Taxonomic and phylogenetic analyses of great apes and humans have identified two potential areas of conflict between molecular and morphological data: phylogenetic relationships among living species and differentiation of great ape subspecies. Here we address these problems by using morphometric data. Three-dimensional landmark data from the hominoid temporal bone effectively quantify the shape...

Two new species of Cladosporium found on necrotic needles of Pinus ponderosa trees in Patagonia, Argentina, are described as C. chubutense and C. pini-ponderosae. An additional isolate from dead leaves of Cortaderia collected in Colombia, which is a sister taxon to the species occurring on Pinus, is described as Cladosporium colombiae. These species are phylogenetically closely related, but dif...

The Hibiscus genus is a member of the Malvaceae family with striking flowers various colors. that easy to find in Indonesia because it usually used as an ornamental plant, hedge cut flower, medicinal or tea for drinking. This research was conducted know phenetic relationship 6 species based on morphological characters. by observing 57 characteristics Hibiscus, then UPGMA (Unweighted Pair Group ...

DOWNIE, S. R., and MCNEILL, J. 1990. A note on the taxonomic status of Euphrasia randii (Scrophulariaceae). Can. J. Bot. 68: 1531-1535. A reexamination of the phenetic relationships among the previously recognized infraspecific taxa of Euphrasia randii using principal component analyses and four clustering methods indicates that the recognition of these infraspecific taxa is unwarranted. This c...

Nicotiana is found predominantly in the Americas and Australia, but also has representatives Africa Pacific Islands. All native Australian species belong to section Suaveolentes. The number of this uncertain subject revision. An example uncertainty taxonomic status a South accession colloquially termed ‘Corunna’. Here, we report sequences for nuclear plastid markers N. sp. Corunna (D.E.Symon 17...

Inference involving diversity gradients typically is gathered by mechanistic tests involving single dimensions of biodiversity such as species richness. Nonetheless, because traits such as geographic range size, trophic status or phenotypic characteristics are tied to a particular species, mechanistic effects driving broad diversity patterns should manifest across numerous dimensions of biodive...
