Abstract

The paper is devoted to computational modeling of biophysical processes with factors of heterogeneous adaptation. Plasticity and variability is the basis of evolution in natural biophysical systems. The complex of behavioral and biochemical adaptations allows the ancient populations of the Caspian Sea to efficiently use the limited resources and withstand the competition. During long-term simultaneous evolution in populations of Caspian organisms, a specific adaptation has appeared that is the strategy of survival optimal for physical conditions of the Caspian Sea. Interference in the existing hydrological systems of the region instantaneously deteriorated the advantages of the evolution strategy. An important form of adaptation for the Caspian Sea is the formation of subpopulation reproductively isolated groups that become units of species formation, accumulating the differences because of the reproductive isolation. In the paper we describe the method for analyzing the intrapopulation structure, where the groups with different reproductive behavior arose in the population. This is an aspect of the technical problem of the method for their introduction. A modified method of antigen differentiation developed by Yu.N. Perevaryukha (patent for invention RU 2253970) allowed determining the belonging of animal units to one of the reproductive groups of marine sturgeons by the differences in their antigens in the blood serum. It was shown that biophysical adaptation to long-term life in sweet water reflects in the presence in blood of specific proteins called the antigen markers. Immunochemical technologies immunodiffusion and electrophoresis are applied to study the markers of reproductive groups of Caspian sturgeons. The knowledge about the character of life cycle of groups isolated by their reproductive behavior and optimal temperature is necessary for artificial recovery of the populations. The data on the presence of two reproductive groups in starry sturgeon Acipencer stellatus are used to model the reproductive activity of the population. The information about the degree of intrapopulation differentiation allows improving the hybrid computational structure for the model of biophysical processes requiring the animal unit introduction technology; this structure was earlier proposed by us in Technical Physics. The model scenario explains the low efficiency of artificial release of sturgeon fish in the Caspian Sea. The procedure for reintroduction of sturgeons into the Caspian Sea must take into account the reproductive peculiarities of groups with different behavior. The considered problem is topical not only for populations of the Volga basin, but also for local populations in southern waters of the Caspian Sea of Iran and Azerbaijan.

基于适应差异免疫学分析的里海鲟鱼亚群繁殖过程杂交模型
本文致力于具有异质适应因素的生物物理过程的计算建模。可塑性和可变性是自然生物物理系统进化的基础。复杂的行为和生化适应使得里海的古代种群能够有效地利用有限的资源并经受住竞争。在里海生物种群的长期同步进化过程中,出现了一种特定的适应,这是里海物理条件下的最佳生存策略。对该地区现有水文系统的干扰立即削弱了进化战略的优势。里海的一种重要适应形式是形成生殖隔离的亚种群群体,这些群体成为物种形成的单位,积累因生殖隔离而产生的差异。本文描述了种群内部结构的分析方法,即种群中产生不同繁殖行为的群体。这是一个方面的技术问题,为他们介绍的方法。一种改良的抗原分化方法。Perevaryukha(发明专利RU 2253970)允许通过血清中抗原的差异来确定动物单位属于海洋鲟鱼的一个生殖群体。研究表明,对长期生活在甜水中的生物物理适应反映在血液中被称为抗原标记的特定蛋白质的存在。应用免疫化学技术、免疫扩散技术和电泳技术研究了里海鲟生殖类群的标记物。了解因繁殖行为和最佳温度而被隔离的种群的生命周期特征,对于种群的人工恢复是必要的。星形鲟鱼(Acipencer stellatus)中存在两个生殖群体的数据被用来模拟该种群的生殖活动。关于种群内分化程度的信息允许改进需要动物单位引入技术的生物物理过程模型的混合计算结构;这个结构是我们之前在《技术物理》中提出的。模型情景解释了里海人工放生鲟鱼的低效率。将鲟鱼重新引入里海的程序必须考虑到具有不同行为的群体的生殖特性。所考虑的问题不仅是伏尔加河流域居民的话题,也是伊朗和阿塞拜疆里海南部水域当地居民的话题。

期刊介绍: Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
