A recently paper published in PNAS,  members of the CEES Marine Group explore potential climate effects on Calanus finmarchicus, a key zooplankton species in the North Atlantic. The paper shows how the combination of shallow mixed-layer-depth and increased wind apparently increases chlorophyll biomass in spring, and in turn C. finmarchicus biomass in summer. These findings strongly suggest bottom-up effects of food availability on zooplankton, and highlight the need to consider climate effects “beyond temperature” when projecting zooplankton dynamics under climate change.

Marine phytoplankton contribute nearly 50% to global primary production, support zooplankton production and play a vital role in regulating Carbon sequestration. Phytoplankton productivity fluctuations are caused by various direct and indirect effects of temperature, the balance of which show large-scale geographical patterns.

Penguins are highly visible species for the public. Their life has been portrayed in many movies. Unfortunately they are also species impacted by climate change. In a recent publication a team led by Charles Bost used long-term data to relate the large-scale climatic anomalies in the Southern Hemisphere to the foraging behaviour and population dynamics of the king penguin.

In this study we assessed the chances of recovery of the Baltic Sea cod stock and conclude that it will never come back to the status it had more than three decades ago and that the economic losses associated to this new baseline amount to 120 million euros per year.

Much of our present knowledge on the ecology and behaviour of animals is derived from longitudinal studies of individuals using long-term datasets. The collection of such datasets requires the ability to identify individuals repeatedly over time, i.e. by individual markings. Here comes the problems for Penguins.

Europe and other funding agencies are very attentive to interdisciplinarity and trans-sectoral activities. Their ever growing demand for multi- and trans-disciplinary science is reaching such a level that making Ecology and getting funding for it becomes a challenge. Is there a way around it?

Some while ago a student asked us if we were collecting data in the marine ecological group at CEES. We were forced to acknowledge that we were not.  From this follows a real cri de coeur: “but we are only scavengers!” Are we really? If we are, is it all bad?

Increased sea temperature due to climate change can influence the distribution, abundance and seasonal timing of zooplankton. Changing zooplankton dynamics might in turn impact the higher trophic levels, such as fish and seabirds, feeding on these animals. In a recent paper, we show that temperature variation in the Atlantic waters of the Norwegian Sea and Barents Sea might have stronger effects on the abundance of the younger than older development stages of Calanus finmarchicus, and that these stages might appear earlier in spring during warm years.

Climate change is thought to change many aspects of the marine life. Among others, one can mention changes in species distribution (immigration of species; new species coming to northern areas), the rate of development (warmer the temperature, the faster is the development), and change in the timing of the reproduction. The latter has recently caught a lot of attention around a nearly 50 years old hypothesis of the British fisheries biologist David Cushing.

Climate change, and especially alteration in sea temperature, is expected to have major effects on the distribution and abundance of marine fish. This is in particular the case in northern high-latitude marine ecosystems, where IPCC expects global warming to be especially pronounced.

There are, unfortunately, no master projects available at this stage!

The project “Effects of Neonicotinoids and Temperature on Crop Pollination (NEOPOLL)” is a ~4 year Researcher project awarded Anders Nielsen (PI) over the Miljøforsk program at the Norwegian Research Council. The project started in April 2017. There are several master students involved in the project, investigating different aspects of how neonicotinoids affect bumblebee behaviour and colony development, but also more ecotoxicological approaches related to pesticide accumulation in nectar, pollen and bumblebees.

The NEOPOLL project, funded by the Research Council of Norway, is moving. Julie Sørlie Paus-Knudsen has been hired as a PhD student and started December 1th 2017. In addition we have taken on two master students (Pawel Jan Kolano and Malin Aarønes) to work on the project.
