Special focus lies on determining the processes forming and maintaining populations of the free-living form are and how this influences their genetic diversity. Within this thesis, I assess the genetic diversity of two variant forms of the perennial, marine, brown alga Fucus vesiculosus (Fucaceae, Phaeophyceae) and their potential ecological differences within the Baltic Sea. Moreover, traditional taxonomically recognized species often conflict with evolutionary or ecologically relevant units, whilst the ecological significance of intraspecific variants are also often overlooked. Genetic diversity is important in defining a species adaptive potential, yet is still a largely neglected aspect of biodiversity. The most basic element of biodiversity is genetic diversity. īiodiversity represents the variability within and between ecosystems, species and individuals and is critical for ecosystem functioning. GenoDive is available for computers running Mac OS X 10.7 or higher and can be downloaded freely from. In addition, GenoDive makes it possible to run several external programs (LFMM, Structure, Instruct, and vegan) directly from its own user interface, avoiding the need for data reformatting and use of the command line. A unique feature of GenoDive is that it can also open datasets with non‐genetic variables, for example environmental data or geographical coordinates that can be included in the analysis. ![]() The different types of analyses offered by GenoDive include multiple statistics for estimating population differentiation (φST, FST, FʹST, GST, GʹST, GʹʹST, Dest, RST, ρ), AMOVA‐based K‐means clustering, Hardy‐Weinberg equilibrium, hybrid index, population assignment, clone assignment, Mantel test, Spatial Autocorrelation, 23 ways of calculating genetic distances, and both PCA and PCoA. One major feature of GenoDive is that it supports both diploid and polyploid data, up to octaploidy (2n=8x) for some analyses, but up to hexadecaploidy (2n=16x) for other analyses. ![]() Furthermore, GenoDive seamlessly supports 15 different file formats for importing or exporting data from or to other programs. GenoDive has an intuitive Graphical User Interface that allows direct manipulation of the data though transformation, imputation of missing data, and excluding and including individuals, population and/or loci. This version presents a major update from the previous version and now offers a wide spectrum of different types of analyses. 3.0, is a user‐friendly program for the analysis of population genetic data. ![]()
