Variations in risk-taking behaviour mediate matrix mortality's impact on biodiversity under fragmentation

The impact of fragmentation on biodiversity is driven by more than the spatial configuration of suitable habitat patches. Habitat is embedded in the surrounding anthropogenic land cover, known as the matrix, which plays a key role in species movement and connects the fragmented habitat. Whether the matrix is a barrier or a conduit to movement depends on the mortality of the moving individuals. However, individuals differ in their behavioural response to the risk posed by the matrix, with the willingness to enter the matrix depending on an individual's risk-taking behaviour. This individual-level behavioural variability is rarely considered but represents an additional mechanism shaping inter- and intraspecific competition as well as evolutionary behavioural responses. We used an individual-based model to scale up from individual foraging movements to the resulting community structure of a competitive small mammal community in differently fragmented landscapes. The model interactively co..., This repository provides the source code for the implementation of a dynamic and spatially explicit individual-based community model as well as the used input file to derive our results. The dataset was simulated using the individual-based community model (software downloadable from zenodo) and is provided as CSV files. Their visualization, as in the paper, is included as R-Scripts. , , # Variations in risk-taking behaviour mediate matrix mortality's impact on biodiversity under fragmentation

The data files have been generated with the individual-based small mammal community model.
The R scripts contain the processing of the data and generation of the paper’s main figures.

## Description of the data and file structure

The simulated data comes in 4 separate data files. Each simulation is initialized with a randomly generated seed to facilitate pseudo-randomness. The seed is unique for each simulation and therefore also functions as a unique ID. It is used to combine the several output files for each simulation.

##### 1) The *scenario* file stores the user-determined information for each simulation:
