Use of habitat and migratory patterns of large coastal sharks in the argentinian seaAbstract
El objetivo general de esta tesis es la descripción y análisis de los patrones espaciales y temporales en el uso de hábitat de las cuatro especies de grandes tiburones costeros más comunes del Mar Argentino, Galeorhinus galeus (cazón), Notorynchus cepedianus (gatopardo), Carcharhinus brachyurus (bacota) y Carcharias taurus (escalandrún), relacionando estos patrones con su entorno ambiental. Se plantearon dos enfoques, uno a nivel poblacional para determinar la distribución potencial, el patrón migratorio y las asociaciones de hábitat de las especies a gran escala espacial (Atlántico Sudoccidental, ~23-58ºS), y un segundo enfoque a una escala espacio-temporal más pequeña para el estudio específico del uso de hábitat de una de las especies (N. cepedianus) en un área de agregación (Caleta Valdés).The general objective of this thesis is the description and analysis of spatial and temporal patterns in the habitat use of the four most common species of large coastal sharks in the Argentinian Sea, Galeorhinus galeus (school shark), Notorynchus cepedianus (sevengill shark), Carcharhinus brachyurus (copper shark), and Carcharias taurus (sand tiger shark), and the relationship of these patterns with their environmental surroundings. Two approaches were considered: one at the population level to determine potential distribution, migratory patterns, and habitat associations of the species on a large spatial scale (Southwest Atlantic, ~23-58ºS), and a second approach on a smaller spatial-temporal scale to specifically study the habitat use of one of the species (N. cepedianus) in an aggregation area (Caleta Valdés).
