#idw #Climate Marine heatwaves pose problems for coastal #plankton
Temperatures around the world continue to rise – and the #NorthSea is no exception. Yet, in addition to this gradual #warming, increasingly frequent and intense heat events also have consequences for marine organisms. When heatwaves are added, however, these alterations are amplified. The results have been published in three publications, most recently in #Limnology and #Oceanography.

Highland springs, north Iceland.
Underground streams break out from underneath leaky strata. In this case ice-age moraines, but in others lavafields.
The springs harbour live and the underground rivers have microorganisms and top predator in small freshwater amphipods
Only endemic invertebrates in iceland, that have lived through couple of Ice-ages (>5 million years)

Ice (Glaciology 🗻)
Ice is water that is frozen into a solid state, typically forming at or below temperatures of 0 °C, 32 °F, or 273.15 K. It occurs naturally on Earth, on other planets, in Oort cloud objects, and as interstellar ice. As a naturally occurring crystalline inorganic solid with an ordered structure, ice is considered to be a mineral. Depending on the presence of impurities such as pa...

Trophic interactions determine food web structure and influence biodiversity, community structure, ecosystem functioning, and food web responses to global change. These interactions are highly flexible, changing on temporal scales from diurnal to evolutionary times due to phenotypic plasticity, rapid evolution and species sorting. Small-scale experimental and theoretical studies of plankton interactions have demonstrated a high relevance of this flexibility for community dynamics and ecosystem processes in small, simplified communities. However, the extent to which this flexibility affects larger-scale systems, for example, global ocean dynamics and their responses to global change, is still poorly understood. Differences in methodology, focus and terminology between research disciplines limit our ability to project established effects of flexible trophic interactions onto larger spatial and temporal scales. We propose to bridge this gap with a general framework for upscaling knowledge from small-scale research to large-scale models. Building on examples from plankton communities, we use this framework to show how mechanisms demonstrated in small-scale studies can be linked to ecosystem functions relevant at large scales. We argue for incorporating flexibility in large-scale process-based models to improve their realism and predictive power, and discuss challenges and ways forward for achieving this. Finally, we suggest several concrete ways for upscaling small-scale studies to make their findings more relevant for large-scale research, to close existing knowledge gaps and to improve our understanding of how flexible trophic interactions affect dynamics and processes across scales.

Where do the charr go, when climate change hits their rivers?
Writing a small grant for a summer project
2 students 1 M icelandic crowns for each
(Pititful salay if you ask me)
Anadromous charr spawn in rivers, but we mainly find the fry in side streams
Want to map that more carefully,
Find most preferred streams
