“…These results are consistent with the findings of Polic et al (2022) covering the entire Western Palaearctic and using a large number of sequence‐based markers. Their A. adippe samples from most of Europe formed a single genetic unit, differentiated only from the Iberian Peninsula.…”

“…In A. niobe , the situation in Central Europe was complex, with samples from the Alps linked to more westerly samples, and those from the Carpathians linked to the Balkans. Thus, both our results and those of Polic et al (2022) point to genetic interconnection of A. adippe across Central Europe, and to intermixing of A. niobe lineages, which probably formed during Pleistocene climate and habitat changes (e.g., Bartonova et al, 2020; Hammouti et al, 2010), in the area between the Carpathian Arc and the Balkans.…”

“…Their conservation status varies regionally; some are among the most rapidly declining butterflies in respective regions (Powell et al, 2007; Sanford, 2011; Swartz et al, 2015), while others are still safe (Mikitova et al, 2021; Zimmermann et al, 2009). Very recently, Polic et al (2022) used nuclear and mitochondrial DNA markers to study genetic patterns in three Palaearctic species, Argynnis aglaja (Linnaeus, 1758), A. niobe (Linnaeus, 1758) and A. adippe (Denis & Schiffermüller, 1775), in western parts of their ranges. They found weaker genetic structuring in the more generalist A. aglaja than in the more specialized A. adippe and A. niobe , and called for more detailed comparative studies of closely related species.…”

Perishing rich, expanding poor: Demography and population genetic patterns in two congeneric butterflies

et al. 2022

In human-altered landscapes, specialist butterflies typically form spatially restricted populations, genetically differentiated due to dispersal restrictions. Generalists, in contrast, display minimum differentiation but high genetic diversity. While local-level actions suffice to conserve specialists and landscape-level actions are necessary for generalists, minimum information exists regarding conservation of species with intermediate features. We targeted two congeneric butterflies, the recently re-expanding Argynnis adippe and the strongly declining A. niobe, co-occurring in the pastoral landscape of the Carpathian Mountains, Czech Republic. We integrated species distribution models, mark-recapture and microsatellite analysis to compare their habitat requirements, adult demography, dispersal and genetic patterns, and expanded the genetic analysis across the Carpathian Arc and beyond to delimit spatial conservation units. In two mountain valleys, both species formed interconnected populations numbering thousands of individuals. Mobility patterns suggested the populations' interconnection across the Czech Carpathians. Genetic diversity was extremely poor in the nonthreatened A. adippe and moderate in the declining A. niobe. No population differentiation was detected within the Czech Carpathians (~1500 km 2 ). Low genetic diversity and no differentiation was preserved in A. adippe across East Central Europe, whereas in A. niobe, populations from Serbia were differentiated from the Carpathian Arc + Alps. The high adult mobility linked to low differentiation probably reflects the distribution of larval resources, historically widespread but sparse and currently declining for A. niobe (grazing-disturbed grounds), while currently increasing for A. adippe (abandonment scrub, disturbed woodlands). Units as large as entire mountain systems define population boundaries, and hence conservation management units, for both species.

“…This may be particularly prevalent in species with large populations (Gillespie 2000) or in species that have experienced rapid range expansions (Petit and Excoffier 2009). Similar discordant results were detected in Speyeria aglaja (Lepidoptera: Nymphalidae) (Polic et al 2022), where distinct geographic lineages were detected with genome-wide SNPs but not with CO1 haplotypes. Polic et al (2022) suggested that gene flow or selective sweeps homogenised haplotype diversity and erased the spatial variation in the mitochondrial genome.…”

“…Intraspecific variation, especially if it is recently derived, often necessitates large numbers of independent and variable loci to accurately infer population and demographic histories and to resolve spatial genomic variation (Hey and Nielsen 2004;Carling and Brumfield 2007;Gompert et al 2014;Garrick et al 2015;Satler et al 2021). Recent technological advances provide access to single nucleotide polymorphisms (SNPs) spread throughout the genome (Baird et al 2008;Peterson et al 2012;McCormack et al 2013;Garrick et al 2015) and have been used successfully to resolve spatial genetic variation in many widespread, nonmodel organisms (e.g., Bagley et al 2017;Lumley et al 2020;MacDonald et al 2020;Cairns et al 2021;Polic et al 2022).…”

Genome-wide markers show continental structuring and mitonuclear discordance in the forest tent caterpillar (Malacosoma disstria Hübner) (Lepidoptera: Lasiocampidae)

The forest tent caterpillar, Malacosoma disstria Hübner (Lepidoptera: Lasiocampidae), is an irruptive forest pest found throughout North America. Widespread species such as M. disstria are exposed to historical and contemporary processes that are not uniform and can generate regionally distinct genomic variation. Previous analyses used a short mitochondrial fragment to infer broad-scale phylogeographic patterns in M. disstria, whereas nuclear markers have been previously applied only in a smaller geographic region. In this study, we quantified M. disstria population variation with genome-wide single nucleotide polymorphisms and cytochrome c oxidase from mitochondrial DNA. Using highly variable genome-wide markers, we resolved clear genomic differences among populations of M. disstria east of the Rocky Mountains that were not detected using mitochondrial variation alone. We also did not detect host-associated divergence in either our genomic or mitochondrial data. Our results highlight the utility of genome-wide markers to resolve intraspecific population structure within a widespread species and support the need for further biogeographic sampling of this forest insect pest.

The Fritillaria species ranked as a well-known traditional medicine in China and has become rare due to excessive harvesting. To find reasonable strategy for conservation and cultivation, identification of new ecological distribution of Fritillaria species together with prediction of those responses to climate change are necessary. In terms of current occurrence records and bioclimatic variables, the suitable habitats for Fritillaria delavayi, Fritillaria taipaiensis, and Fritillaria wabuensis were predicted. In comparison with Maxent and GARP, Biomod2 obtained the best AUC, KAPPA and TSS values of larger than 0.926 and was chosen to construct model. Temperature seasonality was indicated to put the greatest influence on Fritillaria taipaiensis and Fritillaria wabuensis, while isothermality was of most importance for Fritillaria delavayi. The current suitable areas for three Fritillaria species were distributed in south-west China, accounting for approximately 17.72%, 23.06% and 20.60% of China's total area, respectively. During 2021–2100 period, the suitable habitats of F. delavayi and F. wabuensis reached the maximum under SSP585 scenario, while that of F. taipaiensis reached the maximum under SSP126 scenario. The high niche overlap among three Fritillaria species showed correlation with the chemical composition (P ≤ 0.05), while no correlation was observed between niche overlap and DNA barcodes, indicating that spatial distribution had a major influence on chemical composition in the Fritillaria species. Finally, the acquisition of species-specific habitats would contribute to decrease in habitat competition, and future conservation and cultivation of Fritillaria species.
