Due to the large number of trees sampled, the work was evenly divided among four groups of students working in quadrants. These data suggest that beaver food choice concurs with the optimal foraging theory. Mean tree distance from the water and mean tree circumference were also recorded.
Discussion Although beavers are described as generalized herbivores, the finding in this study related to species selection suggests that beavers are selective in their food choice. An animal may either maximize its daily energy intake energy maximizer or minimize the time spent feeding time minimizer in order to meet minimum requirements.
The main objective of this lab was to determine beaver Castor canadensis food selection based on tree species, size, and distance. A list of references. Take a look at the best biology lab report template to master this skill.
Here is a short example: The introduction should not be too long and it has to contain the specified terminology related to the subject.
Measurements taken at the study site show that beavers avoided oaks and musclewood Fig. The experiments are intended to reveal the use of any lab apparatus and find out the different components.
The introduction of any biology report states the main idea of its experiment. These studies also suggested that beavers prefer trees with soft wood, which could possibly explain the observed avoidance of musclewood and oak in our study.
The mean distance of 8. Outside the lab, though, you should not discuss your writing of the report with anyone else, other than a tutor at the Writing Center. We conducted a chi-squared test to analyze the data with respect to beaver selection of certain tree species.
In this part, you need to prepare five main sections - the purpose of the experiment, the problem, the methods that were used during your experiment, the results of it, and the conclusion.
This is in accordance with the optimal foraging theory and agrees with our hypothesis that beavers will choose trees that are close to the water.
All writing should be on only one side of the page, and the reports should be stapled in the upper left-hand corner. We conducted t-tests to determine 1 if avoided trees were significantly farther from the water than selected trees, and 2 if chewed trees were significantly larger or smaller than not chewed trees.
What did you learn from it. Our hypothesis was based on the idea that branches from smaller trees will require less energy to cut and haul than those from larger trees. We conducted t-tests to determine 1 if avoided trees were significantly farther from the water than selected trees, and 2 if chewed trees were significantly larger or smaller than not chewed trees.
We conducted a chi-squared test to analyze the data with respect to beaver selection of certain tree species. Include a detailed explanation of unexpected results when needed, and when searching for possible options, consider the following: Many students tend to blame themselves for unexpected results, but they are not always at fault.
Writing your conclusion and discussion When writing this section, you need to summarize the findings of your experiment, and this means all important details should be interpreted and discussed in full.
This finding agrees with our hypothesis that beavers are likely to show a preference for certain tree species. This is in accordance with the optimal foraging theory and agrees with our hypothesis that beavers will choose trees that are close to the water.
Don't hesitate to ask if you have questions about form or content. In order to corroborate our findings, we suggest that this study be repeated by others. Are all of your working assumptions correct. An abstract can come after the title of your lab report or at its beginning, but you should write it only after completing the whole assignment, and that's because you'll have a clear idea of what to include and discuss in it to get higher grades.
Our research area was located along the edge of the pond and was approximately m in length and 28 m in width. The purpose of this lab was to learn about the optimal foraging theory.
For instance, beavers selected large branches at any distance from the water even though cutting large branches may increase energy requirements. Did you find any errors. The catecholase activity of enzymes has been measured through its rate of absorption in a spectrophotometer, with the use of light that has a nm wavelength.

Carey Booth Box Biology 2 February Lab instructor: Ned Knight Lab day: Friday. SAMPLE LAB REPORT. The Optimal Foraging Theory: Food Selection in Beavers Based on Tree Species, Size, and Distance Laboratory 1, Ecology Abstract. Citation/References: All references used should be included at the end of your lab report.
That includes any books, articles, lab manuals, etc. that you used when writing your report. Example APA citation formats for referencing materials from. The first page of a lab report should be a title page with the title of the report, your name, the date, the course (e.g., Biology ), and your lab partners.
There should then follow text that is a minimum of two pages and a maximum of five double-spaced, typewritten pages in length (tables, figures, and references do not count in this total).

In this Article: Article Summary Creating Your Title Page Writing Your Introduction Listing Material and Methods Explaining Results Drawing a Conclusion Crediting References Formatting Your Report Community Q&A Biology lab reports have a specific format that must be followed to present the experiment and findings in an organized manner%(40).
Sep 08, · Write the lab report in the passive voice. Science writing focuses on presenting data and results and should use clear language with no ambiguity. Lab reports should describe the experiments and methods in an objective manner which any other researchers could follow exactly%(7).How to write a biology lab report example
