Explain when you should use a species-area curve and when you should use a sampling effort curve.
In this case, it is important to know, what kind of data is used in these two types of curves. In the case of Species-Area Curve, we put in the y-axis the cumulative number of species and in the x-axis, we put the cumulative area. This will show us a relationship between the area and number of species. This kind of graph is mainly used to know the variability and amount of a single type of organism or species in the same tropic level.
In the case of sampling effort curve, in the X axis we will put the cumulative numbers of species and in the y-axis the cumulative number of individuals. This type of graph help us to determine the total number of species represented by the individuals that we used as sample.
In the species-Area Curve, we want to know how many species are in a determined are while in the sampling effort curve we want to know the relationship between the species observed and the number of the sample.

during a biodiversity sampling exercise an undergraduate found 52 species of bees in one area of canpus yet calculated that there were pribably 72 species if bees in that specific area of the campus. why is there typically a discrepancy between the number if different specues caught and the calculated value quizlet
For a one-tailed test, the p-value is: a) twice the area under the sampling distribution curve between the mean and the observed value of the sample statistic b) the area under the sampling distribution curve to the same side of the value of the sample statistic as is specified in the alternative hypothesis
Explain in what circumstances you should use the Sharpe Ratio and when you should use the Treynor Ratio to compare mutual funds.
To what extent should auditors use sampling? What problems do auditors face when using sampling methods?
Explain and provide two examples each of probability sampling and nonprobability sampling. When is probability sampling a better sampling strategy? When is nonprobability sampling?
Use of discretionary policy to stabilize the economy Should policymakers use monetary policy, fiscal policy, or both in an effort to stabilize the economy? The following questions address the issue of how monetary and fiscal policies affect the economy and the pros and cons of using these tools to lessen economic fluctuations. The following graph shows a hypothetical aggregate demand curve (AD), short-run aggregate supply curve (AS), and long-run aggregate supply curve (LRAS) For the economy in May 2020. According to the...
4. Sampling methods for population ecology (a) Please explain the following sampling methods: Census Area-or volume-based surveys Mark-recapture method Line-transect survey Which method can produce the most accurate population data? This note is prepared by
Can someone please explain this one to me? Which of these plant species is most likely to become an invasive pest with uncontrolled growth when introduced into a new area? A] It becomes mature quickly and reproduces at an early age B] it is closely related to another species already living in the area C] it has a long life span and a ‘late loss’ survivorship curve D] it relies on certain species of animal for pollination and seed dispersal...
can you explain the workings (1 point) Find the area under the curve y = 1/(7x) from 1 to 2 = t and evaluate it for t = 10,4 = 100. Then find the total area under this curve for 2 > 1. (a)t = 10 (b) t = 100 (c) Total area
7. Use of discretionary policy to stabilize the economy Should the government use monetary and fiscal policy in an effort to stabilize the economy? The following questions address the issue of how monetary and fiscal policies affect the economy, and the pros and cons of using these tools to combat economic fluctuations. The following graph shows a hypothetical aggregate demand curve (AD), short-run aggregate supply curve (AS), and long-run aggregate supply curve (LRAS) for the U.S. economy in April 2020. Suppose the government...
