We introduce Cost Distance FISHeries (CDFISH), a program to simulate gene flow in complex riverscapes under a wide range of environmental scenarios for aquatic organisms. The spatially-explicit program simulates changes in subpopulations and genotypes through time as functions of individual-based movement, reproduction, mortality, and dispersal through migration and straying on a continuous riverscape. This program is a valuable tool for the study of landscape genetics for aquatic species living in complex stream environments.
Among the most important and urgent problems for society and conservation ecology is maintaining ecosystem integrity, which requires maintenance of population connectivity to maintain healthy and viable populations. To address this need, we introduce UNIversal CORridor network simulation (UNICOR), a species connectivity and corridor identification tool.
CDPOP is a spatially-explicit simulator of gene flow in complex landscapes to explain observed population responses and provide a foundation for landscape genetics. This program can be used to increase our understanding about the effects of life-history and differential models of landscape resistance on the genetic structure of populations in complex landscapes.
GARM is a recent addition to the CEL software package. GARM uses a genetic algorithm to search the parameter space of landscape resistance maps to determine the set of weights that best match the observed genetic structure. GARM is still in testing and will soon be available for download.
