Growth‐form and taxonomy in Arenaria sect. Plinthine (Caryophyllaceae)

Phylogenetic and phylogeographic analysis of the western Mediterranean Arenaria section Plinthine (Caryophyllaceae) based on nuclear, plastid, and morphological markers

The use of molecular markers, particularly sequence data, in phylogeny reconstruction of plant groups above the genus level has proven successful in the last decade (Soltis & al., 1998, 2000). Expectedly, as we move down in the systematic hierarchy towards micro-evolutionary levels, conclusive and resolved phylogenies become rare. This is due to several interconnected reasons. Scarcity of marke...

Arenaria Lanuginosa ( Caryophyllaceae ) , Taxonomic Status and Distribution

The geographic and morphological parameters of the widespread Arenaria lanuginosa are explored with the conclusion that in North America the species consists of two, largely allopatric, intergrading varieties: A. l. var. saxosa of the southwestern USA and northwestern Mexico, and A. l. var. lanuginosa of southern Mexico and Central America, extending into South America, where it is widespread, ...

Systematics in Sileneae (Caryophyllaceae) – Taxonomy and Phylogenetic patterns

Pollen discounting and the evolution of selfing in Arenaria uniflora (caryophyllaceae).

Although most models of mating system evolution assign a central role to the male transmission advantage of selfing genotypes, empirical data on the male fitness consequences of increased self-pollination are still uncommon. Here, I use measures of pollen import and export by focal plants in genotyped arrays to investigate the effects of floral morphology and pollination environment on self and...

Correction: Marginal Likelihood Estimate Comparisons to Obtain Optimal Species Delimitations in Silene sect. Cryptoneurae (Caryophyllaceae)

Coalescent-based inference of phylogenetic relationships among species takes into account gene tree incongruence due to incomplete lineage sorting, but for such methods to make sense species have to be correctly delimited. Because alternative assignments of individuals to species result in different parametric models, model selection methods can be applied to optimise model of species classific...
