fish Biology, EarlyView.
Abstract Length–weight relationships (LWRs) are morphometric tools that allow body mass to be estimated from fish length, providing input for fisheries, ecological and biodiversity studies. For deep‐pelagic fishes, however, LWR data remain fragmented and unavailable for most species.

Shaping the System Through Turbulence: Strategic Leadership and the Micro‐Foundations of Ecosystem Orchestration in Times of Disruption

Journal of Management Studies, EarlyView.
Abstract While research on ecosystems and their orchestration has grown rapidly, we still know little about how individual strategic leaders may mobilize ecosystemic action in times of disruption. This article addresses this gap by drawing on an in‐depth case study of the Antwerp Square Mile, the world’s oldest and most renowned diamond trading ...

Are Firms Ready for Workforce Ageing? Evidence From Small‐Medium Sized Firms in Italy

LABOUR, EarlyView.
ABSTRACT We investigate age‐related human resource management (AR‐HRM) practices within SME in Italy. Using firm‐level survey data with information on age‐related attitudes and practices, we analyze the determinants of age management and outplacement practices, along with the role of collective bargaining.
