Article Reference Exploring species diversity within the amphipod family Iphimediidae using DNA-based delimitation, traditional and 3D-Geometric Morphometrics
As an isolated ocean at the end of the thermal continuum, the Southern Ocean hosts a highly endemic cold-adapted marine fauna. However, this unique biota is now challenged by climate-related changes, as some parts of Antarctica are the fastest warming areas on Earth. In order to monitor and mitigate climate-induced changes, a baseline knowledge of species biodiversity and distributions is mandatory. However, this knowledge is currently insufficient for most Southern Ocean taxa, as the actual number of species is still likely to be greatly underestimated. For instance, most of the geographically widespread to circum-Antarctic amphipod species that have been subjected to molecular scrutiny were revealed to be complexes of similar species with a more restricted distribution range. In this study, we reconstructed a novel molecular phylogeny of Antarctic Iphimediidae and used a range of DNA-based species delimitation methods (bPTP, GMYC, ABGD) to explore species diversity. Furthermore, traditional and 3D-geometric morphometric methods were applied on micro-CT scans to characterize patterns of morphological variation within and among clades and DNA-based putative species. For two of the species complexes, namely Gnathiphimedia sexdentata and Echiniphimedia hodgsoni, the shapes of selected anatomical traits of potential taxonomic value at the species level were quantified: (i) a spine-like tooth, (ii) the head, (iii) the coxa 4 and (iv) the first article of Antenna I peduncle. Our results revealed that ten nominal iphimediid species are complexes of multiple species, most of which can be distinguished by small but consistent morphological differences. Ten of these new species were formally described: Stegopanoploea brevidentata sp. nov., Maxilliphimedia acutilobata sp. nov., Maxilliphimedia oliveri sp. nov., Echiniphimedia spinosior sp. nov., Echiniphimedia maxima sp. nov., Iphimediella longidentata sp. nov., Iphimediella brachyodonta sp. nov., Iphimediella longilobata sp. nov., Labriphimedia adeliae sp. nov., and Labriphimedia anneninae sp. nov. Altogether, molecular and morphometric methods were combined to revise species diversity within the iconic Antarctic Iphimediidae, increasing the number of species from 39 to 49, with 14 additional putative species requiring further study for formal description.

Inproceedings Reference Exploring the Morphometric Characteristics of sheep breeds in the Ancient Near East
The multidisciplinary project Evosheep studies the origin and evolution of ancient sheep breeds by means of archaeozoology, geometric morphometrics, genetics, iconography and epigraphy in the ancient Near East from the six millennium BCE. This approach conducted on ancient breeds is completed by work on modern breeds from Near and Middle East and East Africa to provide new biometric and genetic reference records more adequate than European races for further scientific research. This osteological reference offers a measurement baseline for comparison with the archaeological data to explore the diversity patterns of the different domestic sheep populations across the Ancient Near East. This paper compares the diversity of sizes, allometry, and body parts proportions of sheep from archaeological assemblages using the Log Size Index, the Log Shape Ratio, and multivariate analyses. This study will focus on Chalcolithic and Bronze Age sites from the Levant, Mesopotamia, Iran, and South Caucasus.

Inproceedings Reference Octet Stream Exploring the potential of Lake Hamana (Shizuoka Prefecture, Japan) to hold a long and reliable sedimentary record of paleo-earthquakes and -tsunami along the Nankai-Suruga Trough.
Coastal Lake Hamana is located near the convergent tectonic boundary of the Nankai-Suruga Trough, along which the Philippine Sea slab subducts underneath the Eurasian Plate, giving rise to repeated tsunamigenic megathrust earthquakes (Mw≥8). A good understanding of the earthquake- and tsunami-triggering mechanisms in terms of rupture mode and recurrence pattern in time and space, is crucial in order to better estimate the complexity of seismic risks for the densely populated Enshu-nada coast. Based on existing historical data of paleoseismicity (last ~1300 years), the easternmost segment (Tōkai segment) of the Nankai-Suruga Trough appears to exhibit a seismic gap and is expected to rupture in the near future, causing the next “Tōkai earthquake”. Studying the sedimentary infill of Lake Hamana may help to fine-tune hazard assessment in the area of interest. Thanks to its extensive accommodation space, the Hamana lake basin is considered to be a good archive of past “big wave” events. Fieldwork (Oct.-Nov. 2014) comprised a reflection-seismic survey for imaging the lake’s stratigraphic features, based on which favourable locations for gravity coring were selected. A systematic sampling of bottom sediments from different sites enables us to evaluate vertical as well as lateral changes in depositional environment, including event deposits generated by tsunamis and tropical storms (i.e. typhoons). An important part of the study is dedicated to qualitatively distinguish sedimentary facies of storm deposits from the ones generated by tsunamis, since this is an essential step in correctly assessing future hazards. For identification of marine tsunami incursions, a set of sedimentological, geophysical, geochemical and micropaleontological analyses are applied on the core sediments in a multi-proxy approach. Radionuclide dating provides the necessary timeframe and information on prevailing sedimentation rates. Sites bearing the potential of recording complete and long event histories will be sampled with long cores.

For identification of marine incursions caused by tsunami waves, a set of sedimentological, geophysical, geochemical and micropaleontological analyses are applied on the cored sequences. Radionuclide dating provides the necessary timeframe and information on prevailing sedimentation rates. Sites with the potential of recording complete and long event histories will be sampled with long cores during the upcoming field season (autumn 2015).
