The paper modifies transplant experiments to test habitat quality and quantity effects on species range limits, finding both factors decline at the range edge of Rhinanthus minor.

The study examines genetic diversity in an alpine plant during post-glacial range expansion and finds no decrease in genetic diversity, suggesting dispersal limitation is not a major factor in colonization dynamics.

The paper tests if urbanization disrupts latitudinal gradients in seed predation across 14,000 km of latitude, finding that gradients persist despite habitat modification.
