Spatial distribution of subtidal macrozoobenthos from San Jose Gulf (Chubut, Argentine)

Mostrar todas las versiones(2)

The subtidal macrozoobenthos associations of the San Jose Gulf (42° 20′ S y 64° 20′ W) and their relationship with depth and substrata were studied. During the San Jose I survey (September-October 1984), 120 grab sample units were taken, with 231 species of molluscs, polychaets, crustaceans, echinod...

The zoogeographic characteristics of the San Jose Gulf macrozoobenthos are discussed and comparisons among found groups with other similar assemblages are performed.
