How to construct an annotated bibliography is explained at:  
An explanation of constructing an '''annotated bibliography''' can be found at: [http://owl.english.purdue.edu/owl/resource/614/01/ | http://owl.english.purdue.edu/owl/resource/614/01/]
Your annotated bibliography should summarize the methods, findings and conclusions of pertinent studies that add to or refute your conclusions about abundance, diversity, and community behavior that you gleaned from your findings. Be sure to construct it using the citation format of the journal ''Cel''. Before you begin to look for studies to include in this bibliography, spend some time analyzing your results and outlining your discussion. A discussion should begin with a brief restatement of the overall topic and then summarize your experimental findings and conclusions. Then each of those conclusions is discussed, comparing your findings to other related studies. Try to find studies that asked the same or similar questions using the same or different methods and get a more complete sense of how your findings fit in the consensus of what's understood about your topic.<BR>


A graphical abstract is a visual representation of the main point of a research report. Because the graphical abstract you will compose for this homework assignment is a visualization of the main take home message of the paper you will write on this semester long project, you must be pretty clear about how the whole paper will e organized and the main messages your want the reader to take away. You have written drafts of most of the sections of this paper, including the introduction that outlines the project, its goals and why the investigation is important. You have also completed a draft of several of the results sections so you should have a pretty clear idea of what you data says about your topic and about many of your experimental questions.  It's time to think about the discussion section of your paper.So what will you discuss? The discussion section of a research report addresses one or more of the following general ideas: what's the larger context for the findings (why is it important or where does this lead?); what are the possible mechanisms behind the findings (how does it work?); what other research helps confirm or call into question the findings in this study (it is so?). Although the discussion is centered on this studies' findings, you need to compare your findings to outside studies. Doing an outline and annotated bibliography is a good way to find and distill information from appropriate outside studies and to start writing the discussion.<BR>

Do you think we (meaning not just you but ANY investigator) has discovered the full extent of the diversity and abundance of a soil community? To discuss this fully, bring in comparative studies on soil samples from other research that come up with similar or different number estimates using other methods to compare to your findings. Bring in both the technological advances as well as any limitations on our ability to know how much and what's there. This is the time to bring in some pyrosequencing studies that did high throughput sequencing and compare the diversity obtained through pyrosequencing to your random sampling of the bacteria by a different culture independent method. Take a look at the paper by Pexito and colleagues using the rpoB gene rather than the 16srRNA gene and include a comparison of other ways of determining phylogenetic diversity. Leave your reader with the sense that although the field has come along way from the recognition of the great plate count anomaly, there is always more to know and discover about the full range of abundance and richness in soil communities. Make this discussion POSITIVE. DO NOT TRASH YOUR METHODS OR YOUR FINDINGS!!!!!! Start your discussion with a summary of what you are sure of: that you ''do'' have conclusive evidence for mind-boggling abundance and significant phylogenetic and metabolic diversity in this soil community and that there is clear evidence for community behavior (co-operation and competition). '''Do not turn a discussion of the advances and limitations of technology in 2011 into a negative discussion about lack of confidence in your findings.''' This is NOT about "sources of error" but about where we are (we being science not Wellesley's BISC209 class) in being able to assess diversity and abundance and how soil communities work as communities.
BE CAREFUL NOT TO TRASH YOUR STUDY'S FINDINGS!!!! Your main take away message is that there is a mindboggling abundance and diversity of soil microorganisms in a community that somehow manage to co-operate and compete to find a niche and to keep the community diverse and healthy. Instead of portraying our (the whole scientific community's) current inability to know the full extent of what's there as a short coming in your study, show your investigation as adding support to the idea that soil microbial communities are a frontier that is largely unexplored and ripe for future important discoveries. Leave your reader with the sense that although the field has come along way from the recognition of the great plate count anomaly, there is always more to know and discover about the full range of abundance and richness in soil communities. Make this discussion POSITIVE.


