  • Program: Suburban Deer Model
    Author(s): Dwayne Etter, Tim Van Deelen
    Version: 2.0
    Last revised: May 2001
    Size: 7 KB
    OS: Windows 3.1, Windows 95, 98
    Archive format: zip

    Description: Data from study and management of suburban deer populations in DuPage and Cook Co., Illinois provide the foundation for the development of an empirical suburban deer population model using Stella 5.0 software. The model treats male and female populations as discrete, because of their different survival, emigration, and reproductive potential. Density-dependent recruitment rates were incorporated to account for changes associated with fluctuating deer-densities. Sensitivity analysis was used to test the ability of different male and female removal strategies to achieve desired deer densities on an annual culling schedule.

  • Program: Bandops
    Author(s): B. H. Powell
    Version: unknown
    Last revised: unknown
    Size: 427 Kb
    OS: DOS
    Archive format: zip

    Description: Bandops was written to maintain band inventories, enter and check banding data, print banding schedules, report accomplishments and manage encounter data. (more about Bandops)

  • Program: Band Analysis System
    Author(s): Paul Geissler
    Version: unknown
    Last revised: unknown
    Size: 1.5 Mb
    OS: DOS
    Archive format: zip

    Description: The Band Analysis System is a tool for those who analyze banding data. It selects banding and recovery records based on the species, age, sex, banding and recovery dates and locations and permit numbers as well as on codes for condition, status, how obtained and who and why reported.

  • Program: BIO-DAP
    Author(s): Gordon Thomas
    Version: unknown
    Last revised: February 2000
    Size: 769 Kb
    OS: Windows 3.1/95/98/NT
    Archive format: zip

    Description: Bio-dap calculates diversity indices corresponding to those presented by A. E. Magurran in "Ecological Diversity and its Measurement" (Princeton Univ. Press). Calculations include: rarefaction, geometric series, log series, truncated log normal, broken stick, Q statistic, Shannon diversity index, Brillouin index, Simpson's index, McIntosh's index, Berger-Parker index, jack-knifing, Pielou's pooled quadrat, beta diversity, similarity measures.

  • Program: Biotools
    Author(s): John Hanks
    Version: unknown
    Last revised: unknown
    Size: 68 kb
    OS: Windows ((Excel macro)
    Archive format: zip

    Description: Biotools is an Excel macro that allows you to select an input range (your dataset) and describe it (give some input as to how it is set up) and then have the macro calculate all eight (at this time) diversity indices, put them on the selected output range or a new sheet and optionally output SAS ready files (a dataset and a macro to read the dataset).

  • Brownie (Gary White, zip archive, 101 kb, DOS)
    Brownie computes survival estimates from banding (ringing) recovery data from young and adult animals.

  • Capture (Gary White, zip archive, 166 kb, DOS)
    Capture computes tests to select a model from 11 possible models, and estimates population size for capture-recapture data on closed populations. (more about Capture)

  • CAS5demo (Bloom, zip archive, 1026 kb)

  • Comm (Dieter Piepenburg, zip archive, 96 kb, DOS)
    COMM has been developed to assist ecologists in the analyses of medium-sized species-station-tables commonly generated in ecological field investigations. (more about Comm)

  • Contrast (James E. Hines, zip archive, 40 kb)
    Sauer and Williams (J. Wildl. Manage 53:137-142, 1989) recently described a general procedure for the comparison of several rate estimates that incorporates associated variance and covariance estimates; this program implements this method. The program will be used primarily for the analysis of survival rates; however, the method can be used for tests about any rates (or other parameters) for which estimates and their associated variances and covariances are available. (more about Contrast)

  • Estimate (Gary White, zip archive, 84 kb)
    Estimate computes survival estimates from banding (ringing) recovery data from adult animals only.

  • Jolly (James E. Hines, zip archive, 99 kb)
    Jolly computes survival rate, population size, and immigration rate estimates from capture-recapture data. The user is allowed to choose different features of the model such as the presence of death and immigration. A goodness-of-fit test is also provided to determine the appropriateness of a model. more about Jolly)

  • Jollyage (James E. Hines, zip archive, 81 kb)
    Jollyage computes survival rate, population size, and birth/immigration estimates for an age-stratified capture-recapture data set using a stochastic model developed by S. L. Stokes. The program assumes the population to be stratified onto young (who remain young for one sampling period) and adult. The adult estimates of survival rate, population size, and birth/immigration, and young estimates of survival rate are computed for each sampling period. (more about JollyAge)

  • Monitor (James P. Gibbs, 166 Kb, for Intel based PCs)
    This software estimates the statistical power of population monitoring programs relative to (1) the number of plots monitored, (2) the magnitude of counts per plot, (3) count variation, (4) plot weighting schemes, (5) the duration of monitoring, (6) the intervalof monitoring, (7) the magnitude and nature of ongoing population trends, (8) the significance level associated with trend detection,and several other factors. See either the html version or WordPerfect 5.1 version of the Monitor manual.

  • Populus (real-mode) (Don Alstad, self-extracting archive, 726 kb, v 3.4, February 1994)
    The "real-mode" version of Populus will run on any Intel-based computer, including the XT class with an 8088 chip. The "protected-mode" (808 kb) version is for use on machines with a 286 or later microprocessor and a minimum of 2 MB RAM. (more about Populus)

  • Puma (Paul Beier, self-extracting archive, 82 kb, v 1.0, for DOS, October 1992) predicts the risk of extinction in cougar populations under various development scenarios. Three factors (habitat area, possibility of immigration, and mortality rates) can directly be set as driving variables. (Puma home page, more about Puma)

  • Release (Gary White, zip archive, 651 kb)
    Release computes survival estimates and goodness-of-fit tests for a large class of survival experiments based on capture-recapture of marked populations.

  • Surge (zip archive, 215 kb)

  • Uindex4S (Michael C. Bell, self-extracting archive, 135 kb)
    UINDEX4 is a DOS executable program for the estimation of population size index numbers by the Underhill (1989) method. (more about Uindex4)
