Climate Changes and Zoonotic Epidemiology in Wildlife Systems (ZEWS)
This project aims to understand the dynamics of the plant root microbiome in response to elevated temperatures and altered annual precipitation patterns.
Climate warming is changing the timing of among others the reproduction for plankton or fish. Predators depend on an abundant prey supply to feed their young and insure that they survive. When the timing of the prey and the predator are not in synchrony the predator young cannot feed and are dying: there is a mismatch.
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.
Ozone on the ground level causes stress in natural vegetation. When the ozone level increases at the same time as the climate changes, vegetation is being hit by a double punch. This project seeks to find out how this affects the yield and growth.
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.
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?
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.
This project explores how climate change and other long-term environmental changes can influence the transport, uptake and food web transfer of mercury in boreal lakes.
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 and the effects of climate change present one of the greatest challenges of our time. It is a very broad research field which ignores the traditional boundaries between geoscience disciplines.
The Cryosphere includes all frozen water on the Earth's surface, all areas where snow, ice and permafrost affect the landscape and processes occurring there. We find a big amount of water tied up in glaciers and icecaps in Arctic and Antarctic, but also in permafrost and smaller glaciers worldwide.
Seabirds in Polar Regions are experiencing increasing environmental stress due to climate change and pollution. They also serve as indicator species for changes in the environment. But what do they tell us about how seabird populations are affected by contaminants and climate, and is the situation the same in Antarctica as in the Arctic?
The FLUFFY project aims to accelerate stationary energy storage research by developing cathodes for advanced sodium-ion batteries.
