Ecology-2017. Results of the 2nd Test
The second test, autecology...
Ecology: Biology of Interaction. II-01. Biosphere
The biosphere is Earth’s shell transformed by the activity of living organisms. An alternative interpretation (biosphere as the shell of Earth within which living organisms occur, the “field of life existence” in V. I. Vernadsky’s terms) is much less useful. …
Ecology-2016. Second Topic
Results of the test on the second topic. A reminder about the test on the third topic — in the second class period on Monday, December 5!
Ecology-2015. Third module and seminars (the last step remains)
Almost complete results of the work within the ecology course. Only the last module remains...
Ecology: Biology of Interaction. I-15. (Supplement) Models as a Tool of (Self-)Deception
«The computer memory was loaded with a description of a chordate animal prototype analogous to the lancelet that has survived to the present day (A); the numbers at the bottom are the ‘genotype’ — a machine description of 24 traits …
Ecology: biology of interaction. I-12. (supplement) Universal properties of biosystems
Despite specificity of biosystems at different levels, a set of universal properties can be identified: ordered composition, hierarchy, metabolism, information continuity and variability, individuality, and capacity for reproduction/self-renewal across levels.
Ecology: biology of interaction. I-07. Properties of complex systems
The more integrated a system is, the harder its mosaic description becomes. A reductionist view is necessary but insufficient: emergent properties arise from interactions and cannot be fully inferred from isolated parts.
Ecology: biology of interaction. I-14. (supplement) Describing diversity of biosystems: classification, typology, ordination
Dynamic typology is based not only on analysis of an object’s observed state, but also on forecast (typically probabilistic) of its future dynamics. One path to its construction is analysis of phase space trajectories and stability basins.
Ecology: Biology of Interaction. I-08. Stability of Biosystems
A characteristic feature of regulation by the principle of negative feedback is that it leads to oscillations of the regulated variable. If the influence drives the biosystem beyond the limits of its regulation by negative feedback loops, it will transition …
Ecology: biology of interaction. I-06. Regulation of biosystems
Direct link — is the influence of a certain factor on the studied system (example: turning the steering wheel, the driver changes the direction of the car’s movement). Feedback — the dependence of the controlling influence on the state of …
Ecology: Biology of Interactions. I-03. Levels of Biosystem Organization
Biological systems are organized hierarchically, and at each level regulation is carried out using similar principles. In the late 20th century, the systems approach stemming from Ludwig von Bertalanffy gained development. It is based on the premise that systems built …
Ecology: The Biology of Interaction. I-02. History of Ecology
There is a view that ecology as a science might have been born at the end of the eighteenth or the beginning of the nineteenth century, owing to the work of Antoine Lavoisier. In 1792, Lavoisier presented a report «The …
Ecology: Biology of Interactions. I-04. Structure of Ecology and its Place Among the Branches of Biology
In this course, ecology is divided into general and special, and within general ecology branches are distinguished that correspond to different levels of biosystem organization.
Ecology: the Biology of Interactions. I-01. "Ecology" — What Is It?
The term «ecology» was coined by Haeckel from two Greek roots: oicos — home and logos — word, science. From the moment the concept of «ecology» was established, there has been an unbroken succession of researchers who interpreted it in …
Hoffmann et al, 2015. Genetic diversity and distribution patterns of diploid and polyploid hybrid water frog populations across Europe
An article was published in Molecular Ecology in which the author of this website also participated (as contributor of material). Unfortunately, access to the article is paid, so only the abstract is provided here. Hoffmann A., Plötner J., Pruvost N., …
Ecology: biology of interaction. Title and preface
With this page, the authors begin creating the Ukrainian version of the second edition of their ecology textbook. The work is organized as follows: the Russian text of the first edition was placed online at Batrachos.com, then gradually revised and …
Toward What Overarching Goal Should the School Education System Be Built? (a programmatic text, 2014)
The overarching goal of education in contemporary Ukraine has been lost. Revising printed or electronic textbooks without changing their concept will not lead to a change in the quality of education. Humankind is at a turning point in its history; …
Ecology, 2013. Result of the Autecology Module
This year, Module II (autecology) was taken first. The result was poor. Prepare well: you take Module I (biosystem properties and biospherology) from November 11 to 15!
Ecology, 2012. Results of Module III
Almost, almost... Soon there will also be results of the final module, but for now here are the results of Module III. Work!
