Results of the first test.
Biotechnologists! Prepare for Testing!
Models and links for preparing for the test on Topic 1.
Ecology 2019. Course Results
The 2019 ecology course has been completed. Most students receive credit based on semester work results. Here are the results and an explanation of how points will be adjusted.
Ecology-2019. Test on Topic IV (Human Ecology)
Results of the final test in the 2019 ecology course.
Ecology-2019. Test on Topic II (Ecosystems and Populations)
Results of the penultimate ecology test. The final test, on human ecology, is scheduled for Tuesday, May 21, during the 3rd class period.
Ecology-2019. Test on Topic I (Biosystems and Biospherology)
Results of the first test. The next one, on Topic II (Autecology) – April 16. Models for preparing for this test – here
Ecology: Biology of Interactions. II-09. Biogeochemical Cycle of Phosphorus
The phosphorus cycle is much less regulated than the just-considered carbon and nitrogen cycles because phosphorus lacks an exchange reservoir in the atmosphere. Phosphorus is the primary element that controls the productivity of aquatic communities. In the experiment with pond …
Ecology: the biology of interaction. II-08. Biogeochemical cycle of Sulfur
Sulfur — a relatively abundant (fifteenth by chemical abundance) element in the Earth's crust, occurring in various oxidation states. It is a necessary component of proteins (0.8-2.4%), entering into their composition in the form of sulfhydryl groups (-SH) and disulfide …
Ecology: Biology of Interaction. II-07. Biogeochemical Cycle of Nitrogen
The BGC cycle of Nitrogen is more complex than the Carbon cycle. It is also extremely important for living organisms. Although nitrogen is more abundant in the atmosphere than other gases, its incorporation into living matter is a far more …
Ecology: Biology of Interaction. II-06. Biogeochemical Cycle of Carbon
Carbon is the foundation of organic compounds, and therefore the Carbon cycle is of particular significance for living organisms. The most important feature of this cycle is the presence of CO2 reserves — carbon dioxide — in the atmosphere, from …
Ecology: Biology of Interactions. II-05. Energy Sources for Biogeochemical Cycles
Movement of elements in the biosphere is maintained by three main energy sources (“drive belts” of biogeochemical cycles): solar energy transformed by hydrosphere and atmosphere in the hydrological cycle; solar energy stored in organic matter by photosynthesis; and chthonic (internal …
Ecology: biology of interaction. II-04. Biogeochemical cycles
Biogeochemical cycle (BGC-cycle) refers to a relatively closed set of pathways for the transformation and movement of substances through living organisms and their environment. Biogeochemical cycles are called this because both biological and geochemical processes are involved in their functioning. …
Ecology: biology of interaction. II-03. Gaia hypothesis (metaphor)
In 1972, James Lovelock and Lynn Margulis proposed the so-called «Gaia hypothesis» — the conception of Earth as a superorganism that maintains its homeostasis. As Lovelock later indicated, he and Margulis independently arrived at ideas previously expressed by James Hutton …
Ecology: The Biology of Interaction. Appendix II. Questions for Credit or Examination
Questions included in examination tickets for the credit test or examination in ecology (bioecology). The questions appear in the tickets in a different order from that given here.
Ecology: biology of interaction. II-02. Noosphere
Probably, the main author of the concept «noosphere» was Pierre Teilhard de Chardin, a French priest and evolutionary scientist. Teilhard was a member of the Jesuit order, and therefore the ideas he publicly expressed were limited by the order's discipline. …
Ecology: Biology of Interaction. I-11. (Supplement) The Scientific Method
The operation of the hypothetico-deductive model of scientific cognition can be described by the following algorithm: 1. Search for inconsistencies in the application of the scientific system of concepts (the model of reality constructed by science) to explain available data; …
Next Ecology Retake
Dear third-year students! Those of you who did not pass the ecology credit can do so on Wednesday, January 3, at 14:00.
Ecology-2017. Overall Results
The results of the 2017 ecology course are in. The credit examination will be held according to the following schedule: 4th period on Monday, December 18; 4th period on Tuesday, December 19; 3rd period on Wednesday, December 20; 4th period …
