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…

Biodiversity is the study of the variety of life. Which of the following is/are ways we can measure biodiversity? Endemic Species Ecosystem Genetic Climate Community Species

Match the problems for biodiversity with the solutions.     Train more scientists.   Establish payments for land managed to enhance conservation.   Train and hire local people to work in protected areas.   Understand the diverse values of different societies and organizations.   Financial subsidies to industries that damage the environment should end.   1. Ecosystems lack monitoring. 2. Economic decision making often fails to include ecosystem services. 3. Revenues associated with protected areas do not directly benefit local people. 4. Endangered species occur on private land. 5. Many businesses remain uninterested in conservation issues.

Biodiversity is described as: The seasonal and daily changes in an environment The range of different species in an environment The influence of physical factors on an environment The way species differ from one another

The biodiversity of the planet is rapidly being depleted. Scientists' efforts to monitor and protect biodiversity are being aided by a slew of new technologies and the volunteer work of ordinary citizens. To help scientists in their conservation work, new technologies have been developed. For example, Footprint identification technique (FIT) uses photo digitization to identify the footprints of large cats and other mammals, which will allow collection of data about these animals in a noninvasive manner. Other noninvasive data collection techniques include vocalization identification, drones, DNA analysis, and camera-trapping. Apps such as eBird and iNaturalist allow amateurs to record their observations in open-access online databases for further analysis. Smartphones and drones could be useful in collecting data to prevent poaching, although such technologies are in their infancy and still not widely available in developing countries. Remote sensing could be used to monitor changes in…

PoN Background Information: In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus, the forest management personnel feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service decided to bring in natural predators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and als increase the deer quality (or health), as predators often eliminate the weaker members of the herd. In 1971, ten wolves were flown into the island. The results of this program are shown in the following graph (below). Deer and Wolf Population Size 2500 2400 30 -28 2300 -26 24 2200 +22 whlf -20 2100 18 -16 2000 14 deer -12 1900 -10 1971 1972 1973 1974 1975 1976 1977 1978 1979 1980 Describe what happened to the deer and wolf…

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?

Biodiversity occurs where a large variety of different plants and animals live in an area. The more varied the populations within the community, the greater the change for these organisms to survive. Biodiversity often measures the health of a community, biome, or ecosystem. When diverse populations are no longer sustained by an ecosystem, extinction of a species can occur. 17 Which of the following is most likely to have a positive effect on biodiversity? A Increasing people's awareness of pollution B Replanting trees and other plants in a park C Recycling glass, aluminum cans, and plastic D Pouring oil onto the ground

On a separate sheet of paper. A. Classify the Value of Biodiversity: Give thevalue of each organism below (you can write more than one value for each organism) andclassify it by putting a check (/) on the space under the correct column.

nd biodiversity of sites in their own community, students performed a leaf litter lab where leaf litterwas collected from two sites: one from beneath the trees in an organically managed, commercial landscapeestablished one year ago and one from beneath the trees in a nearby nature preserve that have not been trimmed ormanaged in over twenty years. The students hypothesized that there would be more insect biodiversity in the leaflitter at the nature preserve than at the managed site. The leaf litter from each site was placed into a funnel with alight shone on the top to drive any insects out of the litter. Species were collected in an alcohol-filled containerbelow the funnel, and the species were identified using magnifying lenses and a key

Please create an interactive dichotomous key, which children will be able to use to explore their environment. (any type of environment)   Also in the interactive dichotomous key please fully explain what biodiversity is.  also, explain the importance of biodiversity to the current environment and the cultural importance.

The implications of preserving biodiversity go beyond ecology. Social and cultural benefits are significant, especially in the less developed nations. In the United States, we are fortunate to have notable examples of socio-cultural connections to biodiversity. In this exercise, I simply want you to become familiar with these two programs identified below. They are important because they involve places that can have meaningful connections to you - and other humans. We will get into the ecological details in later assignments. First, here are UNESCO's Biosphere Reserve and World Heritage programs. https://en.unesco.org/node/314143   Using the information in the link above, answer the following questions: Refer to this page on their website: https://en.unesco.org/biosphere/eu-na  https://whc.unesco.org/en/about/ 7. What is the nearest World Heritage site to you? https://whc.unesco.org/en/list/ 8. In concert with UNESCO, the Convention on Biological Diversity https://www.cbd.int/nbsap/ is…

Note:  Since you have posted a question with multiple sub-parts, we will solve the first three sub-parts for you. To get the remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.  Carrying capacity:  The resources present in the ecosystem are utilised by all the organisms that grow and thrive in the ecosystem. Since the resources present are limited the environment can support only a limited number of organisms. The maximum number of organisms that the environment can support is called the carrying capacity. Above the carrying capacity, there is completion for the limited resources.  Step 2 1. When we see the data representing the deer population from 1905-1939 we see that there has been a rapid increase in the deer population initially and then the population falls down drastically.  In the year 1915  The carrying capacity for the  Kaibab deer population was 30.000 deers for 30,000 hectares of land. If the see the deer…

A(n) community is a group of species that occupy the same area. When studying the diversity of a group of species, ecologists use two measures: One is a count of the total number of species in the area, which is called The other is a measure of how common the species are, compared to each other, which is called
