Topic and analysis overview – Melichrus
You will conduct analyses (r studio) and write a report addressing the following topic.
Melichrus R.Br. is an Australian endemic genus of shrubs in the heather family, Ericaceae. There are currently six accepted species in the genus that have been described on the basis of morphological differences, four of which have broad distributions in eastern Australia. Morphological variability within those species (M. adpressus, M. urceolatus, M. erubescens and M. procumbens) suggest that there may be unrecognised species of Melichrus that will be revealed through integration of molecular and morphological methods. The two newest species, M. hirsutus and M. gibberagee, have very narrow distributions and appear to meet the criteria for conservation listing. If undiscovered species are also narrow endemics, they are unlikely to receive the protection they deserve unless they are recognised as distinct evolutionary lineages.
PhD student Helen Kennedy is revising the taxonomy of Melichrus using an integrative approach. They include a subset of her data focusing on populations that key out to four related species, with metadata describing their sampling locations and field determinations. With this data, you are to address the following questions:
1. Does molecular evidence support the current taxonomy? Which species are supported and which are not?
2. Are there distinctive genetic groups that may require description as new taxa?
3. Is there evidence of inbreeding, and does it represent a threat to any accepted or putative taxa?
4. Is there evidence of hybridisation, and does it represent a threat to any accepted or putative taxa?
You will need to examine the data, and/or appropriate subsets, using population summary statistics, ordination and non-hierarchical clustering to investigate these questions.
Field and laboratory methods (include this in your Methods section)
Population samples of the study group for this report (M. adpressus, M. gibberagee, M. hirsutus and M. urceolatus) were collected from 27 sites, and leaf samples for DNA analysis were freeze-dried or dried on silica gel. Additional samples of other species complexes and outgroup taxa were included in the 571 samples that were sent to Diversity Arrays (Canberra, Australia) for reduced-representation sequencing and genotyping via the DArTseq procedure. A total of 186 samples were extracted from the larger dataset to address our research questions. The resulting single nucleotide polymorphiosm (SNP) matrix was filtered using the statistical software R (R Core Development Team, 2020) and the package dartR (Gruber, Unmack, Berry, & Georges, 2018). Loci with repeatability of <97% were excluded, as were those with a call rate (i.e. non-missing genotypes) <95% and minor allele frequencies <0.05. Individuals with call rates less than 90% were also excluded, and ‘secondary’ SNPs within each DArTseq locus were removed, keeping the one with the highest minor allele frequency.
Practical report layout
Write a research report based on your results, in the following format. There should be no Abstract.
• The Introduction should be very brief (max. 250-300 words), but should put the study in context and state the research questions or hypotheses that will be addressed.
• The Methods section should give enough detail for the study to be replicated, but that can include references to other papers for details. Check the 'Field and laboratory methods' (below) section of the 'Topic and analysis overview' for more guidance. You need to state the samples used for each analysis, the origin of the methodology (i.e., the original paper in which it was published, which can usually be found in the software documentation), the software (and version), and the parameters or options used. It should also make it clear how each analysis addresses the research questions or hypotheses.
• In the Results section, show the results with text, figures and tables. Make sure that everything is clearly labelled, and both figures and tables are able to stand on their own; i.e. combined with its caption, each should have enough information to understand the results contained therein. The text should summarise the results and highlight those that are surprising, interesting or are of particular relevance to the hypotheses. All figures/tables must be referred to in the text, but focus on the important points, rather than just writing, for example, "The results of the STRUCTURE analyses are shown in Figure 3".
• The Discussion section should identify the key results, in relation to the research questions and hypotheses, and discuss their significance in the context of the study and more broadly. Any caveats relating to the design or analysis should also be considered. Finish with a concluding paragraph briefly stating the main findings and conclusions, and relating them back to the aims.
References
Cite any sources, including software (R studio), using the referencing style of Molecular Ecology (embedded link for your reference). As noted in the Author Guidelines, you need to look at a recent issue of the journal for reference formats. There is an Endnote Style for the journal, but there is no guarantee that it is correct (you still need to check each reference). N.B. For journal articles, give volume and page numbers, not web addresses. A small minority of journals are online-only, and those are an exception: find an example of an article citing a PLoS journal (PLoS One or PLoS Genetics).

