For the second year, we have been invited to guest lecture for students in the Arctic Population Ecology (AB-204) course led by Dr. Larissa Beumer at the University Centre in Svalbard (UNIS). Our theme for the guest lectures was marine ecology and how we can use tracking methods like acoustic telemetry to study the behaviour and movement of aquatic species. In addition to lecturing about telemetry methods, we showed examples of research projects where telemetry is used, ethic

Alpine lakes are among the most climate-sensitive ecosystems on Earth. As temperatures rise, cold-adapted species face increasing pressure, and key ecological processes begin to shift. Yet these lakes also offer a unique opportunity: they act as natural laboratories where we can study how freshwater ecosystems respond to environmental change. Finsevatn (Finse lake), located in the high mountains of southern Norway, is particularly well-suited for this kind of research. Finsev

This year’s fieldwork in spectacular Svalbard for the NICE project is finalized. Two field campaigns, one during summer and one during fall, have been conducted by PhD candidate Saron from the BTN team as well as many researchers from the collaborating partners. The fieldwork in Svalbard offers quite challenging conditions given its location in the high Arctic, however with amazing views. The work is part of the NICE project, which investigates how climate change is reshaping

As the main bulk of field work in BOATS and PUFFINS is coming to a close, we look back at lovely days at Puddefjorden and Store Lungegårdsvannet which can only be described with one word: successful. This season kicked off in June by downloading data and changing batteries in all receivers. Also in June, we deployed three additional receivers to the Store Lungegård network. After the summer break our fishing efforts began. This year, we weaved together fyke nets with only one

We’re thrilled to announce that BTN will receive funding for two major research projects through the Norwegian Research Council (NFR). These projects - CARE-COD and ROPES - will deepen our understanding of how marine ecosystems respond to rapid environmental change, from the high Arctic to the fjords of western Norway. CARE-COD: Cod Evolution in a Changing World The CARE-COD project turns its lens to the Atlantic cod, a species central to Norwegian fisheries and now facing t
