Does urbanization lead to parallel demographic shifts across the world in a cosmopolitan plant?

A. E. Caizergues, J. S. Santangelo, R. W. Ness, F. Angeoletto, D. N. Anstett, J. Anstett, F. Baena-Diaz, E. J. Carlen, J. A. Chaves, M. S. Comerford, K. Dyson, M. Falahati-Anbaran, M. D. E. Fellowes, K. A. Hodgins, G. R. Hood, , M. T. J. Johnson

This study examines the demographic effects of urbanization on white clover populations globally, finding increased gene flow and no reduction in genetic diversity in urban areas.

Predicting the strength of urban-rural clines in a Mendelian polymorphism along a latitudinal gradient

J. S. Santangelo, K. A. Thompson, B. Cohan, J. Syed, R. W. Ness, M. T. J. Johnson

The paper examines urban-rural clines in a Mendelian trait of white clover across cities, finding that winter conditions influence HCN frequency changes, with snow reducing selection pressure in colder cities.

Modern spandrels: The roles of genetic drift, gene flow and natural selection in the formation of parallel clines

J. S. Santangelo, M. T. J. Johnson, R. W. Ness

The paper uses simulations to show that genetic drift can create phenotypic clines in urban environments, mimicking adaptive changes when traits have non-additive genetic bases.

Induced defenses alter the strength and direction of natural selection on reproductive traits in common milkweed

K. A. Thompson, K. A. Cory, M. T. J. Johnson

This study shows induced defenses in common milkweed change the strength and direction of natural selection on reproductive traits, independent of foliar damage.
