A large lake contains an abundance of rainbow trout. You capture 75 trout, tag and then release them. You then capture another sample of 200 trout. Of the 200 trout in this second sample, 15 have tags. a) Estimate the number of trout in the lake using the mark-recapture technique. b) What assumptions do you make when using the mark-recapture technique? state 2 assumptions and explain why they are important.

A population with three life-stages separated by 3 years is modelled by a Leslie matrix, resulting in these predictions. The x-axis shows the number of time steps in the vector dynamics from the Leslie matrix multiplication. How many years before the long-term dynamics take over? a) 0 b) 2 c) 5 d) 15 What is the long term prediction for this population? a) decreases to zero b) anything could happen c) increases to infinity d) stable If the population started with many more animals and in different proportions from each life stage, would the prediction be the same or different? If the population started with many more animals and in different proportions from each life stage, in the long term dynamics what would be the ratio of newborns (stage 1) to youths (stage 2) to adults (stage 3). a) about 1 to 1 to 1 b) about 4 to 2 to 1 c) about 6 to 3 to 1 d) no way to judge
In a study on the ecological impact of malarial infection in the lizard Scelopons occidentalis, researchers caught 15 lizards with the malarial parasite Plasmodium and 15 without. Researchers measured the distance (meters) each lizard could run in two minutes (as a measure of stamina). The following is the code and R output from the "t.test" function. t.test (x=infected, y=uninfected) Welch Two Sample t-test data: infected and uninfected t = -1.9658, df = 27.239, p-value = 0.05959 alternative hypothesis: true difference in means is not equal to 0 95 percent confidence interval: -10.9523489 0.2323489 sample estimates: mean of x mean of y 26.87333 32.23333 The confidence interval includes the value of 0, therefore we conclude that: a. The difference between the treatment and the placebo is positive b. There is no difference between the treatment and the placebo OC. The difference between the treatment and the placebo is negative Od. There is a difference between the treatment and the…
The pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally. When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes? a) The proportion of DDT-resistant mosquitoes in a population remains constant due to the metabolic costs of DDT utilization b) Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. c) DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. d) Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT.
For your summer research project, you decide to repeat Lillian Tuttle’s (2017) experiment testing the effect of lionfish on other fish that are cleaners and clients. You do this new experiment at a new location (Bonaire), but use basically the same experimental approach and BACI design as Tuttle. a) You do not separate resident and transient clients (as Tuttle did), and below is a graph of your results showing the effect of the treatment on the total density of client fish in the community. Please explain your result. Imagine that you are planning to publish your experiment and that your answer to this question will be part of the “Results” section of your paper. Please do not worry about hypothetical statistical tests; just assume that the obvious patterns displayed in the graph can be interpreted at face value.
You wish to determine the abundance of the state- and federally-endangered Prairie Fringed Orchid (Platanthera lecuophaea) in a local prairie. (a) The prairie is approximately 100 acres of relatively flat terrain. Considering the “basic” sampling strategies, what might be a good sampling design (can just give the name)? Why? (b) You decide also to evaluate the abundance of the orchid in another prairie. The second prairie is of similar size but has a hilly terrain. What might be a good sampling strategy? Why?
Which of the following is the best definition of the term controlled variables? a) The variable is what is measured or recorded in the experiment. This is the variable in an experiment that the researcher can change and b) control A treatment level that is often used for comparison, it is usually zero or a c) natural level. d) The things in an experiment that are kept the SAME for every level of treatment. e) A statement explaining an observation.
What is the null hypothesis? Group of answer choices a)The hypothesis that any patterns in the observed data is due to chance alone and therefore significant. b)The hypothesis that the observed data is invalid c)The hypothesis that any patterns in the observed data is due to chance alone and therefore not significant. A scientist usually accepts a p-value (or alpha level) of 0.05 as the threshold value to reject the null hypothesis. Group of answer choices a)True b)False

When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes?* nd 2 chool The proportion of DDT-resistant mosquitoes in a population remains constant due to O the metabolic costs of DDT utilization DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1.492 finches is intróduced to a rainforest. Over the next year, the finches show a death rate of…