Three Steps
I want you to read this article on a plant that has lived in a sealed glass container, cut off from the outside for decades:
https://www.dailymail.co.uk/sciencetech/article-2267504/The-sealed-bottle-garden-thriving-40-years-fresh-air-water.html
Explain what is wrong with the following statement: “This plant is violating the second law of thermodynamics. Since it is not exchanging materials with its environment it should not be alive at all. In fact, life is a violation of the second law of thermodynamics because living things are closed systems.”
Explain how the terrarium from the article is similar to the Earth as a whole.

GEL- 3.01: Use experimental inquiry to inform problem solving.
Each and every day, you are faced with having to make split-second decisions, and the need to solve random problems that you encounter. In this Assessment, you will create a PowerPoint presentation to explain how you would use the scientific method to solve the following scenario.
Scenario: You have agreed to take care of your friend’s dog; Buddy, while she goes on a trip to Antarctica. On your two-hour trip to take your friend to the airport you get so caught up talking about her upcoming adventure that you do not have any time to ask questions about her new dog (Buddy) who is riding in the backseat. After you drop your friend off, just in time to catch her flight, you drive the two hours back home and realize that your friend accidentally took the dog’s bag with her when she ran into the airport. You realize that you do not have access to your friend’s house and cannot contact her. It is a new dog so there is no one else you can contact that knows its normal routine. You stop at the local pet store and ask the salesperson to help you pick out food and supplies to take care of Buddy for the next few weeks. They send you home with a bag of salmon and potato dry dog food, a few toys, and a dog bed. When you get home you put some of the dog food in a plastic bowl that you had been using to store oranges and lemons. You offer this to Buddy but he refuses to eat his dinner. This puts you in a little bit of a panic since your friend is on a long flight and will then be on a ship to Antarctica so contacting her will be difficult. You take a deep breath and decide that you can try to solve this problem on your own.
A template is provided below to get you started. Additional slides should be added to address all the questions in this assignment and cite your sources. You are welcome to modify this template to suit your needs, being sure to meet the assignment requirements. Make sure your PowerPoint ® presentation addresses the following questions.
What are the steps of the scientific method? List them out and provide a short description in your own words of what happens during each step.
To collect your data, read through the scenario carefully and on a slide provide a list of everything that you know about the situation with Buddy.
Create a testable hypothesis for why Buddy is not eating that is consistent with the data in the scenario: i.e., Buddy is not eating because I did not buy the type of dog food that he is used to. Indicate which pieces of evidence you used to develop your hypothesis.
Outline how you would set up an experiment to test the following hypothesis: Buddy is not eating because I did not buy the type of dog food that he is used to.
Do some research on independent and dependent variables. Identify the independent and dependent variables in your experiment.
List three things that you should keep constant (the same) during your experiment so that they don’t influence the outcome of your experiment.
Identify what you would do if:
The results of your experiment supported your hypothesis.
The results of your experiment did not support your hypothesis.
Explain what you would do in the following two situations:
You know you can contact your friend at some point soon but only for a short time. What three testable questions would you want to ask her to help support or disprove the proposed hypothesis?
Your neighbor comes over to help out with Buddy and poses the following hypothesis: Buddy won’t eat because he feels that his owner is unlucky when she travels and may get hurt. Is this a testable hypothesis? If so, please explain how you would test it. If not please explain why it is not testable in the context of the scientific method.
Information provided on the slides should be brief and bulleted. In the notes section, you must include all of your talking points – exactly as you would present them to your audience. Remember, you want to tell the story during the presentation rather than having your audience reading your slides along with you during the entire presentation. The Academic Success Center’s Writing Center has an excellent resource on
Creating Effective PowerPoint Presentations:
Minimum Submission Expectations:
Include a title slide and a reference slide.
Use images (with citations) as appropriate to create an effective and professional presentation.
On each slide include short descriptions and labels. Do not write out full paragraphs of information on each slide. 18 pt font or larger recommended.
