Data on the study of morphometric parameters of medicinal plants such as Hyssopus offi cinalis L. and Nepeta pannonica L., which are part of the collection of medicinal plants of the Botanical Garden of the Orеnburg State University, are presented. It was found that the studied species successfully adapt to new growing conditions, since the parameters of morphometry vary within the medium to very high levels of variability. However, Nepeta pannonica L.

The purposeful studies of communities of small mammals (insectivores and rodents) on the left bank of the middle Ob within the Khanty-Mansi Autonomous Okrug – Ugra (Khanty-Mansiysk, Nefteyugansk, Surgut and Nizhnevartovsk districts) were carried out for the fi rst time from 2011 to 2020. Animal counts were carried out both in transformed and specially protected natural areas.

In 1949 S. S. Khokhlov (one of the founders of the Russian scientifi c school on the problem of apomixes) proved the original conception of the progressive evolutionary role of apomixis. He contended that the basic direction of the reproductive system evolution in angiosperms is a gradual failure of sex reproduction and transition to apomixis. This hypothesis was heavily criticized and called a “scientist’s fantasy”. In the second half of the 20th century the discovery of recombination repair led to a reassessment of the role of meiosis in the evolution.
