Difference Between Biodiversity and Species Richness

Difference Between Biodiversity and Species Richness

The key difference between biodiversity and species richness is that biodiversity refers to the variety of life found in a specific place on Earth or the total variety of life on Earth while species richness refers to the number of different species represented in an ecological community, landscape or region.

How do species richness and species diversity differ quizlet?

Species richness is a count of the number of species in an area. Species diversity incorporates both species richness and the relative abundance of each species. Species diversity is a more accurate means of quantifying the diversity of species. Species richness is a count of the number of species in an area.

How does species richness affect biodiversity?

Species richness refers to the number of species in an area. ... 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.

What is the difference between species richness and species evenness?

What is the difference between species richness and species evenness? ... Species richness measures the number of different species while species evenness tells whether the ecosystem has a dominant species or has similar abundances of all species.

What is an example of species richness?

Species richness is the number of species within a community or area. For example, if we have two plots of lands, A and B, and plot A has twenty four species of plants and plot B has eighty four species of plants, plot B has higher species richness.

Why is species diversity important?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. ... A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

How do you calculate species richness?

Species richness is the number of species in a given area. To calculate species richness, you will count the number of cells below each vegetation type that contains a species name. The function =COUNTIF(range, "*") will calculate the total number of cells you highlight that contain any text.

Which ecosystem is richest in biodiversity?

Summary: Amazonia represents the quintessence of biodiversity – the richest ecosystem on earth. Yet a study by Smithsonian scientists, published this week in the journal Science, shows that differences in species composition of tropical forests are greater over distance in Panama than in Amazonia.

What are the two factors that affect species diversity?

The factors related to these patterns of small- scale species richness include (1) geographic factors such as scale of observation, available species pool and dispersal patterns, (2) biotic factors such as competition or predation and (3) abiotic environmental factors such as site resource availability, disturbance and ...

What are the 2 components of species diversity?

Components of species diversity: species richness and relative abundance.
