Weak effects of local prey density and spatial overlap on predation intensity in a temperate marine ecosystem Open
Quantifying the impact of lower trophic level species abundance on higher trophic level predators (and vice versa) is critical for understanding marine ecosystem dynamics and for implementing ecosystem‐based management. Trophic ecosystem m…

Reduced size of larvae and small fish linked to warming and reduced prey density Open
Body size is a integrative trait that has declined across ecological assemblages in the last decades. Changes in body size of early life stages and small-bodied fish are driven by complex interactions between size-dependent mortality, and …

Occurrence and Strength of Instantaneous and Intracohort Density‐Dependence in Northeast Atlantic Fish Stocks Open
Biological reference points (BRPs) used in fisheries management do not include density‐dependent (DD) growth, with DD processes only considered in the stock recruitment relationship. Not accounting for DD on somatic growth has led to criti…
