You travel to a continent that you’ve never traveled to before and you decide that you want to start studying community ecology on this continent. First determine whether the community that you are studying is considered an equilibrium (or stable) community. Describe what things you would study, why you would study them, and how understanding that would help inform whether the community was in equilibrium.

Expert Solution

The community is considered to be a stable community if the size of population of all species remain constant and should be in a state of climax community. According to Clements, a stable / climax community is defined as the final, terminal, stable community developed in the process of succession that maintains itself for over longer period in equilibrium with the prevailing environmental conditions. Resistance and Resilence are the components of stability for a community. The environmental factors should be in balance. It should have the following characteristics

S.No.	Form	Characteristics
1	Unity	All species are to be in the form of an organised unit. The life or growth forms of plants indicate its climate.
2	stability	The community to be stable with the climate. The climax community should not be replaced through competition. The community should have few characteristic dominant species.
3	Origin and phylogenetic relations	The stable community should be treated as organism in terms of birth, growth, development and maturity. The developmental stages of the cmmunity should have their own characteristics, reflecting the type of climate. As organism changing with age the climax communities should undergo changes and be stablely established.

The things to be studied are:

Climate - The stability of the community is studied by the regional climate. A stable climate will lead to stable community.
Temperature - Optimum temperature is needed for the plants to conduct photosynthesis and for metabolism of animals
Light - Light as a universal food source has to be abundant for the biotic components.
Availability of Oxygen and Carbondioxide - These abiotic factors in sufficient quantities help in the survival of species
Species richness - The species should exist independent of each other without much competition
Size of the population - The population size has to be constant maintaining balance between different species.
Resistance - The community should be resistant to invasions by alien species and natural and man made disturbances
Productivity - The productivity should show variation every year in a stable community

Variation 2. If you’ve never worked or you’re not personally familiar with an array of jobs, assume that you’re a manager of a small manufacturing plant. You need to hire people to fill two jobs. One job is for a plant custodian to sweep floors, clean bathrooms, empty trash cans, and so forth. The other job is for an office manager who will supervise a staff of three clerks and secretaries, administer the plant payroll, and coordinate the administrative operations...

Two vehicles travel along two distinct roads. The first vehicle traveled in the first roadway with a spot speed equal to “A veh/hr”, while the second vehicle traveled along the second roadway with a space mean speed equal to “A veh/hr”. If the two vehicles originated at the same position and will arrive at the same points, who will arrive at the destination first? Elucidate, and expound your idea based on the fundamental definitions and your logical reasoning.

A)In a study of distances traveled by buses before the first major engine failure, a sample of 191 buses results in a mean of 96,700 miles and a population standard deviation of 37,500 miles. Calculate the p-value corresponding to the test statistic used to test the claim that the mean distance traveled before a major engine failure is more than 90,000 miles and determine if the null hypothesis can be rejected at α = .01. b) A major car manufacturer...

On an isolated island you discover a vertebrate animal that has never been described before. It has feathers, a feathered, bird-like tail, lays hard-shelled eggs and can fly, but it has teeth instead of a beak. Provide an explanation for the evolution of this animal and possible relationship with other clades of vertebrates that accounts for this unusual combination of features.

4. You are given an animal whose development has never been characterized before. You note that at the four-cell stage, one blastomere transiently shows dark pigmentation. However, as embryogenesis proceeds, the dark pigmentation fades and you are unable to determine what becomes of the blastomere in the fully-developed embryo. a) [4pts] Describe a simple experiment you can do to determine the fate of the dark blastomere. Provide sufficient detail to show that you understand the technique and its interpretation. b)...
