Feel free to test drive the applications here:
elifelts.shinyapps.io/hatchR_demo/

We continue to build out additional applications. We just added a function to back calculate for spawn timing if embryos are observed hatching or emerging, as well as building out application to non-fish species. We currently have an example in the works with tailed frogs!

This software could be used in variety of applications ranging from planning field work or activities that might impact developing embryos (e.g. culvert replacement) to broad ecological studies.

hatchR allows users to easily create species- or population specific parameterizations to account for species not included in the base software or account for locally adapted populations.

hatchR works by using effective value models which allows users to account for variable development rates as daily temperatures vary. This circumvents traditional ATU models which are less accurate and precise than hatchR.

If you're interested, definitely read the manuscript but also visit the project website where we've provided substantial articles and case studies of how to operate the software from scratch.

Let’s be honest, that’s really a Harry Potter name

Looking for them!

This project is a collaborative effort among, @morgan-sparks.bsky.social, Eli Feltz, Allison Swartz, and Paul Frater.

A manuscript is forthcoming, and we appreciate any use and feedback folks have!

hatchR offers users access to established phenological models and the flexibility to incorporate custom parameterizations using external datasets. The package includes functions for model selection, phenology prediction, and visualization. Users include researchers, managers, and educators.
