Species Interactions and Competition

These flashcards cover key concepts related to species interactions, competition, and ecological principles discussed in the lecture.

Coevolution

The process where two or more species influence each other's evolutionary trajectory.

Diffuse Coevolution

Coevolution that involves a network of species interactions rather than isolated pairs.

Urban Ecology

The study of the ecological relationships of organisms within urban environments.

Lotka-Volterra Model

A mathematical model that describes the outcomes of species interactions on population size.

Competition Coefficients (α and β)

Values representing the per capita effect of one species on another's population.

Competitive Exclusion Principle

The principle stating that competitors with identical ecological niches cannot coexist.

Nonresource Factors

Factors outside of resource competition that can influence species interactions, such as temperature.

Habitat Loss

The primary cause of population decline in urban ecology, often due to human activities.

TTX-resistant Phenotype

A trait of some garter snakes that allows them to survive in areas where their prey, the newt, produces TTX.

Garter Snake and Taricha Newt

A specific example of coevolution where the predator-prey relationship drives adaptations.
