Consumption of Microorganisms by the Copepod Tigriopus Californicus

Habitat characters of Tigriopus californicus (Copepoda: Harpacticoida), with notes on the dispersal of supralittoral fauna

“…The bedrock may be granite, limestone, or shale, but a common feature is the protrusion of shelf rocks or benches, forming a raised platform angling sharply into the sea (cf. Lear & Oppenheimer, 1962;Harris, 1973). Flattened foreshores, which £ood gradually with the incoming tide and immerse pools by several centimetres appear to be less e¡ective at retaining T. californicus populations, perhaps due to the retention of more potential predators or the magnitude of hydrodynamic e¡ects on any microcrustaceans swimming above the bottom.…”

“…Since the earliest descriptions of the genus Tigriopus, its congeners have become familiar subjects in a variety of mensurative and manipulative studies of harpacticoid copepod biology (e.g. Fraser, 1936a,b;Provasoli et al, 1959;Lear & Oppenheimer, 1962;Huizinga, 1971;Harris, 1973;Battaglia et al, 1978;Dethier, 1980;Burton & Feldman, 1981;Kahan et al, 1988). Tigriopus copepods are found on the supralittoral fringe of nearly every ocean, including the shores of Japan (Tigriopus japonicus), northern Europe (T. brevicornis), the Adriatic (T. fulvus), North America (T. californicus), and New Zealand (the congeners T. angulatus and T. raki).…”
