| Abstract |
A benthic copepod community has been monitored over seven years (1970-6). The density of the different species and total density, diversity, species richness, biomass and respiration of the copepod community were analysed using Maximum Entropy Spectral Analysis. The spectrum of density shows the existence of long-term cyclicity in most species, although the annual cycle is always important. This long-term cyclicity can be explained partially by salinity changes in the habitat and partially by the intensity of decomposition processes. Diversity and species richness have long-term components as well, and these are also related to salinity changes to which the community appears to adjust with a lag of one year. The functional characteristics of the community, especially respiration, do not show significant cyclicities of longer than two years and the annual cycle is predominant. |
