“…Since that review some gaps have been filled by Tait et al (1984) and Julli (1986) from Magela Creek billabongs, and Hawk& (1988) from Solomon Dam. These studies are not readily comparable: the Magela billabong 'plankton' contained a high proportion of littoral incursions with resultant high species diversity, a consequence of habitat heterogeneity, and many species are better considered as littoral microfauna.…”

General ecological expectations about the relationship between latitude and species richness are that at low latitudes (the tropics) species richness is greater than at higher latitudes (temperate and polar regions). Recent work suggests that this may not be the case for several habitat types and biological groups in Australia. Results are conflicting: on present evidence (admittedly sparse) it appears that in Australian tropical fresh waters species richness is generally depressed in zooplankton and littoral microfaunal communities, but not in macroinvertebrate communities in typical streams and in fish communities (and perhaps also in amphibian and reptile communities).The situation is indeterminate for tropical phytoplankton and macrophyte communities.

“…Only when river water penetrates the levee will the floodplain be in contact with flowing water. Inundation of the floodplain may increase zooplankton abundance in the main stem by flushing the standing or slowly flowing waters of the floodplain into the river (Saunders and Lewis 1988a,b;Tait et al 1984).…”

Zooplankton were sampled quantitatively in the lower Orinoco River and three major tributaries (Apure, Caura, Caroni). Dominant taxa were euplanktonic, which suggests origin from standing waters. In the Orinoco, densities for rotifers (mean, 7.6 ind. liter -I) were greater than those for cladocerans (0.9 ind. liter-I) or copepods (1.2 ind. liter-'), but cladocerans accounted for more than half oftotal biomass (0.5 kg C liter -I). Average tributary contributions to zooplankton transport in the lower Orinoco (873 kg C d-l) were proportional to their average discharges. Extensive fringing floodplain along the lower Orinoco contributed very little to total transport. At low water in the Orinoco, when there was no contact with the floodplain, the transport of copepods (mainly nauplii) and Bosmina increased downstream by more than could be ascribed to additions from the tributaries or to reproduction in transit. These zooplankton appear to originate along the river margin, within the channel, and arc probably significant as an energy input for food webs in the channel and as an inoculum to floodplain habitats at the time of inundation.

Bayly, 1961Bayly, , 1964Bayly, , and 1966 on calanoid copepods) and from recent seasonal studies (Hawkins, in press ;Julli, 1986 ;Tait, 1981 ;Tait et al, 1984) . Preliminary analyses of the structure of zooplankton communities have been made by Dussart et al (1984), who lamented lack of knowledge for Australasia compared to other tropical areas of the world .…”

Crustacean zooplankton assemblages in freshwaters of tropical Australia

Throughout tropical Australia eulimnetic zooplankton is composed of 7 calanoid copepods, 5 cyclopoid copepods and 12 cladocerans . A further 10 cyclopoids and 9 cladocerans occur as littoral `strays', making 43 species in all . Dominants include Diaptomus lumholtzi, Mesocyclops notius, Thermocyclops decipiens, Diaphanosoma excisum, Ceriodaphnia cornuta, and Moina micrura. Momentary species composition averages 1 .0 calanoids, 1 .3 cyclopoids and 2 .0 cladocerans . These assemblages are not only less complex than in temperate Australia, but also are not as rich as in most other tropical regions . The main contributors to these differences are calanoids and cladocerans respectively . Nevertheless, as elsewhere, most zooplankters in tropical Australia are eurytropic, widely distributed and small .
