Chromosome Complement: A Fertile Hybrid between Equus priewalskii and Equus caballus

open access: yesScience, 1966
At the Zoological Garden of Antwerp it has been proved that when Equus prjewalskii is crossed with E. caballus the offspring is fertile. As expected, its diploid chromosome number is 65. The morphological differences between the parental and the offspring karyotypes are not great; therefore ...

Same data, different results? Machine learning approaches in bioacoustics

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Automated acoustic analysis is increasingly used in behavioural ecology, and determining caller identity is a key element for many investigations. However, variability in feature extraction and classification methods limits the comparability of results across species and studies, constraining conclusions we can draw about the ecology and ...

Food web reconstruction of Barmaky, the oldest post‐LGM hunter‐gatherer site in north‐western Ukraine

open access: yesBoreas, EarlyView.
The site of Barmaky currently marks the oldest Epigravettian occupation of north‐western Ukraine shortly after the Last Glacial Maximum (LGM), dated to around 19 cal. ka BP. Stable isotope analyses of bone collagen from six terrestrial mammals and two bird species show a comparatively highly structured palaeo‐food web.
