When examining various landscapes and geographical areas, a candid assessment of habitat preference among various species is essential. There was no research activity beyond this perimeter. Since beavers are energy maximizers JenkinsBelovsky and central place feeders McGinley and Whitamthey make an excellent test animal for the optimal foraging theory.
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.
For a certain population of species in an environment different from the original, a certain number is compromised to compensate the impact. In the discussion, the level of agreement between the conclusions of the present study and earlier work is discussed.
Other information is also needed about predatory risk and its role in food selection. We opted to utilize clustering method in order to place sites containing similar species into the same class or group.
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.
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. Introduction In this lab, we explore the theory of optimal foraging and the theory of central place foraging using beavers as the model animal.
Choose one of the dozen available payment methods Relax and enjoy yourself 3 Enjoy your life Everything is clear here; you can just enjoy your spare time or do more important things while we are working on your paper. 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 Also label each of the sections of the report beginning with the Introduction.
In the introduction, you stated your hypothesis, and in this section, you discuss the degree of support for the hypothesis. As distance from the water increases, a tree's net energy yield decreases because food that is farther away is more likely Ecology lab report increase search and retrieval time.
In addition to the specifics of field and lab procedures used, the methods section also includes a description of the study site and the statistical analyses employed. Ecology lab report references should include the authors' names, year of publication, book title, and name and location of the publisher.
If two students turn in substantially similar lab reports, they will share the grade. Overall, animals showed a large percentage on the disturbed index, and the trend was based on the site encountered. This is the most important set of skills necessary for research.
This lab gave us the opportunity to observe how a specific mammal selects foods that maximize energy gains in accordance with the optimal foraging theory. Also label each of the sections of the report beginning with the Introduction. In contrast to scatter plots, the data in bar graphs are represented as vertical bars.
By convention, genus and species names are always underlined or italicized e. Foraging refers to the mammalian behavior associated with searching for food. Write in complete, grammatically correct sentences and paragraphs; correct spelling and punctuation are expected.
Write out long phrases the first time they appear and abbreviate subsequently e. Use the references from the journal Ecology as a guide for the format for complete references.
The results derived from cluster analysis was essential to elaborate the various vegetation types within the study area. Credit must be given for ideas even though direct quotes are rarely used. At the end of the paper, give complete references for all works cited in the report.
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 No particular preference or preclusion was observed for particular species.
This includes ideas from textbooks, lab handouts, etc. Also include the implications of your results for organisms in the real world. Use the references from the journal Ecology as a guide for the format for complete references. 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.
This is the most important set of skills necessary for research. When calculating the true population parameter, it will be calculated from all the number of individuals found by the quadrate method involving both disturbed and grassland. Graphs must be clearly labeled with x-axis and y-axis titles and a descriptive caption.
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.AP Biology Ecology Lab - Free download as PDF File .pdf), Text File .txt) or read online for free.5/5(4).
SAMPLE LAB REPORT. The Optimal Foraging Theory: Food Selection in Beavers Based on Tree Species, Size, and Distance Laboratory 1, Ecology Abstract. 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. Therefore, ecology is actually the study of living things in their home environment or habitat.
In this experiment we are going to study the ecology at the sea shore. Sea shore is a unique area in which it is periodically submerged5/5(1). Therefore, ecology is actually the study of living things in their home environment or habitat.
