parasite diversity of nyctiphanes simplex and nematoscelis difficilis (crustacea: euphausiacea) along the northwestern coast of mexico.the diversity of parasites found on nyctiphanes simplex and nematoscelis difficilis (order euphausiacea) was compared during 10 oceanographic cruises made off both coasts of the baja california peninsula, mexico. we tested the hypothesis that n. simplex has a more diverse parasitic assemblage than n. difficilis because it is a neritic species, has larger population abundance, and tends to form denser and more compact swarms than n. difficilis. these biological and behavioral features may enhance ...201020377014
pseudocollinia brintoni gen. nov., sp. nov. (apostomatida: colliniidae), a parasitoid ciliate infecting the euphausiid nyctiphanes simplex.a novel parasitoid ciliate, pseudocollinia brintoni gen. nov., sp. nov. was discovered infecting the subtropical sac-spawning euphausiid nyctiphanes simplex off both coasts of the baja california peninsula, mexico. we used microscopic, and genetic information to describe this species throughout most of its life cycle. pseudocollinia is distinguished from other colliniidae genera because it exclusively infects euphausiids, has a polymorphic life cycle, and has a small cone-shaped oral cavity whos ...201222585303
community structure of zooplankton in the main entrance of bahía magdalena, méxico during 1996.the zooplankton community structure, including copepods, euphausiids, chaetognaths, and decapod larvae, was monitored during six circadian cycles using bongo net (500 microns mesh net) samples from bahía magdalena, on the southwest coast of baja california, méxico. samples were obtained during three oceanographic surveys (march, july, and december 1996) to describe the changes in the zooplankton community structure throughout the main mouth of bahía magdalena. the zooplankton community structure ...200111935905
