Island Biogeography 🏝️

What is the study of rates of colonization and extinction of species on islands or other isolated areas called?

• Island biogeography

• Ecological succession

• Population dynamics

• Habitat fragmentation

What is habitat loss?

• The destruction or alteration of a natural habitat, leading to a decline in species populations.

• The increase in the number of species in a given area.

• The preservation of natural habitats to protect biodiversity.

• The introduction of new species into an ecosystem.

What is the role of camera traps in studying biodiversity?

• Camera traps are used to monitor wildlife populations and assess biodiversity in various ecosystems.

• Camera traps are primarily used for capturing high-quality images of landscapes.

• Camera traps are utilized to track weather patterns in different regions.

• Camera traps serve as a tool for measuring soil quality in agricultural areas.

What is biodiversity?

• The total number of species in a given area.

• The variety of life in the world or in a particular habitat or ecosystem.

• The study of ecosystems and their interactions.

• The process of evolution in different species.

What are provisioning services?

• Ecosystem services that provide direct benefits to humans, such as food, water, and raw materials.

• Ecosystem services that regulate climate and air quality.

• Ecosystem services that support nutrient cycling and soil formation.

• Ecosystem services that provide aesthetic and recreational benefits.

What is the relationship between biodiversity and ecosystem stability?

• Higher biodiversity generally leads to greater ecosystem stability and resilience to environmental changes.

• Biodiversity has no significant impact on ecosystem stability.

• Lower biodiversity increases ecosystem vulnerability to changes.

• Ecosystem stability is solely dependent on climate conditions, not biodiversity.

What is ecosystem service?

• The benefits that humans derive from ecosystems, including provisioning, regulating, cultural, and supporting services.

• A type of environmental policy aimed at protecting natural resources.

• A method of measuring biodiversity in an ecosystem.

• A financial incentive for conservation efforts.

What is a reduction in the genetic diversity of a population caused by a reduction in its size?

• Bottleneck effect

• Founder effect

• Genetic drift

• Natural selection

What is genetic drift?

• A mechanism of evolution that refers to random changes in the frequency of alleles in a population.

• A process that leads to the adaptation of species to their environment.

• A method of artificial selection used in agriculture.

• A theory that explains the inheritance of acquired characteristics.
