摘要: : The population of Rhinoceros unicornis in the Chitwan Valley, Nepal, was reduced to an estimated effective size (Ne 21–28 individuals (60–80 total animals) 1962. Protein electrophoresis shows that heterozygosity remains very high this (Ho= 9.9%) despite its near extinction. We attribute large Ne's prior bottleneck, recent occurrence and long generation time. These results illustrate importance considering historical demography life history parameters when evaluating possible genetic effects bottlenecks wild populations. They also offer support arguments erosion diversity attributed may be overemphasized. Resumen: La poblacion de en el Valle Nepal; fue reducida a un tamanno efectiva estimada (Ne) individuos animales) electroforesis proteinas muestra que la heterosidad permanence muy alta esta pesar estar punto extinguirse. Atribuimos al gran anterior cuello botella poblacion, reciente ocurrencia del y a1 largo tiempo generacional. Estos resultados ilustran importancia considerar historial demografico los parametros boilogicos cuando se esten evaluando posibles efectos las poblaciones silvestres. Los tambien apoyan recientes discusiones diversidad genetica, debido cuellos botella, puede siendo sobre-enfatizada.
