A metapopulation is a group of populations of the same species connected by dispersal, allowing for gene flow and the exchange of individuals between populations.

Source populations have higher birth rates and lower death rates than sink populations, resulting in a net positive population growth rate, while sink populations have lower birth rates and higher death rates, leading to a net negative population growth rate.

Habitat quality affects the carrying capacity of populations by determining the amount of resources available, it affects the dispersal rates of individuals by influencing their movement patterns, and it affects the extinction rates of populations by determining their vulnerability to environmental disturbances.

Habitat fragmentation reduces connectivity between populations by creating barriers to dispersal, making it more difficult for individuals to move between populations.

Dispersal plays a crucial role in metapopulation dynamics by allowing for the colonization of new habitats, the recolonization of habitats after local extinctions, and the exchange of genetic material between populations, promoting genetic diversity and reducing the risk of inbreeding.

Metapopulation dynamics can contribute to conservation biology by helping identify and prioritize areas for conservation, designing and implementing conservation strategies, and monitoring the effectiveness of conservation efforts, ultimately aiding in the preservation of biodiversity.

Predation is not typically considered a factor that directly affects the dynamics of a metapopulation, although it can indirectly influence population sizes and dispersal patterns.

The probability of extinction for a local population in a metapopulation is influenced by a combination of factors, including the size of the local population, the connectivity between local populations, and the environmental conditions.

The minimum viable population size for a metapopulation is not a fixed value and can vary depending on factors such as habitat quality, dispersal rates, and environmental conditions.

A metapopulation of birds in an urban area can be an example of a source-sink metapopulation, where some urban areas act as sources (with high-quality habitat and positive population growth) and others act as sinks (with low-quality habitat and negative population growth).

Corridors play a crucial role in metapopulation dynamics by facilitating dispersal between populations, providing habitat for species, and reducing the risk of extinction by connecting isolated populations and allowing for gene flow.

Habitat fragmentation is not a management strategy for conserving metapopulations, as it reduces connectivity and increases the risk of extinction for local populations.

Metapopulation dynamics can promote genetic diversity by facilitating gene flow between populations, reducing the risk of genetic drift and inbreeding, and allowing for the exchange of genetic material.

Monarch butterflies exhibit metapopulation dynamics, as their populations are distributed across a wide geographic range and are connected by dispersal, forming a metapopulation structure.

Environmental stochasticity, such as natural disasters or climate fluctuations, can cause local extinctions, prevent colonization of new habitats, and increase dispersal rates, influencing the dynamics of metapopulations.
