Contaminant exposure can vary between species but primary causes of it are often unclear. In order to estimate heavy metal intake of two sympatric passerines - Ficedula hypoleuca Pall. and Parus ater L. - we studied nestling diet and metal concentrations in prey invertebrates, near the Middle Ural copper smelter and in an unpolluted area. Diet of P. ater contained more Cu, Cd and Zn compared to...

Dobzhansky, Carol Madden, and to Mr. B. A. Spassky for their efficient help in carrying out the very laborious experiments and calculations. Professor Howard Levene and Mr. Timothy Prout have contributed some valuable advice concerning statistical problems. We wish also to acknowledge stimulating disoussion's with Professor I. Michael Lerner, who has dealt with the problem of "genetic homeostas...

We explored if breeding parameters and egg shell quality of an insectivorous passerine, pied flycatcher Ficedula hypoleuca, have fully recovered after c.a. 99% decrease in dust emissions from a non-ferrous smelter in the course of the 23 year study period. Some potentially important population characteristics (density, phenology, age) and environmental variables (habitat, inter-specific competi...

We consider the distribution of the intermediate filaments (IFs) in the retinal cells of the Pied flycatcher (Ficedula hypoleuca, Passeriformes, Aves) in the foveolar zone, which has the most specialized morphology, where the passerines have neither the rods nor the second-order neurons that service these rods, with only the single and double cones acting as photoreceptors. We report that singl...

Salvia is one of the famous genera of the family Lamiacea previously called Labiatae comprising about 800 species throughout the world [1]. Most of the members of this genus are known due to their biologically active chemical constituents specifically reported for anti-tumor activity [2]. A number of Salvia species are used in folk medicines. For example, S. cavaleriei is used for the treatment...
