Journal ArticleDOI
No longer the pristine confines of the world ocean: a survey of exotic marine species in the southwestern Atlantic
Jose Maria,Evangelina Schwindt,Guido Pastorino,Alejandro Bortolus,Graciela Noemi Casas,Gustavo Darrigran,Sandra Obenat,Marcela Pascual,Pablo E. Penchaszadeh,Fabrizio Scarabino,Eduardo D. Spivak,Eduardo Alberto Vallarino +11 more
TL;DR: A comprehensive survey of existing knowledge about exotic marine organisms introduced to the southwestern Atlantic Ocean, including coastal and shelf areas of Uruguay and Argentina, presents a comprehensive picture of recorded introductions and some prominent ecological consequences.
Journal ArticleDOI
Life cycle and population structure of the polychaete Ficopomatus enigmaticus (Serpulidae) in Mar Chiquita coastal lagoon, Argentina
Sandra Obenat,Silvia E. Pezzani +1 more
TL;DR: Ficopomatus enigmaticus, a polychaete inhabiting the subtidal zone in the Mar Chiquita coastal lagoon, builds reef-like aggregates that facilitate silt accumulation and has two oocyte generations per year; maturation of the oocytes takes approximately 4 mo.
Journal ArticleDOI
Macrobenthos and multi-molecular markers as indicators of environmental contamination in a South American port (Mar del Plata, Southwest Atlantic).
Mariano J. Albano,Paulo da Cunha Lana,Claudia Silvia Bremec,Rodolfo Elías,César C. Martins,Natalia Venturini,Pablo Muniz,Silvia Rivero,Eduardo Alberto Vallarino,Sandra Obenat +9 more
TL;DR: Benthic habitat quality along a presumed contamination gradient in the Mar del Plata port was evaluated by coupling biological and chemical proxies in a multidisciplinary approach and high concentrations of coprostanol in the inner sites seemed to derive from a permanent population of sea lions rather than from sewage outfalls.
Journal ArticleDOI
Life history and reproductive biology of the invasive amphipod Melita palmata (Amphipoda: Melitidae) in the Mar Chiquita coastal lagoon, Argentina
TL;DR: The life history and reproductive biology of the gammaridean amphipod Melita palmata was studied in the Mar Chiquita coastal lagoon (Argentina) and there was a positive correlation between the brood size and body length of ovigerous females, and the maximum number of eggs per female was ten.
Journal ArticleDOI
Assemblage of benthic macrofauna in the aggregates of the tubiculous worm Phyllochaetopterus socialis in the Mar del Plata harbour, Argentina
Mariano J. Albano,Sandra Obenat +1 more
TL;DR: The assemblage of benthic macrofauna with permanent and temporary organisms in P. socialis aggregates suggests the existence of microhabitats in the mats that provide substrate, refuges for predation and availability of food increasing richness and diversity.
