krebswin: some easier-to-use versions of programs from the text Ecological Methodology by Charles J. Krebs
for Windows 3.1 and '95.

Programs Included:

• Test for Difference in Means by Randomization (RANDCOMP - not from Krebs book) REQUIRES A '386 and Windows to be running in enhanced mode! Tests for a difference in means between samples in two categories when samples from the same blocks are not necessarily independent. Replaces HANNRAND from previous version.
• Calculate distances between samples/species (CALCDIST - like SIMILAR) compute various continuous or binary measures of similarity/distance between samples or species
• Cluster (CLUSTER - not from Krebs book) build a cluster tree from a similarity or distance matrix using various clustering methods such as UPGMA, WPGMA, etc.
• Fit a Distribution (NEGBINOM, POISSON, BINOM) fit a negative binomial, poisson, or binomial distribution to quadrat count data; program can choose "best" fitting distribution . Unfortunately, these programs use a brain-dead way of storing distributions, with storage proportional to the largest count, so they only work for small counts (no more than 180 or so).
• Mark Recapture (JOLLY) Jolly Seber mark-recapture analysis
• Diversity Estimates (DIVERS) various estimates of community diversity indices
• Point Quarter (QUARTER) population estimation by point-quarter sampling
• Line Transect (HAYNE) estimate a population from line transects
• Aerial Census (AERIAL) estimate a population from aerial transects.
• Accumulation and Similarity (not from the Krebs book) calculate species accumulation and turnover with increased sample pooling

You can view the krebswin README.TXT or download SETUP.BAT and KREBSZIP.EXE from http://www2.biology.ualberta.ca/jbrzusto/ftp/krebs/index.html. Save these two files in the same directory, then run SETUP.BAT from Windows File Manager to install KREBS/Win in C:\KREBS. More detailed instructions are available in README.TXT Source code is in the archive source.zip, at the same location.
