Aurochs (Bos primigenius) are the wild ancestors of the domesticated taurine cattle (Bos taurus). During the Holocene, populations of aurochs gradually declined until their extinction at the turn of the 17th century. DNA data suggest that domestic cattle in Europe descended from Near East aurochs that were domesticated and brought to Europe by the first farmers during the Neolithic period. Hybridization occurred more recently in Europe between domestic cattle and local wild aurochs. Most aurochs can be distinguished from domestic cattle osteometrically, but large-sized domestic cattle may be misidentified as aurochs. Based on mitochondrial DNA, most European aurochs differ from domestic cattle (haplogroup “P” versus “T”). With the aim to provide new data on the former distribution of aurochs in Europe, we used mitochondrial DNA to identify large bovid bones attributed to aurochs and dating from Epipaleolithic to medieval times. DNA was extracted from the bones of 11 specimens from Belgium in an ancient DNA lab. Shotgun DNA sequencing provided raw reads comprising 0.02-10% of endogenous DNA. For three samples, reads covered 74-98% of the bovid mitochondrial genome and enabled the identification of one aurochs from the Bronze Age (haplogroup “P”) and two cows from Roman and medieval times (haplogroup “T”). Among the other samples (covering 2-18% of the mitogenome), three Roman specimens could be assigned to the haplogroup “T” based on a few diagnostic positions. This study provides the first mitogenomic data for a Belgian aurochs and contributes to the identification of exceptionally large Roman bovid remains.No publisherRBINS Collection(s)Open AccessPDF availableAbstract of an Oral Presentation or a Poster2023/09/12 10:40:00 GMT+1Inproceedings ReferenceUses of DINEOF algorithm (Data interpolation with Empirical Orthogonal Functions) for reconstruction and analysis of incomplete satellite databases over the North Sea and the Mediterranean, synthesis from the RECOLOUR project.

https://biblio.naturalsciences.be/library-1/rbins-staff-publications/duplicates/a83b9226d4174a5fab35326ba895cd89
The shape of water-leaving reflectance spectra in the near infrared range 700-900nm is almost invariant for turbid waters and has been analysed and tabulated as a similarity spectrum by normalisation at 780nm. This similarity spectrum is used here for the quality control of seaborne reflectance measurements and for the improvement of sky glint correction. Estimates of the reflectance measurement error associated with imperfect sky glint correction from two different wavelength pairs are shown to be nearly identical. A demonstration of residual reflectance correction for data collected in cloudy, high wave conditions has shown that this correction removes a large source of variability associated with temporal variation of the wave field. The error estimate applied here to seaborne measurements has wide-ranging generality and is appropriate for any water-leaving reflectance spectra derived from seaborne, airborne or satellite borne sensors provided suitable near infrared bands are available.No publisherAbstract of an Oral Presentation or a Poster2016/06/08 10:36:19 GMT+1Inproceedings ReferenceUse of the near infrared similarity reflectance spectrum for the quality control of remote sensing data

https://biblio.naturalsciences.be/library-1/rbins-staff-publications/doxaran_use_2010
A multi-sensor algorithm is applied to MODIS and MERIS satellite data in order to quantify suspended particulate matter (SPM) in the Yangtze River plume (East China Sea). Several atmospheric correction methods are tested; a simple but operational method is finally selected as appropriate for MODIS, MERIS and GOCI satellite data. As most of the methods for atmospheric corrections of satellite data fail over such highly turbid waters, an adaptation of the black pixel assumption is used to correct for the aerosol contribution. The retrieved seawater reflectance at red wavebands appears as the most sensitive to SPM concentrations but tends to saturate at concentrations beyond 100 mg.l(-1). By opposition the near-infrared seawater reflectance does not saturate even at extremely high concentrations of 1000 mg.l(-1). Overall, the most robust relationship between the SPM concentration and seawater reflectance is obtained considering a spectral ratio between the near-infrared (e. g., 850 nm) and visible (e. g. 550 nm). This relationship is applied to atmospherically corrected ocean color satellite data to retrieve SPM concentrations in the Yangtze River plume. Results show that ocean color satellite data can be used to study the seasonal dynamics of SPM and better understand the role played by the main physical processes involved (river discharge, tidal cycles, wind and regional circulation).No publisherAbstract of an Oral Presentation or a Poster2016/06/08 10:36:08 GMT+1Inproceedings ReferenceUpper stability limit of authigenic monazite in the Rocroi Inlier

https://biblio.naturalsciences.be/library-1/rbins-staff-publications/inproceedingsreference.2013-02-13.1767103912
Since Alvarez et al. (1980) found new evidence for the impact of catastrophic events on earth’s biota, hypothesis and theories explaining the fossil record (re)gained a lot of attention. The extraterrestrial origin of the anomalous iridium concentrations seemed highly controversial at first, but nowadays the Chicxulub ‘accident’ has become the marker for the start/base of the Paleogene. Its pivotal role in the Mesozoic-Cenozoic faunal turnover cannot be refuted (Schulte et al 2010). However, alternative theories remain being published. Of these, the Deccan volcanism with its widespread flood basalts stepped prominently forward as one of the main triggers, especially when trying to explain the gradual diversity decline within the fossil record. The inconsistencies between the proposed theories generally root in too narrowly geographically and geologically spread datasets. This applies to most fossil groups, and especially to the ammonoids (Class Cephalopoda, °Early Devonian – †Late Cretaceous). A compilation of ammonoid occurrences of Late Maastrichtian age published by Kiessling & Claeys (2002) evidenced the lack of a globally well distributed dataset. In this compilation, North Africa was left as a blind spot, while Tunisia had been the centre of the K/Pg mass extinction debate for almost three decades, e.g. with the definition of the GSSP for the base of the Paleogene at El Kef. Both at the GSSP and several other sections in the Tunisian Trough Basin, ammonoids were found within the topmost meters of the Maastrichtian, until very close to the K/Pg boundary level. About 900 uppermost Maastrichtian ammonoids were collected, all from within the last 420.000 years of the Cretaceous. With 22 species on record, belonging to 18 genera and 10 families, and with representatives of each of the four large ammonoid suborders (Phylloceratina, Lytoceratina, Ammonitina and Ancyloceratina), the Tunisian fauna demonstrates that ammonoids were both taxonomically and morphologically diverse until their very end. An updated version of the compilation of latest Maastrichtian ammonoid occurrences documents at least 53 species, 29 genera and 13 families in the ultimate half million year of the Cretaceous, in many more localities and occurring in a wide variety of settings. When the Tunisian ammonoid species richness data are plotted next to all time constraints of the possible causes, the possibility of Deccan flood basalt volcanism negatively influencing ammonoid diversity must be refuted. A major extinction caused by the Chicxulub impact seems the most plausible theory at present. Through inducing a mass kill of the marine plankton, the juvenile ammonoids lost their primary food source leading to their final extinction.
