Animals within social groups respond to costs and benefits of sociality by adjusting the proportion of time they spend in close proximity to other individuals in the group (cohesion). Variation in cohesion between individuals, in turn, shapes important group‐level processes such as subgroup formation and fission–fusion dynamics. Although critical to animal sociality, a comprehensive understanding of the factors influencing coh...

Many of the world's fisheries are unassessed, with little information about population status or risk of overfishing. Unassessed fisheries are particularly predominant in developing countries and in small‐scale fisheries, where they are important for food security. Several catch‐only methods based on time series of fishery catch and commonly available life‐history traits have been developed to estimate stock status (defined as...

The distribution of infectious salmon anaemia (ISA) was examined among 80 cages from three Atlantic salmon grow‐out farms in Maine, USA that were stocked with smolts from a single hatchery. Cage‐level disease was broadly defined as one or more moribund fish testing positive for infectious salmon anaemia virus (ISAV) by RT‐PCR and a second confirmatory test (IFAT, culture or genotype sequence). Spatio‐temporal and cage‐level ri...
