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.

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.

Digital restoration of the snout of Khirtharia inflata (Raoellidae, Artiodactyla) from the middle Eocene of northwest Himalaya
-
In this work, we digitally restore the snout of the raoellid Khirtharia inflata from the Kalakot area (Rajouri District, Jammu & Kashmir, India). Raoellids are small, semiaquatic ungulates closely related to cetaceans. The specimen is fairly complete and preserves left and right maxillae, left premaxilla, and part of the anterior and jugal dentition. The digital restoration of this quite complete but deformed specimen of Khirtharia inflata is a welcome addition to the data available for raoellids and will be used to further the understanding of the origins of cetaceans.

Dispersal model alert on the risks of alien species introduction by ballast waters in protected areas from the Western Antarctic Peninsula
-
Aim The Western Antarctic Peninsula is challenged by climate change and increasing maritime traffic that together facilitate the introduction of marine non-native species from warmer regions neighbouring the Southern Ocean. Ballast water exchange has been frequently reported as an introduction vector. This study uses a Lagrangian approach to model the passive drift of virtual propagules departing from Ballast water hypothetic exchange zones, at contrasting distances from the coasts. Location Western Antarctic Peninsula. Methods Virtual propagules were released over the 2008–2016 period and at three distances from the nearest coasts: 200 (convention for the management of Ballast Water, 2004), 50 or 11 nautical miles (NM). Results Results show that exchanging Ballast water at 200 NM considerably reduces the arrival of propagules in proposed marine protected areas of the western side of the Antarctic Peninsula. On the eastern side, propagules can reach north-eastern marine protected areas within a few days due to strong currents for all tested scenarios. Seasonal and yearly variations indicate that exceptional climate events could influence the trajectory of particles in the region. Ballast water should be exchanged at least 200 NM offshore on the western side of the Antarctic Peninsula and avoided on the eastern side to limit particle arrival in proposed marine protected areas. Focusing on Deception Island, our results suggested that the Patagonian crab (Halicarcinus planatus) observed in 2010 could have been introduced in case of Ballast water exchange at 50 NM or less from the coast. Main conclusions This study highlights the importance of respecting Ballast water exchange convention to limit the risk of non-native species introduction. Ballast water exchange should be operated at least at 200 NM from the coasts, which further limits particle arrival in shallow water areas. This is especially important in the context of a more visited and warmer Southern Ocean.
