Long-term human land-use change throughout Southeast Asia reshapes the distribution of suitable habitat for a human-commensal bird species

Aim: Human activity has reshaped ecological communities for thousands of years. While these activities have typically led to habitat loss, some species have successfully exploited human environments. However, the effects of long-term human land-use on the distributions of such species are poorly understood. Here, we investigated how land-use change over the last 12,000 years has altered the distribution of suitable habitat for a widespread human-commensal bird species, the Pacific swallow (Hirundo tahitica). 
Location: Southeast Asia, Melanesia
Methods: We built species distribution models using community science records and evaluated approaches to controlling for spatial biases that arise from using unstructured survey data to model species associated with anthropogenic environments. We then assessed the distribution of suitable habitat for Pacific swallows under three alternative scenarios of land-use change that incorporated only climate variables, only human land-use variables,..., , , # Data from: Long-term human land-use change throughout Southeast Asia reshapes the distribution of suitable habitat for a human-commensal bird species

The presence/background datasets for each of the pseudo-absence methods used are included in this repository. Background points were generated using inverse distance weighting, random sampling, and zero-filling using the same filtered presence points. Environmental conditions were used to assess the distribution of suitable habitat, with the present-day conditions included as well.

## Description of the data and file structure
