Wait and Snap: Snapping turtles prey on migratory fish at road-stream crossing culverts

This directory contains the files submitted to the journal for publication and open access.

This repository contains the data and R code necessary to reproduce the results presented in "Wait and snap:
Common snapping turtles prey on migratory fish at crossing culverts." by Alcott et al. submitted to Biology Letters for peer review.

The analyses are split into 3 parts corresponding with different analyses presented in the manuscript:
1. Fish positioning - data and analyses for fish cross-sectional position within culverts from underwater videography.
2. Stable isotopes - data and analyses for C13 stable isotope analyses of snapping turtle blood samples, river herring muscle tissue, and aquatic vegetation
3. Video Observations - data and analyses for quantifying the frequency of various behaviors that were reported from underwater videography
