Аннотация: The estimates of the carbon pool in the organic matter of gray soils of the southern taiga, the intensity of destruction of its components, and participation of the latter in the formation of the mineralized carbon flux to the atmosphere are presented for different stages of succession of deciduous (birch) and coniferous (fir) forests. The carbon pool varies from 139.7 to 292.7 t/ha. It is distributed between phytodetritus, mobile and stabile humus (32, 19, and 49%, respectively). The intensity of the mineralization carbon flux to the atmosphere amounts to 3.93-4.13 t C per year. Phytodetritus plays the main role in the formation of this flux. In the soils under the forests studied, 4-6% of the carbon flux are formed owing to mineralization of the newly formed soil humus. In birch forests, 2-6% (0.1-0.2% of the humus pool in the 0-20-cm layer) is the contribution to the flux due to mineralization of soil humus. In fir forests, the mineralized humus is compensated by humus substances synthesized in the process of humification during phytodetritus decomposition.

Аннотация: Consequences derived from the synthetic theory of evolution are in contradiction with facts. The theory affirms that the evolution rate depends on gene variability, intensity of recombination and press of natural selection. It means that fecund organisms with short life cycle have to evolve very quickly. In reality the quickest evolution is observed in mammals, for example in elephants. The theory predicts that evolution can not base only on mutation in the absence of recombination. But parthenogenetic and asexual species evolve very quick, and their variability is not less than that of sexual forms. Contrarily to the neo-Darwinism ideology, evolution takes place not only in constant environment and is often absent even in changing ecosystems. Reproductive isolation and fluctuations in population number are not sufficient conditions for the beginning of evolutionary changes. Numerous data show that the space of opportunities where evolving organisms can travel is constrained by morpho-functional and morpho-genetic factors more than it was considered by the synthetic theory of evolution. It means that evolution should be explained not only in terms of genome, but also using onthogenetic development of an organism and its interactions with environment. Application of organism-focused terminology is possible in the frame of the theory also based on the idea of natural selection, but providing different prognoses, sometimes opposite to the neo-Darwinistic ones.

Аннотация: It is generally accepted that animal heartbeat and lifespan are often inversely correlated, however, the relationship between productivity and longevity has not yet been described for trees growing under industrial and pre-industrial climates. Using 1768 annually resolved and absolutely dated ring width measurement series from living and dead conifers that grew in undisturbed, high-elevation sites in the Spanish Pyrenees and the Russian Altai over the past 2000 years, we test the hypothesis of grow fast-die young. We find maximum tree ages are significantly correlated with slow juvenile growth rates. We conclude, the interdependence between higher stem productivity, faster tree turnover, and shorter carbon residence time, reduces the capacity of forest ecosystems to store carbon under a climate warming-induced stimulation of tree growth at policy-relevant timescales.

Аннотация: A crucial issue in atmospheric studies on greenhouse gas content involves assessing the representativeness (footprint) having influence on their concentrations measured by tall towers. In this study, the Stochastic Time-Inverted Lagrangian Transport (STILT) model was used to estimate seasonal cumulative footprint climatology for greenhouse gases measurements obtained on the 301-meter-high Zotino Tall Tower Observation Facility (ZOTTO) for the growing seasons (May-September) from 2008 to 2012 (with the exception of 2011). Results showed that the ZOTTO seasonal concentration cumulative footprint climatology for four years reached 6.9x10(6) km(2) and the 75% cumulative footprints varied from 1.9 to 2.3x10(6) km(2). For the same period, the Russian Land Cover map based on MODIS data for 2014 was used to estimate the impact of land cover surrounding the ZOTTO tower on concentration measurements. The analysis showed that in the 75% seasonal cumulative footprint the largest area is occupied by bogs, followed (in decreasing order) by larch, mixed, light-coniferous evergreen forests, grassland, and by other classes. Furthermore, analysis of the contributions from individual cells making up a footprint showed that the largest influence on formation of greenhouse gas concentrations as recorded by ZOTTO comes from the types of vegetation growing in the immediate vicinity of the tall tower, namely bogs, mixed forests, and light and dark coniferous forest stands.
