Dependent variable description<\/p>\n
Be as complete in your description as possible Potential values<\/p>\n
List the potential values for the variable Categorical or quantitative?<\/p>\n
Number of eggs laid by adult female sedentary bean beetle 0 to infinity quantitative<\/p>\n
Number of successful copulations<\/p>\n
0 to infinity quantitative<\/p>\n
What are your study subjects? Be as precise as possible.<\/p>\n
Adult sedentary female bean beetles<\/p>\n
What is your hypothesis? If you have multiple independent or dependent variables, provide separate hypotheses for each.<\/p>\n
Morph of adult male bean beetles affects number of eggs laid by adult female sedentary bean beetle<\/p>\n
Morph of adult male bean beetles affects the number of successful copulations with adult female sedentary bean beetle<\/p>\n
What is your prediction? If you have multiple independent or dependent variables, provide separate predictions for each.<\/p>\n
If morph of adult male bean beetles affects the number of eggs laid by adult female bean beetles, then adult sedentary female bean beetles who mate with adult sedentary male bean beetles will produce more eggs than adult sedentary female bean beetles who mate with adult dispersal male bean beetles.<\/p>\n
If morph of adult male bean beetles affects the number of successful copulations with adult female sedentary bean beetles, then adult female sedentary bean beetles that copulate with adult male sedentary female bean beetles will have more successful copulations than adult female sedentary bean beetles who copulate with adult male dispersal bean beetles. <\/p>\n
Explain the rationale for each prediction. Why do you think this is a reasonable prediction for what will happen? Include at least one citation for each prediction.<\/p>\n
Sedentary female bean beetles are known for producing more eggs than dispersal female bean beetles so if sedentary female bean beetles\u2019 mate with male sedentary bean beetles who have similar environmental conditions during development from larvae to the pupa stage, then the sedentary male bean beetles will more likely have more nutrients to provide to the sedentary female bean beetle as opposed to dispersal male bean beetles who share traits with female dispersal bean beetles. The identity of the mate may thus affect female reproductive performance(Arnqvist, Nilsson, Katvala<\/p>\n
Sedentary female bean beetles are known to be selective when choosing a mate and will prefer the adult male bean beetle who can provide the most nutrients for the offspring, who we predict will be the sedentary male bean beetle. The effects of multiple mating on female fitness are clearly multifaceted in\u00a0C. maculatus\u00a0(see Introduction).\u00a0Eady et al. (2000)\u00a0showed that females copulating with multiple males lay more eggs, but have offspring with a lower egg-adult survival, than do those copulating repeatedly with the same male, at least under some conditions.(Arnqvist, Nilsson, Katvala)<\/p>\n

Why would a biologist who doesn\u2019t study bean beetles find this topic interesting? Answer this question by connecting your proposal to a \u201cbig picture\u201d in biology.<\/p>\n
We could see if the population of bean beetles could be increased by mating either adult male dispersal morphs or adult male sedentary morphs with adult female sedentary morphs. We might not be interested in increasing their population in the natural environment, but it may be of use to some question dealing with populations of certain insects such as bees which are considered important to the environment<\/p>\n
PART 2: Detailed study design, procedure, and annotated bibliography<\/p>\n
DETAILED STUDY DESIGN & PROCEDURE<\/p>\n
Is your study an observational study or an experiment? Please explain.<\/p>\n
Experimental because the independent variable is being manipulated.<\/p>\n
If your study is observational, you may skip to question 11.<\/p>\n
What are the treatments in your experiment? List all the treatments and identify them as control or experimental.<\/p>\n
Observational<\/p>\n
How will you establish your treatments? In other words, what are you going to do to set-up your treatments? For example, if your treatments are 20\u00b0C and 30\u00b0C, describe how you\u2019ll expose your study subjects to those temperatures.<\/p>\n
