Weak Genetic Isolation and Putative Phenotypic Selection in the Wild Carnation (Caryophyllaceae).

By relating genetic divergence at neutral loci, phenotypic variation, and geographic and environmental distances, it is possible to dissect micro-evolutionary scenarios involving natural selection and neutral evolution. In this work, we tested the patterns of intraspecific genetic and phenotypic variation along an elevational gradient, using as study system. We genotyped genome-wide SNPs through ddRAD sequencing and quantified phenotypic variation through multivariate morphological variation.

Digitization of the historical Herbarium of Michele Guadagno at Pisa (PI-GUAD).

The herbarium digitization process is an essential first step in transforming the vast amount of data associated with a physical specimen into flexible digital data formats. In this framework, the Herbarium of the University of Pisa (international code PI), at the end of 2018 started a process of digitization focusing on one of its most relevant collections: the Herbarium of Michele Guadagno (1878-1930). This scholar studied flora and vegetation of different areas of southern Italy, building a large herbarium including specimens collected by himself, plus many specimens obtained through exchanges with Italian and foreign botanists.

A Morphometric Analysis of the Complex (Asteraceae).

The genus (Asteraceae, Anthemideae) includes 26 species of aromatic evergreen shrubs endemic to the western Mediterranean Basin. is widely used as ornamental plant, in xerigardening, and in ethnobotany. The complex, including about half of the known species diversity, has been properly investigated on systematic and taxonomic grounds only recently, and a complete morphometric study is still missing.

Integrative Taxonomy of (Plumbaginaceae), with a Special Focus on the Putative Subspecies Endemic to the Apennines.

Three subspecies of are reported from Italy, two of which are considered endemic to the Apennines. The taxonomic value of these two taxa ( subsp. and subsp.

An Integrated Taxonomic Approach Points towards a Single-Species Hypothesis for (Asteraceae) in Corsica and Sardinia.

is a plant genus of dwarf aromatic shrubs that includes about 26 species native to the western Mediterranean Basin. In Corsica and Sardinia, two of the main islands of the Mediterranean, (tetraploid) and (hexaploid) are reported. Along with the cultivated pentaploid , these species form a group of taxa that is hard to distinguish only by morphology.

Typification of 14 names in the group (Caryophyllaceae).

The nomenclature of 14 taxa from Central and Southern Europe within the group is discussed. Jord., Jord.
