Решающим фактором гибели до 90 % мегафауны плейстоцена стала человеческая деятельность. В поддержку этого вывода автор приводит эмпирические аргументы, расчеты, а также концептуальные соображения. Катастрофы внешнего происхождения способны вызвать восстановительную активность, но не качественное развитие системы (каковое в данном случае достаточно очевидно). Чтобы исследовать механизм последовательных прогрессивных изменений на всех стадиях эволюции биосферы и антропосферы, разрабатывается междисциплинарная синергетическая модель, построенная на понятиях устойчивого неравновесия, антиэнтропийной активности и эндо-экзогенного кризиса. В статье изложены ключевые положения модели. По мнению автора, сравнительно с классическими версиями она не только более правдоподобна, но, более того, предпочтительна с нравственной и прагматической точек зрения. Human activity was the decisive factor in the extinction of up to 90 percent of the Pleistocene megafauna. To argue this conclusion, the author brings empirical arguments, calculations, and conceptual considerations. The catastrophes triggered by external factors can entail the disaster-recovery activity but not a qualitative development of the system (which is pretty obvious in this case). A cross-disciplinary synergetic (chaos theory) pattern has been developed to explain the mechanism of consecutive progressive changes at all stages of the evolution of biosphere and anthroposphere. The pattern is built on the concepts of sustainable non-equilibrium, anti-entropy activity and endo-exogenous crisis (the one provoked by the system’s own activity). The article sets out the key constructs of the pattern. In the author’s view, this pattern not only is more verisimilar than the classical versions but is besides preferable within ethical and pragmatic perspectives.

The research goal is to study the correlation between indices of variational pulsometry, entropy of heart rate, temporal and spectral analyses and heart rate variability in healthy patients and patients with coronary heart disease. Materials. Of the study are indicators of variational pulsometry and temporal and spectral analyses from 111 patients with coronary heart disease and in 61 healthy individuals. Results. Most parameters of HRV correlated with each other. In healthy patients the greatest independence was characterized by Mo and LF/HF, in patients with coronary artery disease — only by LF/HF Significant correlation with SDNN RMSSD, TP, LF, HF was determined. Conclusion. The variational pulsometry, temporal and spectral analyses of HRV and entropy of heart rate provide HRV assessment. The indices are interdependent and indicate interchangeability of methods

Ostroumov S.A. Trends in modernizing the fundamental concept of ecosystem: self-repairing, self-cleaning, self-reforming, energy-saving, and labile biomachinery. - Ecological Studies, Hazards, Solutions, 2007, v. 12, p. 24-29. http://scipeople.com/publication/99066/; There are various concepts of ecosystem (e.g., Tansley, 1935; Alimov, 2000; Wetzel, 2001). Some authors consider an ecosystem to be a kind of organism or superorganism. Other authors consider it as a mechanism with a structure formed by a certain pattern of transfer of energy and matter. There are many types of ecosystems and possibly all of the various types of definition and vision are adequate in one or another specific situation. Recently, we published our own definition of an ecosystem that seems to be useful in some situations (Ostroumov, 2002c). The goal of this paper is to re-visit the formulations of some of the fundamental concepts underlying the functional organization of ecosystems. As our experience was mainly with aquatic organisms, we plan to use mainly the empirical data of studies of aquatic ecosystems and organisms. We hope that some part of our analysis will be applicable to both aquatic and terrestrial ecosystems. Our analysis leads to the following vision of an ecosystem that seems to be applicable to some natural and artificial aquatic ecosystems: we propose to see some of the aquatic ecosystems as self-repairing, self-cleaning, self-reshaping, energy-saving, and labile biomachinery. To support and substantiate this view, we locate some evidence from both our studies and the literature (see Table 1 in the article). The following issues were analyzed in the article: 1. Superorganism, mechanism or biomachinery? 2. Rigid structure or labile entity? We consider the aquatic ecosystem as a labile entity because…< see in the full text of the paper> 3.

Individual elements of ecosystems: independent species or groups of species? We developed a new concept of groups of species that we call ecological clusters (Ostroumov, 2004b). Ecological clusters are…< see in the full text of the paper> The article contribute to the evolution of ecology that is on the verge of revolution in conceptual terms, which is of importance in order to understand and use ecosystem services.
