TLDR
In this article , the authors propose that Dugesia may have either an ancient origin on a large palaeo landmass, followed by colonisation in different regions before continental fragmentation, or a more recent origin and subsequent transoceanic dispersal.
Abstract
Freshwater planarians may have a wide geographical range despite their assumed low vagility. Found across four continents, Dugesia may have either an ancient origin on a large palaeo landmass, followed by colonisation in different regions before continental fragmentation, or a more recent origin and subsequent transoceanic dispersal. We seek to resolve between these two hypotheses.

Microplate tectonics and environmental factors as distribution drivers in Western Mediterranean freshwater planarians

TL;DR: This article used an integrative approach to understand how palaeogeographical and environmental processes shape species distribution and focus on freshwater planarians as the model system, and used a model system to model the distribution of planarians.

First molecular phylogeny of the freshwater planarian genus Girardia (Platyelminthes, Tricladida) unveils hidden taxonomic diversity and initiates resolution of its historical biogeography

TL;DR: The phylogenetic tree brings to light that Girardia arose on the South American portion of Gondwanaland, from which it, subsequently, dispersed to the Nearctic Region, probably more than once.

First molecular phylogeny of the freshwater planarian genus<i>Girardia</i>(Platyhelminthes: Tricladida) unveils hidden taxonomic diversity and initiates resolution of its historical biogeography

TL;DR: In this paper , a molecular phylogenetic analysis of Girardia is presented, which suggests the presence of two main clades, which are genetically and karyologically highly differentiated.

Phylotranscriptomics interrogation uncovers a complex evolutionary history for the planarian genus Dugesia (Platyhelminthes, Tricladida) in the Western Mediterranean.

TL;DR: In this paper , the authors investigated the evolutionary history of the genus Dugesia in the Western Mediterranean area, based on large data sets of single copy orthologs obtained from transcriptomic data.

Biogeographic–tectonic calibration of 14 nodes in a butterfly timetree

TL;DR: In this paper , the authors used biogeographic-tectonic calibration, with fossil-calibrated ages accepted as minima, to date multiple nodes in the butterfly subtribe Coenonymphina.

RAxML version 8: a tool for phylogenetic analysis and post-analysis of large phylogenies.

TL;DR: This work presents some of the most notable new features and extensions of RAxML, such as a substantial extension of substitution models and supported data types, the introduction of SSE3, AVX and AVX2 vector intrinsics, techniques for reducing the memory requirements of the code and a plethora of operations for conducting post-analyses on sets of trees.

MrBayes 3.2: Efficient Bayesian Phylogenetic Inference and Model Choice across a Large Model Space

TL;DR: The new version provides convergence diagnostics and allows multiple analyses to be run in parallel with convergence progress monitored on the fly, and provides more output options than previously, including samples of ancestral states, site rates, site dN/dS rations, branch rates, and node dates.
