Alpha-taxonomy in the cricetid rodent Neomicroxus, a first assessment [PDF]

Therya, 2020
Neomicroxus , a recently named genus, comprises small-bodied cricetid rodents patchily distributed in high-Andean ranges from Ecuador to Venezuela. Currently, two species of Neomicroxus are recognized, N. bogotensis , endemic to the Cordillera Oriental in Colombia and Cordillera de Merida and Paramo de Tama in Venezuela, and N.

OPHTHALMOSAURIDS (ICHTHYOSAURIA: THUNNOSAURIA): ALPHA TAXONOMY, CLADES AND NAMES [PDF]

Publicación Electrónica de la Asociación Paleontológica Argentina, 2015
Abstract. Thunnosaurian ichthyosaurs represent the paradigm of reptilian body designed for a pelagic life style. Most derived thunnosaurian, the ophthalmosaurids, have been traditionally considered as members of a declining lineage. New findings and the re-examination of historical collections radically changed our conceptions about them ...

Evaluating Alpha and Beta Taxonomy in Ant-Nest Beetles (Coleoptera, Carabidae, Paussini) [PDF]

Psyche: A Journal of Entomology, 2013
We evaluated completeness, accuracy, and historical trend of the taxonomic knowledge on the myrmecophilous ground beetle tribe Paussini (Coleoptera, Carabidae, Paussinae). Accumulation curves for valid names and synonyms of species, subgenera, and genera were modelled using logistic functions. Analyses of trends in synonymies suggest that few currently

Phylogeography and alpha taxonomy of the common dolphin (Delphinus sp.) [PDF]

Journal of Evolutionary Biology, 2006
Abstract The resolution of taxonomic classifications for delphinid cetaceans has been problematic, especially for species in the genera Delphinus, Tursiops and Stenella. The frequent lack of correspondence between morphological and genetic differentiation in these species raises questions about the mechanisms responsible for their ...

Phylogeography of Loxodontomys micropus with comments on the alpha taxonomy of Loxodontomys (Cricetidae: Sigmodontinae) [PDF]

Journal of Mammalogy, 2010
Loxodontomys micropus is a rodent that is widely distributed in Andean and Patagonian Argentina and Chile. This range covers a heterogeneous area that has been influenced by geologic and palaeoclimatic events, such as the glaciations during the Neogene.

Alpha Taxonomy of the Russian Permian Procolophonoid Reptiles [PDF]

Acta Palaeontologica Polonica, 2009
European Russia has been the source of many procolophonoid taxa from both the Permian and Triassic, and a Permian origin for the procolophonoid family Procolophonidae has been based on the Russian taxon Microphon exiguus. Recently, this taxon was reclassified as a seymouriamorph and, in its place, the taxa Nyctiphruretus, Suchonosaurus, and Kinelia ...

A reappraisal of Neotropical Vanilla. With a note on taxonomic inflation and the importance of alpha taxonomy in biological studies

Lankesteriana, 2020
Despite the long-standing cultural importance and botanical interest in  Vanilla, many taxa belonging to the genus remain poorly understood. Vanilla species generally have broad geographical and ecological distributions. Most species are found in multiple countries, while local endemics are rare.

Alpha taxonomy of the genus Kessleria Nowicki, 1864, revisited in light of DNA-barcoding (Lepidoptera, Yponomeutidae). [PDF]

Zookeys, 2015
The taxonomy of Kessleria, a highly specialized montane genus of Yponomeutidae with larval host restriction to Saxifragaceae and Celastraceae (Saxifraga spp. - subgenus Kessleria; Saxifraga spp. and Parnassia spp. - subgenus Hofmannia), is revised based on external morphology, genitalia and DNA barcodes.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