How are you going to measure the dependent variable(s)? Be as specific as possible. For example, if you are measuring growth rate, I want to know how you will measure growth and how you will calculate growth rate from those data.<\/p>\n
We will count the number of eggs seen on the bean through the lens of a microscope.<\/p>\n
We will also count the number of successful copulations by adult bean beetles through a microscope.<\/p>\n
List at least 10 potentially confounding variables that could impact your measurements of the dependent variable(s).<\/p>\n
Variable descriptions<\/p>\n
Be as complete in your description as possible Potential values<\/p>\n
List the potential values for the variable Categorical or quantitative?<\/p>\n
1 Temperature of lab (Celsius) 0 to infinity quantitative<\/p>\n
2 Mating history of adult male bean beetle Mated or unmated categorical<\/p>\n
3 Mating history of adult female bean beetle Whether or not Mated categorical<\/p>\n
4 Condition of bean used for oviposition Used, fresh categorical<\/p>\n
5 Temperature of environment raised in 0 to infinity quantitative<\/p>\n
6 Oil treatment used on bean Neem oil, sesame oil, untreated categorical<\/p>\n
7 Age of adult male bean beetle(days) 0 to infinity quantitative<\/p>\n
8 Age of adult female bean beetle(days) 0 to infinity quantitative<\/p>\n
9 Type of bean used for oviposition Adzuki, black eyed peas, etc. categorical<\/p>\n
10 Sucrose given to adult male bean beetle Sucrose or no sucrose categorical<\/p>\n
What is an appropriate sample size?<\/p>\n
(n = 20 adult female sedentary bean beetles per group)<\/p>\n
Write a detailed procedure for your study. This should be a complete list of steps describing how you would perform your study and control potentially confounding variables.<\/p>\n
Use 5.5 cm petri dishes to store bean beetles separating by sex and morph <\/p>\n
Place adult female bean beetle in petri dish using tweezers on microscope stage<\/p>\n
Place adult male dispersal or sedentary morph using tweezers in with female<\/p>\n
If copulation successful after a few minutes when male bean beetle inserts aedeagus into female bean beetle remove both adult bean beetles using tweezers<\/p>\n
If copulation not successful after more than 3 attempts replace adult male bean beetle using tweezers<\/p>\n
If copulation still not successful replace adult female bean beetle using tweezers<\/p>\n
Repeat steps 1-6<\/p>\n
Place 20 black eyed beans in petri dish for female bean beetle to lay eggs on<\/p>\n
Create a single slide using Microsoft PowerPoint as a visualization of the design for your study. The slide must accurately and completely represent the main components of your study (e.g., treatments, timing, measurements) with clear, appropriate graphics and minimal text.<\/p>\n
Upload the PowerPoint slide (.ppt or .pptx) with your proposal worksheet.<\/p>\n
Set-up an Excel Workbook that you could use to collect and organize your data. This means (1) label the columns you\u2019ll need and (2) include a completed metadata sheet that provides more details about what data you would report in each column. A template file with the metadata tab has been provided on D2L.<\/p>\n
Upload the Excel Workbook (.xls or .xlsx) with your proposal worksheet.<\/p>\n
In your Excel Workbook, make a properly formatted graph (with all the components we have practiced!) illustrating what your results would look like if they supported your prediction. The graph must be consistent with your prediction and sample size. You will make up numbers to represent the data, so be sure to include variation so the standard deviation can be calculated.<\/p>\n
Upload the Excel Workbook (.xls or .xlsx) with your proposal worksheet. This can be the same file as what you submit for question 15.<\/p>\n
What statistical analysis would you perform on your results? Explain why this is appropriate, and be sure to include every test you would run and every reason you would choose it! DO NOT ANALYZE YOUR MADE-UP DATA!<\/p>\n
Since we have two quantitative dependent variables and a categorical independent variable, and we are comparing the averages between two groups we will perform a T-test and possibly a Wilcox test.<\/p>\n","protected":false},"excerpt":{"rendered":"
