Thanks to everyone involved and special thanks to @gonzalezgvictor.bsky.social to bring color to my presentation with his wonderful illustrations.

Today I presented at #iDivconference2025 on using the microclimf R-package to model within-forest climate conditions for vegetation science 🌳🌡️. The model is performing really well so far—exciting insights ahead!
Full results coming soon at #BES2025 this December 🌱

Last week I could attend the II SEBOT conference in Seville, where I presented my research focused on the natural communities of Scots pine (Pinus sylvestris) in the Iberian Peninsula.

🚨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.

When we think of habitats, we often imagine vast landscapes, like forests or grasslands. But for fungal endophytes 🍄, the habitat can be as small as a single leaf 🍃.

Even intra-individual leaf trait variation within a tree helps shape and support a more diverse fungal community. 🌱🧬

🚨 Stat tips 🚨

Are you aware of the regression to the mean #RTM effect?

This artefact is often overlooked in #ecology & especially in biodiversity resurveys 🌳🍄🦔🦅🦎🦋🐝🐞 It basically shows up each time you investigate changes between 2 time events: t2 vs t1

Let me unfold it for you 🧵
