Polyhedral geometry of Phylogenetic Rogue Taxa [PDF]
arXiv, 2010 It is well known among phylogeneticists that adding an extra taxon (e.g. species) to a data set can alter the structure of the optimal phylogenetic tree in surprising ways. However, little is known about this "rogue taxon" effect. In this paper we characterize the behavior of balanced minimum evolution (BME) phylogenetics on data sets of this type ...

A Simple Explanation for Taxon Abundance Patterns [PDF]
Proc. Nat. Acad. Sci. 96 (1999) 15017, 2000 For taxonomic levels higher than species, the abundance distributions of number of subtaxa per taxon tend to approximate power laws, but often show strong deviationns from such a law. Previously, these deviations were attributed to finite-time effects in a continuous time branching process at the generic level.

An Arrow-type result for inferring a species tree from gene trees [PDF]
arXiv, 2013 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. Here, we list four desirable properties that a method for estimating a species

On the structure of psychoeducational constructs: taxometric analysis and epistemological implications [PDF]
Frontiers in PsychologyTaxometric analysis (TA) is a technique designed to elucidate the structure of a psychological construct, specifically determining whether the latent variable is categorical (taxon) or dimensional.

Taxon- and Site-Specific Melatonin Catabolism
Molecules, 2017 Melatonin is catabolized both enzymatically and nonenzymatically. Nonenzymatic processes mediated by free radicals, singlet oxygen, other reactive intermediates such as HOCl and peroxynitrite, or pseudoenzymatic mechanisms are not species- or tissue ...

Increased Taxon Sampling Greatly Reduces Phylogenetic Error [PDF]
Systematic Biology, 2002 Several authors have argued recently that extensive taxon sampling has a positive and important effect on the accuracy of phylogenetic estimates.

A new semi-slug of the genus Microparmarion from Brunei, discovered, described and DNA-barcoded on citizen-science 'taxon expeditions' (Gastropoda, Stylommatophora, Ariophantidae) [PDF]
Biodiversity Data Journal, 2023 During citizen-science expeditions to the Ulu Temburong National Park, Brunei, several individuals were collected of a semi-slug species of the genus Microparmarion that, based on morphology and in-the-field DNA-barcoding, was found to be an undescribed ...

New records of moth flies (Diptera, Psychodidae) for the Dutch Fauna [PDF]
Biodiversity Data Journal, 2023 Prior to this study, the moth flies in The Netherlands were represented by 61 species. Our findings derive from a citizen-science expedition in the Vondelpark in Amsterdam, one of the oldest public parks and best known parks in The Netherlands.

Anti-Microbiota Vaccines Modulate the Tick Microbiome in a Taxon-Specific Manner
bioRxiv, 2021 Anti-tick microbiota vaccines have been shown to impact tick feeding but its specificity has not been demonstrated. In this study we aimed to investigate the impact of immune targeting of keystone microbiota bacteria on tick performance, and tick ...

Harmonizing taxon names in biodiversity data: A review of tools, databases and best practices
Methods in Ecology and Evolution, 2021 The process of standardizing taxon names, taxonomic name harmonization, is necessary to properly merge data indexed by taxon names. The large variety of taxonomic databases and related tools are often not well described.
