“…Petit et al, 2001) requires also knowledge on their dispersal abilities. Improved analytical tools allow to study the dispersal of various model organisms (Petit et al, 2001;Ulrich & Zalewski, 2007) in different landscapes (Van Dyck & Baguette, 2005;Bonte et al, 2006;Sander et al, 2006;Campagne et al, 2009). Despite the advances, the questions most frequently asked by conservationists remain simple: what is the probability for an average individual to cross a given distance, and what is the range of maximum distances that individuals from a given population may realistically cover.…”

Abstract. Knowledge of the dispersal ability of endangered species is crucial for developing effective, evidence-based conservation policies. Due to their limited dispersal abilities and specific habitat requirements, insects are among the animals most threatened by habitat fragmentation. We studied three populations of the highly endangered species of ground beetle, Carabus hungaricus, at three sites in Central Europe (Hungary and Czech Republic) using mark-release-recapture (MRR). The total catch of 574 pitfall traps set at the three sites was 6255 individuals. Depending on the site, the percentage recaptured was 13-32%. average and maximum distance moved by individuals of both sexes at each of the sites ranged between 47-132 and 207-1104 m, respectively. The probability of the movements following an inverse power function (IPF) for the two sexes did not differ, but did differ among sites. Probability of dispersing for distances >100 m differed by an order of magnitude between sites, most likely because of differences in how the samples were collected. Despite the fact that individual beetles are able to move over distances in the order of kilometres, the high fragmentation of their habitats is likely to prevent them from colonizing most uninhabited habitat patches. Therefore, the conservation of this threatened ground beetle could be improved by adopting and implementing a policy of assisted dispersal. our results from three study sites also provide an interesting illustration of the variability in the estimates of the probability of dispersal obtained using MRR.* Deceased.

“…Using GBS data of the ground beetle C. arcensis from island and mainland sites in Denmark and Sweden we found an overall significant isolation by distance (partial Mantel test of F ST and geographic distance, when controlling for transoceanic distance, P = 0.0461, r = 0.582), but a lack of any significant impact of an ocean water barrier on isolation (partial Mantel test of F ST and transoceanic distance, when controlling for geographic distance, P = 0.134, r = 0.436). Isolation by distance plot across continuous stretches of land (range from 10 km to 160 km) has been found in other studies of flightless carabids, Carabus auratus , C. soleiri and C. problematicus using microsatellites and amplified fragment length polymorphism (AFLP) (Garnier et al ., ; Sander et al ., ; Gaublomme et al ., ). Our study is the first where IBD has been investigated across a water barrier in a flightless carabid species and it represents the first time that genome‐wide SNPs have been used in the population structuring of carabid beetles.…”

“…Instead, we found large‐scale patterns of the genomic population structuring that do not correspond to entities that we would interpret as being separated by obvious dispersal barriers. Presumably the observed population structuring is more a result of historical factors like, for example, different postglacial migration histories (Sander et al ., ; Matern et al ., ; Drees et al ., ). In particular, we consistently recovered a clade (SWE, BUN, TVE and TOF) consisting of southern Swedish and northeastern Danish mainland sites, despite these being separated by the Kattegat strait.…”

Larger carabid beetle species linked to open habitats have exhibited recent rapid decline in numbers throughout Europe. For example, Carabus arcensis is on the Danish Red List. Ability of C. arcensis to disperse across non‐habitable barriers in an island–mainland landscape has been evaluated through investigation of its population structure across Kattegat strait with special emphasis on the oceanic island Læsø. Based on admixture and statistical phylogenetic analyses of genome‐wide SNPs, data for C. arcensis comprising 3195 SNPs in 87 individuals from nine sample sites, three major lineages and six populations were found within the study area. These are the first genome‐wide SNPs data generated for carabid beetles. Contrary to predicted, water stretches did not seem to affect dispersal of C. arcensis to the island of Læsø, as isolation by distance plot showed no differences between sites connected by land and sites separated by an oceanic water gap. Unexpected high genetic diversity of the C. arcensis population on Læsø island has been observed calling for future research and explanation. High conservation priority in Denmark is suggested for smaller islands like Læsø.

Genetic Structure in the Seabuckthorn Carpenter Moth (Holcocerus hippophaecolus) in China: The Role of Outbreak Events, Geographical and Host Factors

Understanding factors responsible for structuring genetic diversity is of fundamental importance in evolutionary biology. The seabuckthorn carpenter moth (Holcocerus hippophaecolus Hua) is a native species throughout the north of China and is considered the main threat to seabuckthorn, Hippophae rhamnoides L. We assessed the influence of outbreaks, environmental factors and host species in shaping the genetic variation and structure of H. hippophaecolus by using Amplified Fragment Length Polymorphism (AFLP) markers. We rejected the hypothesis that outbreak-associated genetic divergence exist, as evidenced by genetic clusters containing a combination of populations from historical outbreak areas, as well as non-outbreak areas. Although a small number of markers (4 of 933 loci) were identified as candidates under selection in response to population densities. H. hippophaecolus also did not follow an isolation-by-distance pattern. We rejected the hypothesis that outbreak and drought events were driving the genetic structure of H. hippophaecolus. Rather, the genetic structure appears to be influenced by various confounding bio-geographical factors. There were detectable genetic differences between H. hippophaecolus occupying different host trees from within the same geographic location. Host-associated genetic divergence should be confirmed by further investigation.
