I have studied nucleotide polymorphism and linkage disequilibrium using multilocus data from 77 fragments, with an average length of fragments of 550 bp, in the deciduous tree Populus tremula (Salicaceae). The frequency spectrum across loci showed a modest excess of mutations segregating at low frequency and a marked excess of high-frequency derived mutations at silent sites, relative to neutra...

Populus (Salicaceae) is one of the most economically and ecologically important genera of forest trees. The complex reticulate evolution and lack of highly variable orthologous single-copy DNA markers have posed difficulties in resolving the phylogeny of this genus. Based on a large data set of nuclear and plastid DNA sequences, we reconstructed robust phylogeny of Populus using parsimony, maxi...

Building on centuries of research based herbarium specimens gathered through time and around the world, much analysis collections data in is being done. In this study, it was analyzed sheets from family Salicaceae. According to records examined, Salicaceae represented by two genera Turkish herbariums. A collection 917 for genus Salix 242 Populus considered six biggest herbaria Türkiye as ANK, I...

Salix L. is the largest genus in the family Salicaceae (450 species). Several classifications have been published, but taxonomic subdivision has been under continuous revision. Our goal is to establish the phylogenetic structure of the genus using molecular data on all American willows, using three DNA markers. This complete phylogeny of American willows allows us to propose a biogeographic fra...

Many clonal plants consist of many connected individual ramets, allowing them to share water and nutrients via physiological integration. Integration among ramets may also improve the ability of clonal plants to tolerate abiotic stress or improve the competitive ability of individual ramets. Here I use a field experiment to determine whether clonal integration improves ramet performance for a w...

Abstract Salicaceae (Malpighiales) has a pantropical distribution, with 58 genera and ca. 1,200 species, the Neotropical region is its center of diversity. In Brazil, 20 104 species can be found, which 35 are endemic. Holding almost half diversity Atlantic Forest domain, Espírito Santo state registered 23 four genera. Facing large number unidentified vouchers from north challenging diagnostic c...
