| [evaluation of the state of the gene pool of natural populations of vertebrate animals inhabiting the fragmented landscape of moscow and moscow district (with special reference to brown frogs)]. | a system of urban ecological genetic monitoring has been developed for the first time in russia and in the world. as a model, two species of brown frogs, rana arvalis nilss. and r. temporaria l. (16 populations, seven isozyme loci) were used. an evaluation of the gene pool state in urban frog populations has shown that the diversity in the moscow frog populations was lower than that in natural populations (up to 80 and 50% in respectively r. anvalis and r. temporaria). mean heterozygosities per ... | 2006 | 16808243 |
