Bi-Hemispheric Distribution and Ecology of the Commensal Amphipod Leucothoe nagatai Ishimaru, 1985 (Crustacea: Leucothoidae)
Abstract:Reports on the taxonomy and distribution of the amphipod crustacean Leucothoe nagatai Ishimaru, 1985, are discussed including significant range extensions from the type locality in the Sea of Japan. This research was based on existing museum specimens, and in situ collections of new material. Originally described from the branchial chamber of the solitary ascidian Styela plicata (Lesueur, 1823), several new ascidian and sponges host species from California and New Zealand are documented for L. nagatai. Molecular studies confirm that northern and southern hemisphere populations are genetically indistinguishable. Color patterns in live and freshly preserved specimens of L. nagatai are diagnostic across its geographic range aiding in identification by nontaxonomists. Feeding habits of leucothoids within their invertebrate hosts are elucidated and discussed. Figures and plates of known invertebrate hosts, color patterns, and taxonomic structures are included.
期刊介绍:
Pacific Science: A Quarterly Devoted to the Biological and Physical Sciences of the Pacific Region
The official journal of the Pacific Science Association. Appearing quarterly since 1947, Pacific Science is an international, multidisciplinary journal reporting research on the biological and physical sciences of the Pacific basin. It focuses on biogeography, ecology, evolution, geology and volcanology, oceanography, paleontology, and systematics. In addition to publishing original research, the journal features review articles providing a synthesis of current knowledge.
