Stability studies within organisms

Biocomplexity is a characteristic feature of all systems of the environment connected with life. The ways in which this is manifested are studied within the framework of the theory of stability and vitality of ecosystems. Note that biocomplexity includes indicators of the extent to which interacting systems modify each other, and this means that biocomplexity should be studied by considering both the spatial and biological levels of its organization. The difficulty of this problem is explained by the complicated behavior of the object under study, especially when the human factor is considered, due to which the number of stress situations in the environment is constantly growing. Within this study the Arctic systems are considered as NSS sub-systems. 

A reevaluation of molecular structure of humic substances based on data obtained primarily from nuclear magnetic resonance spectroscopy, X-ray absorption near-edge structure spectroscopy, electrospray ionization-mass spectrometry, and pyrolysis studies was presented by Sutton and Sposito (2005). The authors consider that humic substances are collections of diverse, relatively low molecular mass components forming dynamic associations stabilized by hydrophobic interactions and hydrogen bonds. These associations are capable of organizing into micellar structures in suitable aqueous environments. Humic components display contrasting molecular motional behavior and may be spatially segregated on a scale of nanometers. Within this new structural context, these components comprise any molecules...
