Ecology: the biology of interaction. VII-06. Approximation of data on global human population growth using various models
Яка математична закономірність найкраще описує зростання кількості представників нашого виду на Землі? Для цього можна використати оцінки чисельності людства на різних етапах своєї історії. Звісно, ці оцінки не є абсолютно точними, але це — найкраще, що у нас є, і …
Ecology: Biology of Interactions. VII-05. The Preconditions-and-Consequences Model: Simpson's Paradox and the Evolution of Altruism
The "Simpson's Paradox" model is an example of a "preconditions-and-consequences model" that tests the assumption of whether certain preconditions are sufficient for the emergence of a given property in the system under study. This model seeks an answer to the …
Ecology: Biology of Interaction. VII-04. Some Types of R-Models in Population Ecology: Their Purpose and Structure
Why does the sun appear in the sky every morning and disappear every evening? Different answers to this question represent different models. One of the oldest models known to us, approximately five thousand years old, was created in Heliopolis, Egypt. …
Ecology: the Biology of Interaction. VII-03. Arithmetic and Geometric Growth
What is distinctive about the growth of organism numbers as a result of reproduction? Can a growing population avert a Malthusian catastrophe? In this and the two preceding sections there is sufficient information to begin searching for answers to these …
Ecology: The Biology of Interactions. VII-02. Introduction to R Properties Through Simple Examples
This section discusses the use of the R Markdown text markup language and the code chunks (code inserts) it provides for describing work with R. Basic information is then presented on vectors in R, their creation and indexing, the use …
Ecology: Biology of Interaction. VII-01. First Steps in Using RStudio
Since 2024, the authors have been adding to the ecology course explanations of the use of simulation modelling for better mastery of course materials. This page presents an introductory description of the features of the R language and a beginner-oriented …
