Theories and Models in Biogeography
This quiz covers the various theories and models used in biogeography to explain the distribution of species and ecosystems across the globe.
Questions
Which theory proposes that the distribution of species is primarily determined by their ability to disperse and colonize new areas?
- Vicariance theory
- Dispersal theory
- Neutral theory
- Equilibrium theory
According to the theory of island biogeography, what is the relationship between the size of an island and the number of species it can support?
- Positive correlation
- Negative correlation
- No correlation
- U-shaped relationship
Which model attempts to explain the distribution of species along an environmental gradient, such as a mountain slope?
- Species-area relationship
- Niche theory
- Neutral theory
- Habitat suitability model
What is the central idea behind the theory of neutral theory of biodiversity?
- Species are distributed randomly across the landscape
- Species interactions play a major role in shaping species distributions
- Environmental factors determine the distribution of species
- Dispersal limitation is the primary driver of species distributions
Which theory suggests that the distribution of species is primarily determined by their evolutionary history and the vicariance events that have occurred over time?
- Dispersal theory
- Vicariance theory
- Neutral theory
- Equilibrium theory
What is the main assumption of the equilibrium theory of island biogeography?
- Species immigration and extinction rates are equal
- Species immigration and extinction rates are independent of population size
- Species immigration and extinction rates are influenced by environmental factors
- Species immigration and extinction rates are affected by dispersal limitation
Which model predicts that the distribution of species is determined by their ability to compete for resources and their tolerance to environmental conditions?
- Species-area relationship
