# What is the difference between subpopulation and metapopulation?

## What is the difference between subpopulation and metapopulation?

A region may contain more than one population of any given species. A Metapopulation is the larger unit made up of a group of Subpopulations (local populations of one species).

How is metapopulation calculated?

We can express this mathematically:

1. I=pi⋅(1−f)(Eq. If most patches in the landscape are occupied, then the majority of the metapopulation can potentially go extinct.
2. E=pe⋅f(Eq. Combining equation 1 with the above equations, we get our first fully developed metapopulation model:
3. Δf=pi(1−f)−pef(Eq.

Is a metapopulation smaller than a population?

In Levins’ own words, it consists of “a population of populations”. A metapopulation is generally considered to consist of several distinct populations together with areas of suitable habitat which are currently unoccupied.

### How do you calculate colonization rate?

Colonization rate is the number of successful colonizations of unoccupied patches as a proportion of all available patches, and extinction rate is the proportion of patches becoming empty. Thus, dP/dt = C – E, or dP/dt = cP(1 – P) – eP, where c and e are the local immigration and extinction probabilities per patch.

What is the meaning of subpopulation?

Definition of subpopulation : an identifiable fraction or subdivision of a population.

What is a metapopulation example?

Metapopulation is a population in which individuals are spatially distributed in a habitat in two or more subpopulations. Populations of butterflies and coral-reef fishes are good examples of metapopulation .

#### What do you mean by metapopulation?

metapopulation, in ecology, a regional group of connected populations of a species.

What defines a metapopulation?

A metapopulation is a set of local populations within some larger area, where migration from one population to another is possible. A patch is a continuous area with all requisites for the persistence of a local population. It is separated from other patches by unsuitable habitat.

What is colonization rate?

Colonisation or colonization (λ) is the process in biology by which a species spreads to new areas. Colonisation often refers to successful immigration where a population becomes integrated into a community, having resisted initial local extinction.

## What is the relationship between colonization and extinction rate?

Relationships between colonization and extinction rates with time after fragmentation. Extinction rates did not vary with time (F 1,55 = 0.07, P = 0.78) or isolation (F 2,56 = 0.93, P = 0.40). Colonization rates decreased through time (F 1,56 = 3.87, P = 0.054), but did not vary with isolation (F 2,56 = 0.81, P = 0.45)

What is subpopulation example?

The definition of a subpopulation is a specific portion or part of a larger population. An example of a subpopulation is the population of women among the population as a whole. noun.

What is a metapopulation?

A metapopulation is a population of populations, or a group of groups, that is made up of the same species. Each subpopulation, or subgroup, is separated from all other subpopulations, but movement of individuals from one population to another occurs regularly. Are you a student or a teacher?

### What is a subpopulation?

What happens to metapopulation when a population goes extinct?

Some subpopulations might go extinct, but the metapopulation persists and can recolonize empty patches an equilibrium is reached which balances local extinction and recolonization

What is the equilibrium fraction occupied in a metapopulation?

If the rates ε and c remain constant with time, it follows that in a metapopulation with a large number of local populations, the fraction occupied will reach an approximate equilibrium at the value 1 − ϵ / c, provided c > ε, because at this value extinction is balanced with recolonization.
