Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 August 2030.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2030.

Abstract

This project will study the origins of aposematism as a defensive strategy linking toxic chemicals and warning signals. This complex trait is thought to have started in cryptic ancestors and evolved through intermediate stages toward an optimal defense strategy. Aposematic poison frogs (Dendrobatidae) are well-studied, and these amphibians display an array of colors (reds, blues, and yellows) that advertise their…
