Case Studies in Experimental Design: Investigating Predator Effects on Evolution of Prey

These flashcards cover key vocabulary and concepts from the lecture on the experimental design regarding predator effects on the evolution of prey, specifically focusing on schooling behavior in guppies.

Schooling in fish

A behavior that may serve as an adaptation to avoid predation.

Guppies

A species of fish studied in relation to their schooling behavior as an antipredator adaptation.

Cichlid fish

A type of predator fish used in the study to assess guppies' schooling behavior.

Adaptive value of schooling

The benefit of schooling behavior in guppies to enhance survival against predators.

Natural Selection

The process through which behavioral changes can occur in response to environmental pressures over generations.

Transfer Experiment

A study design used to predict changes in guppy schooling behavior in different predator environments over generations.

Predator avoidance

A key reason for the evolution of schooling in prey species.

Experimental Design

The framework used to test hypotheses in the study on elocution of guppy schooling.

Control group

A group in an experiment that does not experience the experimental treatment, used for comparison.

Replicates

Multiple trials or samples in an experiment to ensure validity of results.

Genetic drift

A mechanism of evolution that can affect traits like schooling if not controlled.
