This series will include all those people who, by means of their contributions, great and small, played a part in the consolidation of ichthyology in Argentina. The general plan of this work consists of individual factsheets containing a list of works by each author, along with reference bibliography and, whenever possible, personal pictures and additional material. The datasheets will be published primarily in chronological order, although this is subject to change by the availability of materials for successive editions. This work represents another approach for the recovery and revalorization of those who set the foundations of Argentine ichthyology while in diverse historical circumstances. I expect this to be the beginning of a major work that achieves the description of such a significant part of the history of natural sciences in Argentina.

[EN] What is Braulio asking from Eugenius in this passage: that he requires a Mass to be celebrated (where?) in honour of San Millán, or that Eugenius himself writes the Mass, or, simply, some parts or prayers for it? Firstly, translations and interpretations provided by scholars to date are checked and criticized; then an interpretation of the passage is proposed, being based on textual criticism approaches, on the work context and on the cultural environment in which this work takes place.

[ES] La iglesia de Santa María tiene una planta de unos 22x18 metros y cuenta con tres pórticos (sur, oeste y norte) así como una espadaña exenta. Adyacente al sudeste se encuentra la ermita de Santa Lucía. Las excavaciones arqueológicas de dos zonas de unos 6 x 3 metros en el interior y el exterior de la iglesia sirven como hilo conductor a las jornadas de puertas abiertas al público.

A través de esta serie intentaremos conocer diferentes facetas personales de los integrantes de nuestra “comunidad”. El cuestionario, además de su principal objetivo, con sus respuestas quizás nos ayude a encontrar entre nosotros puntos en común que vayan más allá de nuestros temas de trabajo y sea un aporte a futuros estudios históricos. Esperamos que esta iniciativa pueda ser otro nexo entre los ictiólogos de la región, ya que consideramos que el resultado general trascendería nuestras fronteras.

En esta serie se mencionan a todos aquellos que, a través de sus pequeños o grandes aportes, contribuyeron a la consolidación de la disciplina en nuestro país. El plan general de esta contribución consiste en la elaboración de fichas individuales que contengan una lista de trabajos de los diferentes autores, acompañadas por bibliografía de referencia y, cuando ello fuera posible, por imágenes personales y material adicional. Se tratará de guardar un orden cronológico, pero esto no es excluyente, ya que priorizaremos las sucesivas ediciones al material disponible. Este es otro camino para rescatar y revalorizar a quienes en diversos contextos históricos sentaron las bases de lo que hoy es la ictiología nacional. Considero que este es el comienzo de una obra de mayor magnitud en la que se logre describir una parte importante de la historia de las ciencias naturales de la República Argentina.

En este número de la Serie Documentos presentamos a María Cristina Estivariz, ilustradora científica que extendió su labor a otras manifestaciones plásticas. Durante su paso como estudiante de la Facultad de Ciencias Naturales y Museo de La Plata, ingresa al CONICET a la carrera CPA bajo la dirección del Dr. Ricardo Ronderos y posteriormente se incorpora al CEPAVE, donde crea el Laboratorio de Ilustración Científica.. Entre sus actividades, realizó numerosas ilustraciones de Trabajos científicos, tesis doctorales, ilustraciones de trabajos inéditos, comunicaciones a congresos, simposios reuniones científicas, libros algunos de ellos sobre la enseñanza de la ilustración científica. Exposiciones como organizadora e integrante en el marco de congresos de biología museos y galerías. Realizo maquetas y dioramas para diferentes salas del Museo de Ciencias Naturales de La Plata, y sellos postales para el Correo Argentino. Desarrolló una labor artística como miniaturista en biología. En 1985 crea el curso de Introducción a la Ilustración Científica, pasantías de formación y actividades de extensión sobre Ilustración Científica. Este archivo, además de revelar las dotes de ilustradora científica y plásticas de la Sra. Estivariz, muestra que el Museo de La Plata es un generador, no sólo del conocimiento, sino también del virtuosismo de sus integrantes.

The black scabbardfish is a deep water species that supports commercial fisheries across a large area of the NE Atlantic shelf. The life history of black scabbardfish is poorly understood and a major unresolved issue is population structure. In this study it was used a combination of methodologies to get further knowledge in the life history and population structure of A. carbo over its wide distribution range in the Northeast Atlantic. The new knowledge acquired during this study, will increase our ability to better manage this species in the NE Atlantic. It has been postulated that fish caught to the west of the British Isles are pre-adults that migrate further south (to Madeira) for spawning, implying a single panmictic population. In this study, specimens of Aphanopus carbo were sampled between September 2008 and May 2010 from two different areas: NW Scotland (French trawlers and deep water surveys) and Madeira Islands (longliners commercial landings). Geographical differences in reproductive state of scabbardfish were evident, supportive of a north-south migration theory. In the northern area, all specimens found were immature, while in Madeira all maturity stages were observed. In Madeira, spawning occurred during the fourth quarter, with peak maturity in October (males) and in November (females). The age of this species has proven difficult and has led to different and contradictory age and growth estimates. For this study, we used two reading interpretations to determine age and estimate the growth parameters. To the west of the British Isles, specimens reached a lower maximum age and had a higher growth rate than those caught off Madeira. These differences are consistent with the theory of a single population of black scabbardfish in the NE Atlantic, highly segregate, with smaller, immature and younger fish caught to the west of the British Isles and bigger and mature caught in Madeira Islands. The feeding ecology showed strong evidence that the diet of black scabbardfish is associated with the spawning migration of blue whiting, which may support a northerly feeding migration theory for black scabbardfish. The stable isotope analyses in the muscle of black scabbardfish identified that black scabbardfish feeds on species with epipelagic and benthopelagic affinities. Comparison with stable isotope analysis in Madeira samples indicated that black scabbardfish feed at a similar trophic level and has the same trophic niche width in both areas, assuming similar baseline isotope compositions. Otolith stable isotopes (oxygen - δ18O and nitrogen - δ15N) analyses were used as a tool to clarify migratory behaviour. Otolith isotope ratios can provide insight into whether adults caught around Madeira fed in an isotopically depleted northerly ecosystem (NW Scotland) during their pre-adult period and then migrate towards south to spawn. Overall, the results support a south-north migration of pre adult fish from spawning areas around Madeira and a north-south migration from the west of Scotland to the spawning areas. Given its life cycle there is an urgent need that the management process recognizes the existence of a continuous widely distributed stock of black scabbardfish between the west of the British Isles and Madeira. The results highlight large scale dispersal in this species which needs to be treated as a highly migratory species and be managed as a single population.
