Structure that works Our writers are trained to complete well-structured reports that include abstract, introduction, methods, results, materials, discussion and bibliography. Instructors may ask to either include it in the notebook or bring it separately.
These data suggest that beaver food choice concurs with the optimal foraging theory. Although beaver selection of certain species of trees may be related to the nutritional value, additional information is needed to determine why beavers select some tree species over others.
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. You might be astonished to discover how affordable our prices are in comparison to other companies.
We conducted a chi-squared test to analyze the data with respect to beaver selection of certain tree species.
Other studies suggested that beavers avoid trees that have chemical defenses that make the tree unpalatable to beavers Muller-Schawarze et al. 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.

No avoidance or particular preference was observed for the other tree species. Central place feeders are very selective when choosing food that is far from the central place since they have to spend time and energy hauling it back to the storage site Schoener We wanted to know if beavers put the optimal foraging theory into action when selecting food.
The circumference, the species, status chewed or not- chewedand distance from the water were recorded for each tree in the study area.
You can feel safe and secure because no one will be able to track your paper to our website using search engines. Due to the large number of trees sampled, the work was evenly divided among four groups of students working in quadrants.
This would explain why there was no significant difference in circumference between chewed and not-chewed trees.
There seems to be a fine line between energy intake and energy expenditure in beavers that is not so easily predicted by any given theory.
The central place theory is used to describe animals that collect food and store it in a fixed location in their home range, the central place Jenkins Need an Analytical Chemistry Lab Report?
Since beavers are trying to maximize energy, we hypothesized that they will tend to select some species of trees over others on the basis of nutritional value. We now know that the optimal foraging theory allows us to predict food-seeking behavior in beavers with respect to distance from their central place and, to a certain extent, to variations in tree species.

Lab reports make a major part of each laboratory course, being important contributors into the final grade. The factors associated with the optimal foraging theory also apply to the central place theory. It takes a lot of effort to write competently and professionally.
In case you disapprove of your completed order, you can request free revisions or money-back. In order to maximize energy, beavers will choose trees that are closest to their central place the water and require the least retrieval cost.
For instance, beavers selected large branches at any distance from the water even though cutting large branches may increase energy requirements.Learn lab biology with free interactive flashcards.

If you are taking a general biology course or AP Biology, at some point you will have to do biology lab experiments. This means that you will also have to complete biology lab reports. The purpose of writing a lab report is to determine how well you performed your experiment, how much you understood.
