PPT-Theoretical Impacts of Habitat Fragmentation and Generalist Predation on Predator-Prey

Kelsey Vitense Current Challenges for Mathematical Modelling of Cyclic Populations Workshop at BIRS 111213 Outline Motivation Models Results Next steps Meadow Vole Many cyclic mammalian species undergo dramatic fluctuations in abundance in north but exhibit damped dynamics in south. Community Ecology:. Antagonism (part 2).. Antagonisms: . Prey and predator are differently motivated:. Whereas the prey runs for its life, the predator runs for a meal.. Or, when the predator loses it misses a meal; when the prey is defeated, it loses its life.. Predators. . Predators are animals that eat other animals for food.. Barn Owl. Mountain Lion. Predators are . carnivores. (animals that eat meat) or . omnivores . Intraguild predation. Presented by: Maria Vozzo, BIOL 7083. April 16, 2013. Mini-Biography. Education: .

Before you begin predict what will happen to the camouflage and visual acuity scores of the prey and predator over 10 generations. . Write . a hypothesis in your lab notebook.. Game set up. Winner takes all. Adaptive techniques predator. Keen eyesight, hearing, sense of smell and dentition suitable to killing prey.. Camouflage, which allows the predator to be concealed while hunting its prey.. Muzvondiwa J.V.. Outline. There . are a variety of . antipredator. adaptations, which suggests that predation is important in nature. Predator–prey models can explain many outcomes. Field data suggests that predators have a large impact on prey populations. . Taylor Drexinger. Lena Finkel. David Quinn. Caroline Wilkinson . Background. Schooling vs. Shoaling. How fish school.

Our simulation will consist of a game in which predators (students) with different size mouths (forceps) will compete to capture prey (beans) which vary in color. .
