Detection and Polarization of Introgression in a Five-taxon Phylogeny
bioRxiv, 2014 In clades of closely related taxa, discordant genealogies due to incomplete lineage sorting (ILS) can complicate the detection of introgression. The D-statistic (a.k.a.

The generalized Robinson-Foulds metric [PDF]
arXiv, 2013 The Robinson-Foulds (RF) metric is arguably the most widely used measure of phylogenetic tree similarity, despite its well-known shortcomings: For example, moving a single taxon in a tree can result in a tree that has maximum distance to the original one; but the two trees are identical if we remove the single taxon.

PLoS ONE, 2014 Species distributed across vast continental areas and across major biomes provide unique model systems for studies of biotic diversification, yet also constitute daunting financial, logistic and political challenges for data collection across such ...

Axiomatic opportunities and obstacles for inferring a species tree from gene trees [PDF]
arXiv, 2014 The reconstruction of a central tendency `species tree' from a large number of conflicting gene trees is a central problem in systematic biology. Moreover, it becomes particularly problematic when taxon coverage is patchy, so that not all taxa are present in every gene tree.

Applications in Plant Sciences, EarlyView.Abstract Premise The occurrence of different microorganisms on aquatic macrophyte fossils suggests that biofilm microbes may facilitate leaf preservation. Understanding the impact of microorganisms on leaf preservation requires studies on living plants coupled with microbial amplicon sequencing.

Phytoplankton Hotspot Prediction With an Unsupervised Spatial Community Model [PDF]
arXiv, 2017 Many interesting natural phenomena are sparsely distributed and discrete. Locating the hotspots of such sparsely distributed phenomena is often difficult because their density gradient is likely to be very noisy. We present a novel approach to this search problem, where we model the co-occurrence relations between a robot's observations with a Bayesian

mvh: An R tool to assemble and organize virtual herbaria from openly available specimen images
Applications in Plant Sciences, EarlyView.Abstract Premise Recent advances in imaging herbarium specimens have enhanced their use in biodiversity studies. However, user‐friendly tools that facilitate the assembly of customized sets of herbarium specimen images on personal devices are still lacking.
