Contrary to the negative growth rates of Elosa on heterotrophic C. acidophila in our single-species results (Table I) and in Weithoff and Wacker (Weithoff and Wacker, 2007), Elosa exhibited slightly positive growth rates in the competition experiment with heterotrophic food, but only high enough to compensate for the dilution rate. Koste, W., 1973. 38: 721–724. 1). In detail: High light, autotrophic conditions favoured the growth of Elosa and allowed for high positive growth rates and abundances (Table I, Fig. 35: 795–808. Diploma thesis, University of Rostock. Pilarska, J., 1972. For determination of the carbon content of the algae, algal suspensions were filtered on precombusted Whatman filters (GF/F; Whatman International Ltd, Maidstone, UK) and carbon was measured with a HighTOC (Elementar Analyse System GmbH, Hanau, Germany).

We found strong reductions in growth rate, cell length, total fatty acid content and especially α-linolenic acid (18:3n-3; ALA) content in heterotrophically grown C. acidophila. This reflects the pure competitive exclusion principle. Field experiments have indicated that rotifer grazing should generally play a minor role in bacteria consumption compared to feeding by coexisting protozoans. In lakes of the mining district of Lusatia, Germany, with pH <3, rotifers are the only planktonic metazoa, typically Elosa worallii and Cephalodella sp. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Some species of fungi and bacteria are classified as heterotrophs. 39: 103–111. Oceanogr. To qualify as an autotroph, an organism must be able to make its own sugars and other organic substances from inorganic substances. Abundances of heterotrophic (HF), autotrophic (AF), and mixotrophic (MF) nanoflagellates in Lake Oglethorpe, Georgia, were in the range 10 2 –10 4 cells ml −1.Pigmented and nonpigmented flagellate abundances were positively correlated with each other in samples spanning a year, but were not significantly correlated to the same physical parameters (temperature, oxygen, light). int.

Phototrophic picoplankton: An overview from marine and freshwater ecosystems. In Lake 111 (Lusatia, Germany), C. acidophila regularly builds up a deep chlorophyll maximum (DCM) at a water depth at which the light availability is reduced to <1% of surface irradiation (Tittel et al., 2003; Kamjunke et al., 2004).

Recent investigations have shown that processes within the planktonic microbial web are of great significance for the functioning of limnetic ecosystems.

Ser., EPA-600/3-77-051, 50 pp. Under low light conditions (c), both, autotrophic and mixotrophic, Cephalodella tended to dominate over Elosa, and this pattern was more pronounced under heterotrophic conditions (d). The initial food concentration was above the limiting conditions for rotifer growth: 2.5 mg C L−1 for auto- and mixotrophic algae and 1.9 mg C L−1 for heterotrophic algae (Weithoff, 2005, 2007).

Additional experimental work is necessary for a better understanding of the function of rotifers in aquatic ecosystems. It has been argued that heterotrophic nitrification involves enzyme systems that are quite different from those of the autotrophs (Wehrfritz et al., 1993) and that heterotrophic nitrification cannot serve as an energy generating mechanism (Castignetti, 1990), as the autotrophic process does. Low temperature, reduced light and consequent changes in autotrophic and heterotrophic resources alter the diet for long-lived consumers, with consequences on their metabolism in winter. Dr W.

When algal concentration fell below the initial conditions, fresh algal suspension instead of pure medium was added, resulting in a mean food concentration >1.1 mg C L−1. Hydrobiologia 159: 63–73. Oceanogr. Rotifers, whose downstream decrease, may be attributed to excavation works and was accentuated by invertebrate prédation, were one of the causes of the increase of green algae at the lower site. Rotifers, who make up the part of the phylum Rotifera, are heterotrophs. Freshwat. Ergebn. Fenchel, T., 1987. Under heterotrophic conditions, Cephalodella was the superior competitor with significantly higher growth rates and density (Table I, Fig. Limnol.

Tax calculation will be finalised during checkout. Oceanogr. Deep Sea Research 36: 483–495. From those data, cell numbers of C. acidophila were converted into carbon units. 1 Temporal changes in abundances of microflagellates (autotrophic and heterotrophic) and rotifers (Synchaeta species 1, Syn, sp. Since Elosa has a lower food threshold than Cephalodella (Weithoff, 2007), the observed low competitive ability is not due to low food quantity and can only be explained by food quality. Photoautótrofos are all those organisms that, as its name indicates, whose energy depends on the photosynthesis. available. Jacobs, J., 1974. Microscopy 35: 535–538. J. Verh. We have chosen an intermediate approach by supplementing algae back to initial conditions every second day. Recently, Weithoff and Wacker (Weithoff and Wacker, 2007) showed that the mode of carbon acquisition differentially determined the food quality for the two rotifers; in particular, Cephalodella sp. Gilbert, J. J., 1976. A general approach to the culture of planktonic rotifers. Beih. This resulted in an opposite pattern compared with autotrophic (HL) conditions and was in line with previous results demonstrating that mixotrophic food is of lesser quality for Elosa (Weithoff and Wacker, 2007); although, in that study, Elosa was more strongly affected by mixotrophic C. acidophila. Springer-Verlag, New York: 209–227. Thus, the exploitation by zooplankton of this quantitatively rich resource might be hampered by the resource quality.

About 10–40 per cent of rotifers' food can consist of heterotrophic organisms of the microbial web. Another important role of rotifers is their feedback effect on the microbial web. DeBiase, A.
