Postdoctoral Scholarship (2 years): Global Change Impacts on Northern Lakes The Department of Ecology and Environmental Science at Umeå University is seeking a motivated postdoctoral researcher to investigate the impacts of global change on northern lake ecosystems, with a f

Great postdoc opportunity! I escaped the first Trump administration by spending it in Umeå, here is a great chance for someone to do the same umustipendie.varbi.com/en/what:job/...

During the evaluation period (2023), submitted forecast models were most useful when in-lake conditions were most different to historical observations.
As conditions continue to move beyond what can be predicted from past observations, these forecasting methods will be more and more valuable! 📈

Skillful forecasts were generated using four model classes - process models, machine learning, empirical, and multi-model ensembles.

35-40% of models outperformed null models and the most successful models accounted for more sources of uncertainty (process, parameter, initial conditions, observational, drivers) with poor models often over-confident in their forecasts.

Using >100,000 near-term ecological forecasts, produced in real-time as part of the @ecoforecast.bsky.social NEON Forecasting Challenge, we looked at how different forecasting models performed for different lake variables and sites!

What can we learn from 100,000 freshwater forecasts? A synthesis from the NEON Ecological Forecasting Challenge Near-term, iterative ecological forecasts can be used to help understand and proactively manage ecosystems. To date, more forecasts have been developed for aquatic ecosystems than other ecosystems wo...

So exciting to see @freyaolsson.bsky.social's forecast synthesis paper officially published today!
