This paper was the most frustrating journey I've ever gone through...
Nevertheless, after nearly two years, the paper is finally published.

How to not be swamped by your microclimate data?
The rise of microclimate data may have opened Pandora’s box. Gone are the days of simple bioclimatic variables — now heads spin trying to summarize these timeseries.

I suspect a badger. Someone was repeatedly pulling off our EMS water potential logger (whole buried) while leaving TMS-4 standing right next to it... So now the EMS WP's got a fancy 2-sided + top cage that enables readout from a side. Let's see if that works.

In past, Daniel Kokotajlo made future projections on the development of AI that, over time, turned out as quite accurate. This is his vision of what might happen over the coming years. The projection are worrying, especially in the light of the recent disbalance of political order

Hi R users, do you have experience with R functions that use non-native languages (specifically C++ and Fortran) in parallel processing (foreach with %dopar%)? To me, this produces error: "NULL value passed as symbol address" and I can't figure the way out.
Thanks ❤️

Over the last few days, I've prepared an "initial distribution" of our target species for simulation models.
I used 1 m2 resolution topography, interpolated microclimatic variables, soil properties and snow from permanent cameras. We also gathered multispectral data with a helicopter.

Shrubification, increases of nutrient demanding species and decrease of habitats specialists. But also overall increase of community level species richness.

Working with red wine is always so satisfying. Bottling a batch feels almost like getting a paper published after all the waiting and reviewing. Anyway, these still have a long way ahead. 2024 was very special vintage with an extreme drought shortly before harvest. Tricky for natural winemakers.

Paper alert.
You might have heard about some trials of using hemi-parasitic plants to enhance biological restoration of grasslands. Yet it has been documented only from a few small experiment. However, a few years ago, Jakub Tesitel carried out an experiment to test this in different macroclimates.

I'm a regular R user, but I don't like R Studio for various reasons. I'd been using PyCharm instead for a long time, but since mid-2024, the R plugin is no longer maintained. I'm therefore searching for an alternative. Is anyone using something else than R Studio for R coding? #R #rstats #RStudio
