Tools

POPMAPS2 for population genomic mapping.

POPMAPS2 is a maintained successor to POPMAPS that estimates ancestry coefficients and ancestry probability surfaces from empirical genetic data across user-defined geospatial layers.

POPMAPS2

Spatial guidance from empirical ancestry estimates.

The tool is currently in public alpha: installable, tested, documented, and usable for validation work, while the public API is still being stabilized before the software manuscript and CRAN submission.

What it does

POPMAPS2 turns empirical ancestry estimates into raster surfaces that can show hard population boundaries, ancestry probability, ancestry coefficients, and areas of interpolation uncertainty.

Where it fits

It is designed as a downstream analysis tool. Population structure, species distribution modeling, EEMS/FEEMS, and resistance modeling run upstream, then their outputs can be supplied to POPMAPS2.

Why it matters

Spatially explicit summaries of intraspecific genetic variation can support seed sourcing, rare plant conservation, translocation planning, and other landscape-scale stewardship decisions.
