Article Reference Didelphodus caloris, new species (Mammalia, Cimolesta), from the Wasatchian Wa-0 fauna of the Paleocene-Eocene Thermal Maximum, Clarks Fork Basin, Wyoming
The Wasatchian Wa-0 mammalian fauna from the Paleocene-Eocene Thermal Maximum (earliest Eocene) is reasonably well sampled in North America, but mammals of small body size are still poorly known. Here we describe a new species of the insectivore Didelphodus based on a cranial rostrum, both dentaries, and a nearly complete upper and lower dentition, all found by screen-washing. The new species, D. caloris, is the oldest species of the genus known in North America. It differs from later early Eocene Didelphodus in being substantially smaller, in having relatively simple premolars, and in having a more reduced M3 relative to preceding molars. Precursors of Didelphodus are not known with certainty, and the species D. caloris may be an immigrant to mid-continent North America. D. caloris is tentatively interpreted as a dwarfed form like other Wa-0 mammals because of its small size relative to the better-known successor species D. absarokae.

Article Reference Diet Records for Snakes from Guinea, West Africa
We present various predation records based on museum-preserved snakes from southeastern Republic of Guinea, West Africa: Aparallactus niger (Atractaspididae) on an earthworm (Oligochaeta); Crotaphopeltis hotamboeia (Colubridae) on Sclerophrys sp. (Anura; Bufonidae); Grayia smithii (Colubridae) and Natriciteres variegata (Natricidae) on Arthroleptis sp(p). (Anura; Arthroleptidae); Grayia tholloni on Xenopus cf. tropicalis (Anura; Pipidae); Toxicodryas pulverulenta (Colubridae) on Agama cf. sankaranica (Agamidae); Elapsoidea semiannulata moebiusi (Elapidae) on Hemisus cf. guineensis (Anura; Hemisotidae); Naja savannula (Elapidae), Afronatrix anoscopus (Natricidae) and Causus maculatus (Viperidae) on Sclerophrys regularis; Psammophis phillipsii (Psammophiidae) on Trachylepis cf. affinis (Scincidae); Causus maculatus on Ptychadena sp. (Anura; Ptychadenidae); Limaformosa guirali (Lamprophiidae) on Atheris chlorechis (Viperidae); and Atheris chlorechis on Hyperolius sp. (Anura; Hyperoliidae). Diagnostic morphological characters are provided for all snakes involved in these records, as well as clutch sizes for pregnant females (Crotaphopeltis hotamboeia and Causus maculatus). We provide identifications for some insects found in the stomachs of the ingested amphibians.

Article Reference Diet, hygiene and health in Roman period northern Gaul: A multidisciplinary study of a latrine from an artisan household in the vicus Orolaunum (Arlon, southern Belgium, c. 250–280 CE)
Botanical (macro remains and pollen) and animal remains, including intestinal parasites, from a latrine dated between c. 250 CE and 280 CE from the artisan quarter of the vicus Orolaunum (Arlon) have been studied. The results provide information on the diet and health of a non-elite and poorly understood part of the population in northern Gaul. The identified plant remains document a diet which include several Roman introductions to the region, but hardly any truly exotic imports. Also the remains of fish sauce have been identified, but this was a locally produced variety and possibly a cheaper version of the typical Mediterranean product. The results indicate that the diet of the household using the latrine was strongly influenced by romanisation and that the lack of exotic imports was most likely the result of a low economic status rather than a lack of interest for these products. The people using the latrine were also infected with both roundworm and whipworm, two intestinal parasites that were probably common in the population of northern Roman Gaul and which are spread when sanitation is ineffective.

Article Reference Differences in geographic distribution and habitat of some cryptic species in the Pardosa lugubris group (Lycosidae, Araneae) in Belgium
The habitat and distribution of some closely related species of the P. lugubris s.l. group in Belgium are described to contribute to our understanding of the coexistence and speciation of these 'cryptic' species. With a few exceptions, P. lugubris has its main distribution in the lower part of Belgium where it occurs on sandy, nutrient poor soils. P. saltans occurs widely in Belgium except for in the Campine region where the species is totally absent. P. alacris was only found at three localities where limestone outcrops are present. The habitat of P. lugubris is pine and birch forests while in Fagus woodlands, only P. saltans was found. In Quercus forests, both species were found, often in mixed populations. A combination of micro- and macroclimatological features and habitat characteristics cause the differences in distribution of these species.
