The North Pacific central gyre is a large, monotonous, and geologically old system. It (and other such gyres) is probably the nearest oceanic equivalent to an essentially self-regulating, climax ecosystem. We have taken a series of replicated, vertically stratified net tows for macrozooplankton and have replicated measures of a number of habitat variables.Copepods are the most numerous members of the macrozooplankton fraction of the community of the central gyre. It is likely that they are also the largest part of the biomass. There are at least 125 species regularly present and although we do not know what many of them eat, certain species can almost certainly be identified as herbivores or carnivores, and others as omnivores. We show that some species are significantly more frequent parts of each other's biotic environment than other species. These recurrent groups of species tend to occupy different depth zones. The members of the groups show strong concordance of abundance at the depth of high group coherence. Thus there is a dividing up of the water column and a clear tendency for vertical spatial structure in the copepod fauna. Within groups there is a significant constancy of dominance at the group's preferred depth over time. Thus there appears to be a large amount of species structure as well as spatial structure. A highly regulated species equilibrium is implied. There are congeners occurring within the same recurrent groups.The physical and biotic environment of each group differs with respect to both concentration (e.g., chlorophyll a) or magnitude (e.g., temperature) of habitat variables and with respect to the spatial variability of these. Our most diverse group tends to occupy a depth zone ranking high in primary productivity but does not have the greatest total environmental "richness" or greatest or least heterogeneity, and this seems contrary to what some current community theory predicts. Our evidence indicates that within groups many similar species coexist spatially and temporally.We speculate about the relative roles of competition and predation in influencing the structure we see. Aspects of modern community theory, based on competitive equilibrium, seem inadequate to explain our results. Predator regulation of structure seems a more likely explanation. However, existing information indicates a lack of sufficient specialization of what we believe to be the main predators on copepods to account for the observed constancy of copepod species structure.We suggest that a more intensive study of the role of predation is in order.

Predicting crustacean zooplankton species richness

“…Thus, larger lakes have more habitats than small lakes, and different zooplankton species are adapted to these different habitats (Hutchinson 1967;Stoddard 1987;Watson and Wilson 1978). Similarly, patterns of species associations suggest that open-ocean pelagic habitats, which are probably similar to largelake pelagic habitats, can be partitioned into five or more subhabitats (McGowan and Walker 1979).…”

“…The North Pacific Central Water Mass has a surface area of about 1.5 x 10L3 m2. It is inhabited by -325 species of macrozooplankton (McGowan and Walker 1979), ofwhich perhaps 200 are crustaceans. Extrapolation from the relationship in Fig.…”

Community structure in pelagic marine mammals at large spatial scales

“…Relatively little research has been done on the community structure of pelagic marine organisms, most likely due to the difficulty of gathering such data (Venrick 1990). Despite these difficulties, research in pelagic systems has shown clear gradients and structure in the following pelagic communities: marine phytoplankton (Venrick 1982(Venrick , 1990; marine zooplankton (McGowan & Walker 1979, 1985; marine birds (Ballance et al 1997, Woehler et al 2003, Hyrenbach et al 2007; and marine mammals , Baumgartner et al 2001, Hamazaki 2002, Palacios 2003.…”

The implications of the precautionary principle for biological monitoring

“…Meanwhile, the difficulties of experimental manipulation in open water is an important reason why ecologists such as McGowan & Walker (1979) and Dayton (1984) were forced to concede that little progress has been made in resolving the "paradox of the plankton" (that vast numbers of species apparently find ways of coexisting in this simplest possible of habitats), pointed out over 30 years ago by Hutchingson (1961). And while the current emphasis on physical processes in planktonic ecology gives another dimension to the analysis (cf.…”
