چکیده
As a result of processing materials from the expeditions Saint-Petersburg State University in 2012–2013 and Transarctic expedition 2019, 131 polychaete taxa were recorded, which 124 identified to species. On basis data previous recent collections, general list polychaetes Kara Sea was updated; it includes 209 species belonging 98 genera, 37 families, 15 orders. The following are reported for first time sea: Abyssoninoe hibernica (McIntosh, 1903), Ampharete falcata Eliason, 1955, Brada rugosa Hansen, 1882, Microclymene acirrata Arwidsson, 1906; Nephtys pente Rainer, 1984; Ophelina abranchiata Stop-Bowitz, 1948, Scolelepis burkovskii Sikorski, 1994, Travisia forbesii Johnson, 1840. Polychaetes found at all stations; number per station ranged 1 28. Shannon’s indices (H'SpA H'spB) showed that most stations diversity high resistance stress (DE') quite satisfactory.

متن کاملThe ultrastructure of calcareous cirratulid (Polychaeta, Annelida) tubes
The entire tube wall of Dodecaceria caulleryi and D. coralii is composed of thin calcareous lamellae with a spherulitic prismatic ultrastructure. In Diplochaetetes mexicanus the tube ultrastructure is similar, but contains also some lamellae with a homogeneous structure. The biomineralization system of cirratulids has not evolved since the appearance of calcareous tubes in the Oligocene. The tu...
