chordate

Protochordate allorecognition is controlled by a MHC-like gene system.

Historical introduction, overview, and reproductive biology of the protochordates. Can.

These observations suggest that recruitment of supplementary transcription factor(s) into the regulatory cascade must have occurred during the transition from protochordates to vertebrates.

Taxa ranging from algae to higher plants, and from cnidarians to protochordates, grow through the iterated replication of individual modules to form large, integrated individuals or colonies (Jackson et al., 1985).

Studies of fused allogeneic colonies of the protochordate Botryllus schlosseri have shown that the eggs of one partner may be retained and brooded by the other partner over several reproductive cycles (Sabbadin and Zaniolo, 1979).

Two new forms of gonadotropin-releasing hormone in a protochordate and the evolutionary implications.

Allorecognition elements on a protochordate histocompatibility locus indicate unprecedented extensive polymorphism.

General diet description Red porgy had a diverse diet, composed of 188 different taxa that belong to 18 taxonomic groupings: decapods, bivalves, polychaetes, gastropods, bryozoans, unidentified crustaceans, echinoderms, bony fishes, barnacles, miscellaneous (e.g., fish scales and foraminifera), tunicates, amphipods, squid, cnidarians, stomatopods, isopods, ostracods, and protochordates. Decapods, barnacles, and bivalves were the main prey of red porgy, accounting for 44%, 20%, and 11% of the diet by weight, respectively (Fig.
