Question
Chapter 60, Problem 3CQ
Summary Introduction
To describe: The way in which diversity,stability, redundancy, keystone, and idiosyncratic hypotheses link species richness with ecosystem function.
Introduction: The species richness of any particular area is called as the biodiversity of that area. The biodiversity includes various species of both fauna and flora in a particular habitat. The species richness has a direct relationship with the productivity of the ecosystem.

INTRODUCTION: Quadrat sampling is a classic tool for the study of ecology, especially biodiversity. In general, a series of squares (quadrats) of a set size are placed in a habitat of interest and the species within those quadrats are identified and recorded.
QUESTION: What are the advantages and disadvantages of a quadrat sampling method?

- Describe resource partitioning. Refer to partitioning in space and time. Refer to partitioning withing a species.arrow_forwardConsider this claim: Changes in environmental conditions always result in new ecosystems and loss of biodiversity characterized by an increase in the number of some species, the evolution of new species, and the extinction of some species. Use what you have learned from the lesson, as well as reliable and reputable resources, to evaluate this claim. Use at least three examples from the lesson and other sources to support the valid ideas in the claim and refute the invalid ones. Add a list of your resources at the end of your response. Then, draw a conclusion about the stability of ecosystems, how and what can affect the stability of ecosystems, and how changes in the environment may affect the types and number of living things in an ecosystem.arrow_forwardA niche is loosely defined as an organism's role in its environment, which can include factors such as feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Keeping Gause's law in mind, do some research on the California red-legged frog and the North Pacific tree frog (use wiki or another Google search). Create a chart comparing the two with respect to their niche or lifestyle that can explain how these two frogs can co-exist in the same ecosystem.arrow_forward

Cite specific example(s).arrow_forwardConsider an ecological network consisting of three interconnected habitats (A BCA). Ecologists want to model the occupancy dynamics of a particular species "Species" across these habitats over time using a discrete time discrete state stochastic process. State Space: State 0: Species X is absent from all habitats. State 1: Species X is present in Habitat A State 2 : Species X is present in Habitat B. State 3: Species X is present in Habitat C. State 4: Species X is present in Habitats A&B State 5: Species X is present in Habitats A&C. State 6: Species X is present in Habitats B&C. State 7: Species X is present in All Habitats. Transition Probabilities: Rule 1: The probability of colonizing an adjacent habitat is 0.2. Rule 2: The probability of extinction from a habitat is 0.15. Rule 3: The probability of recolonization of a random habitat is 0.1 A) Draw a schematic diagram of the Markov Process illustrating states and transitions.

- When each species in a community has the same number of individuals (i.e., relative abundance), the effective number of species is equal to Select true or false for each option. 1/D [ Choose ] [ Choose ] Number of species in a community (S) [ Choose ] Species Richness [ Choose ] Phylogenetic Diversity [ Choose ] > > >arrow_forwardDetermine if each statement is correct or incorrect: 1. Ecosystems with fewer numbers of species tend to be less stable. 2. Increasing numbers of species lead to more redundancy which is bad for the ecosystem. 3. More species mean more niche separation. 4. Species with a low resistance will also have low resilience. 5. Disturbances to ecosystems can be both naturally occurring and human caused. 6. Stresses to ecosystems are useful for removing weaker species and ensuring the strongest survive. 7. Bringing non-native species into an area to increase biodiversity makes the ecosystem more stable.arrow_forwardCarefully distinguish between deterministic and stochastic models of succession. Use illustrations. Using an example, give an example of how these would differ in predictions of future ecological communities. Which one is supported by most empirical evidence today?arrow_forward
- EXTENSION: Biodiversity has many components. "Relative abundance" is a measure of how abundant the members are for one specific population when compared to all the living things in a community. The formula for this is: Relative Abundance (%) = [(# organisms in population of interest) / (total number of organisms in the community)] x 100 Given a 100 m² plot where the following species of grasses are present, calculate the relative abundance for species 4. Write your answer in the space below. Give your answer as a percentage. Round to the nearest whole number.
