The leading role of the temperature effect in the spatial distribution and structural and functional characteristics of aquatic invertebrate populations is shown. During abrupt changes in temperature, the process of their physiological adaptation reveals itself in the mobilization of protective functions of the organism and is characterized by horizontal and vertical migrations, metabolic changes, and variety of adaptation strategies to changes in abiotic factors. The novelty of this work consists as well in the study of the structural and functional characteristics of the genome of natural and model populations of the invertebrates, which is allowed to predict critical temperature levels. It has been demonstrated that the excess of aberrant cells rate above 10% limits reproducibility of Gammaridae populations. The accumulation of emerging contaminants (xenobiotic organic substances) in various components of the water ecosystems of Ukraine has been established for the first time in Ukraine. A pilot system for assessing the toxicity, bioavailability and migration ability of toxicity substances has been developed. Product Description popup.authors Крот Ю.Г.
