Horse domestication revolutionized warfare and accelerated travel, trade, the geographic expansion of languages. Here, we present largest DNA time series for a non-human organism to date, including genome-scale data from 149 ancient animals 129 genomes (≥1-fold coverage), 87 which are new. This extensive dataset allows us assess modern legacy past equestrian civilizations. We find that two extinct horse lineages existed during early domestication, one at far western (Iberia) other eastern...
The feasibility of genome-scale studies from archaeological material remains critically dependent on the ability to access endogenous, authentic DNA. In majority cases, this represents a few per cent DNA extract, at most. A number specific pre-extraction protocols for bone powder aimed improve ancient recovery before library amplification have recently been developed. Here, we test effects combining two such protocols, bleach wash and predigestion step, 12 samples Atlantic cod domestic horse...
Significance A rich archaeological record of fish-bone remains testifies to the millennia-long human exploitation natural resources oceans. In Europe, historical evidence demonstrates that an extensive international industry developed during Middle Ages exported preserved cod from Lofoten Archipelago, northern Norway, expanding urban centers around North and Baltic Sea regions. The early origins this iconic exchange, however, have long been debated. We genetically trace ancestry Viking Age...
Abstract Habitat fragmentation can significantly affect mating and pollen dispersal patterns in plant populations, although the differential effects of various aspects are poorly understood. In this study, we used eight microsatellite loci to investigate effect on system within one large small population remnants Banksia sphaerocarpa var. caesia , a bird‐pollinated shrub southern agricultural region Western Australia. The had much larger neighbourhood size lower selfing rate, maternal pool...
Abstract The majority of archaeological plant material is preserved in a charred state. Obtaining reliable ancient DNA data from these remains has presented challenges due to high rates nucleotide damage, short fragment lengths, low endogenous content and the potential for modern contamination. It been suggested that high-throughput sequencing (HTS) technologies coupled with enrichment techniques may overcome some limitations. Here we report findings HTS target on four important crops...
Plant species distributed across terrestrial islands can show significant genetic divergence among populations if seed and pollen dispersal are restricted. We assessed the connectivity between of Grevillea georgeana, restricted to seven disjunct inselbergs in semi-arid Western Australia. The phylogeographical pattern population genetics were determined using sequence data from two plastid DNA intergenic spacers ten nuclear microsatellite loci. markers indicated high differentiation majority...
Abstract Translocation programmes are increasingly being informed by genetic data to monitor and enhance conservation outcomes for both natural established populations. These provide a window into contemporary patterns of diversity, structure relatedness that can guide managers in how best source animals their translocation programmes. The inclusion historical samples, where possible, strengthens monitoring allowing assessment changes diversity over time providing benchmark future...
Horses are the most common grave goods found in Icelandic Viking Age graves. Horse skeletons have previously been sexed based on pelvis shape and presence of canine teeth male horses over 4–5 years age. Morphological data has shown that all from burials were amenable to sexing male. Yet use morphological methods determine sex is problematic since they rely finding a well-preserved and/or robust teeth. Furthermore, quantitative underlying features horse used for lacking reported occur mares....
The Banded Iron Formations (BIFs) of south-western Australia are terrestrial islands characterized by high species richness and endemism. Regional endemics occur across multiple formations without inhabiting the intervening landscape matrix. We investigated whether occurrence on BIF has led to genetic differentiation among eight known populations regional endemic, Banksia arborea. Genetic structure was assessed using three chloroplast DNA sequence markers 11 nuclear microsatellite loci....
The Yilgarn Banded Iron Formations of Western Australia are topographical features that behave as terrestrial islands within the otherwise flat, semi-arid landscape. formations characterised by a high number endemic species, some which distributed across multiple without inhabiting intervening These species provide an ideal context for phylogeographic analysis, to investigate patterns genetic variation at both spatial and temporal scales. We examined in spirostreptid millipede, Atelomastix...
Plant species often exhibit genetic structure at multiple spatial scales. Detection of this may depend on the sampling strategy used. We intensively sampled a common, naturally patchy Banksia within 200 km2 region, in order to assess patterns diversity and In total, 1321 adult shrubs from 37 geographical populations were genotyped using eight highly polymorphic microsatellite markers developed for species. Genetic was detected three First, we identified stark unexpected division landscape...
Phylogeographic studies can be used as a tool to understand the evolutionary history of landscape, including major drivers species distributions and diversity. Extensive research has been conducted on phylogeographic patterns found in northern hemisphere landscapes that were affected by glaciations, yet body literature for older, unaffected is still underrepresented. The Pilbara region north-western Australia an ancient vast landscape topographically complex, consisting plateaus, gorges,...
Abstract The impact of Quaternary glaciation on the development phylogeographic structure in plant species is well documented. In unglaciated landscapes, patterns tend to reflect processes relating persistence and stochasticity, yet other factors, associated with palaeogeographical history landscape, including geomorphological events, can also have a significant influence. landscape south‐western Western Australia an ideal location observe these ancient drivers lineage diversification,...
Abstract Microsatellite markers were developed for the Australian bird‐pollinated woody shrub Banksia sphaerocarpa var. caesia to study gene flow among populations in a highly fragmented landscape. Eight loci developed, and sample of 40 individuals from one population, number alleles per locus ranged five 21 observed heterozygosities 0.385 0.914. All eight showed independent inheritance. Analysis open‐pollinated progeny arrays confirmed Mendelian inheritance at seven loci, while null...
