QUESTION 2: Population size One weekend in early July, a total of 154 Marbled White butterflies were captured and marked before being released. The following weekend, the butterfly traps captured another 87 butterflies, but only one was marked. a) Based on these data, estimate the butterfly population size (show your workings in full). b) Estimate the population size if, instead of one, the number of marked butterflies was: i) 2 ii) 10 iii) 25 You do not need to show your workings for this part. c) Would all of these results give equally accurate estimates of population size? Explain your reasoning. d) The following year, the researcher returned to the same spot, on the same July weekend in order to evaluate whether the butterfly population size was similar year-on-year. This time, however, the recapture phase occurred only three days after marking. Do you think this would affect the accuracy? Explain your answer fully.

QUESTION 4 a. i. The capture and release method (Lincoln index) is used to estimate the size of a population. List TWO assumptions that are made, when utilizing this method. ii. To estimate the population size of rats mark and recapture exercise was conducted. 150 of the animals were randomly captured and tagged in the first sampling effort. After four weeks a second sampling effort was carried out during which 110 rats were caught, 50 of these possessed tags given in the first sampling. Use the Lincoln index equation to estimate the population size of rats in Bridgetown Bridgetown, a iii. Suggest one scenario that could occur within the 1-month period between sample taking, which could lead to a LOWER population estimate.
Question: The Jack Rabbit population of the Bowl grows from 49 to 1004 individuals over 10 years. a) Grounds Keepers decide to examine the Jack Rabbit population around the Education building. Initial surveys find 23 individuals. They hire you to predict the size of the Education population in 5 years based on the observations in the Bowl. The following formulas are available for use:

Need help with 1 and 2 questions: 1.) Two different populations of commander butterfly were studied over a period of two years. The following results were obtained. Population size of commander butterflies Population| Original size| Final size 1 2436 2873 2 2185. 2649 Which of the following concepts would best compare the change in population size of the two populations?

When population density reaches the carrying capacity of the environment, the death rate in the population becomes A.) less than the birth rate B.) equal to the birth rate C.) more than the emigration rate D.) more than the immigration rate
PLEASE HELP! Question: Brown marmorated stink bugs are native to China and Japan. They were identified in Pennsylvania for the first time in 1998 and have since spread across North America, feeding on agricultural crops. Which of the following characteristics of the brown marmorated stink bug has led to them being an invasive species in North America? A. They reach maturity slowly. B. They are tolerant of a wide range of environmental conditions. C. They are often eaten by native wasps and birds. D. They have only a few surviving offspring each year.
Question 3: I introduced 2 species of super-mutant ant species into my terrarium. These are the only species competing for resources. Species 1's common name is the TEN-headed ZINGer ant and they have a population size of N1 and a carrying capacity of K1. The blue line shows the isocline for species 1. Species 2's common name is the Evil Ant. The population size of species 2 is N2 and the carrying capacity is K2. The green line shows the isocline for species 2 The red dot is the present combination of N1 and N2. Part a) Given the data how will the population of both species (N1 and N2) change- pick the correct colored arrow (pink, brown, black, or red) to show the direction that the combination of N1 and N2 will change
QUESTION 4 A population of seed-eating birds of species A has 100 individuals, intrinsic growth rate (r) =0.2 and carrying capacity = 1000. 50 individuals of another species (B) of seed-eating birds are introduced into the same environment. If the birds of species B are two times smaller and eat two times less food than the birds of species A, how the growth rate of the population of species A will change after this introduction? O It will increase 4 times O It will not change O It will increase 2 times O It will decrease QUESTION 5 What types of species interactions are used for biological pest control?

QUESTION:- Community A receives its water from several sources. The water source responsible for causing an outbreak of disease X is unknown. The best evidence to determine which suspected water supply is responsible would be: Question 19 options: a. the identity of the water supply providing water to the largest proportion of cases. b. the relationship between quantity of water consumed and the severity of attack for each individual. c. the identity of the water supply that has the greatest opportunity for contamination during the epidemic. d. the attack rates for disease X in those who did and did not drink from each water supply.
Question 1. Is the population in H-W equilibrium? Observed genotype frequencies ● ■ ● f[A₁A₁] =0.16 f[A₁A₂] =0.48 f[A₂A₂] =0.36 O Question 2. Is the population in H-W equilibrium? Observed genotype frequencies f[A₁A₁] =0.04 f[A₁A₂] =0.12 ● f[A₂A₂] =0.84 ● Question 3. Is the population in H-W equilibrium? Observed genotype numbers A₁A₁ =40 A1A2 =20 ● A₂A2 =40 O Question 4: Is the population in H-W equilibrium? Observed number of each genotype A1A1=36 ● ● A1A2=28 A2A2=36 Note that raw numbers are given. The question is whether observed frequencies = expected frequencies. You must first compute the genotype frequencies.
