The generation of plant diversity involves complex interactions between geography, environment and organismal traits. Many macroevolutionary processes and emergent patterns have been identified in different plant groups through the study of spatial data, but rarely in the context of a large radiation of tropical herbaceous angiosperms. A powerful system for testing interrelated biogeographical ...
PREMISE Bromeliaceae form a large, ecologically diverse family of angiosperms native to the New World. We use a bromeliad phylogeny based on eight plastid regions to analyze relationships within the family, test a new, eight-subfamily classification, infer the chronology of bromeliad evolution and invasion of different regions, and provide the basis for future analyses of trait evolution and ra...
A new genus, Cavichiana, is described for a new species of Cicadellini, C. bromelicola, from Southeastern Brazil (states of Rio de Janeiro and São Paulo). The new genus can be distinguished from other genera of the Cicadellini by the following combination of features: (1) head deltoid, strongly produced anteriorly; (2) ocelli located distinctly anterad of anterior eye angles; (3) aedeagus tubul...
Abstract Vascular epiphytes represent almost 10% of all terrestrial plant diversity. Despite the extensive research on functional ecology and challenges epiphytic growth, there is still very little known how exposure to mechanically induced stress affects growth development epiphytes. Therefore, this study investigated effect such mechanical biomass allocation bromeliads. Juvenile plants two sp...
Abstract A new species of Ipomoea, thus far endemic to Caatinga domain, is described. The occurs in a “carrasco” physiognomy - shrubby vegetation on sandy soils characterized by the presence cacti and bromeliads. can be recognized combination morphological characters, including leaf blade with lanate abaxial surface long hairs, sepals lanceolate, acuminate, tomentose, smooth. complete descripti...
