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.

`genzplyr` is an alternative syntax for `dplyr` that replaces boring old function names with GenZ slang. Your data wrangling is about to hit different.

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📢📢📢

A CONTROVERSIAL “APPEAL to Heaven” flag that has recently become associated with the “Stop the Steal” movement and Christian nationalism was flown above the Small Business Administration (SBA) agency last week in Washington, DC.
