    MiTiSegmenter: Software for high throughput segmentation and meshing of microCT data in microtiter plate arrays by Kendrick Connah, Buckley Michael, Charlotte Brassey

    Published 2022-01-01
    “…We foresee MiTiSegmenter as particularly useful when incorporated into workflows that ultimately require the destructive testing of specimens, including sampling for ancient DNA and proteomics. The software may also play an important role in national museums' ongoing mass digitisation efforts, facilitating the high-speed archiving of specimen 3D morphology across extensive collections with very minimal user intervention or prior training. • We present MiTiSegmenter, a software package for semi-automated image processing and segmentation of array-based batch microCT data. • Implemented in Python, MiTiSegmenter expedites cropping, meshing and exporting samples within stacked microtiter plates, facilitating the rapid digitisation of hundreds-thousands of samples per scan. • We illustrate MiTiSegmenter's capabilities when applied to bulk archiving of valuable zooarchaeological and palaeontological remains…”

    Searching for archaic contribution in Africa by Santander, C, Montinaro, F, Capelli, C

    Published 2019
    “…</p> <p><strong>Conclusion:</strong> In light of the caveats with implementing current archaic introgression detection methods in Africa, we recommend future studies to concentrate on unravelling the complicated demographic history of Africa through means of ancient DNA where possible and through more focused efforts to sequence modern DNA from more representative populations across the African continent.…”

    Evolution of endogenous retrovirus-like elements of the woolly mammoth (Mammuthus primigenius) and its relatives. by Greenwood, A, Lee, F, Capelli, C, DeSalle, R, Tikhonov, A, Marx, P, MacPhee, R

    Published 2001
    “…Conventionally, empirical studies of proviral amplification and diversification have been limited to extant species, but taxa having good Quaternary fossil records could potentially be investigated using the techniques of "ancient" DNA research. To examine evolutionary parameters of ERV-Ls across both time and taxa, we characterized this proviral class in the extinct woolly mammoth (Mammuthus primigenius) and living elephants, as well as extant members of the larger clade to which they belong (Uranotheria, a group containing proboscideans, sirenians, hyraxes, and their extinct relatives). …”
