2. How does environmental gradient affect the distribution of species?
3. How do environmental factors affect the distribution and abundance of species?
4. What determines distribution and abundance of species?
5. What is the relative abundance of each species in a community?
6. What do you mean by relative abundance?

What does relative abundance reveal about an ecosystem?

The relative abundance of each species is more evenly distributed than Community 1. While both communities have the same species richness, Community 1 would have greater diversity due to the relative abundance of each species present.

How does environmental gradient affect the distribution of species?

As a result of a change in an environmental gradient, many species and life history traits such as: species abundance, population density, morphology, primary productivity, predation, and local adaptation may experience a change of greater or lesser magnitude.

How do environmental factors affect the distribution and abundance of species?

Both physical (temperature, rainfall) and biotic (predators, competitors) factors may limit the survival and reproduction of a species, and hence its local density and geographic distribution.

What determines distribution and abundance of species?

Abiotic and biotic features can interact to determine distribution and abundance. Some species distributions depend on disturbance—events that kill or damage some individuals, creating opportunities for other individuals to grow and reproduce. Example: Some species persist only where there are periodic fires.

What is the relative abundance of each species in a community?

Species abundance is the number of individuals per species, and relative abundance refers to the evenness of distribution of individuals among species in a community. Two communities may be equally rich in species but differ in relative abundance.

What do you mean by relative abundance?

Relative abundance is the percent composition of an organism of a particular kind relative to the total number of organisms in the area. Relative species abundances tend to conform to specific patterns that are among the best-known and most-studied patterns in macroecology.
