von Büren et al. propose a novel, low-cost, and effective method to monitor above- and belowground microclimate in mountain environments year-round that withstands large animals and snow pressure and is suitable for remote areas.

It’s worrying to see arXiv stop accepting reviews and opinions. If other preprint servers like @biorxivpreprint.bsky.social do the same, science will lose an important space for open discussion.
As a community we need to find better ways to deal with the downsides of AI.

arXiv will no longer accept review articles and position papers unless they have been accepted at a journal or a conference and complete successful peer review.

This is due to being overwhelmed by a hundreds of AI generated papers a month.

Yet another open submission process killed by LLMs.

New paper from the MIREN network!

We tested how homogenisation (ecosystems becoming more alike through invasions) changes with scale.

Global = clear pattern
Local = not so simple
