Competition asymmetry with taxon divergence [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2003
Most organisms experience competition for resources, probably most of the time. As the structure and requirements of closely related species are generally liable to be more similar than in distantly linked species, Darwin suggested that the potential for competition was greater in the former.

Giant taxon‐character matrices: the future of morphological systematics

open access: yesCladistics, 2018
Simões et al. ( ) argued that large matrices are linked to the construction of “problematic” characters, and that those characters negatively affect tree topology. In their re‐evaluation of two squamate datasets, however, Simões et al.

AInsectID Version 1.1: An Insect Species Identification Software Based on the Transfer Learning of Deep Convolutional Neural Networks

open access: yesAdvanced Intelligent Discovery, EarlyView.
This paper describes the basis for AInsectID Version 1, a GUI‐operable open‐source insect species identification, color processing, and image analysis software. This paper discusses our methods of algorithmic development, coupled to rigorous machine training used to enable high levels of validation accuracy.

Intraspecific classification of durum wheat: new botanical varieties and forms

open access: yesВавиловский журнал генетики и селекции, 2017
The Wheat Genetic Resources Department of VIR treats Triticum durum Desf. as a separate species. It contains 2 subspecies: subsp. durum and subsp. horanicum. Subsp. horanicum Vav. shows the highest spike density. Subsp.

An Arrow-type result for inferring a species tree from gene trees [PDF]

open access: yesarXiv, 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

KinFin: Software for Taxon-Aware Analysis of Clustered Protein Sequences

open access: yesG3: Genes, Genomes, Genetics, 2017
The field of comparative genomics is concerned with the study of similarities and differences between the information encoded in the genomes of organisms.

Investigating Social Immunity in Swarming Locusts via a Triple Animal–Robot–Pathogen Hybrid Interaction

open access: yesAdvanced Intelligent Systems, EarlyView.
This study explores social immunity in gregarious locusts using a groundbreaking animal–robot–pathogen interaction model. By comparing locust responses to biomimetic agents mimicking healthy and infected individuals, significant behavioral changes are revealed.

The standard lateral gene transfer model is statistically consistent for pectinate four-taxon trees [PDF]

open access: yesarXiv, 2013
Evolutionary events such as incomplete lineage sorting and lateral gene transfer constitute major problems for inferring species trees from gene trees, as they can sometimes lead to gene trees which conflict with the underlying species tree. One particularly simple and efficient way to infer species trees from gene trees under such conditions is to ...

An environmental bacterial taxon with a large and distinct metabolic repertoire

open access: yesNature, 2014
Cultivated bacteria such as actinomycetes are a highly useful source of biomedically important natural products. However, such ‘talented’ producers represent only a minute fraction of the entire, mostly uncultivated, prokaryotic diversity. The uncultured
