Temperature-driven density gradients of two congeneric felids reveal contrasting responses to climate change at a range margin

Climate change causes divergent range shifts in cold versus warm-tolerant species, potentially reshuffling biotic interactions at range margins. Yet, outside of coarse distributional metrics, little information exists regarding the ecology of species along range peripheries. Here, we use camera traps and spatially-explicit capture-recapture (secr) modeling to examine how climatic gradients influence current and future patterns of density, abundance, and density overlap between two congeneric felids - cold-adapted Canada lynx (Lynx canadensis) and warm-adapted bobcats (Lynx rufus) - at a range margin in Washington, United States. Temperature drove density patterns along the range margin, with lynx densities declining and bobcat densities increasing as a function of temperature. Future abundances, obtained via projection of current-day models onto future climate scenarios, declined for lynx but were stable for bobcats, with both species experiencing upward elevational shifts.

## Description of the data and file structure

Temperature-Driven Density Gradients of Two Congeneric Felids Reveal Contrasting Responses to Climate Change at a Range Margin

This dataset contains .csv files, .tif files, and the associated R code that implements the .csv and .tif files to conduct spatially explicit capture recapture analyses for Canada lynx and bobcats.

Two of the .csv files (i.e., \"Bobcat_CH_Summer_2023_5_Day\" & \"Lynx_CH_Summer_2023_5_Day\") represent the capture histories of individual bobcats and lynx. These files include information regarding which camera trap station (i.e., \"Detector\") individuals were detected at, as well as when these individuals were detected (i.e., \"Occasion\").

The third .csv file (i.e., \"Detectors_Condensed_5_Day_Occ_Dryad\") contains information on th...,
