Polymerase chain reaction (PCR) products corresponding to 803 bp of the cytochrome oxidase subunits I and II region mitochondrial DNA (mtDNA COI-II) were deduced consist multiple haplotypes in three Sitobion species. We investigated molecular basis these observations. PCR cloned, six clones from one individual per species sequenced. In each individual, sequence was found commonly, but also two or divergent sequences seen. The shown be nonmitochondrial by sequencing purified mtDNA Southern...
Abstract Translocations are being increasingly proposed as a way of conserving biodiversity, particularly in the management threatened and keystone species, with aims maintaining biodiversity ecosystem function under combined pressures habitat fragmentation climate change. Evolutionary genetic considerations should be an important part translocation strategies, but there is often confusion about concepts goals. Here, we provide classification translocations based on specific goals for both...
Abstract Thousands of small populations are at increased risk extinction because genetics and evolutionary biology not well‐integrated into conservation planning–a major lost opportunity for effective actions. We propose that if the outbreeding depression is low, default should be to evaluate restoration gene flow inbred diploid organisms were isolated by human activities within last 500 years, rather than inaction. outline elements a scientific‐based genetic management policy fragmented...
Aim The mesic biome, encompassing both rain forest and open sclerophyllous forests, is central to understanding the evolution of Australia's terrestrial biota has long been considered ancestral biome continent. Our aims are review refine key hypotheses derived from palaeoclimatic data fossil record that critical Australian biota. We examine predictions arising these using available molecular phylogenetic phylogeographical data. In doing so, we increase highlight deficiencies fruitful areas...
Genomics promises exciting advances towards the important conservation goal of maximizing evolutionary potential, notwithstanding associated challenges. Here, we explore some complexity adaptation genetics and discuss strengths limitations genomics as a tool for characterizing potential in context management. Many traits are polygenic can be strongly influenced by minor differences regulatory networks epigenetic variation not visible DNA sequence. Much this critical is difficult to detect...
Genetic diversity underpins the ability of populations to persist and adapt environmental changes. Substantial empirical data show that genetic rapidly deteriorates in small isolated due drift, leading reduction adaptive potential fitness increase inbreeding. Assisted gene flow (e.g. via translocations) can reverse these trends, but lack on loss fear impairing population "uniqueness" often prevents managers from acting. Here, we use riverscape analyses simulations explore consequences...
All genetic markers are estimators of DNA nucleotide sequence variation. Rather than obtaining data, it is cheaper and faster to use techniques that estimate variation, although this usually results in the loss some information. SSCP (single-stranded conformation polymorphism) offers a sensitive but inexpensive, rapid, convenient method for determining which samples set differ sequence, so only an informative subset need be sequenced. In short, most variation can detected with relatively...
In a previous study, samples of the grain aphid Sitobion avenae (F.) were collected from wheat and adjacent cocksfoot hosts in population thought to be primarily parthenogenetic, DNA individual aphids was analysed with multilocus technique. Here we have applied single‐locus microsatellites mitochondrial marker subset same extracts, made several additional inferences about important genetic processes S. . Microsatellite analysis indicated very high levels genic genotypic variation. fell into...
The effects of habitat fragmentation on processes within and among populations are important for conservation management. Despite a broad spectrum lifestyles the significance many reptiles, very little work fine-scale population genetics has been carried out this group. This study examines dispersal patterns rock crevice-dwelling lizard, Cunningham's skink (Egernia cunninghami), in naturally vegetated reserve an adjacent deforested site. Both genotypic genic approaches were employed, using...
As French populations of the aphid Sitobion avenae exhibit a range reproductive modes, this species provides good opportunity for studying evolution breeding system variation. The present analysis combined ecological and genetic investigations into spatial distribution variation in mode. Reproductive mode was characterized 277 lineages S. from France, these aphids were scored five microsatellite loci. analyses revealed strong geographical partitioning systems, with obligate asexuals mostly...
Single-locus microsatellite variation correlated perfectly with chromosome number in Sitobion miscanthi aphids. The microsatellites were highly heterozygous, up to 10 alleles per locus this species. Despite considerable allelic variation, only seven different S. genotypes discovered 555 individuals collected from a wide range of locations, hosts and sampling periods. Relatedness between suggests two successful colonizations Australia. There was no evidence for genetic recombination so the...
Throughout the Southern Hemisphere many terrestrial taxa have circum-Antarctic distributions. This pattern is generally attributed to ongoing dispersal (by wind, water, or migrating birds) relict Gondwanan Few of these extant representatives in Antarctica, but such would contribute our understanding evolutionary origins continental Antarctic fauna. Either survived harsh climate cooling Antarctica over last 23 Myr (Gondwanan/vicariance origin) they dispersed there more recently (<2 MYA). In...
Evolutionary trajectories of codistributed taxa with comparable ecological preferences and dispersal abilities may be similarly impacted by historical landscape-level processes. Species' responses to changes in a shared biogeographic landscape purely concerted, completely independent, or classified as falling within an intermediate part the continuum bounded these two extremes. With sufficient molecular data, temporal contrasts congruence among respect can made. Such provide insights into...
Diversifying selection on metabolic pathways can reduce intraspecific gene flow and promote population divergence. An opportunity to explore this arises from mitonuclear discordance observed in an Australian bird Eopsaltria australis. Across >1500 km, nuclear differentiation is low latitudinally structured by isolation distance, whereas two highly divergent, parapatric mitochondrial lineages (>6.6% ND2) show a discordant longitudinal geographic pattern experience different climates....
A widely-used approach for screening nuclear DNA markers is to obtain sequence data and use bioinformatic algorithms estimate which two alleles are present in heterozygous individuals. It common practice omit unresolved genotypes from downstream analyses, but the implications of this have not been investigated. We evaluated haplotype reconstruction method implemented by PHASE context phylogeographic applications. Empirical datasets five non-coding loci with gametic phase ascribed molecular...
