Infochemical-mediated trophic interactions between the rotifer Brachionus calyciflorus and its food algae / A. M. Verschoor, Y. S. Zadereev, W. M. Mooij // Limnology and Oceanography. - 2007. - Vol. 52, Is. 5. - P2109-2119 . - ISSN 0024-3590

Аннотация: We studied how chemicals obtained as filtrates from algal monocultures (algal chemicals) and from rotifer cultures with or without algae (rotifer chemicals) affected feeding rates of the rotifer Brachionus calyciflorus on its food algae, both directly and indirectly (through chemical-induced changes in algal morphology). Algal chemicals had a strong stimulating effect on the feeding rate of B. calyciflorus, but these effects were counteracted by rotifer chemicals. In functional response experiments, rotifer chemicals lowered maximum ingestion rates and had strong effects on assimilation rates and assimilation efficiencies of B. calyciflorus, probably due to the release of unspecific (auto)toxic metabolites. Furthermore, rotifer chemicals induced colony formation in the food alga Scenedesmus obliquus. Above the optimum particle size for ingestion by B. calyciflorus, larger algal colony sizes increased the food-handling time, thus lowering ingestion and assimilation rates. Through their effects on trophic interactions, infochemicals may play a role in structuring and the functioning of aquatic food webs.

Competition between links in "producers-consumer" trophic chains in an aquatic closed system with spatially separated components / T. I. Pisman, N. S. Pechurkin, L. A. Somova // Advances in Space Research. - 2001. - Vol. 27, Is. 9. - P1599-1603, DOI 10.1016/S0273-1177(01)00255-1 . - ISSN 0273-1177

Аннотация: The work analyzes functioning of a "producer-consumer" closed aquatic system with spatially separated links, where each component consisted of two species. Producers in the system were the microalgae of Chlorella vulgaris and Scenedesmus sp., consumers - Paramecium caudatum infusoria and Brachionus sp. rotifers. In the experiment the competing predators were consuming on a mixed culture of algae, and the competition of algae was studied under nitrogen limitation. Under these conditions competitiveness of Scenedemus was higher than that of Chlorella vulgaris. Metabolism products of Scenedesmus algae have been found to have negative effect on reproduction of Paramecium caudatum protozoa. Predator population dynamics in the "consumer" link demonstrated that the rotifers that consume two algal species are more competitive compared to protozoa feeding on chlorella only. В© 2001 COSPAR.

Аннотация: Изучена конкуренция хищников (в звене консумента) при потреблении ими смешанной культуры водорослей (в звене продуцента), а также конкуренция водорослей при лимитировании их роста в звене продуцента. Показано, что при выращивании смешанной культуры водорослей (в звене продуцента) в условиях лимитирования роста азотом, водоросли Scenedesmus оказались более конкурентоспособными по сравнению с Chl. vulgaris. На основании динамики численности хищников в звене консумента показано, что коловратки, потребляющие два вида водорослей, вытесняют инфузорий, потребляющих только хлореллу.

Аннотация: An experimental investigation was carried out, and a mathematical model of interaction between invertebrates (infusoria Paramecium caudatum and rotifera Brachionus plicatilis) and algae (Chlorella vulgaris and S enedesmus quadricauda) in the <> aquatic biotic cycle with spatially divided links was constructed. The model describes the dynamics of a mixed culture of infusoria and rotifera in the <> link, when they consume a mixed culture of algae coming from the <> link. A negative influence of products of algae Scenedesmus metabolism upon the reproduction of infusoria P. caudatum was revealed. Taking this into account, a qualitative coincidence of the results of mathematical modeling with experimental data was obtained. It was shown that the co-existence of mixed algae culture in the <> link with invertebrates in the <> link in the <> aquatic biotic cycle is impossible because of the displacement of infusoria P. caudatum by rotifera Brachionus plicatilis.

Аннотация: Three levels of chemical communications involved plankton Crustacea are considered: 1) Influence of zooplankton excretion on phytoplankton; 2) Influence of zooplankton excretion on the individuals of the same or other species of the same trophic level; 3) Influence of chemical cues released by predatory zooplankton and fish on herbivorous zooplankton. The data on the influence of excreted cues on some physiological (growth, reproduction, feeding, etc.) and behavioural (vertical and horizontal migrations) characters of planktonic crustaceans are presented. Ecological role and chemistry cues responsible for the interactions of different trophic levels can be different. It is considered that chemical communications in aquatic ecosystems can be provided with: 1) Species-specific cues that strictly influence particular biological functions (communication system of feromone type); 2) Non-specific cues that strictly influence particular functions (system of regulator, that act at the whole ecosystem as the hormonal system of an organism). 3) Non-specific substances with broad (nonspecific) influence-toxic substances of "biocondition substances" according to classification of Novikov and Kharlamova (2000).

Аннотация: The functioning of a closed aquatic consumer-producer system with spatially separated links, with each link consisting of two species, is considered. Competition between the consumers (infusorians Paratnechan caudatum and rotifers Brachionus sp.) feeding on a mixed algal culture (Chlorella vulgaris and Scenedesmus sp.) and competition between these algae under conditions of limited nitrogen supply are analyzed. It is shown that Scenedesmus algae have an advantage over C. vulgaris in terms of competitiveness, and their metabolic products have an adverse effect on reproduction in infusorians.

Кл.слова (ненормированные):
competition -- metabolite interaction -- principle of competitive exclusion
Аннотация: This paper presents a mathematical model of interactions between two herbivorous invertebrates (ciliate Paramecium caudatum and rotifer Brachionus plicatilis) and two planktonic algae (Chlorella vulgaris and Scenedesmus quadricauda) spatially segregated in two compartments of a chemostat - type experimental microcosm system. The model mimics a "producer-consumer" aquatic biotic cycle, describing the dynamics of the mixed culture of ciliates and rotifers, as "consumer" compartment, feeding on the mixed algal culture, as "producer" compartment, under N-limiting conditions. We experimentally found that metabolites of the alga Scenedesmus produce an adverse effect on the reproduction of ciliate Paramecium. Taking this effect into account improved the behavior of the model, the results of which came into qualitative agreement with the experimental results. Both our experimental and modeling approaches demonstrated that, even in conditions of a spatially - segregated "producer-consumer" biotic cycle, species coexistence is impossible either in the mixed algal culture or in the mixed invertebrate culture. Scenedesmus excluded Chlorella, whereas Brachionus excluded Paramecium.

Аннотация: This study assesses the comparative sensitivity and possibility of obtaining fast results of various methods of biotesting for several surfactants: Tween 85, sodium dodecyl sulfate (SDS), Fairy dishwashing gel, and Mif washing powder. The following test organisms are used for the study: luminescent bacteria Photobacterium phosphoreum (Beijerinck), preparation of Ecolum luminescent bacteria, unicellular algae Scenedesmus quadricauda (G.M. Smith), infusorian Paramecium caudatum (Ehrenberg), and crustacean Daphnia magna (Straus). It has been revealed that Fairy dishwashing gel possesses the strongest toxicity against the studied test objects. Daphnia and algae are most sensitive to the effects of Fairy and SDS, protozoan and luminescent bacteria are most sensitive to SDS, and Ecolum is most sensitive to Mif washing powder. The tested aquatic organisms and Ecolum are most tolerant to the effect of Tween 85. © 2016, Pleiades Publishing, Ltd.
