To determine: An endangered species or threatened species are more likely to become extinct.

Exotic or non-indigenous species are species that have been transported to new locations by humans, either intentionally (e.g., the ornamental trade, fisheries or aquaculture) or unintentionally (e.g., accidental release of aquarium or pet species), and have established one or more populations in their new location. Exotic species may become invasive species if they expand their range in their novel region and become abundant. The presence of invasive species is of concern because invasive species can have negative effects on the affected ecosystems or commercial interest.   Research an invasive species and include the following: Scientific name and common name (if the species has one) The species native region and invaded region Consequences or concerns that the species presents. Potential solutions Include references

If you wanted to work out why numbers of a Hawaiian species were declining, the first thing to check would be whether an invasive species was affecting it as this is the most likely reason. True False

Question: Think and research the effects of humans' buildings structures, communities, etc. on undeveloped land. Particularly, look at natural species in Texas, as well as the physical environment.

List two ways exotic species are introduced to a new habitat and list two consequences of it becoming an invasive species that takes over a habitat.

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? What…

Species richness quantifies the amount of money each species is valued at on the biodiversity stock exchange the relative abundance of species in a community. the number of species in a community the combination of the number of species in a community and their relative abundances

In a 50 square mile section of forest, there are some cut patches of forest where the trees have been removed and some patches of forest that have been left uncut. Birds are nesting in both cut and uncut forest patches. Beginning with the first step, place the steps in sequence for an investigation of the nesting birds using the scientific method. First step of investigation End of investigation Answer Bank Determine whether more birds nest in cut or uncut forest patches and share this conclusion with other researchers. Compare the data collected concerning nests from cut and uncut patches of forest. Observe birds nesting in cut patches and uncut patches of forest. Identify several patches of cut forest and several patches of uncut forest and decide how to conduct nest counts in them. Count the number of nests found and record the data. Hypothesize that more birds nest in cut forest patches.
