| effect of cultivating croplands and grazing in arid grassland habitats on the conservation of melitaeine butterflies in a mountainous area in northern china. | in the study area (yanjiaping village, hebei province, china), grazing extensity varies at different locations, small and discontinuous croplands are imbedded in some arid grassland, which are habitats for the melitaeine butterflies, euphydryas aurinia and melitaea phoebe. these two species of butterflies coexist in this area, in which grazing and cultivation are the main disturbances. grazing and cultivation have a reciprocal effect on e. aurinia, rather than m. phoebe. we observed that e. auri ... | 2007 | 17393081 |
| genetic differentiation within metapopulations of euphydryas aurinia and melitaea phoebe in china. | we analyzed genetic differentiation within metapopulations of two species of checkerspot butterfly, euphydryas aurinia and melitaea phoebe, in china. to generate genetic information, we used a new molecular technique, dalp - direct amplified length polymorphism. amova results showed that most of the variation occurred among individuals within local populations of both e. aurinia and m. phoebe. however, while there was differentiation among local population in e. aurinia (p < 0.001), there was no ... | 2003 | 12670025 |
