- Post Doc in invertebrate ecotoxicology available at University of Oslo, Norway! We have a 3.25 year post doc position available in our MULTISTRESS group on invertebrate ecotoxicology focussing on the interaction between climate change and toxicity of pesticides. www.jobbnorge.no/en/available...
- The Post Doc postion in part of our new Norwegian Research Council funded project SoilStress where we address mechanisms underlying cumulative effects, recovery, and ecophysiological tipping points from multiple stressor disturbances (climate change and pollution).
- We will study complex questions of WHY key biological responses to multiple stressors (climatic stress and agricultural used pesticides) differ between populations, micro-climate, and climatic regions; WHY tolerance to pesticide exposure decreases with temperature stress; and

- When the ocean breathes in the cold 🥶 (-20 °C), snow dances across the deck, the moon lights our way, and we sample zooplankton in the heart of the Arctic polar night.
- It was an epic expedition to the dark and frozen Nansen Basin. Working in air temperatures below -20 °C with biting wind, we deployed Mammoth and MIK nets to 4000 m depth in the Arctic Ocean. Sampling during this special time of year taught me far more about zooplankton communities than I expected.

View full threadGrateful to the amazing crew and scientists who made this polar night adventure possible. The Arctic never ceases to amaze, especially when I know more about how busy it is below the silent ice.
- A mammoth net hauls zooplankton from 4000 m depths in the Nansen Basin—under -20 °C air and howling winds.
- Heading North for the overwintering organisms in the dark of the Arctic (polar) nights!
- Happy to share our latest paper: "Sea surface freshening can suppress the thermal tipping point of marine copepods" in Science of the Total Environment! 🌊❄️ We found that: 1) Survival of Calanus copepods tipped and decreased above temperatures of 14–18 °C. #ClimateChange #MarineEcology #OceanWarming
- 2) At 29 PSU, this corresponded to a tipping point of heat accumulation of 28 °C.d above which survival decreased. 3) Reduced salinity below 29 PSU, prevalent year-round in surface waters, suppressed this tipping point, inducing linear decreases in survival when temperature rises above 8 °C.
- We provide the first statistical determination of heat accumulation tipping points. We also demonstrate that exposure to a secondary stressor can suppress tipping points to a primary stressor, thereby removing the ability of phenotypic plasticity to buffer negative impacts on fitness.
- Huge thanks to master's student Andrea for conducting the experiments, postdoc Mathieu for leading the writing, and all collaborators for making this possible!

- "During the workshop, Khuong Dinh (University of Oslo), an ecotoxicologist, raised a simple question to everyone, ‘How do you define biodiversity?’ As it turned out, everyone had a slightly different answer."
- " While the legal scholars pulled up the definition of biodiversity in international legal conventions, the anthropologists and historians started talking about how biodiversity is vernacularly understood and how the term itself is linked to some historical relation of power and domination."
