Article Reference Size of the lower carnassial in the arctic and the red fox from Late Pleistocene in Belgium compared to other ancient and extant populations
Lengths, widths, and size proportions (length to width) of the lower carnassial were measured in 45 teeth of the arctic fox and 35 teeth of the red fox from Belgium radiocarbon dated to 46 640–14 120 ka BP. Data the Late Pleistocene foxes from Belgium were compared to 20 ancient and extant populations form Europe, Asia, and North America. The Pleistocene arctic fox from Belgium showed larger carnassial than in all recent samples of this species, whereas the Belgian fossil red foxes were characterized by the carnassial size comparable to that of the recent Siberian red foxes. Both fox species from the Pleistocene of Belgium showed the highest index of the carnassials length to width, which means increase in carnivorous adaptation. We conclude that the higher level of carnivorous specialization reached by the Belgian arctic and red foxes at the end of the Late Pleistocene reflected their scavenging on kills of large carnivores and human hunters (remains of megafauna). Harsh environmental conditions of that period and specific composition of ecosystems led to adapting to a more carnivorous food niche in both foxes.

Article Reference Predynastic and Early Dynastic plant economy in the Nile Delta: archaeobotanical evidence from Tell el-Iswid
The large-scale excavation at the prehistoric site of Tell el-Iswid made it possible to undertake a systematic archaeobotanical study of different structures covering the Predynastic and Early Dynastic period (Lower Egyptian Cultures (Buto II) to Naqada III Culture. Here we present the results of the analysis of carpological remains preserved mostly in charred state and coming from 62 samples processed by manual flotation, with total volume of 615 litres and containing a total of 9672 identifiable and quantifiable items. Further ca. 650 wood fragments (or woody vegetative remains) were subject to anthracological analysis. Besides the aim of overall characterising and exploring the plant economy of the site, the macrobotanical assemblages were also considered in relation to the structures from which they were uncovered. The study revealed that the agricultural economy of both studied periods relied on emmer, barley, lentils, and pea, but from the Early Dynastic times onwards also flax and condiments (like Anethum graveolens and cf. Origanum sp.) played a certain role. Together with the cultivated fields also the surrounding wetlands were an important part of the plant resources utilized at site. The stems of Phragmites are also the most common among the anthracological remains, together with a small proportion of Tamarix and Acacia charcoal fragments. The overall composition of the plant assemblages (charred and mineralised chaff, small weed or wild growing seeds capable to pass the herbivore digestion, dung fragments, awns) suggest that the major source of the retrieved plant remains was dung fuel.

Article Reference Tributyltin: A Bottom–Up Regulator of the Crangon crangon Population?
The restrictions and the concerted action of the global ban on the use and presence of tributyltin (TBT) in marine applications to protect ecosystems in the marine environment in 2008 was mainly based on the economic impact on shellfish industries and the dramatic extinction of local mollusk populations in the past. In contrast to the vast datasets on effects on mollusks, the knowledge on impacts on species from other taxa remained in the uncertain until almost two decades ago. The assumption on a long-term TBT-mediated pernicious metabolic bottom–up regulation of the crustacean Crangon crangon population was provoked by the outcome of an EU-project ‘Sources, Consumer Exposure and Risks of Organotin Contamination in Seafood.’ This study reported high TBT body burdens in C. crangon in 2003, at the start of the transition period to the global ban. Experimental research on the TBT impact in C. crangon focused on agonistic interference with natural ecdysteroid hormones at the metabolic pathways regulating growth and reproduction and the biogeochemical distribution of the chemical. In this paper, metabolic, topical and population-relevant biological endpoints in C. crangon and other crustaceans are evaluated in relation to the temporal and spatial trends on TBT’s occurrence and distribution in the field during and after the introduction of the tributyltin restrictions and endocrine-related incidents. Arguments are forwarded to relate the German Bight incident on growth and reproduction failure in the C. crangon population, despite the lack of direct evidence, to the pernicious impact of tributyltin in 1990/91 and previous years. The extreme occurrence of TBT in C. crangon from other parts of the southern North Sea and evidence on the high body burdens as dose metrics of exposure also feeds the suspicion on detrimental impacts in those areas. This paper further demonstrates the complexity of distinguishing and assessing the individual roles of unrelated stressors on a population in an integrated evaluation at the ecosystem level.

Article Reference On a new species of the genus Cyprinotus (Crustacea, Ostracoda) from a temporary wetland in New Caledonia (Pacific Ocean), with a reappraisal of the genus
The New Caledonia archipelago is known for its high level of endemism in both faunal and floral groups. Thus far, only 12 species of non-marine ostracods have been reported. After three expeditions to the main island of the archipelago (Grande Terre), about four times as many species were found, about half of which are probably new. Here, we describe a new species, Cyprinotus drubea sp. nov., which is characterised mainly by the hyper-developed dorsal hump on the right valve, much larger than in any other known Recent species in this genus. After a literature study of the other presumed species in Cyprinotus Brady, 1886, we retain seven Recent species in the genus, including the present new species. Cyprinotus crenatus (Turner, 1893), C. dentatus (Sharpe, 1910), C. flavescens Brady, 1898, C. inconstans Furtos, 1936, C. newmexicoensis Ferguson, 1967, C. ohanopecoshensis Ferguson, 1966, C. pellucidus (Sharpe, 1897), C. scytodus (Dobbin, 1941) and C. sulphurous Blake, 1931 are here all referred to the genus Heterocypris s. lat. Claus, 1892. Cyprinotus unispinifera Furtos, 1936 is assigned to the genus Cypricercus Sars, 1895. Cyprinotus tenuis Henry, 1923, C. fuscus Henry, 1919 and C. carinatus (King, 1855) are here classified as doubtful species. A checklist of the 14 non-marine ostracods, now including Cyprinotus drubea sp. nov. and Cypris granulata (Daday, 1910), thus far reported from New Caledonia, is provided. Herpetocypris caledonica Méhes, 1939 and H. caledonica var. minor Méhes, 1939 are synonymised with Candonocypris novaezelandiae (Baird, 1843).
