Understanding the changes in population abundance is essential to correctly manage and preserve the natural populations. Interaction between species, such as predation or competition, is an important factor affecting population dynamics. To understand population dynamics it is thus useful to study species interactions. In a recent study published in Biology Letters, we analysed the interaction between two iconic fish species of the Barents Sea: the capelin and the Atlantic cod.
Population abundance depends on production of young and survival of adults. Assessing the contribution of young production to population growth and identify the main drivers of its variability may help to identify appropriate stock management measures. What happens when several stocks, belonging to different trophic levels and habitats, as well as having different exploitation histories are sharing the same environment?
Conventional fishing management by governmental regulation often oversimplifies the complex interplay of power relationships between fishers and other stakeholders. In a recent study published in Ecology and Society (Kininmonth et al. 2017), we looked how the fishing-traders relationships may affect fishing patterns in light of market or ecological changes.
