英文摘要: Tallgrass prairie habitats within North America have suffered severe fragmentation and habitat loss as land has been converted for agricultural purposes. Habitat loss and fragmentation can affect gene flow and the genetic structure of insect populations. Neoconocephalus bivocatus is a prairie obligate katydid found only in isolated prairie patches. We compared genetic diversity and population differentiation using AFLP markers in N. bivocatus and N. robustus , a grassland generalist that is not isolated to prairie fragments and occupies a more contiguous range. Similar levels of genetic diversity were present within populations of both species. While population genetic structure was found in both species, there was no relationship between assigned genotypes and sampling localities. This...
