Educational Model: Effect of Heat Quantity on Development of Poikilothermic Organisms

This model is a component of the IUMC (Innovative Educational and Methodological Complex) "Ecology: Constructing the Biosphere", developed in 2008 by D. A. Shabanov, A. G. Kozlenko, and M. A. Kravchenko by order of the NTFP (National Training Foundation) of the Russian Federation (more about this project is in the article "Innovation and Reality"; reasons why this complex is not used are briefly described in the column "Textbooks: Straight into the Day After Tomorrow"). This model is posted here for educational use. The model explains the concept of effective temperatures. The theoretical material related to the model is in the section "Concept of Effective Temperatures" of the manual "Ecology: Biology of Interactions". Instructions for working with the model are located at the bottom of its window; if they do not fit, they can be scrolled with the arrows on the right. To begin, click the splash window. Then drag table columns from the right side into the left part of the working area, where required graphs are built. Task statement and workflow are opened by corresponding buttons. Some tasks that can be solved while working with the model: 1. Study the effect of temperature on development duration in poikilothermic animals. Determine regularities using the clawed frog as an example. Using this knowledge, independently determine the development time of turtle eggs at a given temperature. 2. Determine whether the concept of effective temperatures is applicable to all poikilothermic animals and all developmental conditions.
