Applying songbird population dynamics models to conservation biology needs

A. L. Podolsky
Proper understanding of the reproductive biology traits and population dynamics patterns of declining songbird species is crucial for ensuring their effective protection and recovery. Metapopulation dynamics may cause the extinction of local populations in some landscape patches regardless of the habitat quality and undertaken conservation measures. At the same time, the source-sink type of the population dynamics could saturate lower quality habitat patches with dispersing individuals from the population sources. Hence, poorer quality habitats presumed...

M. A. Kanis’kin, A. A. Izosimov, V. A. Terekhova, O. S. Yakimenko & M. A. Pukalchik
Influence of some humic products (HP) on ecotoxicity of model soils mixtures (MS) with phosphogypsum (PG) is investigated. Using the standardized test-cultures (Daphnia magna, Scenedesmus quadricauda, Sinapis alba) it is established that humates originated from peat – Pe-FlexK and from coal – BC-EnK reduce toxicity of MS and FG mixtures. Detoxication activities of HP decrease at increasing their concentrations in mixtures from 0.005% to 0.02% and increase the share of phosphogypsum from 3.3% to 7.5%.
