Im working on a Ecology question and need guidance to help me study.
Hi there,
Could you please use POPULUS to answer these questions? POPULUS is a free application that graph two compete species. The link to download POPULUS provide in this page. Please answer it from your observation, do not use google to answer it. However, you can use google to understand some definition.
Some steps help you to know how to start on POPULUS:
At the main menu in Populus, choose “Multi-Species Interactions”. On the multi-species interactions menu choose “Lotka-Volterra Competition”. This will get you into the model that we will use this week. In case you need a refresher about the material, the Help Menu in Populus opens a pdf file that reviews ecological concepts and processes modeled by the program.
The Lotka-Volterra model of competition is a simple extension of the logistic model of intraspecific competition and population growth, with the added complications of equations for two (or more) species, and the addition of interspecific competition coefficients. In the two species case Populus designates the competition coefficients as a and b, where a is the effect of species 2 on species 1, and b is the effect of species 1 on species 2. Note that in the book the equivalent terminology for a is ? 12 and for b is ? 21. The remaining terminology (r, K, N) is the same as in the logistic model.
