Are you an early-career biologist or ecologist who would benefit from an invited seminar? Would you like to come to UMaine next fall or spring to give a talk? Leave a brief comment with some info about what you do. I'm co-hosting our seminar series again, and am filling out our rosters.

We showed that large Arctic herbivores impact plant abundance by way of their effects on plant phenology: plants that emerge earlier under herbivory than under herbivore exclusion also had greater abundance later in the season, and vice versa. academic.oup.com/pnasnexus/ar...

Write your code knowing that you will deposit it with your paper. Trust me, this is good for you AND good for science. You'll be more careful if you know everyone else will eventually see your code and everyone else can learn from your methods. It's win-win!
