Individual-based model of the reproduction cycle of Moina macrocopa (Crustacea: Cladocera) / E. S. Zadereev [et al.] // Ecological Modelling. - 2003. - Vol. 162, Is. 1-2. - P15-31, DOI 10.1016/S0304-3800(02)00348-4 . - ISSN 0304-3800

Аннотация: An individual-based model of cyclic development of Cladocera populations was developed on the basis of experimental data. The model takes into account the following processes describing the development of an individual animal: maturation, transition into other reproductive classes, selection of the reproduction mode (parthenogenetic or gamogenetic), release of parthenogenetic progeny and death. The model assumes that switching from asexual to sexual reproduction is controlled by the concentration of food and metabolic by-products of the animal population. Verification of the model by independent experiments demonstrated that (1) during population growth, metabolic by-products build up in the medium, and (2) the effect of metabolic by-products on gamogenesis induction depends on concentration. The hypothesis that the effect of regulating reproductive switching factors should synchronise the development of population with the change of environmental conditions in order to ensure production of the maximum number of diapausing eggs was tested. It is shown that combination of regulating reproductive switching factors maximises the production of diapausing eggs. В© 2002 Elsevier Science B.V. All rights reserved.

Chemical composition of water conditioned by crowded Moina macrocopa (Crustacea: Cladocera) / G. S. Kalacheva [et al.] // Russian Journal of Ecology. - 2000. - Vol. 31, Is. 2. - P113-117 . - ISSN 1067-4136

Аннотация: The chemical composition of water conditioned by colonies of Moina macrocopa and involved in the regulation of their life cycle was analyzed in comparison with water samples from natural water bodies. Dechlorinated tap water was used as the control medium. The results showed that metabolism of crustaceans leads to an increase in the concentrations of phosphorus and nitrogen in all forms, the appearance of protein and carbohydrate fractions, and changes in the composition of lipid fractions in the water conditioned by their colonies. The contents of all organic components are very low, which makes their identification difficult. Concentrations of substances identified in the conditioned water do not exceed those occurring in nature. В© 2000 MAIK "Nauka/Interperiodica".

The influence of food concentration and "water of aggregation" on the reproductive parameters of Moina macrocopa (Crustacea: Cladocera) females / E. S. Zadereev, V. G. Gubanov, I. V. Egorov // Zhurnal Obshchei Biologii. - 1998. - Vol. 59, Is. 1. - С. 55-57 . - ISSN 0044-4596
Аннотация: Combined influence of "water of aggregation" and food concentration on the reproductive parameters of Moina macrocopa females was investigated. In all experiments the influence of population density was associated with the effect of "water of aggregation" prepared earlier by keeping dense population (200 ?g/ml) of M. macrocopa. It was shown that life-span of M. macrocopa females in "water of aggregation" was not dependent on food concentration; under conditions of all tested food concentration it was less than in case of control clean water. There was no difference in proportion of males produced in "water of aggregation" and in control though more males were born under conditions of higher food concentration. In general "water of aggregation" causes a specific acceleration of female life history: the life-span and the period between clutches decrease, the amount of neonates in last clutches increases while the chance of male production at the beginning of reproduction period becames greater. The "water of aggregation" could also causes the formation of ephipial eggs instead of the first partenogenetic clutch. It seems that life strategy under conditions of very high mortality associated with "water of aggregation" is aimed to maximum realization of individual capacities in short period of time.

The role of population density in gamogenesis induction in moina macrocopa (Cladocera: Crustaceae) / E. S. Zadereev, V. G. Gubanov // Zhurnal Obshchei Biologii. - 1996. - Vol. 57, Is. 3. - С. 366-367 . - ISSN 0044-4596
Аннотация: Combined influence of population density, temperature and photoperiod on the gamogenesis of individual females of M. macrocopa was investigated. In all experiments the influence of population density was associated with the direct effect of "swarm water". The photoperiod in its broad natural range also influences gamogenesis induction. The increase in temperature above optimum but lower than lethal level sharply decreases the efficiency of gamogenesis. In this case stimulation of gamogenesis is possible by combined effect of poor feeding and high population density. If temperature and photoperiod are optimum for partenogenetic population the change of reproduction mode in lowdensity population of M. macrocopa is determined by poor feeding while in high-density populations density itself is more important. However the increase in food concentration descreases the efficiency of "swarm water" on the gamogenesis induction. According to the hypothesis of nondirect influence of population density an individual decreases its filtarion rate (and starves) under "swarm water" condition.

