The Landscape Genetics GIS Toolbox contains tools that run in the Geographic Information System software, ArcGIS(®), to map genetic landscapes and to summarize multiple genetic landscapes as average and variance surfaces. These tools can be used to visualize the distribution of genetic diversity across geographic space and to study associations between patterns of genetic diversity and geograph...

Spatial statistical stream-network models are useful for modelling physicochemical data, but to-date have not been fit to macroinvertebrate data. Spatial stream-network models were fit to three macroinvertebrate indices: percent pollution-tolerant taxa, taxa richness and the number of taxalacking out-ofnetwork movement (in-stream dispersers). We explored patterns of spatial autocorrelation in t...

In an extension of the work of Drs. Hunt and Lipo published in Antiquity (2005), I surveyed the prehistoric roads of Rapa Nui (Easter Island) using ArcGIS software and satellite images of the island. A pre-determined set of criteria was utilized, though there was much potential for error with both false positives and negatives. A great deal of progress was made in identifying potential location...

This paper describes how geographic information system (GIS), remote sensing (RS) and Global Positioning System (GPS) technologies were used to plan the collection of entomological baseline data for a tsetse and trypanosomiasis (T&T) elimination project in the Mouhoun river basin in Burkina Faso. Historical data were collated as the background for data analysis. These data were used to define t...

High-resolution images available on Google Earth are increasingly being consulted in geographic studies. However, most studies limit themselves to visualizations or on-screen measurements. Google Earth allows users to create points, lines and polygons on-screen, which can be saved as KML files. Here, the use of R statistics freeware is proposed to easily convert these files to the shapefile for...

UNLABELLED The composition of stable-isotope labelled isotopologues/isotopomers in metabolic products can be measured by mass spectrometry and supports the analysis of pathways and fluxes. As a prerequisite, the original mass spectra have to be processed, managed and stored to rapidly calculate, analyse and compare isotopomer enrichments to study, for instance, bacterial metabolism in infection...

This study describes a method to obtain parameter confidence intervals from the fitting of non-linear functions to experimental data, using the SOLVER and Analysis ToolPaK Add-In of the Microsoft Excel spreadsheet. Previously we have shown that Excel can fit complex multiple functions to biological data, obtaining values equivalent to those returned by more specialized statistical or mathematic...

Software Reliability and its subset, Software Reliability Growth Models, are widely discussed in technical journals and texts. However, actual details on implementation and use of these models are typically lacking. This paper, by an analyst for analysts, summarizes the methods of evaluating SRGM’s for selection as a Software Engineering Environment tool, provides sufficient information to impl...

We present a review of several software products that serve to analyze and solve highly nonlinear—specifically including global—optimization problems across different hardware and software platforms. The implementations discussed are LGO, as a stand-alone, but compiler-dependent modeling and solver environment; its Excel platform implementation; and MathOptimizer, a native solver package for Ma...
