Аннотация: A new method of estimating non-predatory mortality of zooplankton based on live/dead sorting and sediment trap measurement is described. Preliminary results on Daphnia cucullata and Daphnia longispina are given. Estimations of average non-predatory mortality demonstrated a significant contribution of this kind of mortality to total mortality.

Ключевые слова (''Своб.индексиров.''): individual-based model--cladocera--change of reproduction mode--metabolic by-products
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. (C) 2002 Elsevier Science B.V. All rights reserved.

Аннотация: Morphological analysis of muksun Coregonus muksun of the Khatanga River basin revealed that along with its typical high-density-rakered form, individuals of the low-density-rakered form also live in this region. Analysis of the genetic polymorphism of three marker regions of mitochondrial (ND1 and COI fragments) and nuclear (ITS1) DNA indicates the polyphyletic origin of these forms. The revealed low level of genetic differentiation of muksun and whitefish C. lavaretus, along with the available data on the absence of clear diagnostic species characteristics, suggest that they belong to the same biological species C. lavaretus.

Ключевые слова (''Своб.индексиров.''): whitefish--coregonus lavaretus--morphological analysis--craniological--analysis--genetic polymorphism--mitochondrial dna
Аннотация: The results of a study of the specific features of morphological and genetic polymorphism of the population of the anadromous White Sea common whitefish (Coregonus lavaretus L.) from the Keret' River are presented. As assessed by its morphological features, the whitefish population of the Keret' is homogenous. A comparison of the Keret' whitefish with whitefish populations of both Europe and Siberia revealed clear differences. These differences relate first and foremost to the fish locomotion and orientation in space: body depth, length and positions of fins, and interorbital width. The characteristics of skull features (craniological analysis) of the White Sea whitefish are presented for the first time. The results of an analysis of the polymorphism of the ND1 fragment of the mitochondrial DNA confirmed an earlier suggestion about the mixed origin of the Keret' River whitefish: the descendants of three different phylogenetic lineages were revealed in the population.

Заглавие : The influence of food concentration and "water aggregation" on the reproductive parameters of Moina macrocopa (Crustacea : Cladocera) females

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 mu 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.
