Intraspecific Functional Trait Responses to Experimental Warming Vary With Precipitation and Growth Form We assessed the intraspecific functional trait response of 17 alpine plant species to experimental warming across a precipitation gradient. Warming consistently increased plant height. In contrast, t...

How do alpine plants respond to warming?Intraspecific trait shifts depend on precipitation and growth form, with stronger responses in forbs than graminoids.

Congrats Kryštof, way to go! Happy to hear that you had a good experience with the defense :)

15 open PhD positions in our @terra-cluster.org @unituebingen.bsky.social (with @unihohenheim.bsky.social and @sgn.one). All on biosphere-geosphere interactions, from eco-evo to soil science, hydrology, geology and paleontology. Check FUN01 and FUN04 if you want to work with us (detailed ads follow)

The job Cooperating in the field of periglacial vegetation development with other Helmholtz centres, we offer a PhD position (f/m/x) to survey and analyse the development of vegetation and associated microbiomes in glacier forelands of the Alps. Your tasks • Collection of vegetation data in glacier forelands and surroundings • Collection of soil and root samples • Analyses of soil and root associated microbiomes through meta-barcoding • Analysis of the link between vegetation and microbiome development as a function of (successional) time • Scientific publications We offer A lot of things, but space does not permit. Please see the link for details. Your profile • Degree (Master, Diploma) in biology, ecology, geoecology or comparable courses of study • Experience in the field of vegetation methods (vegetation surveys) • Field work experience in soil and root sampling for microbiome analysis • Lab skills to analyse the microbiome like DNA extraction, PCR, and sequencing • Knowledge of the Northern Alpine flora • Experience in high mountains and the ability to hike several hours a day and 1000 metres in altitude with luggage and equipment • Orientation skills in the mountains • Ability to work independently and solve unexpected problems • Statistical skills (preferably in R), knowledge of data storage (databases) desirable • Very good knowledge of English (communication in the working group, reading technical literature, writing technical articles)

Interested in pursuing your PhD in Alpine Ecology? How do ecosystems emerge after glacial retreat? Come with us @ufz.de as a PhD researcher on the development of vegetation and microbiome in glacier forelands.

Earth's largest land animals are limited by salt.

Sodium availability constrains the density and distribution of elephants, giraffes and rhinos across Africa, and offers a new explanation for the so-called 'missing megaherbivores'.

The Uni Basel Ecology group sitting around a table in front of a projected slide, discussing how to identify AI-written text.

An AI-created visualisation of a dataset of bird counts in Sweden. The chart is very confusing and messy and has little to do with the underlying data, so would not recommend using AI blindly for visualising even medium-complex data :)

A common kingfisher (Alcedo atthis) on a branch above a lake in evening light, photographed through a spotting scope.

At our science #retreat yesterday we discussed applications & pitfalls of various #AI tools for our work, from writing to species ID'ing. A great opportunity to learn from each other, develop a common understanding, & connect across the team!
And to go out for some birdwatching during lunch break 🦆

Genuine talent doesn't emerge from a vacuum.

It results from a massive effort: try, fail, learn, and repeat until failure becomes success, whatever that means.

Running the loop for long enough might get you there, hopefully.

Offloading the grind to a machine surely won't.

RIP #JaneGoodall - one of the modern pioneers of profound interconnections between people, animals and ecosystems. Her life was lived through science, compassion and tireless advocacy for the multiple values of nature - leaving a legacy that will endure for people and planet.

We had a great time at #Jungfraujoch during our yearly team outing! Got a fascinating tour of the meteorological & research station (est. 1931), and really enjoyed the trip with the iconic railway (construction finished already in 1912!). We'll have to come back for a better view, though 😉🏔️❄️🧪🚞

Debating the aesthetics of #wind & #solar is a luxury. The real crisis is climate change—threatening billions with deadly heat & catastrophic ecosystem breakdowns ♨️🥵🔥 Green #energy is a necessity🍃 Challenges exist (noise, land use) but are manageable - biggest risk is inaction #dkpol #climatechange

Took a small break from talks & discussions at #IMC25 this morning to explore the #alpine surroundings above #Innsbruck. Great views, and happy to see quite some flowers still (or again?) around late in the season 🌸🪻🌿🏔😊

Incredible ice loss measured again at #Konkordiaplatz on the #Aletsch #Glacier, home to the thickest ice in the #Alps (still about 800 m!). Yesterday’s survey revealed another –4.6 m of ice gone in just one year. :(
