Some of the best evidence for rapid evolutionary change comes from studies of archipelagos and oceanic islands. City parks are analogous systems as they create geographically isolated green spaces that differ in size, structure, and complexity. Very little, however, is known about whether city parks in single urban centres drive selection and result in the diversification of native species. Here, we provide evidence for the rapid genetic and morphological differentiation of a native lizard (Intellagama lesueurii) at four geographically close yet unconnected parks within one city. Year of establishment of each city park varied from 1855 (oldest) to 2001 (youngest) equating to a generation time range of 32 to three generations. Genetic divergence among city park populations was large despite the small pairwise geographic distances (< 5km) and found to be two to three times higher for microsatellites and three to 33 times higher for mtDNA relative to non-urban populations. Patterns of morphological differentiation were also found to be most extensive among the four city park populations. In contrast to non-urban populations, city park populations showed significant differentiation in relative body size, relative head and limb morphology and relative forelimb and hindlimb length. Crucially, we show that these patterns of differentiation are unlikely to have been caused by founder events and/or drift alone. Our results suggest that city park ‘archipelagos’ could represent theatres for rapid evolution that may, in time, favour adaptive diversification.

Usage Notes

Genotypes_13 markersGenotypes for four city parks (CP1, CP2 and CP3), three isolated non-urban (INU1, INU2 and INU3) and three connected non-urban populations (CNU1, CNU2 and CNU3) of eastern water dragons (Intellagama lesueurii). 13 microsatellite markers are included (taken from Frere et al., 2012) in the file, File is in the format accepted for GeneALEx.Morphology_EWD_7 popsMorphological measurements taken for four city park (CP1, CP2 and CP3) and three isolated non-urban (INU1, INU2 and INU3) populations of eastern water dragons (Intellagama lesueurii). File includes location, habitat type, sex, weight, jaw width, jaw length, upper forelimb length, lower forelimb length, upper hindlimb, lower hindlimb limb, tail girth and snout-ventral length. File is in a comma delimited excel spreadsheet.
