An inverse proportional correlation between the water mineralization in the lake Kulundinskoye and the fertility of sexually mature crustaceans Artemia sp. has been found which is expressed by a linear equation with a coefficient of correlation r =
A list comprising 181 species of lichens from 58 genera, 27 families, some of which are new for lichenflora of Siberia, Russia and Asia, based on the original data of 6 expeditions, is given. Most of these taxa belong to the genera Cladonia (28 species), Peltigera (16 species), Usnea (13 species), Hypogymnia (10 species), Lecanora (9 species), Bryoria (8 species). It is noted that 21 Pleistocene lichen-are relict species preserved in the Balgazin pine forest.

Spatial variations in the population of terrestrial vertebrates of West Siberia are described on the example on amphibians, birds and small mammals on the whole with respect to numbers and the amount of transformed energy. The force and commonness of constraint between the non-uniformity of communities and the environment are estimated. Non-coincidence of geobotanic landscape borders and territorial non-uniformity of various animal taxocenes is demonstrated.

A fibrous material composed of filamentary crystals of iron carbide Fe3C or metal iron encapsulated in graphite shells is synthesized. Combined investigation of the structure of the obtained material is performed by means of electron microscopy, powder X-ray diffractometry and Mössbauer spectroscopy. It is discovered that current-voltage characteristics of auto-emission properties of nanoparticles differ from the properties of pure carbon nano-tubes, which is explained by different adsorption characteristics of these materials.

Thermal decomposition of palladium acetylacetonate intercalated into fluorocarbon matrix is investigated by means of mass spectrometry. It is demonstrated that thermal decomposition occurs within a narrower temperature range, at higher rate and comes to its completion at lower temperature (~200 °C) than for the case of individual Pd(AA)2.

Iron (II) complexes with 1,2,4-triazoles are promising thermochromic materials. New complexes of iron (II) perrhenate and dodecahydro-closo-dodecaborate with 1,2,4-triazole (Htrz) and 4-amino-1,2,4-triazole (NH2trz) of the composition FeL3An ×mH2O (n = 1, 2; m = 4, 5) are synthesized and investigated. The compounds are studied by means of magneto-chemistry, XPA, electron and IR spectroscopy. Magnetochemical data show that the complexes possess 1A1 <=> 5T2 spin transition. The spin transition is accompanied by thermo-chromism (change of colour from pink to white).
