Meet the Threshold team in Umeå!
Usually committed to uncovering climate-driven tipping points in mountain ecosystems...
...but currently taking a quick break to enjoy some beautiful sake and non-work-related chat
Note that these data were collected by David Eldridge in 2001, which just goes to show, it's never too late to publish that old dataset!!!

We also found that it was mostly trees and shrubs that suppressed biocrusts, not groundcover plants.
I thought groundcover plants would have the strongest suppressive effect, as they're closer to the ground and can block more sun. But leaf litter is probably more important here.

Longer answer: biocrusts tend to be more extensive and species-rich in places with high-condition vegetation.
What's happening is probably a common response to livestock, which simultaneously reduce biocrust cover (trampling) and encourage exotic annual vegetation
(2/4)
In most places, more vegetation cover = less biocrust, which is easily shaded or buried under leaf litter.
But what about vegetation condition?
Do biocrusts do better in high-condition vegetation with lots of native perennials?
Our new paper says: yes

Okey dokey! People who identify as
#PlantScientists and/or love #PlantScience,
If you'd like to share your name and Mastodon identity with others, and be discoverable, please complete this google form: https://forms.gle/MTqR9tZfkDS53Rdo8
I consider the term "plant science" to be VERY broad! Fossils, paleobotany, synbio, botany, ecophysiology, microbes that hang out with plants, etc. We're inclusive ❤️
Results will display here: https://docs.google.com/spreadsheets/d/1eimFqYMERb5uR4Sh5QOu1g4ZWosngj5nHQEpAeix55I/edit?usp=sharing
Hopefully that works - if not please let me know!
An open list for plant scientists (and those who interact with the plant science community) who are present on Mastodon - maintained by @[email protected] (Mary Williams) and adapted from the Chemistry Community list curated by @[email protected] Note: Information included on this form will be publicly available through a google form - it's purpose is to help plant scientists (and those that interact with them) to more readily find each other.

A little #introduction toot!
I'm Max, I just started a postdoc at SLU in Umeå, Sweden. I'm really interested in: #ecology, #globalchange, #terrestrial #macroecology, #climatechange, #functionaltraits, #carboncycle.
My PhD was on #rangeshifts in #biocrust species in Australian #drylands and Norwegian #tundra. Currently working on a global study, #projectthreshold, to uncover nutrient cycling tipping points in mountain ecosystems.
Also I use they/them pronouns in english 🙂
