conservation-genetics
Conservation genetics applies population genetics tools to understand genetic diversity, gene flow, and evolutionary potential in wild plant populations. For plant science, it is essential for identifying genetically distinct populations, detecting inbreeding depression, and prioritizing which populations or lineages to protect. This knowledge directly informs seed banking, reintroduction programs, and habitat management decisions for rare and endangered plant species.

A rare California lily growing across just 160 acres shows how minute differences in soil chemistry shape the genetic makeup of individual plants, even within a single, continuous population. The study reveals that fine-scale soil variation — not geographic distance — drives genetic diversity in extremely range-limited species.
The Tiburon mariposa lily has a total global range of only 160 hectares, yet fine-scale soil differences within that area predict genetic differences between individual plants.
Soil nickel and magnesium concentrations both showed significant associations with genetic distance, consistent with the known physiological challenges of serpentine soils.
Redundancy analysis and generalized dissimilarity modeling showed that total soil variation — not any single element — best explains genetic composition, implying holistic microhabitat selection is at work.
