Vertical distribution of eight copepod species across 0-1000 m in Sagami bay in 21-27 April 2009.
White and black boxes denote daytime and nighttime distributions. Scaphocalanus echinatus/em> is taken from Kuriyama & Nishida (2006).
Plankton and water samples collected from a fixed station (35°00'N, 139°20'E) using MTD horizontal closing nets (0.33 mm mesh aperture) at 15 depths (0, 50, 95, 100, 150, 195, 200, 295, 300, 395, 400, 500, 600, 800, 1000 m) during both day and night.

Second maxilla 'Mx2) and maxiliped (Mxp) from Undeucharta major.
Scale bars: 200 µm.
Nota: The C and N values coincided with the plots assumed for potential consumers of oncaeid copepods and epipelagic particulate organic matter (POM). The microscopic gut-content analysis indicated the ingestion of crustaceans fragments and absence of autofluorescence in all specimens, as well as the presence of maxillipeds of oncaeid copepods and A2 of corycaeid copepods in many specimens. The observations indicate that the species mainly ingested crustaceans, diatom particles may be derived from the gut contents of ingested zooplankton. Oncaeids are one of the most numerous groups in oceaniccopepod communities, particularly in meso- and bathypelagic zones (c.a Böttger-Schnack, 1996; Yamaguchi & al., 2002).
Compare appendage structure and setal armement with Euchirella rostrata, Chirundina streetsii, Pleuromamma xiphia, Scaphocalanus echinatus, Scottocalanus helenae, Scottocalanus securifrons, Spinocalanus magnus and calanus sinicus for interpreted particles catching. |
