Writing a Biology Review Paper
From the Biology 399 syllabus for
Library Research Methods in the Biological Sciences
Dr. Troy Nash, Presbyterian College Biology Department
Definition of a review
paper
- A review is a comprehensive synthesis
of results from a wide and complex set of studies
- A synthesis of findings rather
than ideas.
- Goal of a review paper is to help readers
make sense of all available information
- Direct quotations rarely found
in reviews. Do Not Use!
Research reviews focus on primary sources
- Original scientific experimentation reported
in scientific journals
- The quality of the review depends largely
on the comprehensiveness of the literature search
Use of secondary sources--textbooks or
review journals (Science, Scientific American, Discover)
- Overview of material--easier to understand.
- Use references for networking, authors
- Get keywords
- Help devise outline
Formatting
the Paper
General Information
- 15-20 pages of text (not including
figures and tables)
- Typed, double-spaced
- 12 point serif type fonts (Times, Times
New Roman, Palatino)
- Margins 1.5" left, 1" top,
1" right, 1" bottom
- Indent eah new paragraph 0.25"
- Must be in a bound folder with a transparent
cover
Title Page
- Center title about 1/3 down the page
in18-point font. Capitalize the first letter of each word except
for articles (a, an, the), conjunctions (and, but, for) and prepositions
(in, on, to)
The Adaptations for Thermoregulation
in Winter Moths
- Center your name 10 lines under the title
in 12-point font
- Center the date of submission date a
double space below your name in 12-point font
- Center the following phrase a triple
space below the date: "a paper submitted to the faculty
of the Department of Biology, Presbyterian College, in partial
fulfillment of the requirements of Senior Seminar, Biology 401"
Pagination
- Number the pages consecutively, beginning
with the title page, which does not have a page number but is
still counted as the first page
- Use only arabic numbers (1, 2, 3, etc.)
- Put the page numbers in the upper right
hand corner
Headings
- Use sparingly
- Make them informative and concise
- Center headings.
- Triple space before the heading and double
space after the heading
- Use 12-point font, but bold
Using Numbers in Paper
- Spell out numbers less than 10
- Do not begin a sentence with a numeral,
even if it larger than 10
- Always use numerals when reporting quantitative
data with a unit: 15 km, 8 g, 5 mL (check McMillan pp. 155-157
for proper abbreviations)
Tables and Figures
- Must be incorporate/insert
tables and figures in the text following the first text citation.
- Cite according to number:
"----as shown in Figure 3."
"----the relationships of the species
(Table 2)."
- Each table and figure should
be self-explanatory.
- Left justify all titles and
legends (single-spaced).
- Put a period after the number
of the figure or table in the title. Figure 1. Survivorship of
Xanthium strumarium seed over a period of 100 days.
- Tables and figures should
be cited according to number, "as shown in Figure 3,"
or "the relationships of the species (Table 2)."
- Make sure to reference figures
in title, if taken from a source.
- Triple space before and after
each table or figure.
Tables
- At least one in paper
- Make sure to know when to
use and when not to use: Use to present many numberical data
or to summarize verbal material from text. Do not use to show
pattern sor trends
- Reference table in preceding
paragraph: Table 1 shows --- or ---- (Table1).
- Number tables consecutively
throughout paper, even if there is only one
- Always horizontally centered
- How to set up
- Title at top, left justified--Table
1. XXXXXXXXXXXXX (Citation 2005).
- Spanner line
- Header
- Subheader
- Spanner
- Data
- Spanner
- Notes
Figures
- Anything not a table is a
figure
- At least one in paper
- Many different types.
- Graphs: Line -- shows trends.
Bar -- quantitative v/s qualitative
- Illustrations
- Diagrams
- Reference figure in preceding
paragraph. Figure 1 illustrates ---
or ---(Fig. 1)
- Number figures consecutively
throughout, but separately from tables
- Always horizontally centered
- How to set up: Figure is on top. If
it is a graph, make sure axes are labeled: independent variable
on X-axis and dependent variable on
Y-axis. If it is an illustration,
include spanner lines
- Title at bottom, left justified
- Figure 1. XXXXXXXXXXX (Citation 2005).
Table of Contents
Scientific
Names
- Always italicized
- Genus capitalized, species
not
- Abbreviate genus name after
the first reference: Querus alba becomes Q. alba
- Avoid using common names
without scientific names. For example, "corn" is not
the same thing in different parts of the world. Give the scientific
name instead of or following the common name: The great white
shark, C. carcharias, is commonly found---- or C. carcharias
is commonly found----
- Do not use articles (the,
a, an) with scientific names
- "Species" is a
collective singular: There is no such word as specie. For
example, "This species is specific to one locale."
- Genera names can be used
alone if you are referring collectively (Some species of Sargassum
grow----)
- Taxonomic levels above the
genus level are capitalized but not italicized: the Chilopoda
(centipedes), Animalia, Chordata, Osteichthyes
- Some taxa have been modified
to become common names, which are not capitalized: lycopsids
from Lycopsida; dipterans from Diptera
Subscripts and Superscripts
- Use superscripts
for degree measurements, ion charges, and mathematical expressions:
36oC, Ca++ or Ca+2, C+
- Use subscripts
for chemical compounds: CaCl2 Fe2(SO4)3
Writing the Paper
Remember the basic outline for a review
paper.
- Title Page
- Title should be specific,
informative, concise
- See pages 89-90 in McMillan
- Abstract
- Short, concise summary of
paper (200-250 words)
- No references
- Center "Abstract"
a double space before paragraph
- Introduction
- Center "Introduction"
above this section
- Review the topic
- Importance and significance.
- Background information, conflicting
views, major lines of thought
- Statement of purpose
- Document and reference sources
- Body of text (topic 1, topic
2, Topic 3)
- Present details of work done
by researchers on topic
- Mention and describe important
techniques, methods, results, and conclusions
- May have headings, but don't
use "Body"
- Develop and follow good topic
sentences
- Coherent, well-blended summation
of all the work you could find that is important to your subject
- Develop a pathway of thought
that leads to conclusions
- Document and reference sources
- Conclusions
- Consolidate ideas, strengthen
relationships between ideas, patterns, tie up loose ends
- Significance of topic
- Make sure you conclude something
- Do not introduce new data,
results
- What is next, future avenues
of research
- Write the paper well in advance of the
due date
- Set it aside and reread it later.
- SAVE, SAVE, SAVE, SAVE (not only on disk,
but on a hard drive somewhere)
- Computer malfunctions will not be accepted
as an excuse for late work
Person
- Most scientific work is written in the
third person, but is written in passive, past tense
- Avoid using pronouns
- Facts and ideas are stated about procedures
and results. Comparative studies were
performed ---- or ---- was observed
over a period of two years.

Unpublished work
General Info: The yolk-sac placenta of the cat shart contains

Research in progress: This
capillary plexus serves to exchange metabolites across the egg
envelope (Wourms, unpublished).
Manuscripts not yet printed: The
cotylephores of Platystacus contain approximately 28.5%
greater surface area for exchange than is availble in Solenostomus
(Wetzel, in press).
