v1.0 Data and calibration models for capturing seasonal variations in faecal nutrient content from tundra herbivores using near infrared reflectance spectroscopy

This repository contains R scripts, resources and data used to calibrate and predict faecal nutrient content from Icelandic tundra herbivores using near-infrared spectroscopy (NIRS), and to analyse seasonal variations in faecal nutrient content from tundra herbivores. For questions about the dataset or models, please contact: Mathilde Defourneaux – [e-mail] Detailed information about the methodology can be found in Defourneaux et al. 2025 (in press) Reference: Defourneaux, M., Barbero-Palacios, L., Schoelynck, J., Boulanger-Lapointe, N., Speed, J.D.M., Barrio, I.C., 2025.
