When submitting a manuscript to the JPACD please consider the following:
- The JPACD is abstracted by the Institute for Scientific Information and in 2006 had an impact factor of 0.933.
- There are no page charges
- Beginning in 2008, the JPACD instituted the following four categories for contributions:
- Full-length research papers of any length
- Short communications/methods papers of 1 or 2 pages when printed
- Reviews of the scientific literature of any length
- Nonrefereed letters to the editor, news of general interest, or noteworthy articles from nonscientists
- Manuscripts may be in English only.
- It is generally recognized that the taxonomy of the fruit-bearing Opuntia is very difficult. To reduce ambiguities, the editors highly encourage authors preparing manuscripts to submit two color pictures of the major fruit types used in the study one-page, scalable file format.
The first picture, at the top of the page, should be a photograph of the entire plant with a ruler to indicate scale. This picture should have sufficient detail to show approximate level of spininess, cladode morphology, and overall plant type.
The second picture should have one uncut fruit and one half of a longitudinally cut fruit laid out on a nonreflective background with a metric ruler along side. This is to show the fruit size, external color, internal color, peel thickness, and seediness.
If the authors can find a photograph with similar characteristics as theirs, already published in the JPACD, they may cite that photograph in lieu of submitting their own photograph. Similarly, if they have previously submitted a photograph of the cactus that is the subject of a new paper, it will be sufficient only to cite the earlier photograph (See JPACD, Volume 9, 2007, p 60, for an example).
- Statistics: Many international journals no longer accept multiple-range tests, such as Duncan’s or Tukey’s. The JPACD editors also look unfavorably upon tests which use pooled variances to test treatments and much prefer the reporting of means and 95% confidence intervals of the individual treatments (not pooled), such as can be obtained from Excel?.
- An editable electronic copy in a standard MS Word file format, is required. A hardcopy of your paper is optional. Please provide an abstract and three to five key words at the beginning of your paper. This is very important for indexing purposes.
- Graphics for figures should be scalable electronic files, or original color or black and white photographs or line illustrations. The JPACD will be printed only in black and white, but will be published on the Internet in color. However, authors should choose colors carefully because light colors, such as yellow, do not appear on black and white prints. Nonscalable graphics are acceptable if they do not exceed the image limit of 6-1/2 inches wide by 9 inches, including the figure title, for a full-page figure.
- In-text citations will be, for example, (Nobel 1996) or Nobel (1996) reported that . . . ., as applicable. The style of references will be the author-date convention, e.g., Nobel, P. 1996. Effects of cold hardiness on Opuntia ficus-indica. Journal of Plant Physiology 30:234-256.
- Report all monetary values in U.S. dollars (US$). Local currency may be reported parenthetically.
- Scientific papers will use metric units. Marketing and/or ranching data may be in English units.
- The JPACD will be published once per year. To facilitate rapid publication of papers, after the manuscript has been accepted it will be placed on our web site within about eight weeks, which includes peer review and production processes.
When about 12 papers have been obtained and put on the web, a hardcopy will be published, closing out that year’s volume. Completion of the volume is expected to occur approximately at the end of each successive year.
