“…The two frequency-based assignment tests we applied consisted of the allele frequency assignment approach (Paetkau et al 1995(Paetkau et al , 1999(Paetkau et al , 2004 and the Bayesian assignment method (Rannala and Mountain 1997) as implemented in Geneclass v2 (Piry et al 2004). Both assignment tests are commonly used in genetic analyses (Kraaijeveld-Smit et al 2005;Kim et al 2006;MacAvoy et al 2007;Zamudio and Wieczorek 2007). For the Bayesian assignment tests an assignment threshold of P \ 0.01 was applied using the leave one out approach and for the Paetkau et al (1995) procedure a default frequency for missing alleles was set at 0.01.…”

Individual-based clustering (IBC) methods have become increasingly popular for the characterization and delineation of genetic population units for numerous species. These methods delineate populations based on the genetic assumptions of a breeding unit which may provide a better representation of the behaviour of the species. The increasing use of IBC has resulted in the development of several analytical models all of which vary in their theoretical assumptions to infer genetic population structure. In this paper, we report a comparative strategy utilizing three IBC methods to characterize the spatial genetic structure of the boreal population of woodland caribou (Rangifer tarandus caribou) in central Canada. In addition, we implement both tests for isolation-by-distance (IBD) and frequency-based assignment tests to validate the consensus genetic clusters as defined by IBC. We also compare indirect metrics of genetic diversity and gene flow using both a priori defined herds and the IBC defined populations. Although our results show some concordance between both pre-defined herds and IBC derived genetic clusters, the IBC analyses identified a cluster that was cryptic to observation-based caribou herds and found no difference between several adjacent herds. By comparing multiple IBC methods and integrating both IBD and indirect genetic diversity metrics a posteriori, our strategy provides an effective means to delineate wildlife population structure and accurately assess genetic diversity and connectivity.

“…Molecular markers are widely used to study invasive species, with applications ranging from assessing genetic variation (Roderick 1996;Sakai et al 2001), to reconstructing invasion history (Elderkin et al 2004), identifying population origin (population assignment tests) and the number of introductions (Grapputo et al 2005), and developing control strategies (Szalanski and Owens 2003;Conord et al 2006;Kim et al 2006;Fu et al 2010). Understanding the geographic origin, population biology and genetic variation of an invasive species can provide important information on suitable habitat, potential location(s) of effective biological control agents, or predict the effectiveness of a control agent (Allendorf and Lundquist 2003;Sakai et al 2001;Kambhampati and Rai 1991;Lee 2002;Scheffer and Grissell 2003).…”

“…Additionally, characterization of population genetic structure within an invasive species provides benchmark data for comparison with similar data from other invasive species. Population assignment tests allow the estimation of the probability that a particular individual originated from each of a number of possible source populations, and have been applied broadly to estimate the origin of invasive species (Bonizzoni et al 2001;Genton et al 2005;Tsutsui et al 2001;Kim et al 2006), confirm the population structure of native and/or invasive populations (Elderkin et al 2004;Paupy et al 2004), and to assess population structure to design eradication strategies (Abdelkrim et al 2005).…”

Genetic analysis of emerald ash borer (Agrilus planipennis Fairmaire) populations in Asia and North America

Emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is an invasive pest of North American ash (Fraxinus spp.) trees first discovered outside of its native range of northeastern Asia in 2002. EAB spread from its initial zone of discovery in the Detroit, Michigan and Windsor, Ontario metropolitan areas, in large part, from inadvertent human-assisted movement of infested ash materials. EAB infestations are now known in 15 US states and two Canadian provinces. The primary goal of this study was to use molecular markers to characterize the population genetic structure of EAB in its native and introduced range. This information may provide valuable insights on the geographic origin, potential host range, invasion potential, and additional biological control agents for ongoing management efforts of this destructive wood-boring beetle. EAB were collected from 17 localities in its native Asian range and from 7 localities in North America, and population structure analyzed using mtDNA gene sequences, AFLP fingerprints, and alleles at 2 microsatellite loci. Analysis of mtDNA cytochrome oxidase subunit I gene (COI; 439 bp) sequences revealed all North American individuals carry a common mtDNA haplotype also found in China and South Korea. Additional mtDNA haplotypes observed in China and South Korea differed from the common haplotype by 1-2 nucleotide substitutions and a single individual from Japan differed by 21 nucleotide changes (4.8%). Analysis using AFLP fingerprints (108 loci) indicated Asian populations were more highly variable, yet had less overall population structure, than the North American populations. North American populations appear most closely related to populations in our sample from the Chinese provinces of Hebei and Tianjin City. Further, population assignment tests assigned 88% of the individual beetles from North America to either Hebei or Tianjin City.

“…, but long distance dispei'sal over several hundreds of kilometers is not unusual (Guerra 1988;Spurgeon et al 1997;Sappington 2004a,b, 2006;Kim et al 2006Kim et al , 2010Westbrook et al 2010a). Reintroduction of weevils to eradication zones where populations have been eliminated or substantially suppressed is a perpetual concern because of the expense and difficulty involved in eradicating new infestations (Culin et al 1990, Kim et a!.…”

ABSTRAGT An existing microsatellite genotype database has been used for several years in population genetic assignment analyses of boll weevils, Anthononiu.'í grandis grandis-Boheman (GOleoptera: Gurculionidae), captured in eradication zones. It is important to update it in case of changes in genotype frequency at any of the locations over time. Such changes at neutral loci could be caused by drift, immigration, or population bottlenecks. We examined alíele frequency distribution for 10 microsatellite loci to determine genetic differentiation among 10 boll weevil populations sampled from Texas and Mexico in 2009. In addition, temporal changes in genetic composition were examined in the eigbt populations for which samples were available from previous years. Svibstantial levels of spatial genetic structvu'e were observed, witb the 10 populations clustering as four major gi-oups. Pairwise F^^estimates in 2009 samples ranged from 0.001 (College Station-Cameron) to 0.492 (College Station-Ojinaga). There was little change in genetic profiles over time at four of the eigbt locations. Thus, for those four locations, genotype and alíele fi'equency data can be pooled over the two sample dates, which will provide greater statistical power in future population assignment tests. However, genetic profiles changed substantially at Ojinaga, and to a lesser extent at Uvalde, Cameron, and Rosales, so tlie 2009 genotype data should be substituted in futvn-e analyses. Finally, populations from two new locations, Brownsville and Lockhart, TX, were sampled, genotyped, and added to the database. The addition of Lockhart is particularly important given its suiprisingly high diffeientiation from the relatively neai'by populations of Cameron and Uvalde.
