Ascidiidae Herdman, 1882 (Tunicata: Ascidiacea) on the Pacific coast of Panama.
The ascidian fauna of the Pacific coast of Panama is poorly known and only recently four species in the family Ascidiidae were reported on. Ascidia is the only known genus of Ascidiidae in Pacific Panama waters. In the present research, we describe a new species, Ascidia sideralis sp. nov., and we document the new occurrence of A. cf. gemmata and A. cf. liberata (both previously known to the We...
متن کاملNew species of Didemnidae (Tunicata: Ascidiacea) from the tropical coast of Brazil.
The family Didemnidae includes 20% of all known ascidians with six genera in the Atlantic. Here, we describe five new species in the Didemnidae from central coastal Brazil. Four species are in the genus Didemnum and were found in Bahia (D. aurantium, D. flammacolor, D. lambertae, D. longigaster), while one Diplosoma (D. citrinum) was found both in Bahia and Espírito Santo.
متن کاملNew distributional data on ascidian fauna (Tunicata: Ascidiacea) from Mandapam coast, Gulf of Mannar, India
BACKGROUND Ascidians play a key role in the ecology and biodiversity of marine ecosystem. Ascidians can be transported in ship ballast water and while attached to ship and boat hulls. Heavy traffic by domestic and international ships as well as cargo vessels between the major and minor ports warrants continuous monitoring for new introductions of ascidians. The Mandapam coast is situated in the...
متن کاملCytotoxicity of the crude extracts of Marine ascidians (Tunicata: Ascidiacea) from Tuticorin, Southeast coast of India
Marine organisms such as ascidians, sponges and soft corals, containing symbiotic microorganisms are a rich source of bioactive compounds. This study examined the cytotoxic potential of two ascidians found in the coastal waters of Tuticorin. The ascidians samples Didemnum psammatode and Phallusia arabica were extracted in methanol and ethanol. The crude extracts were tested for cytotoxicity usi...
متن کاملHuman-mediated global dispersion of Styela plicata (Tunicata, Ascidiacea)
Styela plicata (Lesueur, 1823) is a solitary ascidian found in shallow, protected environments in tropical and warm-temperate oceans. Its origin is uncertain, given that it has already been identified in several oceans since it was first described, showing a very broad geographical distribution. Although S. plicata has been historically classified as a cosmopolitan species, in the past few deca...
