NEW! COAT CASE STORY

Long time series are important for understanding changes in nature. Despite extensive research on vegetation in Svalbard, long-term monitoring has been lacking. But we can now present “Year 1” of Svalbard vegetation monitoring within COAT.

This year's snow measurements in Komagdalen and Vestre Jakobselv have been carried out

Snow measurements are an important part of the monitoring done in COAT – snow is indeed an important driver of many processes underlying dynamics of arctic ecosystems. The measurements we do focus on simple measurements of snow depths in different habitats (snowbeds, hummock, meadow, heath), as well as much more detailed assessment of the different...

Graphical abstract describing the approach used to study population dynamics of Svalbard ptarmigan. First, researchers carefully laid out the hypothesized impacts of several biotic and abiotic factors on ptarmigan dynamics and visualized them through a conceptual model. Then, they fitted state-space models to 15 years of ptarmigan monitoring data to: 1) quantify the effects of potential drivers of population dynamics (explanatory predictions) and 2) assess the ability of candidate models of increasing complexity to forecast next‐year population density (anticipatory predictions).

Understanding and predicting how climate change impacts Svalbard ptarmigan population dynamics

Iterative near-term forecasting is a promising approach to better understand and manage rapidly changing ecosystems such as the Arctic. Forecasts generated on a short-term time scale allow scientific hypotheses to be tested more frequently, speeding up scientific advancement, and are relevant to managers because the time scale can be influenced by...
