One in six species on Earth experienced extraordinarily high temperatures across more than 25% of their range in 2024--the hottest year on record. For most, this was the second year of extreme heat, likely compounding risks. In PNAS: www.pnas.org/doi/10.1073/...

Nerdland – CanopyChange
Op Nerdland festival voerden we een experiment uit tezamen met meer dan 400 festivalbezoekers! We stelden onszelf de vraag of zomereiken een verschillend aantal huidmondjes op hun bladeren hebben afhankelijk van het microklimaat dat ze ervaren. Een zomereik die op een parking staat, ervaart andere temperaturen dan een zomereik die in een bosje op een eiland staat. Zomereiken die op de parking van het provinciaal domein Puyenbroeck staan zullen in de zomermaanden warmere temperaturen ervaren omdat ze in volle zon staan omgeven door asfalt. Zomereiken in een bosje op een eiland van het provinciaal domein zijn daarentegen omringd door andere bomen, staan in de schaduw en zijn omgeven door water. Wanneer bomen droogtestress ervaren sluiten ze hun huidmondjes, de poriën in het blad waarmee ze CO2 opnemen, maar ook waterdamp verliezen. Zo houden ze meer water vast en kunnen ze vermijden dat blaadjes verwelken. De hypothese luidde daarom dat zomereiken op de parking sneller hitte- en droogtestress ervaren vergeleken met zomereiken op het festivaleiland en bijgevolg verwachten we dat bomen op de parking meer huidmondjes hebben om hun waterverlies efficiënter te regelen.

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.
