COMMUNITY ANALYSIS PACKAGE (CAP)
A program to search for structure in ecological community data which is
easy to use, produces quality output and is affordable
CAP is a Windows 95/98 program that offers a range of analytical
techniques commonly used by community ecologists. Researchers in other
fields such as palaeontology, archaeology and the social sciences also
use many of these methods. Programs to carry out many of these
techniques have long been available, but, they are often difficult to
use as they were written for main frame computers or PC's using DOS and
they frequently have little or limited graphical output. CAP has been
designed for ease of use on PC's running under Windows 95/98. Data can
be organised using standard Windows programs such as Excel and the
output from CAP is displayed, exported and printed using standard
Windows techniques. This results in a program that is easily used by
both students and professional ecologists. It is particularly useful for
ecological teaching because it allows students to quickly enter data,
try different transformations and explore a range of methods within a
familiar Windows setting.
Methods available within CAP include
- Principal Components Analysis.
- Reciprocal Averaging.
- Detrended Correspondence Analysis (DECORANA).
- 7 Agglomerative cluster analysis methods.
- 26 Similarity & distance measures
- Divisive cluster Analysis.
- Two-Way Indicator Species Analysis (TWINSPAN).
- Association analysis.

- An attractive and intuitive user interface.
- Extensive help system.
- Easy data importation from spreadsheets.
- A wide range of data transformations.
- Extensive data set statistics.
- High quality graphical output.
- Dendrograms that can be modified and exported.
CAP is ideal for
- Community ecology research.
- Applied ecology.
- Consultancies undertaking ecological assessments.
- Post and undergraduate teaching.
- Ecologists with little mathematical background.
Within CAP the data is held as raw and working data grids which
typically hold samples as the columns and species as the rows. The raw
data grid can be edited and the working data can be transformed in a
wide variety of ways. If desired, the program will remove samples or
species that are represented by too many zeros and standardise the data
in a variety of ways. The maximum size of the data set is 500 samples by
Once the working data set has been prepared the analysis to be
undertaken is chosen from the drop-down menus arranged along the top bar
of the program. The output is arranged in a tabbed notebook. Some tabs
will hold text or the results of calculations and others graphs or
dendrograms. Each page of the note book can be printed or in the case of
graphical output exported in a variety of formats.
Pisces Conservation Ltd is a small company of professional ecologists
and programmers who are familiar with the needs of ecologists and offer
full support to users of their programs. CAP shares the same data
structure with Species Diversity and Richness
