“…Studies on the diversity, distribution, and abundance of Appendicularia in the Southern Ocean are very sparse and are limited to the genus or family levels, probably due to the fragility of appendicularians and the selectivity of the nets used [12,13]. A recent study conducted by some authors [14] noted a significant occurrence of appendicularians in the seasonal ice zone (SIZ) in the Southern Ocean.…”

Appendicularians are one of the most common animals found within zooplankton assemblages. They play a very important role as filter feeders but are, unfortunately, inconsistently reported in the Antarctic literature. The present paper attempts to describe the zonal diversity of appendicularians and the main environmental factors influencing their communities in the Drake Passage. Samples were collected during Antarctic summer in 2009–2010. A total of eight species of larvaceans were identified. Fritillaria borealis was the species found in the highest numbers in almost the entire studied area, and was observed at all sampling stations. The distributions of other taxa were limited to specific hydrological zones and hydrological conditions. F. fraudax and Oikopleura gaussica were typical of the areas between the Polar Front and the Subantarctic Front zones, and their distributions were significantly correlated with temperature and salinity, likely making them good indicator species. The F. fusiformis distribution was strictly related to South American waters. In summary, temperature was the strongest environmental factor influencing the larvacean community structure in the Drake Passage, and we also found that testing environmental factors on larvaceans as a whole group did not give entirely reliable results.

“…Previously, Capitanio et al [15] analyzed the variability in the characteristics that define the Oikopleura gaussica group in Antarctic waters. Furthermore, published data on appendicularians mainly concerned their role and importance in the Southern Ocean zooplankton community structure in general [13,14,[16][17][18][19].…”
