What is a species? A new universal method to measure differentiation and assess the taxonomic rank of allopatric populations, using continuous variables
Abstract Existing models for assigning species, subspecies, or no taxonomic rank to populations which are geographically separated from one another were analyzed. This was done by subjecting over
Diagnosability of mtDNA with Random Forests: Using sequence data to delimit subspecies
TLDR
It is demonstrated that Random Forests produces classification models that perform well for diagnosing subspecies and species and the importance of reporting the certainty with which individuals in the training data are classified in order to communicate the strength of the classification model and diagnosability estimate.
The Structure of the Endophallus Is a New Promising Feature and a Key to Study of Taxonomy of the Subgenus Metallotimarcha of the Genus Timarcha (Coleoptera, Chrysomelidae) in the Caucasus
TLDR
Examination of both external characters and endophallus structure in the specimens from the Caucasus revealed that Caucasian Timarcha hummelii is a separate species, which differs from European members of the subgenus Metallotimarcha by the internal structure of male aedeagus, namely, manubrium of the endphallus.
The Structure of the Endophallus Is a New Promising Feature and a Key to Study of Taxonomy of the Subgenus Metallotimarcha of the Genus Timarcha (Coleoptera, Chrysomelidae) in the Caucasus
TLDR
Examination of both external characters and endophallus structure in the specimens from the Caucasus revealed that Caucasian Timarcha hummelii is a separate species, which differs from European members of the subgenus (T. gibba) by the internal structure of male aedeagus, namely, manubrium of the endphallus.
Morphological variation in the Sabota Lark Calendulauda sabota in southern Africa
TLDR
Biometric data obtained from museum skins in South Africa are used to evaluate morphological variation in the subspecies as a basis for the delineation of Sabota Lark into the thick- billed, slender-billed and intermediate groups.
Morphological differentiation of Icelandic Redpolls, Acanthis flammea islandica
TLDR
The analyses support the grouping of the three Acanthis species, although a large split is observed between the A. hornemanni subspecies and the subspecies status of the Icelandic Redpoll remains unclear.
A review of the subspecies status of the Icelandic Purple Sandpiper Calidris maritima littoralis
TLDR
The results do not provide support for the subspecies status of the Icelandic population because the nominate and Icelandic subspecies fail to uphold Amadon’s rule, and genetic analyses indicate that the study populations derive from a single shared refugium.
Environmental enrichment with simple puzzle feeders increases feeding time in fly river turtles ([I]Carettochelys insculpta[/I])
TLDR
The use of puzzle feeders for enriching captive Fly River turtles (Carettochelys insculpta) in order to prolong feeding activity was outlined, as feeding time was significantly increased by 35 minutes.
Amak Island Song Sparrows (Melospiza melodia amaka) are not evolutionarily significant
TLDR
It is proposed that the isolated, small, and endemic population of Amak Island Song Sparrows is not an evolutionarily significant unit (ESU), not a valid subspecies, not a distinct population segment (DPS), nor a diagnosable conservation unit, but rather a sink colonized by regional source populations.

TLDR
The large series permit an evaluation of the range of variation which is considerable, and of subspecific limits which do not agree with those set by Uttal and Friedmann.
