Tree of heaven (Ailanthus altissima) and South African ragwort (Senecio inaequidens) on the median strip of a Swiss highway.

The roadside vegetation was filmed using two cameras mounted on both sides of a car and the invasive plants were detected afterwards by AI. Further details: https://myvss.mobilityplatform.ch//vss/account/publication/2897/webviewer/

Image coordinates (car positions) of three surveys during the growing season 2021. Colors show the the number of image tiles in which Ailanthus was detected on the median strip (max. 15 tiles per image).

#AI #mapping of #invasive #alien #plants 👽🌱 across a national #road network 🛣️🇨🇭 using 58 M images. Presented this week at the Naturschutzkafi (Stiftung Landschaft & Kies). After 2021, a resurvey is planned for #monitoring this year. #Report + nationwide maps 👉 www.astra.admin.ch/dam/astra/de...

After a great time at #TIBS2026 in Aarhus - where I gave a talk on our genetically-informed dynamic SDM and after many exciting discussions - today was the perfect day to visit #ARoS with colleagues from Amsterdam.

The asynchronous rise of Northern Hemisphere alpine floras reveals general responses of biotic assembly to orogeny and climate change The asynchronous rise of Northern Hemisphere alpine floras was shaped by general responses to orogeny and climate change.

How have mountain building and climate change shaped alpine biodiversity over millions of years? Check out our new study in Science Advances! www.science.org/doi/10.1126/...

Arrival of the young Chinese windmill palm (Trachycarpus fortunei) at the Rhone Glacier (Image source, www.dorsa.cc).

🌴 #MigratingPalm is a young Chinese windmill palm transported from Ticino to the Rhone Glacier by the architecture collective dorsa just before a ban by the Swiss Federal Council. Inspiring 📽️ #clip and architects' perspective on #invasivespecies and #regulations.

View towards the east where first elements of the completely different flora of the Pannonian region occur.

Potentilla clusiana, an eastern alpine species that looks very similar to Potentilla nitida from the Dolomites.

Campanula alpina, also a species with an eastern alpine distribution.

Dianthus alpinus, another eastern alpine species.

How does the eastern distribution limit of #plants in the European #Alps look like? The #Schneeberg 🏔️ (2076 m) in #Austria near #Vienna is a great place to find out! The often isolated occurrences must have been better connected to the other populations in the past.

Pulsatilla vernalis, postfloral elongation

Pulsatilla vernalis

Pulsatilla vernalis

Ranunculus kuepferi

#Pulsatilla #vernalis, lady of the snows❄️, last weekend in the 🇨🇭Alps above treeline at c. 2250m🏔️. Early flowering in alpine spring with overwintering leaves next to Crocus albiflorus and #Ranunculus #kuepferi, and phenologically variable from early flowering to #postfloral #elongation.

80 years after #WW2 I stumbled across #Parietaria #pensylvanica in #Berlin. Thought to be escaped from botanical garden after bombings (or brought by 🇺🇸🪖?) it’s now well established on this #urbanbiodiversity #island 🏝️ but hasn't spread much further! #bioinvasions floraweb.de/php/artenhom...
