Abstract Given a set R of rooted phylogenetic trees on overlapping taxa, it takes polynomial time to decide whether or not there exists a rooted phylogenetic tree that is compatible with R . Since not all evolutionary histories for a set of species can be explained by a single tree, it is...
A phylogenetic analysis of the grass family (Poaceae) was conducted using two character sets, one representing variation in 364 mapped and cladistically in
Much recent progress in evolutionary biology is based on the inference of ancestral states and past transformations in important traits on phylogenetic trees. These exercises often assume that the tree is known without error and that ancestral states and character change can be mapped onto it exactly...

A combinatorial optimization problem regarding assignments of real numbers (called reconstructions) on a tree has been discussed in phylogenetic analysis. Recently, a clear method for finding most-parsimonious reconstructions (MPRs) on a given end-labeled-tree (phylogenetic tree) has been presented by...
phylogenetic relationshipstinging hairUrticeaeThis study examines phylogenetic relationships among the 12 genera of Urticeae (Urticaceae) and investigates the pattern of morphological evolution based on analysis of nuclear ribosomal internal transcribed spacer (nrITS) and two plastid DNA regions (rbcL exon...
Molecular analyses of the last decades helped solving the major open questions on the external and internal phylogenetic relationships of primates. The present review uses these data for the inferencedoi:10.1007/s13127-016-0279-1HerlynHolger
1.3 Optimization of ancestral distributions The estimation of ancestral distributions was performed using the same phylogenetic trees as for character ancestral state reconstructions. Three meth- ods, the parsimony-based dispersal-vicariance method (DIVA) (Ronquist, 1997), the ML-based methods of Ree ...
The recent introduction of methodologies for including continuous data directly in a phylogenetic analysis has increased the number of available characters, making it possible to produce phylogenies based, in whole or part, on continuous character data collected from such taxa. Geometric morphometric ...
Molecular phylogenetic analysis and character evolution in Pseudostellaria (Caryophyllaceae) and description of a new genus, Hartmaniella, in North America. Based on sequences of ITS, matK, rbcL and rps16, a phylogenetic tree is constructed for Pseudostellaria and outgroup genera of Caryophyllaceae su...
