Contribution to the knowledge of living representatives of the genus Lutreolina Thomas, 1910 (Mammalia, Marsupialia, Didelphidae)

Se describe una nueva especie extinta del género Lutreolina Thomas, 1910 (Didelphidae, Didelphini). Lutreolina materdei sp. nov., del Mioceno tardío (Edad Huayqueriense) de la Amazonia peruana, se diferencia de las otras especies del género por su mayor tamaño y la presencia de molares inferiores con la paracrístida y la entocrístida más desarrolladas, la cresta posterolingual al metacónido (post-metacrístida) más grande, el hipoconúlido más reducido, la postprotocrístida formando un plano oblicuo con el talónido y el cíngulo anterobasal más estrecho. Asimismo, se describen un resto de basicráneo y un fragmento de dentario, referibles a Lutreolina sp., procedentes de niveles del Pleistoceno temprano del sudeste bonaerense. Los restos pertenecen a una forma robusta, posiblemente representativa de una nueva especie, si bien la imposibilidad de confrontarlos con los de otras especies del género impide el establecimiento de una nueva entidad específica.We describe a new species of the genus Lutreolina Thomas, 1910 (Didelphidae, Didelphini). Lutreolina materdei sp. nov., from the late Miocene (Huayquerian Age) of the Peruvian Amazonia differs from other species of the genus because of its larger size and lower molars with larger paracristid and entocristid; a conspicuous ridge posterolingual to the metaconid (post-metacristid); reduced hypoconulid, and posterior wall of the trigonid descending obliquely towards the talonid. We also describe new remains of Lutreolina sp. from Pleistocene levels of southeastern Buenos Aires Province. Both specimens are referable to a robust, possibly new species of the genus. However, the lack of highly diagnostic remains prevents its specific assignation.Fil: Goin, Francisco Javier. Universidad Nacional de La Plata. Facultad de Ciencias Naturales y Museo.

A new ELISA for the three-spined stickleback (Gasterosteus aculeatus L.) spiggin, using antibodies against synthetic peptide

International audienceThe aim of this study was to develop an enzyme-linked immunosorbent (ELISA) assay to quantify spiggin in the three-spined stickleback. Spiggin is a glue protein produced in the kidney of male three-spined stickleback under the control of androgens during the breeding period. Disturbances of spiggin production in male fish and abnormal induction of spiggin in female fish are considered as valuable biomarkers of exposure to (anti-)androgenic chemicals. Polyclonal antibodies against a peptide sequence of spiggin (HRD-16) were used and the specificity of the antibodies was verified by Western blotting and direct ELISA experiments. By using HRD-16 antibodies and spiggin standard preparation, a competitive ELISA was set-up and validated. This assay appears sensitive, with a detection limit of 0.5 U/mL, and specific, as shown by the competition curves, obtained by serial dilution of male and female kidney homogenates, that were parallel to the spiggin standard curves. The ability of the spiggin ELISA to quantify spiggin induction was achieved by exposing male and female three-spined sticklebacks to 0.1 and 1 micro g/L of methyltestosterone. The results show a significant dose-dependent induction of spiggin in methyltestosterone-exposed female fish compared to controls

Exemplarist Virtue Ethics

In his Nicomachean Ethics, Aristotle introduces the concept of virtue, states of character that allow an agent to perform her function well, and gives a practical account of how someone can become virtuous. I will argue that Aristotle manages to be vague with respect to two epistemic questions: First, how can we identify virtuous people? Second, how can we know which states of character are virtuous? Recently, Linda Zagzebski has introduced a moral theory called exemplarism, which answers that we may identify virtuous people via the emotion of admiration, and that by studying virtuous people, we may come to know which states of character are virtuous. But, Zagzebski’s exemplarism is unmediated; there is no difference between a moral concept and what an exemplar would do or feel in certain circumstances. Problematically, on this account it appears that the more moral experience we have, the murkier our moral concepts become. In what follows, I propose what I call a mediated exemplarism, an account that answers our questions about virtue in the same way as Zagzebski, but on which an exemplar’s actions or feelings do not constitute moral concepts. Rather, on my account, exemplars serve the pedagogical purpose of indicating virtues to an agent, who may then construct a theory of virtue from which moral concepts may be inferred that are divorced from the actions and feelings of a particular exemplar
