An analysis of 21 years of monitoring across Europe now demonstrates that climate warming is increasingly displacing species from mountaintops, especially those that are close to their lower range margins. Learn more this week in Science: scim.ag/4zYxuUS
Alpine vegetation, such as this grassland in the Bernese Alps, Switzerland, is changing under the impact of decades of warming. Species richness has increased in many locations owing to plants migrating upward. However, analysis of 21 years of monitoring across Europe now demonstrates that climate warming is also increasingly displacing species from mountaintops, especially those that are close to their lower range margins.

Yesterday we shared the paper. Today I want to share the story behind it. We thought it was all about climate change. Then the models failed. That failure eventually led us to disturbances, and to a very different view of Europe’s flora. Read it @ communities.springernature.com/posts/europe...

The fallacy of single imputation for #traits databases: Use multiple imputation instead @methodsinecoevol.bsky.social #ecopubs doi.org/10.1111/2041...

    The past few years have seen the publication of many new trait databases. A common problem with large databases is a lack of completeness, or inversely, the high prevalence of missing values.
    Biologists have developed several methods to impute (fill in) missing values. This allows ordinary statistical procedures to be used in analyses and the use of only complete cases, with a concomitant loss of power and accuracy, can be avoided.
    Often, biologists use simulation to test new methods by deleting values from a dataset and recording how well the imputed values match the known, removed values.
    Here we argue that this is a poor measure of the strength of an imputation method. We also describe the importance and logic of the statistical procedure of multiple imputation, which requires that the imputations need not be precise or accurate estimates of the missing data.
