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
high similarity between flanking regions of different microsatellites detected within each of two species of lepidoptera: parnassius apollo and euphydryas aurinia.	microsatellite flanking regions have been compared in two butterfly species. several microsatellite flanking regions showed high similarity to one another among different microsatellites within a same species, but very few similarities were found between species. this can be the consequence of either duplication/multiplication events involving large regions containing microsatellites or of microsatellites imbedded in minisatellite regions. the multiplication of microsatellites might also be link ...	2004	15140111
caterpillars of euphydryas aurinia (lepidoptera: nymphalidae) feeding on succisa pratensis leaves induce large foliar emissions of methanol.	a major new discovery made in the last decade is that plants commonly emit large amounts and varieties of volatiles after damage inflicted by herbivores, and not merely from the site of injury. however, analytical methods for measuring herbivore-induced volatiles do not usually monitor the whole range of these compounds and are complicated by the transient nature of their formation and by their chemical instability. here we present the results of using a fast and highly sensitive proton transfer ...	2005	16101921
[egg cluster pattern of two coexisting melitaeine butterfly species and oviposition site selection of their adult females].	in this study, the oviposition sites of euphydryas aurinia and meiltaea phoebe adult females in the same habitat network were investigated, aimed to identify the factors affecting the patch quality. the results showed that the egg-laying females of both melitaeine butterfly species preferred to oviposit in the open areas with large-sized host plants and surrounded by short vegetations, especially on warm and sunny slopes. for e. aurinia, most of its egg clusters were concentrated within the area ...	2006	17044502
lonicera implexa leaves bearing naturally laid eggs of the specialist herbivore euphydryas aurinia have dramatically greater concentrations of iridoid glycosides than other leaves.	we tested in the field the hypothesis that the specialist butterfly euphydryas aurinia (lepidoptera: nymphalidae, melitaeinae) lays eggs on leaves of lonicera implexa (caprifoliaceae) plants with greater iridoid concentrations. we conducted our investigations in a mediterranean site by analyzing leaves with and without naturally laid egg clusters. there were no significant differences in iridoid glycoside concentrations between leaves from plants that did not receive eggs and the unused leaves f ...	2006	16902827
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
minimum viable metapopulation size, extinction debt, and the conservation of a declining species.	a key question facing conservation biologists is whether declines in species' distributions are keeping pace with landscape change, or whether current distributions overestimate probabilities of future persistence. we use metapopulations of the marsh fritillary butterfly euphydryas aurinia in the united kingdom as a model system to test for extinction debt in a declining species. we derive parameters for a metapopulation model (incidence function model, ifm) using information from a 625-km2 land ...	2007	17708221
changing demography and dispersal behaviour: ecological adaptations in an alpine butterfly.	high mountain ecosystems are extreme habitats for all organisms and therefore demand specific adaptations. in this context, we studied the ecology of the butterfly euphydryas aurinia debilis in the high tauern (austria) and compared the obtained data against the ecology of the species in lower elevation habitats. we performed mark-release-recapture studies over the entire flight periods (end of june to end of july) in 2007 and 2008 to analyse the fundamental ecological parameters of a population ...	2010	20652595
host-associated genomic differentiation in congeneric butterflies: now you see it, now you do not.	ecotypic variation among populations may become associated with widespread genomic differentiation, but theory predicts that this should happen only under particular conditions of gene flow, selection and population size. in closely related species, we might expect the strength of host-associated genomic differentiation (had) to be correlated with the degree of phenotypic differentiation in host-adaptive traits. using microsatellite and amplified fragment length polymorphism (aflp) markers, and ...	2013	23927539
three in one--multiple faunal elements within an endangered european butterfly species.	ice ages within europe forced many species to retreat to refugia, of which three major biogeographic basic types can be distinguished: "mediterranean", "continental" and "alpine / arctic" species. however, this classification often fails to explain the complex phylogeography of european species with a wide range of latitudinal and altitudinal distribution. hence, we tested for the possibility that all three mentioned faunal elements are represented within one species. our data was obtained by sc ...	2015	26566029
repetitive flanking sequences challenge microsatellite marker development: a case study in the lepidopteran melanargia galathea.	microsatellite dna families (mdf) are stretches of dna that share similar or identical sequences beside nuclear simple-sequence repeat (nssr) motifs, potentially causing problems during nssr marker development. primers positioned within mdfs can bind several times within the genome and might result in multiple banding patterns. it is therefore common practice to exclude mdf loci in the course of marker development. here, we propose an approach to deal with multiple primer-binding sites by purpos ...	2016	27273885
