description |
Studies on decapod distribution patterns and reproductive and energetic conditions were carried out along the islands and shallows of the Scotia Arc (Southern Ocean) during the RV “Polarstern” LAMPOS expedition (ANT XIX/5) between April and May 2002. A clear biogeographic zonation was found. The Subantarctic Magellan-South Atlantic decapod fauna consisting of both “natant” (caridean) and “reptant” (astacidean, anomuran, and brachyuran) decapods appeared along the northern branch of the Scotia Arc to South Georgia, where Subantarctic and Antarctic faunas were found overlapping. An impoverished caridean shrimp fauna was found along the islands of the southern branch, from the South Sandwich Islands to the Antarctic Peninsula. Differences in the reproductive traits of the two most abundant species were detected. The reproductive cycle of Notocrangon antarcticus at South Georgia was more advanced than that at the South Orkney Islands, probably due to temperature differences between the two locations. Although the oogenesis and the reproductive cycle of Munida subrugosa seem to be in phase at Burdwood Bank and in the Beagle Channel, the oocyte number is probably lower at the former location. A new index was used to measure the energy devoted to reproduction by relating the energy contents of the egg mass/ovary plus hepatopancreas and the energy content of the whole body. This index revealed that the energy investment in reproduction was (1) independent of the sampling location, (2) species-specific, and (3) larger in caridean shrimps than in galatheid crabs. En abril y mayo de 2002, durante la expedición LAMPOS (ANT XIX/5) a bordo del BIO “Polarstern” se realizaron estudios sobre la distribución y condiciones reproductivas y energéticas en aguas someras del Arco de Scotia (Océano Austral). Se encontró una clara zonación biogeográfica: sobre la rama septentrional del Arco de Scotia hasta las Islas Georgias del Sur prevalece fauna de decápodos subantárticos –de la Provincia Magallanica y del Atlántico Sur– constituida por “Natantia” (carideos) y “Reptantia” (astacideos, anomuros y braquiuros). En las Islas Georgias del Sur las faunas subantárticas y antárticas se superponen. En la rama meridional, desde las Islas Sandwich del Sur hasta la Península Antártica, se encontró una fauna limitada a los camarones. Se hallaron diferencias en aspectos reproductivos de dos de las especies más abundantes. El ciclo reproductivo de Notocrangon antarcticus en las Islas Georgias del Sur estaba avanzado en comparación con el de la población de las Islas Orcadas del Sur, probablemente debido a la diferencia de temperaturas entre ambas localidades. A pesar que la oogenesis y el ciclo reproductivo de Munida subrugosa parecieran estar en fase en el Banco Burdwood y en el Canal Beagle, el número de oocitos es probablemente menor en la primera localidad. Se utilizó un nuevo índice que relaciona el contenido energético entre la masa de huevos/ovario más el hepatopancreas y el contenido energético del animal completo. Este índice reveló que la inversión energética en reproducción fue (1) independiente de la localidad, (2) especie-específica y (3) más alta en camarones que en cangrejos galateidos. |
