Chapter 43, Problem 1TY

A student decides to conduct a mark-recapture experiment to estimate the population size of n x l x m x l x m x mosquitofish, a species of freshwater fish, in a small pond near his home. In the first catch, he marked 45 individuals. Two weeks later, he captured 62 individuals, of which 8 were marked. What is the estimated size of the population based on these data?

Summary Introduction

Introduction:

In biology, population size is the definite number of organisms in the population. The total population size is calculated by given formula:

Number of individuals in 1stcatchTotal population size, N=Number of marked recaptures in 2nd catchTotal number of 2nd catch

OR

Total population size, N=Number of marked individuals in 1stcatch×Total number of 2ndcatchNumber of marked recaptures in 2ndcatch

Populations are made of all individuals belonging to the same species who live together at the same time.

The density of population is the count of organisms per geographic area or volume, per unit. For example, the number of organisms per square meter, per hectare or per square ilo

Answer to Problem 1TY

The correct answer is option (b) 349.

Explanation of Solution

Explanation/justification for the correct answer:

Option (b) 349.

If,

Marked mosquito fish in 1st catch = 45 individuals

Recaptured mosquito fish in 2nd catch = 62

Marked recaptured mosquito fish in 2nd catch= 20, then according to the formula,

Totalpopulationsize, N=Numberofmarked individuals in1 stcatch× Total number of 2 ndcatchNumberofmarked recaptures in 2 ndcatch=45×628=27908=348.75349

From the equation, the estimate total population size of mosquito fish is 348.75349

So, this is the correct option.

Explanation for incorrect answer:

Option (a) 134. As explained in option (b), the estimated size of a population is not matched to given data. So, this is an incorrect option.

Option (c) 558. As explained in option (b), the estimated size of a population is not matched to given data. So, this is an incorrect option.

Option (d) 1.016. As explained in option (b), the estimated size of a population is not matched to given data. So, this is an incorrect option.

Option (e) 22.320. As explained in option (b), the estimated size of a population is not matched to given data. So, this is an incorrect option.

S2) Below are two tables showing the population size and deaths by age for one year in the states of Louisiana (LA) and Florida (FL). Use the data to answer the following questions. You may use the blank cells in the tables for calculations and to show answers Age group 0-15 16-70 71+ Louisiana Deaths 30 215 585 Florida Age group Deaths 0-15 16-70 71+ 25 400 725 Population 165,000 300,000 75,000 Population 90,000 435,000 225,000 a. Calculate the overall crude mortality rates for LA and FL expressed as per 100,000 population. LA: FL: b. Calculate the age-adjusted mortality rates using the combined population as the standard. c. Explain what accounts for this difference in crude rates and adjusted rates between LA and FL.

You are contracted by the City of Ottawa to estimate the size of the population of small mouth bass in Dow's Lake. Using nets, you capture, mark, and release 48 bass. You return to Dow's Lake two weeks later and use the same techniques to sample more bass. This time, you capture 39 bass, 18 of which you had previously captured (marked ones). What is the estimated size of the population of small mouth bass in Dow's Lake? Round your answer to the closest whole value. You can round up or down if your answer is exactly between two values (i.e. 0.5).
