The Tielbörger lab at @unituebingen.bsky.social is offering TWO PHD POSITIONS in rangeland ecology, as part of the sage-centre.org. It is about tipping points in Middle Eastern rangelands. A large interdisciplinary project with unique long-term experiments!

We are still looking for a PhD student to work on feedbacks between plant invasion and riverbank erosion, embedded in the @terra-cluster.org. In collaboration with geoscientists and modellers; cool combination of field work & experiments. Position is in the Tielbörger lab, in collab with our group.

"Sun dogs" (#parhelia) this morning on my way to work. Almost tripled sun (22° halo) caused by refraction of sun light by ice crystals in the air. Very strange, and weirdly blinding.

Es war die guuuude alde Zeeit! Und natürlich Hessi James!

Only 1 week left to apply for your #dreamPhD position on #GeneticDiversity of #Proteas! Amazing combination of field work, wet and dry lab, amazing collaborators in #FynFUN and @terra-cluster.org, and definitely one of the most beautiful study systems and common gardens in the world! Please RT.

Please RT: we are looking for a PhD student to work on macrogenetics and quantitative genetics of South African proteas. Amazing collaborative project with @plantecology.bsky.social @debbiemleigh.bsky.social & others, embedded in @terra-cluster.org. Dream project if you love molecular biodiversity!

Time to publish responsibly: DAFNEE, a database of academia-friendly journals in ecology and evolutionary biology Abstract. The current economics of scientific publishing reveal a profound imbalance: academia pays prices far exceeding the actual costs of publication. R

Das ist wirklich total gaga

An exciting PhD in plant invasion ecology, with lots of interdisciplinary collaboration, and a cool combination of field work & experiments? Check out this offer in the Tielbörger lab @unituebingen.bsky.social, with involvement of our group and several others, embedded in the @terra-cluster.org.

An exciting PhD project in conservation genetics? Check out the one below @uni-freiburg.de that will survey genetic diversity across species to understand the big picture - very important! In collaboration with many others (incl. our group) and the @bexplo.bsky.social community.

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)

I am interested in working with an artist on a graphic novel on soil and/ or global environmental change. The lab would have money to fund this.

Do you know of any graphic artists that would be interested?

What a fabulous #BES2025 conference this has been! How friendly and modern and fun! So much great science, amazing keynote by Sandra Diaz, great party, good food. And Edinburgh is a very cool city.

The commitments in the SAFE Labs Handbook.

A new community-driven lab handbook for reducing conflict and creating more positive and equitable work environments gets strong support from a survey of 200 researchers.

What an amazing opening keynote by Sandra Diaz at #BES2025 - from the global plant phenospace to human drivers and use, to our relationship with plant species.

Wow

75 people?!

course schedule as a table. Available at the link in the post.

I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students.

I will record lectures & all will be found at this link: github.com/rmcelreath/s...

New study by @bmwildermuth.bsky.social et al. in @natecoevo.nature.com

They asked whether arthropod biomass declines due to species loss per se, or which species are lost, or because of shrinking abundances of persisting species. 🪲🕷️🐝🦗

Out now! 🌿🎙️ In this month's episode of #InsideBiodiversity, Prof Marten Scheffer explains critical transitions and tipping points.

Together with iDiv's Dr Volker Hahn, he explores whether local tipping points can be scaled up to a 🌍 biospheric planetary boundary.

How to measure seed longevity in storage when comparing accessions or species? We looked in detail at the most widely used measure (p50) and found out that it is... suboptimal at best. We highlight alternatives. @gfoesoc.bsky.social @unimarburg.bsky.social

Arthropod species loss underpins biomass declines - Nature Ecology & Evolution Insects are declining in many regions. Here the authors show that arthropod biomass losses in Jena Experiment and Biodiversity Exploratories time series are driven more by species loss than by species...

What are the mechanisms behind terrestrial arthropod declines? @bmwildermuth.bsky.social and colleagues have some answers
