Delineating Species with DNA Barcodes: A Case of Taxon Dependent Method Performance in Moths
PLoS ONE, 2015 The accelerating loss of biodiversity has created a need for more effective ways to discover species. Novel algorithmic approaches for analyzing sequence data combined with rapidly expanding DNA barcode libraries provide a potential solution.

American Journal of Botany, EarlyView.Abstract Premise Uncarina contains 14 species of woody plants endemic to Madagascar. Its occurrence across dryland biomes on the island make it an interesting system to study the diversification of the flora. Methods Using samples of all species and 512 nuclear loci, we reconstructed phylogenetic trees to examine species relationships and assess their ...

NJst and ASTRID are not statistically consistent under a random model of missing data [PDF]
arXiv, 2020 Species tree estimation from multi-locus datasets is statistically challenging for multiple reasons, including gene tree heterogeneity across the genome due to incomplete lineage sorting (ILS). Species tree estimation methods have been developed that operate by estimating gene trees and then using those gene trees to estimate the species tree.

Phylogeny of the Rosidae: A dense taxon sampling analysis
, 2016 Rosidae, a clade of approximately 90 000 species of angiosperms, exhibits remarkable morphological diversity and extraordinary heterogeneity in habitats and life forms. Resolving phylogenetic relationships within Rosidae has been difficult, in large part

Journal of Biogeography, 2015 We sought to reconstruct the biogeographical structure and dynamics of a hyperdiverse ant genus, Pheidole, and to test several predictions of the taxon cycle hypothesis.

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Dysbiosis of the bacterial and fungal microbiome has been increasingly implicated in the pathogenesis of chronic rhinosinusitis (CRS). This study explores the relationship between microbiome and mycobiome biodiversity and type 2 (T2) versus non‐type 2 (NT2) inflammation.

Cross-taxon congruence and environmental conditions
BMC Ecology, 2010 Background Diversity patterns of different taxa typically covary in space, a phenomenon called cross-taxon congruence. This pattern has been explained by the effect of one taxon diversity on taxon diversity, shared biogeographic histories of different ...

CompostBin: A DNA composition-based algorithm for binning environmental shotgun reads [PDF]
arXiv, 2007 A major hindrance to studies of microbial diversity has been that the vast majority of microbes cannot be cultured in the laboratory and thus are not amenable to traditional methods of characterization. Environmental shotgun sequencing (ESS) overcomes this hurdle by sequencing the DNA from the organisms present in a microbial community.

Revista de Ciências da Saúde Nova Esperança, 2017 In 2000, the uninominal taxon capricornia Pleijel & Rouse was established as part of a phylogenetic proposal for the taxon Hesionidae (Annelida, Polychaeta), reported from the Great Barrier Reef, Australia.

Maximum Parsimony on Subsets of Taxa [PDF]
arXiv, 2008 In this paper we investigate mathematical questions concerning the reliability (reconstruction accuracy) of Fitch's maximum parsimony algorithm for reconstructing the ancestral state given a phylogenetic tree and a character. In particular, we consider the question whether the maximum parsimony method applied to a subset of taxa can reconstruct the ...
