| can low densities of carnivores result in genetic depletion? an investigation within french polecat populations. | carnivores as top predators are commonly found in relatively low densities even in optimal habitats. despite a lack of empirical studies, it could be suspected that long-term low density could result in genetic depletion. the genetic structure of european polecat mustela putorius natural populations was investigated by allozyme electrophoresis in five distinct areas. density estimates significantly differed among sites from 0.17 to 0.83 individuals/km2 with an average of 0.56 individuals per km2 ... | 2006 | 16706919 |
