Common writing issues April 20, 2011 Zoo 511 General comments • Answer the question! • We didn’t grade too harshly on writing, our main focus was whether you had all components. This will change. • It was evident that some of you did not use your peer review comments. This is a waste of our time and your classmate’s. • Sentences that don’t say anything “Comparing between different communities or populations of fishes is a way in which many types of research can be done”. • It was evident that some of you have not really read other papers. Don’t read them just for facts, read them for style and read them for context. • “The” “These” This” “There was”… read your sentence carefully –are these words needed? If you use this, this what? Always qualify it. General Comments • We will not re-write your paper for you. If we give you a suggestion, or you make one of the mistakes identified in this powerpoint, FIX IT THROUGHOUT YOUR PAPER! • This was not an experiment • “This study” does not expect, think, or do anything. You do. • Don’t capitalize common names • No significance? Include multiple years! • Only use relevant and important tables and figures • Don’t repeat data from a figure in a table. • Be very concise and clear in your writing. • What is the scale/applicability of this study? Quick Grammar Lesson • What is a subject? – Who or what the sentence is about. Find the verb! “There was a slight correlation between brown trout density and reach area” “Clark et al. found that there was a correlation between brown trout density and reach area.” “Figure 1 shows the correlation between brown trout density and reach area” “Brown trout density was positively correlated with reach area” Title • Concise and descriptive – should match with main message of paper • Can include scientific names, not absolutely necessary here (do include them in abstract and first time you mention a species in the main body of the paper) • Effect, Prefer, Influence, etc. Abstract • Not a random collection of sentences from your paper! • A sentence on why we should care (background; relevance to the broader scientific community) • A sentence of your goal/hypothesis • A sentence on what you found / the news/ the results • A sentence on why your findings are cool / what they mean / how they apply to the broader scientific community Introduction • Not a random assortment of facts about your study species. • All paragraphs should lead reader to your hypothesis/question, and all sentences in a paragraph should follow from topic sentence. • Hold the readers hand in a review of relevant literature that sets up the foundation of why this work was done. • Start with general/broad theory (I.e. Predator prey dynamics or foraging theory) • Why is your question important? Why should we care about your species? • Relate broad theory to your topic of interest • Conclude with a statement of your objective (BE SPECIFIC!). Set up what the reader should expect to find in the rest of the paper. Methods • Site description: Where, watershed, temp, species composition (maybe) ~ WDNR website and original handout • Appropriate level of detail: Original: Then, starting at the point furthest upstream, metal rebar was pounded into each side of the creek bank where each of the geomorphic units would be divided. After that, a net with weights along the bottoms was tied to the metal rebar by 3 students, stretching across the width of the river, preventing fish from going downstream. Suggested revision: Block nets were placed at the boundaries between reaches to prevent fish movement between reaches. Methods • Analysis methods • Define geomorphic units • Include calculation of area, cpue, etc. (Did you use average depth of a reach?) • What did you compare? • What tests did you use to compare? Results • Don’t describe figures, and ecology as subject! ORIGINAL: There was a slight correlation with an R2 value of 0.521 between brown trout density and reach area. This can be seen in Figure 2. SUGGESTED REVISION: Brown trout density was positively correlated with reach area (Figure 2, R2 =0.52, p=??). • Biological significance and trends –its okay to say density of suckers was twice as high in pools as in riffles, although this relationship was not statistically significant. • Significant digits –0.1287498 not needed. 0.13 will be fine. Results • Remember to consider validity of statistical tests – Residual plots: mention they were used, but don’t show them in paper – Transformations? • CPUE vs. CPUA vs. CPUV Discussion • Lead your reader to your conclusion. You must know what your conclusion is to do this! • Brief summary of findings in one or two sentences • Why did you find (or not find) what you found (expected)? – Sample size? Sampling Bias? – Violation of statistical test assumptions? • How does this compare to other studies? – Review of similar finding or opposite findings – Differences between our stream and their streams – Within-stream differences vs. across stream differences • Why are your findings or lack thereof relevant and important – How do they fit into the larger body of scientific knowledge? • Future studies, management implications. Tables and Figures • No title • Error bars (say what they are in the caption!) • Most tables are either completely unnecessary or better as a figure • Use symbols on figure to show significant differences • Stand-alone captions – need to be very detailed • Units on axes titles a LN(Ephemeroptera /m2) 4 2 b 0 b -2 Cobble Macrophyte Habitat type Soft Predicted log density of Ephemeroptera in Sparkling Lake across three habitat types. Predicted density is higher in cobble habitats than either macrophyte (p=0.01) or soft habitats (p=0.02). Error bars indicate 95% confidence intervals, letters indicate significant differences at alpha=0.05. Context • Every paragraph in a section should lead reader to your main point of that section. • Every paragraph should begin with a topic sentence. • All other sentences in that paragraph should relate to your topic sentence • Introduction: leading your reader to your hypothesis. – Context = Why did you study what you did, and why should we care? Some background on other studies. – We don’t want to know everything that has ever been written about your study species! • Discussion: leading your reader to your overall conclusion. – Context = what have others found? Why are your results the same/different? What are the broad ecological or management implications of your results? Be concise! ORIGINAL: Likewise, a higher percentage of canopy cover indicates more shading. Furthermore, this shading can help control water temperature. This reduced water temperature is generally indicative of more dissolved oxygen. SUGGESTED REVISION: Canopy cover controls shading in streams, which affects both water temperature and dissolved oxygen. Passive vs. Active Original: It is a high productivity stream though because of steady inflows of warm water from wastewater treatment facilities in Verona. Suggested Revision: The steady inflow of warm water from wastewater treatment facilities in Verona result in a higher level of productivity in Badger Mill Creek. Writing like a Scientist Original: As Europeans began to colonize the New World, they considered it a good idea to bring along some of the organisms that they enjoyed in their homeland. Suggested Revision: Many prevalent “native” species in North America are actually native to Eurasia and were transported overseas as Europeans colonized the New World. Original: Upon first glance at the data there seemed to be a significant correlation between the density of white suckers and the percent canopy cover, however running statistical tests proved that percent canopy cover does not influence density of white suckers (p-value =0.61; R2= 0.02). Suggested Revision: No relationship existed between white sucker density and percent canopy cover (p-value =0.61; R2= 0.02; Figure 2). Clarity Original: These two groups of fishes should be found in different geomorphic units because, but not limited to, the threat of predation. Suggested Revision: We hypothesized small prey fish and brown trout would have significantly different densities within geomorphic units due to predator-prey dynamics. Original: This study examines white sucker and brown trout distributions with stream velocity. Suggested Revision: In this study, I investigate the relationship between stream velocity and the length of brown trout and white suckers. Using references effectively • • • • Every fact needs a citation No citations in abstract Starting sentences with authors name If you are studying the relationship between brown trout density and flow velocity, and you find a study on brown trout density vs. flow velocity, don’t write that they studied it, write what they found! EXAMPLE: “Latzka and Vennie-Vollrath (2010) found a relationship between habitat type and crayfish density”. SUGGESTED REVISION: “Crayfish density is highest in cobble habitats (Latzka and Vennie-Vollrath 2010).
