Species richness is the number of species. Species diversity is a measurement of species richness combined with evenness, meaning it takes into account not only how many species are present but also how evenly distributed the numbers of each species are.
For example, if two communities both have five species, species richness would be five for both communities. If the first community had individuals and 80 of them were all one species, this would not be a community with a very even distribution. If the second community had individuals, with 20 individuals belonging to each of the five species, this community would be more evenly distributed. Because it was more evenly distributed, community two would have a greater species diversity.
Genetic Diversity: Genetic diversity is a trait of the species. Species Diversity: Species diversity is a trait of the community. Genetic Diversity: Genetic diversity promotes the adaptability and distribution of a particular species in diverse habitats. Species Diversity: Species diversity promotes the biotic interactions and stability of the community.
Genetic diversity and species diversity are two types of biodiversity. Genetic diversity is the variation of genes within a particular species. Species diversity is the variation of species within a particular area. The main difference between genetic diversity and species diversity is the type of variation of each type of diversity.

In order to conserve species diversity, natural resource management and habitat protection are vital. Ecosystem Diversity can be defined as the variety of different habitats, communities and ecological processes. A biological community is defined by the species that occupy a particular area and the interactions between those species. A biological community together with its associated physical environment is termed an ecosystem. Partly due to its complexity, biodiversity can be extremely difficult to measure.
However, there are a few key indicators of biodiversity that we can accurately and efficiently monitor. For coral reefs these indicators include: seafloor diversity, seagrass, mangroves, seabirds, species of conservation concern and species richness and community structure of hard corals on the GBR.

Nature Education Knowledge 3 10 Ecological communities are associations of species that co-occur in the same location at the same time. Community ecology is a field that examines the effects of abiotic and biotic features on community or assemblage structure.
