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 Dietary reconstruction of Spy I using dental microwear texture analysis
Spy I from the Meuse River Basin of Belgium is among the most recent Neandertals. This adult lived at the terminus of Marine Isotope Stage (MIS) 3 in cold steppe environments at the northern edge of the habitable zone for Neandertals where plants were relatively scarce. The dietary proclivities of Spy I are reconstructed using dental microwear texture analysis and compared to 33 Neandertals from western Eurasia, MIS 5 to MIS 3. Spy I has an elevated enamel surface complexity suggesting the consumption of course dietary items such as wild seeds, acorns, nuts, and underground storage organs laden with particles of grit. Unlike the young and old individuals from Hortus with low values for anisotropy, Spy I is closest to the adults from this site suggesting a common pattern of masticatory behavior typified this life cycle stage. Like many other Neandertals, Spy I probably consumed plant foods at appreciable levels, some of which were hard and brittle or poorly processed.

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.

Article Reference Differentiation between two salt marsh beetle ecotypes: Evidence for ongoing speciation
The plausibility of trait divergence under divergent natural selection in the presence of gene flow in natural populations is a contentious issue in evolutionary research. Its importance lies in the fact that this process is thought to be one of the key triggers in ecological speciation in which a species splits into ecologically distinct forms when separate niches are occupied. in this study we demonstrate strong genetic divergence at the IDH1 locus between pond- and canal-inhabiting individuals of the salt marsh beetle Pogonus chalceus from the Guerande salt fields. Moreover, wing size, a trait that has a heritable basis in this species, was significantly larger in the pond populations, which is in concordance with the unstable nature of this habitat. The relationship between IDH1 allele frequencies and wing size variation was consistent with patterns seen across western European populations. By means of neutral allozymes and microsatellites we detected a small but significant degree of sexual isolation between ecotypes. We conclude that speciation is ongoing and that divergence reflects a balance between selection and gene flow.
