Neomaenas poliozona subsp. eustephanos Matz, stat. nov.
No full textNeomaenas poliozona eustephanos Matz stat. nov., nom. nov. (Figs. 7 F; 26) (objective replacement name for Neomaenas poliozona reedii (Butler, 1881) (Neosatyrus) under ICZN Art. 60.3 (1999)). Holotype: (male) BMNH Type No. Rh 3872 Type Location: Chile Distribution. Found in Chile from the southwestern part of Bío-Bío province to Araucanía province at 50–200m from January to early March (Fig. 26). Though the range of N. poliozona eustephanos is similar to that of N. poliozona poliozona, populations are allopatric. Ecological factors that separate these two subspecies are unknown and in need of further study. Diagnosis. Identical to N. poliozona poliozona, but lacking the black spots on the ventral side of the hindwing, darker in color, and having a ripple pattern in dark chocolate striations over the hindwing. Redescription. Head: Palps with a longitudinal black stripe bordered dorsally with a cream to white stripe. Dorsal side piliform scales on the palps are black and scales on the ventral side are black and tan. Forewing (Fig. 7 F): Dorsal side chocolate to dark chocolate brown, females with a patch of rust orange that extends from the discal cell to subterminal band. Postmedian band appears on the dorsal side of some males as a pair of rectangular patches between M 3 and CuA 2. Apical ocellus between M 1 -M 3 appearing in some specimens as a round black spot. Ventral side similar in color to the dorsal side with a rust orange patch extending from the discal cell to the subterminal band, the postmedian band slightly lighter and bordered in dark chocolate. A ripple pattern with dark chocolate to dark coffee striations that extend along the costa and subterminal band. Hindwing (Fig. 7 F): Dorsal side similar in color to the forewing, postmedian band appearing in rust orange from M 1 to the inner margin in females and rust red to rust orange in patches from M 2 to CuA 1 and from CuA 2 to the inner margin. Postmedian band may not appear in darker specimens. Ventral side dark taupe to warm medium brown with a ripple pattern appearing in dark chocolate to dark coffee over the entire wing. Postmedian band is a saturated lavender, edged on the median side in dark chocolate. Hindwing ocelli rarely appear as small, round, black spots between Rs-M 1, M 1 -M 2, or CuA 1 -CuA 2. Remarks. The taxon bearing the name Neosatyrus reedii Butler, 1881 has been regarded previously as a separate species in a separate genus from N. poliozona poliozona by its original author and by Weymer (1911), and synonymized with N. poliozona by Ureta (1956) and Lamas & Viloria (2004). Herrera (1966) placed reedii in Neomaenas and noted its similarity to poliozona in genitalic features, also but differences in distribution and wing pattern, remarking that it may be a legitimate subspecies of N. poliozona. Our decision to synonymize Spinantenna Hayward, 1953, with Neomaenas Wallengren, 1858, means that Neomaenas reedii (Butler, 1881) (now viewed as a subspecies of N. poliozona) becomes a secondary junior homonym of Neomaenas reedi (Reed, 1877), under Arts. 57.3. 1 and 58.14 of the ICZN Code (ICZN 1999), because the latter is has priority as an available name, even though it is considered a subjective junior synonym of N. tristis (Guerin-Ménéville, [1830]). Etymology. the name refers to the purple submarginal band on the HWV. Specimens examined.

Marine biofilm bacteria evade eukaryotic predation by targeted chemical defense
No full textMany plants and animals are defended from predation or herbivory by inhibitory secondary metabolites, which in the marine environment are very common among sessile organisms. Among bacteria, where there is the greatest metabolic potential, little is known about chemical defenses against bacterivorous consumers. An emerging hypothesis is that sessile bacterial communities organized as biofilms serve as bacterial refuge from predation. By testing growth and survival of two common bacterivorous nanoflagellates, we find evidence that chemically mediated resistance against protozoan predators is common among biofilm populations in a diverse set of marine bacteria. Using bioassay-guided chemical and genetic analysis, we identified one of the most effective antiprotozoal compounds as violacein, an alkaloid that we demonstrate is produced predominately within biofilm cells.Nanomolar concentrations of violacein inhibit protozoan feeding by inducing a conserved eukaryotic cell death program. Such biofilm-specific chemical defenses could contribute to the successful persistence of biofilm bacteria in various environments and provide the ecological and evolutionary context for a number of eukaryote-targeting bacterial metabolites
Augustine, the Carolingians, and Double Predestination
No full textThe contributors to Grace for Grace focus on the debates on grace and free will inspired by Augustine\u27s later teachings on grace ad the various reactions to it. Based on fresh study of a wealth of primary sources, this international team of scholars explores the intra-Church debates over grace and free will after Augustinje and Pelagius. In both popular and scholarly literature, the conflict has been traditionally referred to as the Semi-Pelagian Controversy. For several decades, however, scholars have been distancing themselves from that simplistic and inaccurate portrayal. This book intends to solidify a disparate movement of scholarly thought and provide a secure basis for renewal study of the persons, texts, and events of a critical period in the reception of Augustine in the Early Middle Ages.

Off the hook - how bacteria survive protozoan grazing
No full textBacterial growth and survival in numerous environments are constrained by the action of bacteria-consuming protozoa. Recent findings suggest that bacterial adaptations against protozoan predation might have a significant role in bacterial persistence and diversification. We argue that selective predation has given rise to diverse routes of bacterial defense, including adaptive mechanisms in bacterial biofilms, and has promoted major transitions in bacterial evolution, such as multicellularity and pathogenesis. We propose that studying predation-driven adaptations will provide an exciting frontier for microbial ecology and evolution at the interface of prokaryotes and eukaryotes
