Turkish Salix species: Molecular phylogeny and morphology

Acar, Pelin
Kaya, Zeki
This study provides a new insight into Turkish Solix L. systematics, using a molecular phylogeny and numerical morphotnetric analysis approach. Despite its economic importance for bioenergy, there is to date no record of any extensive study on this Turkish willow species. twenty-four Solix species and one hybrid were subjected to molecular and morphometric evaluation, in which one gene region of the external transcribed spacer (ETS) of the 18S-26S nuclear ribosomal DNA and 11 morphologic-al characters were analyzed using a Bayesian Analysis of Beast program and Multiple Correspondence Analysis (MCA) in R. The results indicate that Salix species in -Turkey could be accurately classified at the subgenera level, considering the selected gene region and morphological traits (subgenus Sex and Vetrix). Life form, leaf shape (Dim 1) and bud scale (Dim 3) were highly discriminative at the subgenera level. The molecular and morphological data confirmed that the taxonomic position of Sailx ornplexica Os needs to be changed as subgenus Sallx. Additionally, the members of subgenus Softy, S. acmophylia and S. pentandroides were all clustered distantly from other species of the subgenus.


Numerical taxonomy of the Genus Salvia (Sage) in East and Southeast Anatolia
Kahraman, Ahmet; Doğan, Musa; Arı, Nurettin (2017-12-08)
This study aims to carry out multivariate statistical analyseson 59 taxa of the genus SalviaL. (sage) naturally found in East and Southeast Anatolia in Turkey based on macromorphological, anatomical, palynological and mericarp micromorphological characteristics, to construct an infrageneric grouping in the genus and tounderstandthephylogeneticrelationships between taxa.For the multivariate correspondence analyses, OTUs (Operational Taxonomic Units) representing different populations of the Salvi...

Ölçek, COVID-19 pandemi sürecine ilişkin 23 stresör maddesinden ve enfekte olma, aktiviteler ve kaynaklarla ilişkili stres alanları olmak üzere üç alt fa...
Turkish adaptation of the trait meta-mood scale
Aksoz, Idil; Bugay, Asli; Erdur Baker, Özgür (2010-02-08)
This study investigates the reliability and validity of the Turkish version of the Trait Meta-Mood Scale (Salovey, Mayer, Goldman, Turvey & Palfai, 1995). This scale was originally developed to measure the ability to understand one's mood, to find the degree to which individuals moderate their moods, and to find correspondences between feelings and thoughts. The Trait Meta-Mood Scale (TMMS) and Ruminative Response Scale (RRS) were applied to 319 university students. Confirmatory and exploratory factor analy...
Turkish version of the survey of attitudes toward statistics: Factorial structure invariance by gender
Sarikaya, Esma Emmioglu; Ok, Ahmet; Çapa Aydın, Yeşim; SCHAU, Candace (2018-04-01)
This study examines factorial structure and the gender invariance of the Turkish version of the Survey of Attitudes toward Statistics (SATS-36). The SATS-36 has 36 items measuring six components: affect, cognitive competence, value, difficulty, effort, and interest. Data were collected from 347 university students. Results showed that the Turkish version of the SATS-36 had a six-factor structure and it was gender invariant. Internal consistency coefficients supported good score reliability for the subscales...
