Code for: "Individual movement mechanisms explain landscape-scale variation in animal occurrence and density"

Individual movement mechanisms explain landscape-scale variation in animal occurrence and density General Information This repository contains the code and archived intermediate outputs used for the analyses presented in the manuscript, “Individual movement mechanisms explain landscape-scale variation in animal occurrence and density.” The workflow includes environmental raster preprocessing, fitting of individual integrated step-selection functions, and downstream prediction of SSF, RSF, SDM, and steady-state distribution (SSD) surfaces under current and future habitat scenarios. All analyses were originally run on a high-performance computing (HPC) system. Several stages of the workflow, particularly SSD-related transition-matrix construction and eigendecomposition, were computationally demanding and required very large shared-memory resources; the largest jobs were run with up to 1.9 TB RAM. Consequently, although the full code is provided, end-to-end reruns may require substantial computational resources as well as adaptation of file paths from the original HPC environment. To support reproducibility as fully as possible, we deposited intermediate files wherever file size constraints allowed, including selected model objects, processed raster layers, and derived outputs used in later stages of the analysis. Not all intermediate products could be archived because of storage limitations, but the included scripts document how omitted files were generated within the original workflow.
