Which of the following equations defines population size?   Question 3 options:    (Pt+1) = B - I + D + I – E   (Pt1) = N2 + I - D + B – E   (Pt2) = Pt1 + B - D + I – E   (Pt) = B - I + D – E   (Pt+1) = B - I + D + I – E

I want the results to be described in words.

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? A.) Growth rate (gr ) B.) Biotic potential (r) C.) Density (Dp ) D.) Per capita growth rate (cgr ) 2.) 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

You are evaluating multiple populations of the Karner Blue Butterfly. Below is the pairwise FST Values for the 3 populations you sampled. Given what you know about FsT and your results make a recommendation to the NYS Department of Environmental Conservation about how to manage the populations. Population 1 Population 2 Population 3 Population 1 Population 2 Population 3 0.05 0.67 0.46 (Hint: The measurement of gene flow (FSt) between population 1 and population 2 is 0.05) O a. The results suggest that each population is quite different from the other, such that each population should be managed as a distinct and unique population. O b. Populations 1 and 2 are completely isolated from each other and should be managed separately even though they are both more similar to population 3. O c. There is evidence of gene flow between populations 1 and 2, and they should be managed as a single population while population 3 is unique. O d. There is no evidence of differentiation between all…

(Number marked × total number recaptured)# recaptured with mark/Number marked × total number recaptured# recaptured with mark The formula above is the equation for estimated population size using the Mark and Recapture method of population estimation.  I initially catch and tag 10 rabbits.  Later I recapture 50 total rabbits and 10 of those are marked.  What is the estimated population size of this rabbit population?    Question 22 options:   500 rabbits   20 rabbits   2 rabbits   50 Rabbits

Salt is notoriously dangerous to land snails; however, some populations of aquatic, freshwater snail have brackish (or a mix of salt and fresh water) water adaptations and live in different parts of a river system. A group of scientists monitored salt concentrations in the habitats of two freshwater snail populations located nearby and recorded the data as follows (in ppt, parts per thousand): Population 1 (Day 1):  0.1 ppt (morning), 0.0 ppt (afternoon), 0.1 ppt (evening) Population 2 (Day 1):  0.3 ppt (morning), 0.5 ppt (afternoon), 0.2 ppt (evening) In 3–5 sentences, 1) describe how these results show why the brackish water adaptation may be necessary, and 2) explain how to determine whether the inherited adaptation is influenced by environmental factors.

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.

How do you calculate N (population size)? Is the mark-recapture method a reliable way to estimate population size?
