What ecosystems would you expect to have low species richness?
On the other hand, the polar and desert regions have a low species richness due to its abiotic conditions. These areas have extreme temperatures, and limited access to sunlight, water, and nutrients; hence, decreasing the productivity and biodiversity of the ecosystem.
Does a diverse ecosystem have low species richness?
An aquarium with many different species of animals, but very few individuals of each species confined to a small space is an example. Likewise, you could have an ecosystem with high abundance, low species richness and therefore, low species diversity. An Oak forest is an example of this.
What causes low species richness?
Several factors affect small-scale species richness, including geographic factors such as the regional species pool, dispersal distance and ease of dispersal, biological factors such as competition, facilitation, and predation as well as environmental factors such as resource availability, environmental heterogeneity …
Can an ecosystem have high species richness and low species evenness or vice versa?
Why is it important to measure “baseline” species richness and evenness in an ecosystem? … Species evenness because an ecosystem can have as many species as it can hold but if the species are mostly the same species then there is not any biodiversity in the ecosystem which can lead to die offs and disease.
What is in the ecosystem?
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. … Abiotic factors include rocks, temperature, and humidity.
What is ecosystem diversity?
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.
What are the main factors in ecosystem diversity?
Broadly speaking, the diversity of an ecosystem is dependent on the physical characteristics of the environment, the diversity of species present, and the interactions that the species have with each other and with the environment.
What is species richness example?
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.
