  1. 1-139-S-PlantsVsHerbivores

    08 Mar 2021 | | Contributor(s):: Mary Vanderschoot

    In a recent study of plants and herbivores on an island in the North Sea, ecologists made a surprising observation: Instead of more vegetation resulting in more grazers, more vegetation resulted in fewer grazers. Consequently, the ecologists hypothesized that, as the vegetation grew more dense,...

  2. 1-137-S-SheepGraze

    03 Mar 2021 | | Contributor(s):: Mary Vanderschoot

    One of the most well-known mathematical models in ecology is the Lotka-Volterra predator-prey system of differential equations. Initially, this model was used to analyze interactions between two animal populations. But ecologists discovered that it could also be applied to plant (`prey') and...