Now that you have most of the evidence for answering your experimental questions and you know the direction of your discussion of those findings, you will be able to compose the basic structure of a graphical abstract. Although you have most of the test results that you will use to address our investigative goals, you don't yet have your evidence for phylogenetic  diversity back from the sequencing facility. You won't make the "tree" that will be the main visualization of that important aspect of your findings until after we analyze the sequencing data in LAB 9, you may leave a place holder for such an image (if you want to use it in your graphical abstract) and indicate that you will add it later. As you consider possible visualizations of SOME of the data that make your main points, keep in mind that simplicity is important. Do not try to use everything. Do step back and stress the big picture. There is a folder in Resources in Sakai, called Images. Your instructor has uploaded images of the Wellesley Greenhouses including the Tropical room that you may use if you wish. NOTE that these images are available as an OPTION. It is not required to use them or even suggested that anything specific be part of your graphical abstract! <BR>

Discussion Outline, Annotated Bibliography, and Graphical abstract:

Please turn in at the beginning of Lab 9 an outline of your discussion, an annotated bibliography of sources that may be used in your final paper's discussion section, and a graphical abstract summarizing the findings and conclusions to be presented in your final paper.

An explanation of constructing an annotated bibliography can be found at: | http://owl.english.purdue.edu/owl/resource/614/01/ Your annotated bibliography should summarize the methods, findings and conclusions of pertinent studies that add to or refute your conclusions about abundance, diversity, and community behavior that you gleaned from your findings. Be sure to construct it using the citation format of the journal Cel. Before you begin to look for studies to include in this bibliography, spend some time analyzing your results and outlining your discussion. A discussion should begin with a brief restatement of the overall topic and then summarize your experimental findings and conclusions. Then each of those conclusions is discussed, comparing your findings to other related studies. Try to find studies that asked the same or similar questions using the same or different methods and get a more complete sense of how your findings fit in the consensus of what's understood about your topic.

It's time to think about the discussion section of your paper. So what will you discuss? The discussion section of a research report addresses one or more of the following general ideas: what's the larger context for the findings (why is it important or where does this lead?); what are the possible mechanisms behind the findings (how does it work?); what other research helps confirm or call into question the findings in this study (it is so?). Although the discussion is centered on this studies' findings, you need to compare your findings to outside studies. Doing an outline and annotated bibliography is a good way to find and distill information from appropriate outside studies and to start writing the discussion.

BE CAREFUL NOT TO TRASH YOUR STUDY'S FINDINGS!!!! Your main take away message is that there is a mindboggling abundance and diversity of soil microorganisms in a community that somehow manage to co-operate and compete to find a niche and to keep the community diverse and healthy. Instead of portraying our (the whole scientific community's) current inability to know the full extent of what's there as a short coming in your study, show your investigation as adding support to the idea that soil microbial communities are a frontier that is largely unexplored and ripe for future important discoveries. Leave your reader with the sense that although the field has come along way from the recognition of the great plate count anomaly, there is always more to know and discover about the full range of abundance and richness in soil communities. Make this discussion POSITIVE.

Because you have most of your experimental evidence for answering your questions and you know the direction of your discussion from your outline and bibliography, you should be able to compose the basic structure of a graphical abstract. You may revise or add to this draft abstract later when you have all of your data. As you consider possible visualizations that help your reader understand the scope and direction of this study and the data that make your main points, keep in mind that simplicity is important. Do not try to use everything. Do step back and stress the big picture. There is a folder in Resources in Sakai, called Images. Your instructor has uploaded images of the Wellesley Greenhouses including the Tropical room that you may use if you wish. NOTE that these images are available as an OPTION. It is not required to use them nor is it even suggested that they be part of your graphical abstract.

See the definition for a graphical abstract and find examples from published research reports at | http://www.elsevier.com/wps/find/authorsview.authors/graphicalabstracts. Pay particular attention to examples 1,4,5 and #15 (those that are less molecular and more topically ecological).

A graphical abstract is a visual representation of the main point of a research report. Because the graphical abstract you will compose for this homework assignment is a visualization of the main take home message(s) of the paper you will write on this semester long project, you must be pretty clear about how the whole paper will be organized and have in your head the main conclusions that can be made from your data that you have presented in results and explored in your discussion. You have written drafts of most of the sections of this paper, including the introduction that outlines the project, its goals and why the investigation is important. You have also completed a draft of several of the results sections so you should have a pretty clear idea of what you data says about your topic and about many of your experimental questions.
