This year we’re, in addition to the regular business, using our fine-scale temperature maps to explore isolated cold spots in lower elevations to see if nival species survive there. Quite dangerous sites these cold spots…

Fieldwork in the Alps. 5th year on the same mountain. Even this calf wonders why are we still doing that.

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

Ah, and actually discovered one more cause of invalid external pointers in the way. terra rasters are non-exportable. stackoverflow.com/questions/76...

How to resolve "external pointer is not valid" with foreach() in R

I am working on a code that calculates park area within a given distance from each population pixel cell. Both datasets are 30m rasters, from which I'm extracting the class and xy coordinates (in m...

Oh, by comparing with your code, I found my bug. What a ridiculous one. 🤦‍♂️ Within the arguments of `runauto`, I was calling my own function defined outside the foreach. So it was that one that wasn't loaded on cores. Thanks a lot, man.

Thanks mate for coming back to this! Yes, I used .packages = ... argument in foreach.

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 ❤️

In the Czech Rep. nature conservation agencies started subsidising very mostly sheep grazing in the 90s to restore grazing on abandoned grassland reserves and the outcome was mostly a disaster. Spread of dogwood, increase of grasses on exp of herbs. 30 years later, still a common practice sadly.

Until tomorrow noon (CET) there is a last chance to contribute to a survey about the use of R packages in Ecology.

It takes a maximum of two minutes!

Great thanks to all who contributed. 💚

Hi there, my student is making a survey about the use of R packages in Ecology, could you please spend two mins on filling it 🥹 Very appreciated! And if you could spread it further (RT), that would be just awesome. ❤️

And if you are interested which packages are most popular among young ecologists and which among professors, just stay tuned. 😅
