Useful software

Review of wildlife ecology software (~50).
Another list.

Resource Selection for Windows:
RSW is a 32-bit Windows program for analyzing preferences or avoidances from a habitat/cover types study, feeding trials, etc., using five methods. The methods include the Neu et al. (1974), Johnson (1980), Friedman (1937), Quade (1979), compositional analysis (Aebischer et al. 1993), and compositional analysis on ranks (Bacon-Shone 1992). The first 4 methods have been the subject of intensive study by Alldredge and Ratti (1986, 1992). Cherry (1996) recommended using Bailey intervals for the Neu method instead of the binomial confidence intervals. Both intervals are computed in RSW.
[ The compositional analyses are not computed using randomizations, as recommended by Aebischer et al. (1993), but see the following Excel macro) ].

Compositional Analysis Excel Tool for Version 5.0 :
This tool for Compositional Analysis with Randomisation testing was written by Peter G. Smith of Smith Ecology Ltd.. The tool was first used, in an earlier version, by Smith (2000). The copyright in this software is held by Smith Ecology Ltd. The software must not be copied or distributed without the permission of Smith Ecology Ltd. Version 7.0, Version 2002 or a compatible version of the Microsoft Excel spreadsheet package is required to be able to use this compositional analysis tool. The tool comprises an application specific Excel Add-In (the file “CompAnal x_x.xla”) and an Excel workbook (the file “Compositional Analysis x_x.xls”). The Add-In is accessed as a library item by code in the Excel workbook to perform the analysis on data you copy into specific worksheets of the workbook. Compositional Analysis is a technique that uses MANOVA to analyse two sets of data in which variables are represented as proportions. It is used to determine the statistical significance of differences and the rank order of differences between the variables.

Animal Movement ArcView 3.x extension:
Animal Movement is an ArcView extension that contains a collection of over 40 functions specifically designed to aid in the analysis of animal movement. This data could be collected from radio tags, sonic tags, Argos satellite tags or observational data. The program is designed to implement a wide variety of animal movement functions in an integrated GIS environment. The program also has significant utility for analyzing other point phenomena. This program requires the ESRI program Spatial Analyst!

Hawth's Analysis Tools for ArcGIS:
Hawth's Analysis Tools is an extension for ESRI's ArcGIS (specifically ArcMap, ArcGIS 8.x and 9.x). It is designed to perform spatial analysis and functions that cannot be conveniently accomplished with out-of-the-box ArcGIS. Most of these analysis tools have been written within the context of the ecological applications I am involved in (movement analysis, resource selection, predator prey interactions and trophic cascades). However, they have been created in such a way as to be as broadly applicable as possible such that I hope people from many disciplines will find use in this set of tools. There are three types of tools in this kit. First, there are simple tools that automate mundane tasks (e.g. deleting many fields at once from a table). These will likely be useful to anyone. Second, there are tools that are designed to be part of an analysis workflow. For instance, random point (or stratified random point) generation, minimum convex polygon delineation, summarizing raster layers in various ways, etc. These too are likely to be useful to many people. Finally, there are tools that target specific, ecology related analyses (for instance, various movement model applications). These will likely only be of interest to ecologists. Specific detail of the tools can be found on the Tools page.


HRE: The Home Range Extension for ArcView
Created by Arthur R. Rodgers and Angus P. Carr, Ontario Ministry of Natural Resources, Thunder Bay, Ontario, Canada The HRE contains software that extends ArcView to analyze home ranges of animals. The ability to use large data sets and carry out all required home range analyses within a single software environment were our primary reasons for developing the Home Range Extension (HRE) for the ArcView GIS. The program has been written for novice GIS users who already understand basic wildlife telemetry issues and who are familiar with the concept of a "home range". Since the HRE was originally developed for use with LOTEK GPS collars, it has a direct import filter for their data files. The HRE also provides direct import of data from Service Argos DCLS files, dBASE files, or ASCII text files. An important feature of the HRE is the "Moose On A Leash" (MOAL) data animation tool that follows an animal's path as it moves from point to point. Point data can be used to calculate average distance moved between fixes, average elapsed time between fixes, speed of movement, total distance moved in a given period, or home range polygons. The HRE currently includes 2 home range analysis models: minimum convex polygons (MCPs) and kernel methods. Because different computer software programs may produce large differences in home range estimates based on these models, the HRE includes most of the options offered in earlier programs for calculation of estimators and values input for various parameters. There are several different ways to automatically generate %MCPs in the HRE. The HRE includes both fixed and adaptive kernel methods. Both Schoener's index and the Swihart and Slade index are calculated in conjunction with kernel analyses. Determination of habitat types used by an animal is relatively straightforward in a GIS using the geometric intersection of "the habitat" with "the area used by the animal" as described by a polygon resulting from one of the MCP or kernel methods. The user should be able to perform all the analyses of their point data within ArcView and the HRE.

