Abstract The Southern Ocean is one of the most isolated marine ecosystems, characterized by high levels of endemism, diversity, and biomass. Ascidians are among the dominant groups in Antarctic benthic assemblages; thus, recording the evolutionary pa

Extended glacier retreat is among the main consequences of the rapid warming of the West Antarctic Peninsula. Particularly, in the inner part of Potter Cove (South Shetland Islands, Antarctica) large areas are now exposed to open sea conditions owing

Reproductive biology of the Antarctic 'sea pen' Malacobelemnon daytoni (Octocorallia, Pennatulacea, Kophobelemnidae)

Autor: Ricardo Sahade, Natalia Servetto, Luciana Torre

Publikováno v: Polar Research, Vol 32, Iss 0, Pp 1-11 (2013)

The reproductive biology of the sea pen Malacobelemnon daytoni was studied at Potter Cove, South Shetland Islands, where it is one of the dominant species in shallow waters. Specimens collected at 15–22 m depth were examined by histological analysi

Ocean acidification (OA) could become a serious threat for theAntarctic marine ecosystem over coming years, as the solubility of atmosphericCO2 and CaCO3 minerals increases at lower temperatures.We evaluated the effect of OA on the stress response of
