Sampling Errors in Phylogeny I
The sampling variance of nucleotide diversity or branch length in a phylogenetic tree constructed by any distance method provides a criterion to judge whether a deduction or an inference made from data is statistically significant. However, computation of the sampling variance is usually tedious, particularly when the number of operational taxonomic units (OTUs) or DNA sequences is large, and m...
متن کاملPhylogeny and karyotype evolution of the Iberian Leptynia attenuata species complex (Insecta Phasmatodea).
An in-depth analysis of the Leptynia attenuata species complex has been performed by cytochrome oxidase subunit 2 (cox2) gene sequencing as well as karyotype and allozyme analysis. The whole set of data allows to largely resolve the taxonomy of the group and suggests an overall trend of chromosomal repatternings through a progressive reduction of the chromosome number. A previously suggested ne...
متن کاملVariations on a theme: Karyotype comparison in Eurasian Myotis species and implications for phylogeny
The phylogenetic relationships within the large genus Myotis are still unsolved to a high degree although several morphological and molecular studies have been undertaken recently. In cytogenetic respect, Myotis is a very homogeneous genus as nearly all species show a karyotype with 44 chromosomes. Application of banding techniques in 17 Eurasian Myotis taxa revealed complete conservation of ch...
متن کاملChromosomal phylogeny and karyotype evolution in x=7 crucifer species (Brassicaceae).
Karyotype evolution in species with identical chromosome number but belonging to distinct phylogenetic clades is a long-standing question of plant biology, intractable by conventional cytogenetic techniques. Here, we apply comparative chromosome painting (CCP) to reconstruct karyotype evolution in eight species with x=7 (2n=14, 28) chromosomes from six Brassicaceae tribes. CCP data allowed us t...
متن کاملMolecular Phylogeny, Laboratory Rearing, and Karyotype of the Bombycid Moth, Trilocha varians
This study describes the molecular phylogeny, laboratory rearing, and karyotype of a bombycid moth, Trilocha varians (F. Walker) (Lepidoptera: Bombycidae), which feeds on leaves of Ficus spp. (Rosales: Moraceae). The larvae of this species were collected in Taipei city, Taiwan, and the Ryukyu Archipelago (Ishigaki and Okinawa Islands, Japan). Molecular phylogenetic analyses revealed that T. var...
