Pattern and persistence of a nearshore planktonic ecosystem off Southern California

Adult demography and larval processes in coastal benthic populations intertidal barnacles in Southern California and Baja California

“…50 km north of our sampling station, Barnett and Jahn (1987) found that total cyprids (species not identified) were consistently more abundant near the bottom and within 4 km from shore. Pineda (1991) found unidentified cyprids that were more abundant near the bottom than at the surface in shallow waters (4.16 m)…”

“…Although the observed chlorophyll values were rather low for coastal waters (e.g. Barnett and Jahn 1987;Phillips 2005), nauplii were expected to occur at depths with the highest pigment concentration if their constant vertical distribution is to be interpreted as an adaptation for feeding. Transient increases in near-surface and mid-depth chlorophyll fluorescence associated with high-frequency (~2 cycles hl ) internal waves have been observed during spring and summer in this area (Lennert-Cody and Franks 2002).…”

Environmental variability and biogeography: the relationship between bathymetric distribution and geographical range size in marine algae and gastropods

“…Our interpretation of the macroecological patterns we describe hinges on the assumption that environmental variability decreases with depth. Such a decline in variability has been documented for a suite of environmental variables, including temperature, salinity, and nutrients (Barnett & Jahn, 1987;Pickard & Emery, 1990). Temperature in particular is a crucial abiotic variable because it has demonstrable effects on the physiology and fitness of marine organisms (reviewed in Tomanek & Helmuth, 2002), and because it is related to both latitudinal and bathymetric ranges of benthic marine species (e.g.…”

Using low volume eDNA methods to sample pelagic marine animal assemblages

“…Clusters N1 and N2 were the most diverse ( Fig 7B and S7 Fig in S1 File ). N1 was mostly comprised of an assemblage of copepods with peak occurrences in the upper 100 m of the water column in coastal and offshore waters off southern California (e.g., Ctenocalanus vanus , Ditrichocorycaeus anglicus [ 66 , 67 ]). N2 contained roughly equal frequencies of cnidarians and copepods, dominated by species distributed throughout the water column in the southern region of our study area (e.g., Liriope tetraphylla and Ctenocalanus vanus [ 68 ]).…”
