The Lotka–Volterra equations, also known as the Lotka–Volterra predator–prey model, are a pair of first-order nonlinear differential equations, frequently used to describe the dynamics of …

A graph showing the abundance of a predator, B. calyciflorus (zooplankton), in red, and its prey, Monoraphidium minutum (unicellular green algae), in green. Note how the spikes in predator …

Students use a small graphing simulation to show how populations and predators change when you adjust their reproductive rates. Several outcomes occur depending on the input numbers.

In the classic Lotka-Volterra model of predator-prey dynamics, both predators and prey are modeled using a modified version of the equation for exponential growth, so neither population …

It was developed independently by Alfred Lotka and Vito Volterra in the 1920's, and is characterized by oscillations in the population size of both predator and prey, with the peak of …

This graph lets you explore the interaction between a predator and its prey. This could represent populations of foxes and rabbits, for example, or wolves and deer, or sharks and tuna, and so on.

Use the menu (top left) to navigate between models. Use sliders to change parameter values, and then click on start point in isocline diagram (top left graph) to run a model. Click isocline figure …

Nov 24, 2024 · Predator-prey graphs are visual representations of the fluctuations in predator and prey populations over time. They typically consist of two lines: one for the predator population …

Feb 27, 2025 · Analyze predator prey graphs to understand ecosystem dynamics, species interactions, and population cycles, including Lotka-Volterra models and predator-prey …

Students will analyze graphs of hare and lynx populations produced by the predator-prey spreadsheet model. This analysis will provide students with the opportunity to observe the …
