Abstract
Eleginops maclovinus (Valenciennes, 1830) es un pez comun en el litoral, estuarios y tambien rios, preferentemente donde afectan las mareas, del sur de America del Sur, incluyendo las islas Malvinas. Se conoce su alimentacion en los dos primeros habitats, donde consume principalmente animales de ambiente marino y estuarino, donde se alimenta de fauna autoctona (mejillones, crustaceos, poliquetos, etc.). Sin embargo, se desconoce su alimentacion en ambientes limneticos, suponiendose que deberia consumir presas propias de aquellos lugares. En este estudio se analizaron 114 ejemplares de E. maclovinus, de los cuales 98 poseyeron estomagos con contenido. Se ratifico la tendencia zoofagica de la especie, pero tambien se comprobo que en ambientes limneticos consume animales propios de bajas salinidades o salinidades limneticas. El pez se presenta como una especie extraordinariamente versatil en sus capacidades troficas, con una fisiologia que le permite cubrir un amplio abanico ormorregulatorio a nivel digestivo, probablemente uno de las mas variados en el suborden Notothenioidei, de supuesto origen antartico.
期刊介绍:
Interciencia is the monthly multidisciplinary publication of the INTERCIENCIA Association. It is dedicated to stimulate scientific research, its humanitarian use and the study of its social context, specially in Latin America and the Caribbean and to promote communication between the scientific and technological communities of the Americas.
Interciencia has been published uninterruptedly since 1976. Its Founding Director, Marcel Roche (endocrinologist and sociologist of science) was editor until 2008, and thereafter Miguel Laufer (neurobiologist) has been in charge. It has been included since 1978 in the Science Citation Index and other international indexes, and since 2008 it maintains an open access electronic version with material from 2005 onwards.
The priority areas of the journal, without exclusion of other areas, are Agronomy, Arid Lands, Food and Nutrition, Biotechnology, Ecology and Environment, Energy, Innovation and Technology Transfer, Marine Resources, Non-renewable Resources, Science Education, Science Policy, Study and Sociology of Science, and Tropical Forests.
Interciencia publishes in Spanish, Portuguese and English research and review articles, communications and essays, all of which are subjected to peer review. Additionally, it includes non-refereed sections such as Editorial, Letters to the Editor, Open Town Hall, Book Reviews and Upcoming Events.
All the material submitted to the journal for publication and accepted by the Editorial Committee in view of its quality and pertinence is subjected to review by peer specialists in the corresponding fields of knowledge.