The induction of diapause in Moina by species-specific chemical cues / E. Zadereev, T. Lopatina // Aquatic Ecology. - 2007. - Vol. 41, Is. 2. - P255-261, DOI 10.1007/s10452-006-9062-2 . - ISSN 1386-2588

Аннотация: The ability to change the reproduction mode and produce diapausing eggs, which is prevalent in many zooplankton species, significantly impacts on the evolution and ecology of aquatic communities. The production of diapausing eggs is controlled by multiple effects of biotic and abiotic factors, including infochemicals. We have investigated the effects of chemicals exuded by conspecifics and ecologically close competing congers, Moina brachiata and M. macrocopa, which coexist in the same water body, and by larger Cladocera species (Daphnia magna) on the change of reproduction mode, specific growth rate and fecundity of M. brachiata and M. macrocopa females. The production of gametogenetic eggs in both species was detected only in waters from crowded cultures of conspecifics. The water from crowded cultures of conspecifics reduced the specific growth rate of the juvenile females of both species that later switched to gametogenesis. While it either did not affect (in M. macrocopa) or even increase (in M. brachiata) the specific growth rate of the juvenile females that later reproduced by parthenogenesis. Females of M. macrocopa released significantly fewer neonates in the water from crowded cultures of conspecifics than in all other treatments, while the fecundity of M. brachiata females was the same in all treatments. To understand the phenomenon of diapause induction under the effect of chemical cues in zooplankton, a link between laboratory tests and ecological research should be established, and the chemical composition of the signals should be determined.

Maternal effects, conspecific chemical cues, and switching from parthenogenesis to gametogenesis in the cladoceran Moina macrocopa / Y. S. Zadereev // Aquatic Ecology. - 2003. - Vol. 37, Is. 3. - P251-255, DOI 10.1023/A:1025850417717 . - ISSN 1386-2588

Аннотация: The change in reproductive mode from parthenogenesis to gametogenesis in Cladocera is controlled by multiple environmental cues. Maternal effects are involved in the control of reproductive switching. In this study, we estimated the readiness of Moina macrocopa females to change reproduction mode under the effect of conspecific chemicals on maternal and offspring generations. The results demonstrated that information about the chemical environment was not transmitted between generations (none of the females produced diapausing eggs in the control medium irrespective of their mothers' environment). Differences in maternal energetic investments were not significant, hence the maternal environment did not affect the fecundity. However, tested animals adapted to the effect of the diapause inducing factor. When offspring of mothers cultured in crowded water were also cultured in crowded water (the constant effect of conspecific chemicals), they switched less readily to gametogenesis than offsprings of mothers cultured in fresh medium.

Аннотация: The allelopathic effect of population density on gametogenesis induction of Moina macrocopa (Crustacea: Cladocera) was investigated at varying food concentration, photoperiod, and temperature. The presence of the non-trophic effect of population density on gametogenesis induction was demonstrated. The experiments with single females have shown that if the photoperiod, temperature, and food concentration are favorable for parthenogenesis, the crowding water has the effect of stimulating females into changing the reproduction mode. This effect was enhanced by using a higher density of the population to achieve crowding. The change of reproduction mode occurs in the experiments with populations of M. macrocopa with the achievement of food availability favorable for the parthenogenesis of single females. Chemical interactions between animals are the most obvious explanation for the obtained results.

Maternal effects are involved in the control of reproductive switching. In this study, we estimated the readiness of Moina macrocopa females to change reproduction mode under the effect of conspecific chemicals on maternal and offspring generations. The results demonstrated that information about the chemical environment was not transmitted between generations (none of the females produced diapausing eggs in the control medium irrespective of their mothers' environment). Differences in maternal energetic investments were not significant, hence the maternal environment did not affect the fecundity. However, tested animals adapted to the effect of the diapause inducing factor. When offspring of mothers cultured in crowded water were also cultured in crowded water (the constant effect of conspecific chemicals), they switched less readily to gametogenesis than offsprings of mothers cultured in fresh medium.

Аннотация: The volatility and thermal stability of chemicals that are contained in the metabolic products of Moina macrocopa females that stimulate the production of diapausing eggs in these females have been studied in experiments with separately cultivated individuals. It has been shown that the gametogenesis-stimulating chemicals in this species are nonvolatile compounds: the effect of the medium that contains the metabolic products of the organism was not decreased after many hours of blowing with argon. Prolonged heating up to 80 degrees C also did not deactivate the ability of these products to change the reproductive mode. The effect of the medium that contains these products decreased after boiling, but if the possibilities of their oxidation or binding with salts of metals were excluded, they retained the ability to change the reproductive mode of the animals even after boiling.
