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/...

The @wsl-dme.bsky.social lab members arrived at #TIBS2026 in Aarhus. We are excited to enjoy great talks, posters, workshops, discussions with colleagues and friends, and we look forward to contribute as well, with 7 oral and 5 poster contributions.
#Biogeography #Macroecology #Biodiversity

Great talk by @vboussange.bsky.social from @wsl-dme.bsky.social on "Multiscale species richness modelling". Victor developed a cool method to map species richness in a way that allows spatial scaling and to retrieve scale-relevant information.

Elena Plekhanova from @wsl-dme.bsky.social just gave a very interesting talk on how to use #AI in combination with #RemoteSensing to map global #biomes.

🗾The poster sessions at #TIBS2026 are a great opportunity to exchange results and ideas, and to meet new people. We enjoy the interaction and atmosphere. And we will leave with a rich set of new ideas and connections.🚀

Interesting talk by @nezimmermann.bsky.social from our DME lab today at #TIBS2026 on a new conceptual framework on #BiomeBiogeography. This concept is at the core of our #biome project, in which several lab members are involved.

Damiano Righetti from our DME lab just presented his cool research at #TIBS2026 on trophic species distribution modelling of tuna and its pray.

@wennading.bsky.social from the DME lab presented her great work at #TIBS2026 on the origin of mountain floras in response to biotic assembly, orogeny and climate change. If you are interested, her is the latest paper on the topic: www.science.org/doi/full/10....

Our DME member @dirknkarger.bsky.social gave a great talk on adapting land use to climate change and how this can mitigate global biodiversity decline.

Great talk at #TIBS2026 by @dirknkarger.bsky.social on how adapting land use to climate change may mitigate global biodiversity decline. Along these lines: check out our new paper on land use and climate change impacts on global biodiversity: onlinelibrary.wiley.com/doi/full/10....

Trump moves to shut down Boulder climate research lab NCAR, drawing rebukes from Colorado officials Federal lawmakers called the planned NCAR closure “deeply dangerous” and “blatantly retaliatory.” Gov. Jared Polis said: “If true, public safety is at risk and science…

The dismantling of NCAR should be the trending story on Bluesky, not the fucking Oscars leaving ABC for YouTube.

Exploring the tropical cloud forests of #Guacamayos. 🔎 Foggy, rain-soaked and mild temperatures: #cloudforests are some of the most species- and endemism-rich biomes on Earth. Despite covering only 0.4% of global land, they host 3,700 #species of birds, mammals, amphibians and tree ferns. 🌧️🌳🌿

🌧️ If your team members are patiently waiting for 1h in the rain in a tropical #cloudforest, chatting, playing, laughing and happily continue fieldwork with rain-sensitive instruments as soon as the rain stops & finish the day with a “high five”: Now you know, you have a fantastic team! 🫶

🌳 Towering trees (often >50 m), massive buttress roots and woody lianas are typical plant traits of tropical rainforests. 🌧

🚁🌳 We are collecting #biome data in #Ecuador using three types of #drones:

1️⃣ #LiDAR – to analyze vertical biomass distribution
2️⃣ Multispectral – to assess canopy leaf area
3️⃣ Photo – to capture leaf imagery

🌿Fieldwork in the #Yasuni National Park, #Ecuador.🦜
Our researchers are studying the structural and functional properties of #rainforests to better understand and define #biomes.🌳🔎

Deciphering tree drought responses across species: linking leaf water potentials with remote sensing greenness and photoprotection dynamics Monitoring forest drought stress requires indicators that capture tree water relations across species and scales. Remote sensing enables large-scale a…

New research reveals how to better monitor tree #drought #stress! We combined remote sensing data (greenness & photoprotection indicators) with leaf water potential measurements to track drought impacts across different tree species.

Global increase in the occurrence and impact of multiyear droughts Persistent multiyear drought (MYD) events pose a growing threat to nature and humans in a changing climate. We identified and inventoried global MYDs by detecting spatiotemporally contiguous climatic ...

Old news in new clothes www.science.org/doi/10.1126/... 😂

Go check out our event-based evaluation!
Beyond the global scale patterns of increasing multi-year droughts, there are over 10,000 identified events inventoried with explicit spatiotemporal coverage, from which one could easily extract events of their whatever interest across disciplines and uses.
