Plant-feeding beetle species are diverse and often individually highly variable. Accurate
classifications can be difficult to establish yet are essential for study of evolutionary patterns …

Abstract Background and Aims Herbaria are the most important source of information for
plant taxonomic work. Resources and technologies available today, such as digitized …

Delimiting species boundaries is a major goal in evolutionary biology. An increasing volume
of literature has focused on the challenges of investigating cryptic diversity within complex …

Background In this study, we investigate species limits in the cyanobacterial lichen genus
Rostania (Collemataceae, Peltigerales, Lecanoromycetes). Four molecular markers (mtSSU …

The sweet tabaiba (Euphorbia balsamifera Ait.) is one of the classical examples of the
disjunct biogeographic pattern known as Rand Flora. This species is currently circumscribed …

Most studies investigating the genomic nature of species differences anticipate
monophyletic species with genome-wide differentiation. However, this may not be the case …

Pollen morphology has been a fundamental tool in the study of evolution and phylogeny in
angiosperms. As sister to Asteraceae, Calyceraceae provides critical insights into …

Calyceraceae comprises 46 species mostly endemic to the Andes and Patagonia in
Southern South America, and it is the sister family of Asteraceae, one of the largest …

 Abstract An accurate taxa delimitation, based on a full understanding of evolutionary
processes involved in taxa differentiation, can be gained from a combination of ecological …

Calyceraceae is a small South American family sister to Asteraceae. Previous phylogenetic
analyses revealed that Calyceraceae genera are para‐or polyphyletic. Fruit and …
