Intraspecies variation of reproductive strategies in perch (Perca fluviatilis)

Publikováno v: Biology Bulletin. 40:70-77

The variation of reproductive strategies in different populations of river perch and intrapopulation groups differing in the rate of growth have been analyzed. Using a bioenergetic approach, the origin and differences between these groups have been s

Ecological aspects of age-related dynamics of fish reproductive parameters

Autor: M. I. Shatunovskii, G. I. Ruban

Publikováno v: Russian Journal of Ecology. 40:320-327

On the basis of materials collected over many years, ontogenetic changes in reproductive parameters of ecologically different fish species (predators, benthophages, and zooplanktophages) have been analyzed in the light of Pianka’s (1981) concept of

Publikováno v: Journal of Ichthyology. 49:503-515

Structure and dynamics of populations of bream Abramis brama inhabiting water bodies of Eastern Europe of different types are investigated. With the consideration of the original and published data, the following issues are analyzed in populations fr

Some patterns of age and geographical variation in fish fecundity

Autor: M. I. Shatunovskii

Publikováno v: Biology Bulletin. 33:195-198

Some patterns of age and geographical variation in fecundity indices were analyzed in three freshwater fishes (river perch, bream, and Sevan khramulya). A trend to increase in the ovarian relative weight and mature egg size with age has been revealed

Ecophysiological indicators of the state of animal populations exposed to damaging factors

Autor: M. I. Shatunovskii, S. A. Shilova

Publikováno v: Russian Journal of Ecology. 36:27-32

Indices of abundance and reproduction rate are considered in some groups of aquatic and terrestrial vertebrates from the zones of technogenic disasters. Upon a critical population decline caused by external destructive factors, such as emissions of a
