Abstract
Osim promjena u staništu, koje uključuju njegovu redukciju i fragmentaciju, urbanizacija uzrokuje svjetlosno i zvučno zagađenje, kao i zagađenje zraka. Populacije se na zahvaćenom području često smanjuju i dijele u izolirane skupine. Posljedice urbanizacije mijenjaju i pokreću mehanizme adaptivne (prirodni odabir) i neadaptivne evolucije (genski drift i protok gena). Urbanizacija može smanjiti protok gena između populacija, a povećati učinak genskog drifta unutar populacija, što najčešće rezultira manjom genetskom raznolikošću unutar populacija, a većom genetskom diferenciranošću između populacija. Otkriveni su i slučajevi u kojima je protok gena olakšan, a učinak genskog drifta smanjen urbanizacijom, kao i slučajevi u kojima se njihova rata ne mijenja. Utjecaj urbanizacije na prirodan odabir opisan je na klasičnom primjeru evolucije donekle poznatom većini, na pojavi crnog tipa brezove grbice u industrijaliziranoj Engleskoj u 18.st., kao i na morfološkim promjenama koje se javljaju u urbanim populacijama guštera. Hoće li urbanizacija olakšati ili otežati preživljavanje neke vrste, ovisi o toj vrsti i promjenama koje urbanizacija donosi.
Abstract (english)
Except for the changes in the habitat, which include its fragmentation and reduction of its size, urbanization can cause light, air or sound pollution. Populations that live in the areas affected by urbanization often get separated and reduced in size. The changes in an ecosystem brought about by urbanization alter and initiate mechanisms of adaptive or unadaptive evolution. Urbanization can reduce the amount of gene flow among populations and increase the influence of gene drift within populations, which usually results in reduced genetic diversity and increased genetic differentiation. However, some cases report that urbanization facilitated gene flow and reduced influence of gene drift or that it had no effect on these mechanisms. The effect of urbanization on natural selection was described on the appereance of the black morphotype of Biston betularia in industrialized England of the 18th century and some morphological differences beetween urban and rural populations of lizards. Will urbanization help or disrupt the survival of a species depends on said species and on the changes it causes.
