Ecosystems of protected area of the Natural Park “Medeu”

The article presents the results of mapping ecosystems of the protected area of the Natural Park “Medeu”,located on the northern slope of the Trans-Ili Alatau mountain range. The map of ecosystems and a legend has beencompiled. The legend contains 13 numbers. The largest sections of the legend are the natural ecosystems of the protectedarea and the natural-anthropogenic ecosystems of the buffer zone and the zone of limited economic activity. The habitatsof species from Red Data book of Kazakhstan that form communities (Malus sieversii (Ledeb.) M. Roem., Armeniacavulgaris Lam., Celtis australis subsp. caucasica (Willd.) C. C. Towns. identified, and their brief characteristics are given.

Фитоценотическая роль культур в севообороте

The mountainous zone is the place of origin of drinking and medicinal waters, as well as the cultivation of economically pure food products and the production of seeds of agricultural crops of the highest reproduction. To preserve natural and anthropogenic ecosystems and landscapes from pollution in mountain conditions, weed control is carried out by a combination of biological, agrotechnical and mechanical methods, eliminating the need for the use of herbicides. In this regard, the phytocenotic role of agricultural crops in crop rotations is of great importance.

Contribution to the Knowledge of Mycobiota of the Wielkopolski National Park (W Poland)

The Wielkopolski National Park is located in western Poland, near Poznań City. Its unique postglacial landforms are covered with various (semi)natural and anthropogenic ecosystems. The mycobiota of this Park has been studied for 90 years; however, current state knowledge is still insufficient. In 2018, a few-year- long project on the chorology, richness, and diversity of fungal biota of this area was started. In the first year, 312 taxa of macromycetes were found. Among them, 140 taxa were new for the biota of the Wielkopolski National Park. Five species (<em>Botryobasidium robustius</em>, <em>Hebeloma subtortum</em>, <em>Leccinum brunneogriseolum</em>, <em>Pachyella violaceonigra</em>, and <em>Sistotrema athelioides</em>) were new for Poland, and 26 taxa were new for the Wielkopolska region.

An overview of waste collection systems in anthropogenic ecosystems

The paper discusses recent research and publications in Russian and foreign publications that study the application of solid municipal waste management systems in anthropogenic ecosystems. The analysis of the use of Russian and foreign digital technologies and Internet resources that manage municipal waste is carried out. The analysis of general aspects of solid waste management theory has shown that there is a problem of solid urban waste management (SWM) in various countries. Four main areas of waste management have been identified: collection and logistics, the use of machines and plants for waste treatment, business models and the use of data collection, storage, and processing tools. Logistics management of solid waste is a very complex and important job for any municipal corporation around the world. The use of various technologies and plants for waste treatment and sorting requires investment in each specific plant, but in the end it will help to optimize the management of solid waste. Innovative business models for solving environmental problems of waste accumulation require government incentives in the form of subsidies or tax incentives. The analysis of data collection, storage and processing tools that regulated waste flows revealed a promising possibility of using GIS technologies, the Internet of things and blockchain technologies for waste management. The paper proposes a new web-GIS technology (web application Garbage collector) for collecting large amounts of statistical data on the state of container sites in the city. Using the app will help you organize a waste management system within a locality by citizens, regardless of the management companies, together with the municipal authorities.

Catabolism of organophosphonates: biochemistry, physiology and interactions of degrading bacteria in the environment

The major contribution of microorganisms in metabolism of natural and synthetic phosphonates, the biochemical bases of these processes and possible interactions between degrading bacteria in natural and anthropogenic ecosystems are presented in the light of the recent data on significant role of reduced phosphorus compounds in the biosphere. Special emphasis is placed on C-P lyase and phosphonatase which are pivotal enzyme systems for catabolism of both natural and synthetic phosphonates. Modern data on structure, diversity, regulation and physiological role of both enzymes are reviewed and discussed.