http://www.titley.com.au

Televilt Sweden (we had several problems with receivers and moisture)
http://www.televilt.se

Antennas, the very small and handy H-Antennas are recommended WiMo, but also the collabsible antennas from Titley (see above)

Have a look at this feedback at BioTelemetry list in November 2004:
"MF: Thanks for the responses to my questions about reliable telemetry equipment manufacturers. Several people asked me to post a summary so I am providing that here. To make it simple I have just noted the number of positive (P) or negative (N) responses I received about the various manufactures mentioned." (in green the experience from SWILD)

Temperature loggers
Have a look at the tiny, relative cheap ibuttons.
(All temperature and humidity models. We first used DS1921G-F5 thermochron ibuttons (2048 measurements: 1 record /h from 85 days) with DS9093F Flanged Fob, in 2008 we moved to the high capacity model DS1922L-F5#. These models can take 8192 hourly measurements in a period of 350 days.
For download you need one DS1402D Blue Dot Receptor best with a DS9490R USB Port Adapter. Ev. you find both together in a starter kit with a thermochron ibutton.
Use the online software to view data.
The free software should be here or here (ibutton.com is an awful site, sorry). How to import data into Excel.


Tinytalk loggers from Gemini.

camera traps (Fotofallen)
We are testing at the moment the new Moultrie IR 60 camera trap,
, thanks to Markus Jenny & Jörg Tilmann (available best from Cabelas, Moultrie itself has very bad service)
Trail Master (in Europa by AE)

Marking (of small mammals)

Cement / glue to attach transmitters (e.g. to bats)
Once Skinbond: (not available any more! After the composition had changed (old Skinbond to New Skinbons) there were various feedbacks about the glue being still stuitable. No question any more because it is not produced any more
).

Currently the best information is provided by Holohil:

2009: see the papers from Albus & Carter 2007? and Carter et al. 2009:
recommendation of Perma-Type Surgical Cement, which should be available here.

April 2007: A german product which was sucessfully used on V. murinus bats (transmitters retained 2-3 weeks): Sauer-Hautkleber - Original.
Switzerland

March 2007: Holohil recommends Torbot Bonding Cement (not any more - see above)

A nice replacement for SkinBond? (thanks to Igor for beta testing): the glue did hold >6 days in Plecotus.
However, my tests were not very promising: it could work for smaller, nice behaving bat species but certainly will not hold for wild boars as Myotis myotis... Any other experiences?
Company Fing'rs, Wimp'rs, Product ID 70034, available ~worldwide here (Switzerland).

Two other recommendations (10-40d on small birds, text only in German, not tested myself):
Der gute und billigere Leim heisst Histoacryl und wird von der Firma B.Braun vertrieben. Eine Ampulle von 0,5 ml reicht für etwa 10 Klebungen. Kosten ca. 20.- pro Ampulle, lieferbar in Packungen zu 5 oder 10 Ampulle, 0.2 oder 0.5 ml Ampullen. Geöffnet kann er noch etwa 2-3 Tage verwendet werden. Er trocknet sehr schnell.
Der teurere ist von Johnson & Johnson und heisst Dermabond. Er reicht kaum für 4 Klebungen und trocknet schnell, kann deshalb eigentlich nur am 'Oeffnungstag' gebraucht werden, denn er trocknet im geöffneten Behälter sehr schnell ein und kann dann kaum mehr herausgepresst werden (Dank an die Vogelwarte!)

This is their info from March 2004 (pdf)

light tags or glow sticks from USA

age analysis
cementum aging by Matson Lab

High altitude bat echolocation monitoring
Impact assessment of wind energy sites: we used zeppelins from Mediazepp (Model 4.5m long, 900 EUR). We used 6.7 m3 helium (ca. 250 EUR?). Absolutely necessary: second stronger security line, enormous forces with winds at high altitude. Marking lights (Funkbefeuerung): Luxeon Emitter, blinking red (44 lumen) in sufficient distance to recording unit.Licence from "aviation civile" was necessary in France.

DNA storing

Not really marking, but tissue sampling in bats:
Biopsy Punches


Storing museum samples (thanks Manuel Ruedi)
:
Evidement, il faut garder à au moins -20°C les cadavres frais, et après, les mettre dans de l'Ethanol 80-95% . Attention, PAS de l'ethanol mélangé avec du MEC ou autre dérivé de methanol (c'est en fait l'acool le plus utilisé en Museum!), car cela dégrade rapidement l'ADN. Mettre les échantillons dans de l'ethanol 80%, avec 1% d'isopropanol (qui est OK pour l'ADN).
