Directional selection and repeatability in nest-site preferences of Semipalmated Plovers ( Charadrius semipalmatus )
Using marked individuals, we assessed directional selection and repeatability of nest-site characteristics of Semipalmated Plovers (Charadrius semipalmatus Bonaparte, 1825) on Akimiski Island, Nunavut, Canada, 2002–2005, to test the hypothesis that long- and short-term selection patterns were in the...
