Abstract
AbstractHumans change the environment according to their need, causing modifications and affecting the local biodiversity. This work applied a set of dominant markers to test if urban populations of Cyperus ligularis L. (Cyperaceae) present less genetic diversity compared to forest/non‐urban populations, and if these environmental differences (land use) influence gene flow and population structure. Six available populations of C. ligularis were collected in different types of environments in Recife (Brazil). Overall 15 primers of DNA Amplification Fingerprinting and Inter Simple Sequence Repeat were applied and analyzed by proper statistics. The results revealed moderate genetic diversity, significant pairwise gene flow (Nem), and low differentiation between populations (FST). Land use had no direct correlation with genetic diversity or structure, however, an insular population showed higher differentiation from the remaining. Urban environments may not influence gene flow among C. ligularis populations in such environments; therefore, the genetic diversity is homogeneous in the analyzed area.
