In a study recently published in Ecology we find apparent competition between major zooplankton groups in a large marine ecosystem. Apparent competition is an indirect, negative interaction between two species or species groups mediated by a third species other than their prey.

The Norwegian coast is a spawning hot spot for several highly valuable fishes. After hatching, the young fish drift, largely together, toward the Barents Sea. During this drifting period, they need to feed and are experiencing predation. In a paper published in Marine Ecology Progress Series (Ferreira et al. 2024) we explore the benefits and disadvantages of drifting together with other larvae.

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.
