Examine each of the following types of organisms. Drag them into the correct order of succession - pioneer species at top and climax species at the
bottom.
= large hardwood trees, understory species, forest floor community
mosses, lichens
= small and medium size trees
grasses, shrubs
Fire creates disturbance in the temperate coniferous forest of the Pacific Northwest. Prior to the early 1900s,
patchy, moderately intense, and moderately frequent fires created intermediate amounts of disturbance.
Following the early 1900s, a policy of fire suppression greatly reduced fires, creating low disturbance. Today,
hotter, drier, longer summers are creating extremely large, intense, and frequent fires, which cause severe
disturbance. Which of the following most accurately describes how these levels of disturbance affect species
diversity?
O Low disturbance allows for the greatest species diversity, because all the organisms are allowed to thrive.
Severe disturbance allows for the greatest species diversity, because it facilitates colonization by r-selected species.
Moderate disturbance allows for the greatest diversity, because it allows both early and late successional species to exist
within an ecosystem.
Disturbance does not generally affect species richness.

Ecology and Biology: Shannon Diversity Index: Definition & Example
The Shannon Diversity Index (sometimes called the Shannon-Wiener Index) is a way to measure the diversity of species in a community.
Denoted as H, this index is calculated as:
H = -Σpi * ln(pi)
where:
Σ: A Greek symbol that means “sum”
ln: Natural log
pi: The proportion of the entire community made up of species i
The higher the value of H, the higher the diversity of species in a particular community. The lower the value of H, the lower the diversity. A value of H = 0 indicates a community that only has one species.
The Shannon Equitability Index is a way to measure the evenness of species in a community. The term “evenness” simply refers to how similar the abundances of different species are in the community.
Denoted as EH, this index is calculated as:
EH = H / ln(S)
where:
H: The Shannon Diversity Index
S: The total number of unique species
What is the Shannon diversity index value for this community?

By law, one of the habitats must be left intact to satisfy the zoning laws. The developer works with an environmental engineer to choose which of the habitats should be saved. The environmental engineer suggests that Site C should be saved. Which of the following choices best justifies this decision?Responses A) Site C has greater species richness and species evenness than either Site A or Site B. This will promote the maximum sustainability for future generations of animals. B) Site C is tied with Site A for greatest species richness, but unlike Site A, it has representative species from all 3 of the sites within it. C) Site C not only contains the greatest number of species, it also has the greatest genetic diversity within each species.

Over the next 5 years the area was monitored. The community's diversity, abundance, and richness all increased slightly during the first year however after the first year only the abundance went up during the following 4 years with no changes in any other area.
