The influence of a predatory ostracod, Australocypris insularis, on zooplankton abundace and species composition in a saline lake

Abstract: The influence of the predatory ostracod Australocypris insularis on zooplankton abundances and species composition in an Australian saline lake was monitored over 8 months in aquaria and tank microcosms . Control, Predator (double A . insularis Control densities) and No Predator (all A. insularis removed) treatments were set up in small 11 .5 1 aquaria and large 883 .5 1 tanks . Microcosm salinities were manipulated to accord with seasonal lake salinities and ranged from 35 to 110 g 1 -1 . Densities of the cal… Show more

“…LIPEROVSKAYA (1948) examined the gut contents of nine ostracod species collected from natural systems with a bottom sampler; algae were generally abundant, and remains of daphniids and oligochaetes were present in three of them (Heterocypris incongruens, Cypris pubera, and Dolerocypris fasciata. and small ostracods in aquaria (CAMPBELL, 1993(CAMPBELL, , 1995. Her study appears to be the first and only one showing that an ostracod may prey on rotifers.…”

“…However, our observations are not completely unexpected, as carnivory and scavenging behavior has been reported across a number of ostracod taxa. The relatively large ostracod, Australocypris insularis, is endemic to Australian saline lakes (De Deckker, 1983), consumes zooplankton (De Deckker and Geddes, 1980), and can influence the structure of zooplankton communities of saline lakes (Campbell, 1995). Under experimental conditions, several species (Cypridopsis hartwigi, C. vidua, Cypretta kawatai) have been observed to consume the soft parts of snails (Sohn and Kornicker, 1975;Delorme, 1991), including C. vidua reported here to consume Green Frog eggs.…”

“…The eggs of ostracods are capable of withstanding both desiccation and freezing, which allows them to inhabit many ephemeral environments (Delorme, 2001). Ostracods typically eat algae and detritus (Meisch, 2000;Delorme, 2001), although some species consume zooplankton (De Deckker and Geddes, 1980;Campbell, 1995) and others the soft parts of living and dead snails and other animals (Sohn and Kornicker, 1975;Wilkinson et al, 2007). Ostracod grazing and predation can be severe enough to limit the distribution of algae (Wickstrom and Castenholz, 1985) or change zooplankton community structure (Campbell, 1995).…”

“…Most free-living freshwater ostracods consume mainly algae, cyanobacteria and organic detritus, but have also been reported to feed on bacteria, fungi, protozoans, plants and pollen, fallen leaves, rotifers, oligochaetes, nematodes, copepods, cladocerans, chironomids, mosquito larvae, gastropod larvae, amphibian eggs, fish fry, assorted dead animals and even other ostracods, including individuals of the same species (Liperovskaya, 1948;De Deckker, 1983;Strayer, 1985;Campbell, 1995;Fryer, 1997;Smith and Delorme, 2010;Gray et al, 2010;Ottonello and Romano, 2011;Rossi et al, 2011). Ostracods are not widely reported to directly feed on rice plants, but in experiments, ostracods have been documented damaging the roots of two-week old rice seedlings suspended in water (Barrion and Litsinger, 1984).…”
