Ictiólogos de la Argentina: María Luisa Fuster de Plaza.

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.

Factors influencing the downstream transport of sediment in the Lough Feeagh catchment, Burrishoole, Co. Mayo, Ireland

Research laboratories in the Burrishoole catchment have been the focus of salmonid research since 1955. One aspect of the research has been to monitor the number of salmon and sea trout migrating to sea as smolts and returning to the catchment as adults. In the early 1990s it became clear that the smolt output from the catchment had declined over the previous two decades. At about the same time the presence of fine particles of peat silt in the hatchery became increasingly apparent and led to a higher incidence of mortality of young fry. These observations and management difficulties led to a study of silt transport in the surface waters of the catchment, which is described in this article. The authors describe geology, soils, climate and hydrology of Burrishoole before examining the sediment deposition in Lough Feeagh.

Modelling soil erosion and transport in the Burrishoole catchment, Newport, Co. Mayo, Ireland

The Burrishoole catchment is situated in County Mayo, on the northwest coast of the Republic of Ireland. Much of the catchment is covered by blanket peat that, in many areas, has become heavily eroded in recent years. This is thought to be due, primarily, to the adverse effects of forestry and agricultural activities in the area. Such activities include ploughing, drainage, the planting and harvesting of trees, and sheep farming, all of which are potentially damaging to such a sensitive landscape if not managed carefully. This article examines the sediment yield and hydrology of the Burrishoole catchment. Flow and sediment concentrations were measured at 8-hourly intervals from 5 February 2001 to 8 November 2001 with an automatic sampler and separate flow gauge, and hourly averages were recorded between 4 July 2002 and 6 September 2002 using an automatic river monitoring system [ARMS]. The authors describe the GIS-based model of soil erosion and transport that was applied to the Burrishoole catchment during this study. The results of these analyses were compared, in a qualitative manner, with the aerial photography available for the Burrishoole catchment to see whether areas that were predicted to contribute large proportions of eroded material to the drainage network corresponded with areas where peat erosion could be identified through photo-interpretation.

Semblanzas Ictiológicas: María Laura Habegger

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.

Ictiólogos de la Argentina: María de los Ángeles Bistoni.

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.

Dibujantes de la Facultad de Ciencias Naturales y Museo: María Cristina Estivariz.

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.
