The number of low-quality or fraudulent publications is rising to hundreds of thousands per year. It is time to reevaluate current publishing models and outline a global plan. Read the 'Reformation of science publishing: the Stockholm Declaration': royalsocietypublishing.org/doi/10.1098/... #RSOS 🧪

🌍 Reducing scientific travel cuts CO2 emissions but fragments the scientific networks.
With Tommaso Alberti on the @egu.eu Nonlinear Processes blog, we move from carbon accounting to carbon investment: travel less, but travel with purpose to keep science connected.

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

This is so cool!
Deciduous leaves may have evolved to be symmetrical and subtly lobed so they fall quicker and land near their parent tree, recycling their annually sequestered carbon.

🚨Paper alert!🚨

Just published in Mediterranean Botanty at
revistas.ucm.es/index.php/MB...

In this study we focused on the orchid diversity of the Principality of Asturias (NW Spain) and the drivers behind such diversity.
Orchids of the Principality of Asturias (Northwestern Spain) | Mediterranean Botany
In this study we present a review of the orchid family in the Principality of Asturias, Northwestern Spain. The study area comprises 10,000 km² for which we have compiled and curated up to 9197 records coming from several sources: fieldwork, herbaria, specialized publications, gray-literature, citizen science platforms, Global Biodiversity Information Facility (GBIF) and social media. The territory comprises 52 confirmed species and 13 hybrids, with other 16 possibly present species being discussed and still other 6 explicitly dismissed. Gymnadenia densiflora (Wahlenb.) A. Dietr. and all nothotaxa, except those in Serapias, represent novelties for the area. For each of the 52 species we provide a brief description of their habitat, altitudinal range and flowering period. Additionally, we present a statistical exploration of the main drivers of orchids’ ecology and distribution in the territory. Our review demonstrates how the Principality of Asturias, despite its marginal geographic position—away from major diversification centers—, and the scarcity of detailed floristic studies and, in particular, of those specifically focused on orchids, qualifies as a significantly orchid-rich region within the European context, even when judged by the demanding standards of the rich Iberian flora. The role of citizen science, particularly triggered by these cherished plants, has been and will continue to be crucial in perfecting our knowledge of Asturian orchids.

Today is my annual reminder that read_csv() is vectorized and you can just pass a vector of file paths and it will read and append the datasets.

No need to use map or for loops to read in multiple files.
