Good note taking will greatly assist a student when writing his animal research paper. You may want to remind each student to use his own words. Writing Prompts for Animal Research Paper After a student selects her animal, she must answer the questions below. It is important to instruct your child or student to take her time and answer each question thoroughly.
The theory of optimal foraging and its relation to central foraging was examined by using the beaver as a model. Beaver food choice was examined by noting the species of woody vegetation, status chewed vs.
Beavers avoided certain species of trees and preferred trees that were close to the water. No preference for tree circumference was noted. These data suggest that beaver food choice concurs with the optimal foraging theory. Introduction In this lab, we explore the theory of optimal foraging and the theory of central place foraging using beavers as the model animal.
Foraging refers to the mammalian behavior associated with searching for food.
The optimal foraging theory assumes that animals feed in a way that maximizes their net rate of energy intake per unit time Pyke et al. 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.
Herbivores commonly behave as energy maximizers Belovsky and accomplish this maximizing behavior by choosing food that is of high quality and has low-search and low-handling time Pyke et al.
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 The factors associated with the optimal foraging theory also apply to the central place theory. The central place theory predicts that retrieval costs increase linearly with distance of the resource from the central place Rockwood and Hubbell 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 The main objective of this lab was to determine beaver Castor canadensis food selection based on tree species, size, and distance.
Since beavers are energy maximizers JenkinsBelovsky and central place feeders McGinley and Whitamthey make an excellent test animal for the optimal foraging theory. Beavers eat several kinds of herbaceous plants as well as the leaves, twigs, and bark of most species of woody plants that grow near water Jenkins and Busher By examining the trees that are chewed or not-chewed in the beavers' home range, an accurate assessment of food preferences among tree species may be gained Jenkins The purpose of this lab was to learn about the optimal foraging theory.
We wanted to know if beavers put the optimal foraging theory into action when selecting food. We hypothesized that the beavers in this study will choose trees that are small in circumference and closest to the water. Since the energy yield of tree species may vary significantly, we also hypothesized that beavers will show a preference for some species of trees over others regardless of circumference size or distance from the central area.
The optimal foraging theory and central place theory lead us to predict that beavers, like most herbivores, will maximize their net rate of energy intake per unit time. In order to maximize energy, beavers will choose trees that are closest to their central place the water and require the least retrieval cost.
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. Our research area was located along the edge of the pond and was approximately m in length and 28 m in width.
There was no beaver activity observed beyond this width. The circumference, the species, status chewed or not- chewedand distance from the water were recorded for each tree in the study area. Due to the large number of trees sampled, the work was evenly divided among four groups of students working in quadrants.
Each group contributed to the overall data collected. We conducted a chi-squared test to analyze the data with respect to beaver selection of certain tree species.
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.Animal PowerPoint Assignment _ After you are finished writing your report, take the key points from each section (primary sources of energy, habitat, environmental factors, food chain, and adaptations) and create a PowerPoint or Keynote presentation.
