- Metapopulation:
- The concept of metapopulation is a fundamental ecological idea that describes how populations of a species are connected within a region, and how they are influenced by local births, deaths, immigrations, and emigrations. The structure of metapopulations varies among species and can have significant implications for the survival and persistence of these populations.
- Features of Metapopulation:
- Population Dynamics: Each population within a metapopulation is subject to changes in population size due to births, deaths, immigration (individuals moving into a population), and emigration (individuals leaving a population). Additionally, local populations may emerge and disappear over time.
- Local Population Vulnerability: When the numbers of individuals in local populations are low, they become vulnerable to extinction. Extinction events of local populations are not uncommon in some species.
- Regional Persistence: The regional survival of species is often dependent on the existence of a metapopulation. Even if some local populations go extinct, the species can persist at the regional level. Hence option (c) is the correct answer.
- Source-Satellite Structure: Metapopulations can have various structures. In some species, one stable source population serves as the supplier of individuals to less stable satellite populations. For example, the checkerspot butterfly in California has a source population surrounded by smaller satellite populations.
- Shift in Source Populations: In other species, the source population that provides recruits can shift over time. Local populations may take turns acting as stable sources depending on changing conditions, such as disease outbreaks or deteriorating environments.

Metapopulation Concept in Ecology
The metapopulation concept in ecology refers to a population of a species that is interconnected and consists of several smaller subpopulations that are spatially separated but can interact with each other. This concept was first proposed by ecologist Richard Levins in 1969.
Key Points:
- Interconnected Populations: In a metapopulation, the subpopulations are connected by occasional migration or dispersal of individuals between them. This connectivity allows for genetic exchange and the potential rescue of smaller populations from extinction.
- Rescue Effect: One of the key aspects of the metapopulation concept is the idea of the "rescue effect." When a subpopulation goes extinct, individuals from other subpopulations can recolonize the vacant habitat, preventing the overall extinction of the species.
- Dynamic Nature: Metapopulations are dynamic systems that are constantly changing in response to factors such as habitat loss, environmental disturbances, and changes in population size. Subpopulations can grow, decline, or go extinct over time.
- Conservation Implications: Understanding metapopulation dynamics is crucial for conservation efforts, as it highlights the importance of maintaining connectivity between subpopulations to ensure the long-term survival of a species. Conservation strategies often focus on preserving habitat corridors and promoting landscape connectivity.
In conclusion, the metapopulation concept in ecology emphasizes the interconnectedness of populations and the importance of maintaining viable subpopulations to prevent species extinction. By studying metapopulations, ecologists can gain insights into population dynamics, genetic diversity, and conservation strategies.
