Super important paper showing the startlingly low number of active plant taxonomists in the world, and in particular in some of the most biodiverse regions! Definitely a study I'm adding to my reference manager!

Sonoran Desert landscape looking west across Avra Valley from Tucson Mountain Park. In the foreground, a desert trail winds through cholla cacti, saguaros, ocotillo, and native shrubs. The valley stretches to distant mountain ranges on the horizon under a dramatic sky of blue patches and white cumulus clouds with rays of light breaking through.

General laws of biodiversity: Climatic niches predict plant range size and ecological dominance globally | PNAS A longstanding question in ecology asks whether or not species that achieve large geographic ranges also have large climatic niche breadths. Using ...

in "General laws of biodiversity: Climatic niches predict plant range size and ecological dominance globally", we provide key insights into species’ vulnerability to environmental change and the processes that structure biodiversity at global scales.

We are glad to share our recent article pulbished in @pnas.org, where we we demonstrate that plant species that occupy larger geographic ranges tend to have broader climatic niches and are more likely to achieve high local abundances.

@tanyadoesscience.bsky.social just told me about this today. Just in time for my lecture on #tidyverse this week. But I'm going to need a #xennial version as well.

USF told us how much they think we’re worth: an extra $15-22 per paycheck. That’s insulting, unacceptable, and after inflation amounts to a pay DECREASE that keeps Masters GAs BELOW the federal poverty line. We deserve better, and we’ll keep fighting for it📢📢📢

USF’s proposed raise of 2% can’t buy much: here’s a few things this money CAN’T buy. If you think we’re worth more than half a tank of gas every two weeks, drop something else you can’t buy with 2% in the comments⬇️⬇️⬇️

BREAKING: Graduate Assistants at USF deserve more, and people are noticing. Check out this article about our fight for fair wages in the @tampabaytimes.bsky.social this morning!🗞️

Awesome! This will be super useful!

One in six species on Earth experienced extraordinarily high temperatures across more than 25% of their range in 2024--the hottest year on record. For most, this was the second year of extreme heat, likely compounding risks. In PNAS: www.pnas.org/doi/10.1073/...

Fair. And since these are McFarlane figures, they're really more statues than action figures anyway, so not much point in opening them.

New in @pnas.org we assess future #climate exposure for 32,089 species of #trees🌳
🔹69% face unprecedented climates in ≥10% of range
🔹In taiga & Amazonia >50% of local tree diversity exposed
🔹 31% of species retain >90% of range in stable climates -> important climate refugia♨️
