Which one of the following statements is FALSE? Beta diversity is low when two ecosystems share the similar species and respective abundance. An intelligent meander records date, time, location and a list of species. Beta diversity or differentiation diversity compares alpha diversity among several communities. Species richness is the total species abundance in an ecosystem. Inventory diversity can be defined by alpha diversity, which is the number of species in a local forest stand.

These aspects of Joshua Tree National Park constitute what level of ecological organization? Group of answer choices Population. Species Interactions. Individual. Biosphere. Community.

Which one of the following is the number of individuals per unit area? A. distribution B. growth rate C. density D. geographic range
What is the difference between population density and population size? Population density is the number of different species live in an aggregation. The population size is the number of individuals within the species that have left the ecosystem. Population density is a measurement of how many species are living in a given area. The population size is the number of individuals within the species that make up the population. Population density measures the space a species occupies in a given area, but the number of individuals in the space is not included in this measurement. Population size is the number of varying species that live in a given area. Population density is the number of individuals of a species that make up the population. Population size is the number of individuals of a species that are living in a given area.

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…

Which of the following statements about the concept of ecological niche is correct? A species' realized niche, may or may not be the same as its fundamental niche The fundamental niche of a species includes biotic and abiotic factors while the realized niche only includes biotic factors A species' fundamental niche is always smaller than its realized niche A niche is the same as a habitat
You have been researching the biodiversity of different species of lizards in the Florida Everglades. You select a one square acre plot of land and begin tagging and counting the different reptiles found in that area over 6 months. After 6 months of research, you collected the following data: Species Count Green Anole 16 Brown Anole 72 American Alligator 3 Burmese python 2 Corn Snake 9 Eastern Glass Lizard 8 Use the blanks below to answer the following questions: 1. What is the biodiversity index of the one acre lot observed? 2. If you collected the same information for a second square acre 10 miles away and determined that acre to have a biodiversity index of 0.37, would you consider the first area to be biologically diverse and why or why not? 3. What do you think is suppressing biodiversity in the first acre counted? a b c
