CarniTraits: Functional traits of the worlds Late Quaternary terrestrial mammalian predators

CarniTraits, a comprehensive functional trait database of all late Quaternary (~130,000 ybp) terrestrial mammalian carnivore species (149 species, >1kg body mass). The database contains the body mass, diet, locomotion, cooperative hunting, hunting habitat, hunting method, bone use, and hunting temporal activity patterns of all carnivores over the last ~130,000 years. We also include the IUCN status for all extant species and ground the database in a modern phylogeny and is thus compatible and easily interlinked with range maps published in PHYLACINE v1.2.1. CarniTraits is broadly applicable to assisting in local and macroecological studies, meta-analytic research, global syntheses, and paleoecological research. CarniTraits includes data on: <ul> <li>Body Mass</li> <li>Diet</li> <li>Scavenging behaviour</li> <li>Bone Consumption</li> <li>Locomotion</li> <li>Cooperative hunting</li> <li>Hunting habitat</li> <li>Hunting method</li> <li>Hunting time</li> <li>Brain mass</li> <li>Encephalisation Quotient</li> </ul> Each of these traits is fundamental to the ecological impact that carnivores have on terrestrial ecosystems. Trait data compiled represents the best available knowledge on the functional traits of late Quaternary hypercarnivorous mammals. As such, CarniTraits provides a tool for the analysis of carnivore functional diversity both past and present, as well as their effects on ecosystem dynamics. Each trait is accompanied by columns that describes the confidence in the data (notes), whether it was inferred and what level it was inferred from and the reference that the data was collected from.

The use of ancient DNA from sediment as a viable measure of Quaternary biodiversity within the Brecon Beacons National Park: a preliminary study

Contains 3 files. <ul> <li>One spreadsheet containing processed sequences -SM1_results_spreadsheets</li> <li>The other two containing Read 1 and Read 2 of the raw sequences (fastq).</li> </ul> Abstract A major challenge in the study of Quaternary environments is the variable preservation of paleoenvironmental evidence at many locations. Using ancient DNA from sediment cores (sedaDNA) allows the reconstruction of past biodiversity patterns at locations where traditional techniques often only reveal a partial picture. To test the feasibility of this approach, we analysed a sediment core from a peat bog, Traeth Mawr, in the Brecon Beacons National Park. Plant DNA was extracted and subjected to DNA metabarcoding, combining the use of universal PCR primers with Next-Generation Sequencing, to analyse a 7-143bp segment of the chloroplast trnL gene in five temporally separated sections of the core. Pollen analyses, from sections of the core, provide a comparison between the sedaDNA results and more traditional methods for studying the paleoenvironment. Partial reconstruction of past environmental variation was possible with the recovery of 113,682  DNA sequences representing six plant families, adding complementary results to traditional pollen analysis. This study is the first in the UK to successfully report the sequencing of ancient plant DNA from terrestrial sediments (currently a peat bog) using a DNA metabarcoding approach and exemplifies a promising area of research for addressing a range of questions about Quaternary environmental change.

Data for: Sedimentary ancient DNA and pollen reveal the composition of plant organic matter in Late Quaternary permafrost sediments of the Buor Khaya Peninsula (north-eastern Siberia)

Organic matter deposited in ancient, ice-rich permafrost sediments is vulnerable to climate change and may contribute to the future release of greenhouse gases; it is thus important to get a better characterization of the plant organic matter within such sediments. From a Late Quaternary permafrost sediment core from the Buor Khaya Peninsula, we analysed plant-derived sedimentary ancient DNA (sedaDNA) to identify the taxonomic composition of plant organic matter, and undertook palynological analysis to assess the environmental conditions during deposition. Using sedaDNA, we identified 154 taxa and from pollen and non-pollen palynomorphs we identified 83 taxa. In the deposits dated between 54 and 51 kyr BP, sedaDNA records a diverse low-centred polygon plant community including recurring aquatic pond vegetation while from the pollen record we infer terrestrial open-land vegetation with relatively dry environmental conditions at a regional scale. A fluctuating dominance of either terrestrial or swamp and aquatic taxa in both proxies allowed the local hydrological development of the polygon to be traced. In deposits dated between 11.4 and 9.7 kyr BP (13.4–11.1 cal kyr BP), sedaDNA shows a taxonomic turnover to moist shrub tundra and a lower taxonomic richness compared to the older samples. Pollen also records a shrub tundra community, mostly seen as changes in relative proportions of the most dominant taxa, while a decrease in taxonomic richness was less pronounced compared to sedaDNA. Our results show the advantages of using sedaDNA in combination with palynological analyses when macrofossils are rarely preserved. The high resolution of the sedaDNA record provides a detailed picture of the taxonomic composition of plant-derived organic matter throughout the core, and palynological analyses prove valuable by allowing for inferences of regional environmental conditions.
