Mycale (Aegogropila) magellanica (Porifera: Demospongiae) in the southwestern Atlantic Ocean: endobiotic fauna and new distributional information
The composition of endobionts in the sponge Mycale (Aegogropila) magellanica at the shelf-break, near 100 m depth, in the Argentine Sea was studied. We also provide new information on the distribution of M. (A.) magellanica, extending its northern limit to 38º36.02’S and 55º44.68’W, 91 m in the SW A...

description |
The composition of endobionts in the sponge Mycale (Aegogropila) magellanica at the shelf-break, near 100 m depth, in the Argentine Sea was studied. We also provide new information on the distribution of M. (A.) magellanica, extending its northern limit to 38º36.02’S and 55º44.68’W, 91 m in the SW Atlantic Ocean. The main Patagonian scallop fishing grounds are located in the shelf-break frontal area of the Argentine Sea. In this area, M. (A.) magellanica plays an important role in providing habitat for at least 23 taxa of small invertebrates, mostly crustaceans (66% to 96% of the total number of individuals). On average, this sponge hosted 348 individuals per litre; Aristias cf. antarcticus (Amphipoda) was the most frequent and abundant species. Other organisms commonly found were the isopod Caecognathia sp., the amphipod Leucothoe cf. spinicarpa, the bivalve Hiatella meridionalis and the ophiuroid Ophiactis asperula. As previously demonstrated for other sponges, our study suggests that M. (A.) magellanica enhances benthic biodiversity, as it shelters a variety of invertebrate species. In areas of soft and flat substrate, erect and sessile epifauna usually acts as an ecosystem engineer, structuring the architecture of the habitat by increasing the sea-bottom complexity. Mass removal of this fauna due to intense trawling activities on Patagonian scallop beds could have devastating effects on local biodiversity. Se estudió la composición de endobiontes de la esponja Mycale (Aegogropila) magellanica, recolectada en el área del talud del Mar Argentino, a una profundidad promedio de 100 m. Se presenta también nueva información sobre la distribución de M. (A.) magellanica, extendiendo su límite norte hasta los 38º36.02’S y 55º44.68’W, 91 m en el Atlántico Sudoccidental. En el Mar Argentino, los principales bancos de vieira patagónica están situados en el borde externo de la plataforma, en el área frontal del talud. En esta región, M. (A.) magellanica juega un papel importante al proveer hábitat para al menos 23 taxones de invertebrados pequeños, en su mayoría crustáceos (66 al 96% del total de individuos). En promedio, esta esponja alberga 348 individuos por litro de esponja, siendo Aristias cf. antarcticus (Amphipoda) la especie más frecuente y abundante. Otros organismos hallados con frecuencia fueron el isópodo Caecognathia sp., el anfípodo Leucothoe cf. spinicarpa, el bivalvo Hiatella meridionalis y la ofiura Ophiactis asperula. Tal como se ha encontrado en otras esponjas, nuestros resultados sugieren que M. (A.) magellanica enriquece la biodiversidad local al proveer refugio a una gran variedad de invertebrados bentónicos. En áreas de sustrato blando, la epifauna eréctil y sésil estructura la arquitectura del hábitat, aumentando la complejidad del fondo. La extracción de esta fauna a causa de una intensa actividad pesquera en los bancos de la vieira patagónica tendría efectos perjudiciales sobre la biodiversidad local. |

We also provide new information on the distribution of M. (A.) magellanica, extending its northern limit to 38º36.02’S and 55º44.68’W, 91 m in the SW Atlantic Ocean. The main Patagonian scallop fishing grounds are located in the shelf-break frontal area of the Argentine Sea. In this area, M. (A.) magellanica plays an important role in providing habitat for at least 23 taxa of small invertebrates, mostly crustaceans (66% to 96% of the total number of individuals). On average, this sponge hosted 348 individuals per litre; Aristias cf. antarcticus (Amphipoda) was the most frequent and abundant species. Other organisms commonly found were the isopod Caecognathia sp., the amphipod Leucothoe cf. spinicarpa, the bivalve Hiatella meridionalis and the ophiuroid Ophiactis asperula. As previously demonstrated for other sponges, our study suggests that M. (A.) magellanica enhances benthic biodiversity, as it shelters a variety of invertebrate species. In areas of soft and flat substrate, erect and sessile epifauna usually acts as an ecosystem engineer, structuring the architecture of the habitat by increasing the sea-bottom complexity. Mass removal of this fauna due to intense trawling activities on Patagonian scallop beds could have devastating effects on local biodiversity. Se estudió la composición de endobiontes de la esponja Mycale (Aegogropila) magellanica, recolectada en el área del talud del Mar Argentino, a una profundidad promedio de 100 m. Se presenta también nueva información sobre la distribución de M. (A.) magellanica, extendiendo su límite norte hasta los 38º36.02’S y 55º44.68’W, 91 m en el Atlántico Sudoccidental. En el Mar Argentino, los principales bancos de vieira patagónica están situados en el borde externo de la plataforma, en el área frontal del talud. En esta región, M. (A.) magellanica juega un papel importante al proveer hábitat para al menos 23 taxones de invertebrados pequeños, en su mayoría crustáceos (66 al 96% del total de individuos). En promedio, esta esponja alberga 348 individuos por litro de esponja, siendo Aristias cf. antarcticus (Amphipoda) la especie más frecuente y abundante. Otros organismos hallados con frecuencia fueron el isópodo Caecognathia sp., el anfípodo Leucothoe cf. spinicarpa, el bivalvo Hiatella meridionalis y la ofiura Ophiactis asperula. Tal como se ha encontrado en otras esponjas, nuestros resultados sugieren que M. (A.) magellanica enriquece la biodiversidad local al proveer refugio a una gran variedad de invertebrados bentónicos. En áreas de sustrato blando, la epifauna eréctil y sésil estructura la arquitectura del hábitat, aumentando la complejidad del fondo. La extracción de esta fauna a causa de una intensa actividad pesquera en los bancos de la vieira patagónica tendría efectos perjudiciales sobre la biodiversidad local.
