COI Barcoding of the Shorebirds: Rates of Evolution and the Identification of Species

Elbourne, Rebecca 07 December 2011 (has links)
This study assembles COI barcodes from 1814 specimens from the shorebird order, Charadriiformes and examines variation relative to time, rate of evolution and taxonomic level. In the suborder Scolopaci, 95% of sampled species were identified correctly. COI barcode variation within monotypic species was low (0-1% maximum distance) but showed a wide range within polytypic species (0-5%). Preliminary Charadrii results suggest similar trends but success is reduced in the third suborder, Lari. Rates of COI evolution are found to be lowest in the Lari and this leads to reduced species identification in recently radiated families: just 49% of the Laridae and 57% of the Stercoraridae are identified but 100% of the older Alcidae. In the faster Scolopaci, subspecies are at the limit of resolution with some well differentiated subspecies not distinguished by barcodes. The interplay of evolutionary rates, divergence dates and gene flow appears to determine COI barcode differentiation between taxa.

Les classificateurs BU (CL. 14), GA (CL. 16), KU (CL. 17) et MU (CL. 18) dans l'expression de la localisation en kikongo (lari) / Classifiers bu (cl. 14), ga (cl. 16), ku (cl. 17), and mu (cl, 18) in localization in Kikongo (Lari)

Bagamboula, Elise Solange 26 June 2019 (has links)
Les classificateurs ga (cl. 16), ku (cl. 17) et mu (cl. 18) marquent respectivement les valeurs de « contact », de « distance » et d’« intériorité » : a) lorsqu’ils sont préfixés à la base ‑úma /endroit/ ; b) lorsqu’ils apparaissent dans le verbe conjugué ou préfixés aux thèmes des déterminants ; c) lorsqu’ils sont suivis d’un nom en isolation ; d) ou lorsqu’ils ils sont suivis d’un verbe.Bu (cl. 14) marque en outre une valeur « abstraite » lorsqu’il se combine avec des bases lexicales ; il exprime le temps, la comparaison et la cause, lorsqu’il est préfixé aux thèmes des déterminants ; il sert en troisième lieu à marquer l’hypothèse lorsqu’il est employé sous la forme d’un morphème libre. / Classifiers ga (cl. 16), ku (cl. 17) and mu (cl. 18) express respectively “contact”, “distance” and “interiority”: a) when they are prefixed by ‑úma /place/; b) when they appear in conjugated verbs or are prefixed by themes of determinants; c) when they are followed by a name in the form of a free morpheme; d) or when they are followed by a verb. Bu (cl. 14) expresses, in addition, “abstract” value when it is combined to lexical bases; when it is prefixed to the themes of determinants, it carries temporal, comparative and causal values; it serves thirdly to mark the hypothesis in the form of a free morpheme.
