Two species of bird live in the same tree. Seeds only grow at the tops of the tree and insects only live at the bottom of the tree. Bird species A lives in the tops of the trees and eats both insects and seeds. Bird species B lives in the bottom of the tree and only eats insects. Which of the following describes why these two species live together in the same community? Group of answer choices Species A and Species B have the same fundamental niche. Species A and Species B have the same realized niche. Species A and Species B have a different fundamental niche. Species A and Species B have a different realized niche.

Which community would be expected to have the highest species richness? Group of answer choices A community that inhabits a small geographic area near the poles. A community that inhabits a small geographic area near the equator. A community that inhabits a large geographic area area near the poles. A community that inhabits a large geographic area near the equator.
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.
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
If an overlap develops between the ranges of two closely related species, and if the species occupy the same niche in the zone of overlap, what will probably happen in the zone of overlap? Group of answer choices: One species will take over most or all of the zone of overlap. The species will partition the zone so that half of it is added to the range of each species and there is no overlap. Both species will coexist, provided the environment in the zone of overlap is different from that in either individual range. A new species will arise by hybridization. Both species will coexist, provided the environment in the zone of overlap is similar to that of one of the individual ranges.
Which of the following is true about a community's species diversity? If a community has species richness, it automatically means it also has species diversity. A community can only have either species richness or species diversity, but not both A community can have either species richness or species diversity, or both. None of the above
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…
Another ecologist reported a diversity index value of 1.511 in a different community nearby the one you studied. This community is _ diverse than the one you calculated. Please see the attached image to get a better grasp of the question. How to Calculate Biodiversity and Ecology College Biology 2 Advanced Concepts Background Information In the Shannon index, p is the proportion (n/N) of individuals of one particular species found (n) divided by the total number of individuals found (N), ln is the natural log, Σ is the sum of the calculations, and s is the number of species... Species Evenness Species evenness takes into account the number of species and the relative abundance of species in a community. Several indices have been proposed. Two of the commonly used measures of evenness are the Shannon index (H) and the Simpson index (D). Question 2: What is the Shannon diversity index value for this community? What is the species evenness for this community?
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
In this class, we have discussed how populations form communities to create ecosystems and learn that comparing different communities could be done simply by determining species richness or species diversity. But to fully explore an ecosystem, we have to discuss the major components of its biodiversity. What are the major components of biodiversity and what is the importance of biodiversity?
A recent United Nations analysis report gathered data on declines in biodiversity across the world. Using the graphs provided, which statement shows an area of concern and is an alternative to the general hypothesis "Humans are responsible for a significant increase in the extinction rate among species in the world today as a result of damage caused to the environment"? A. Fertilizer use in developing countries should be encouraged to decrease the extinction rate B. Decreasing air pollution in the least developed countries would decrease species survival rate C. Protection of key biodiversity areas should be a priority for developed countries to lower the extinction rate D. Assisting developing countries with more sustainable methods of extraction of living biomass would increase species survival rates
A niche is loosely defined as an organism's role in its environment, which can include factors like, feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Considering Gause's law, conduct research on the California Red Legged Frog and the Northern Pacific TreeFrog (use wiki or other google search). Create a chart that compares the two with regard to their niche or their lifestyle that may explain how these two native frogs have evolved to coexist in the same ecosystem.
