Biodiversity on island chains: neutral model simulations [PDF]
, 2010 A neutral ecology model is simulated on an island chain, in which neighbouring islands can exchange individuals but only the first island is able to receive immigrants from a metacommunity. It is found by several measures that biodiversity decreases along the chain, being highest for the first island. Subtle changes in taxon abundance distributions can

Taxon Sampling, Bioinformatics, and Phylogenomics [PDF]
Systematic Biology, 2003 Taxon sampling is often thought to be of extreme importance for phylogenetic inference, and increased sampling of taxa is commonly advocated as a solution to resolving problematic phylogenies. Another solution is to increase the number of sites (by sequencing additional genes) sampled for each taxon.

On the Unnecessary and Misleading Taxon “Cetartiodactyla”
Journal of Mammalian Evolution, 2021 The name “Cetartiodactyla” was proposed in 1997 to reflect the molecular data that suggested that Cetacea is closely related to Artiodactyla. Since then, that taxon has spread in popularity, even outside the scientific literature. However, the implica- tions of the name are confusing, because Cetacea and Artiodactyla are not sister-taxa.

Assessing the value of DNA barcodes for molecular phylogenetics: effect of increased taxon sampling in lepidoptera. [PDF]
PLoS ONE, 2011 BACKGROUND: A common perception is that DNA barcode datamatrices have limited phylogenetic signal due to the small number of characters available per taxon.

Distinguishing Convergence on Phylogenetic Networks [PDF]
arXiv, 2016 We compare the phylogenetic tensors for various trees and networks for two, three and four taxa. If the probability spaces between one tree or network and another are not identical then there will be phylogenetic tensors that could have arisen on one but not the other. We call these two trees or networks distinguishable from each other.

Biodiversity Information Science and Standards, 2019 The Finnish Biodiversity Information Facility, FinBIF (https://species.fi), has developed its own taxon database. This allows FinBIF taxon specialists to maintain their own, expert-validated view of Finnish species. The database covers national needs and can be rapidly expanded by our own development team.

Plant Protection Science, 2015 Taxonomical bias for the intensity of research in natural sciences is well documented but less data exists for crop protection, weed and phytopathology sciences.
