Community Analysis Package
diversity and richness
 version 2 offers considerable improvements over version 1.
Existing users will immediately note the redesigned menu system and improved
graphics, data input and printing. Probably the greatest recent improvements
have been the extended range of methods and statistical tests on offer. The
program offers all the analytical tools that a general ecologist needs for analysing
and comparing the diversity of communities. Because most users have now
moved to Windows 95/98 version 2 is not available for Windows 3.1. Version 1 of
the program is supplied for 3.1 users.

 is a Windows  program that offers a range of graphical and analytical
techniques commonly used by biologists, geologists and archaeologists for the
analysis of circular data.
Axis implements the principal graphical methods and statistical tests described by
Fisher (1993) in 
Statistical Analysis of Circular Data
. Periodic data of many kinds
can be represented and analysed using the methods available within Axis.
While compass bearings are the most obvious examples of circular data, other
examples would be the time of events over a 24 hour period and the occurrence
of activity over the lunar cycle.
Available plots within Axis include linear, circular and angular histograms, and
optional smoothing by Fast Fourier Transform. Tests include: correlation between
samples, uniformity or randomness, and specified mean direction. Simulated data
sets can be created conforming to various distributions.
