“…Mean F IS values for studied populations ranged from 0.223 to 0.281. Although many Banksia species are typically considered as outcrossing plants (Broadhurst and Coates, 2004), our results indicate substantial amounts of self‐pollination and inbreeding within the same tree (i.e., correlated mating [range of mean F IS values without considering loci with null alleles: 0.352–0.588]) in the populations of B. integrifolia that we studied. Further studies that assess pollinator efficacy and mating systems are now required.…”

• Premise of the study: Microsatellite markers were developed to assess the level of genetic variation and population structure in Banksia integrifolia, a widespread species endemic to eastern Australia.• Methods and Results: We used next-generation sequencing approaches to identify and develop 11 polymorphic microsatellite markers with perfect tri- and tetranucleotide repeats. We tested these markers with 71 specimens from three populations. Observed and expected heterozygosities ranged from 0.0 to 0.875 and 0.0 to 0.763, respectively.• Conclusions: The developed markers will be valuable for studies of the population structure, mating system, and selection of provenances for restoration projects involving B. integrifolia.

“…Firstly, to demonstrate the use of the Bioclim variables and Ko¨ppen-Geiger surface components of the CliMond data set, we used MaxEnt (V3AE2AE2), a regression-based species distribution model (Phillips & Dudı´k 2008), applying the model exploration tools described by Elith, Kearney, & Phillips (2010), particularly multivariate environmental similarity surfaces (MESS) via maps and projection overlays. A conservation biology 'identification of additional suitable climatic regions' scenario was modelled for Banksia cuneata A.S.George (Proteaceae), an endangered shrub with a highly restricted native distribution in south-west Western Australia (Broadhurst & Coates 2004). Distribution data for B. cuneata populations were obtained from NatureMap (Department of Environment andConservation 2007-2011).…”

Summary1. Gridded climatologies have become an indispensable component of bioclimatic modelling, with a range of applications spanning conservation and pest management. Such globally conformal data sets of historical and future scenario climate surfaces are required to model species potential ranges under current and future climate scenarios. 2. We developed a set of interpolated climate surfaces at 10¢ and 30¢ resolution for global land areas excluding Antarctica. Input data for the baseline climatology were gathered from the WorldClim and CRU CL1AE0 and CL2AE0 data sets. A set of future climate scenarios were generated at 10¢ resolution. For each of the historical and future scenario data sets, the full set of 35 Bioclim variables was generated. Climate variables (including relative humidity at 0900 and 1500 hours) were also generated in CLIMEX format. The Ko¨ppen-Geiger climate classification scheme was applied to the 10¢ hybrid climatology as a tool for visualizing climatic patterns and as an aid for specifying absence or background data for correlative modelling applications. 3. We tested the data set using a correlative model (MaxEnt) addressing conservation biology concerns for a rare Australian shrub, and a mechanistic niche model (CLIMEX) to map climate suitability for two invasive species. In all cases, the underlying climatology appeared to behave in a robust manner. 4. This global climate data set has the advantage over the WorldClim data set of including humidity data and an additional 16 Bioclim variables. Compared with the CRU CL2AE0 data set, the hybrid 10¢ data set includes improved precipitation estimates as well as projected climate for two global climate models running relevant greenhouse gas emission scenarios. 5. For many bioclimatic modelling purposes, there is an operational attraction to having a globally conformal historical climatology and future climate scenarios for the assessments of potential climate change impacts. Our data set is known as 'CliMond' and is available for free download from http://www.climond.org.

“…Molecular markers have been used to determine the potential domestication events of wild boar (Larson et al 2005) and Asian wild rice (Lando et al 2006), and to track the colonization routes of penguins, thus identifying the places where they may have originated (Baker et al 2006). As to pest organisms, phylogeographical studies range from forest pests to field-cultivated plant pests, such as the winter pine processionary moth Thaumetopoea pityocampa (Salvato et al 2002), the spruce bark beetle Ips typographus L. (Stauffer et al 1999), the maize stalk borer Busseola fusca (Sezonlin et al 2006), the European corn borer Ostrinia nubilalis (Coates et al 2002a, b;Broadhurst & Coates 2004;Coates et al 2004;Dopman et al 2005;Malausa et al 2007), and the gypsy moth Lymantria dispar (Bogdanowicz et al 2000).…”

Population genetic structure of Chilo suppressalis (Walker) (Lepidoptera: Crambidae): strong subdivision in China inferred from microsatellite markers and mtDNA gene sequences

Chilo suppressalis (Walker) displays significant geographical differences in ecological preference that may be congruent with patterns of molecular variation. To test this, we collected and analysed 381 individuals of this species from cultivated rice at 18 localities in China during the rice-growing season of 2005-2006. We used four microsatellite DNA markers and four mitochondrial DNA gene fragments. We found that this species is highly differentiated, coupled with an estimated population expansion date of at least 60 000 bp. Phylogenetic analyses, Bayesian clustering, and phylogeographical analyses of statistical parsimony haplotype network consistently divided the populations into three clades: a central China (CC) clade, a northern plus northeastern China (NN) clade and a southwestern China (SW) clade. Analysis of molecular variance indicated a high level of geographical differentiation at different hierarchical levels [F(ST) for microsatellite markers, COI, COII, 16S and ND1 is 0.06004 (P < 0.0001), 0.27607 (P < 0.0001), 0.22949 (P < 0.0001), 0.19485 (P < 0.0001) and 0.29285 (P < 0.0001), respectively]. Isolation by distance appeared among the samples from within China (r = 0.404, P = 0.0002); N(e)m values estimated using a coalescent-based method were small (< 2 migrants per generation), suggesting that the observed levels of differentiation are a result of migration-drift equilibrium. Our results imply that the genetic differentiation of this borer, which is approximately in accordance with its observed number of generations per year in different Chinese geographical regions, is probably attributed to climatic and/or geological events (e.g. the last glacial maximum) and subsequently strengthened by the domestication of rice.
