Article Reference A peculiar case of intraspecific variability in the Chinese Notholca dongtingensis (Rotifera: Monogononta: Brachionidae)
We review the rare Chinese rotifer Notholca dongtingensis Zhuge, Kutikova & Sudzuki, 1998, including abundant material collected during the winter months of 2009–2011 in and around the man-made Dishui Lake Southeast of Shanghai, PR China. Both an SEM study of its trophi and an account of its intraspecific variability are provided. The latter consists in particular of a unique and previously unknown type of spine formation involving the anterolateral spines, a character previously considered morphologically constant and even diagnostic in Notholca and related genera. The observations indicate that phenotypic plasticity invoked by a plesiomorphic triggering mechanism is not per se connected to the type or position of structures developed, but may activate responses resulting in the formation of quite different, autapomorphic structures throughout monogonont Rotifera.

Article Reference A reconstruction of middle Holocene alluvial hardwood forests (Lower Scheldt River, northern Belgium) and their exploitation during the Mesolithic-Neolithic transition period (Swifterbant Culture, ca. 4500 – 4000 BC).
The analysis of a large number of charcoal fragments from fire places from a wetland camp site of the Mesolithic-Neolithic transition period (Swifterbant culture) now permits a detailed reconstruction of a middle Holocene riverine forest along the Lower Scheldt River (northern Belgium) and its exploitation between ca. 4,500 and 4,000 BC. The identified taxa point towards an alluvial hardwood forest (Querco-Ulmetum minoris Issler 1924) on the sand dune on which the camp site was situated, surrounded by alder carr. The results are compared with palynological and macrobotanical analyses from the same site and from contemporary sites within the area; the complementarity of these different types of data is discussed. The combination of all these datasets results in a detailed reconstruction of the environment and of its exploitation by the Swifterbant culture. The results also show that the Swifterbant people not only depended on these sand ridges for dry settlement locations, but also for firewood collection, gathering of edible plants and most probably for the collection of leaf fodder to feed livestock during winter time.

Inproceedings Reference What is inside this pit? Micro- and macrofaunal investigations at Chalcolithic and Early Bronze Age Ovçular Tepesi (Nakhchivan, Azerbaijan )
The site of Ovçular Tepesi is located in the southern Caucasus (Nakhchivan Autonomous Republic). Two main archaeological phases were recognised at the settlement, namely Late Chalcolithic and Early Bronze Age. More than 1160 litres of soil samples from pits and circular stone structures belonging to the different occupation layers were processed by flotation and analysed. This paper focuses on the zoological finds from these samples, in particular the remains of fish, large mammals and micromammals, in order to determine the function of the pits and structures. Moreover, the material gives an insight into the animal economy, hunting and fishing practices of the inhabitants, as well as the local environment. Thus far, it could not be established whether the differences detected in the species composition between the phases are related to chronology alone or if other factors, such as sample sizes and type of deposits, also played a role. Fish bones were very frequent at the site with cyprinids dominating. Among the large mammals, domestic animals were the most frequent while hunted species were rare. Sheep and goat herding seems to have been the principal subsistence strategy at this site. The small mammal community is composed of synanthropic taxa and, as a consequence, the species diversity was very low (six taxa). House mouse was the most abundant in each feature on the site.

Article Reference Mesocyclops thermocyclopoides species-group: redefinition and content
Within the genus Mesocyclops the thermocyclopoides species-group is defined on the basis of the presence of spiniform armature on the maxillar coxa. Examination of nineteen, mainly Palaeotropical species of Mesocyclops and nine representatives of the closely related genus Thermocyclops revealed, that the coxal part of the maxillar syncoxa of the species recently unified in the thermocyclopoides group is adorned with distinct rows of big spinules on its frontal surface. This character, with only one known exception in South Indian M. cf. papuensis, is absent in other species of Mesocyclops and all the Thermocyclops studied here. These species have no spinules on the maxillar coxa at all or very tiny scattered ones. © 1994 Kluwer Academic Publishers.

Article Reference Collagen Extraction from Recent and Fossil Bones: Quantitative and Qualitative Aspects
Type I collagen is the major protein in bones. The mineral matrix protects collagen from denaturation, thus permitting the recovery of large collagen peptides from fossil bones thousands or millions of years old. Collagen peptides are more or less denatured in fossil bones, with diagenetic alteration being the major cause of such denaturation. Classical extraction methods alter the remaining large collagen peptides by extensive solubilization. A method is described here that used shorter collagen solubilization times. Resulting collagen yields are favourably compared with classical methods. The size of the large peptide (10 kDa) fraction improves considerably. Combined with a particular concentration step, the use of this shorter solubilization technique should be useful for collagen analyses that necessitate large peptides, as in the case of palaeoimmunology. © 1995 Academic Press.
