We studied the reproductive biology of Cipocereus minensis, an endemic columnar cactus of the Espinhaço Mountain Range, Southeastern Brazil, focusing on floral biology, breeding system, and pollination. We described floral morphology and evaluated the role of nocturnal and diurnal pollinators on the reproductive success in two populations. C. minensis has large, horizontal, cream-colored, chiropterophilous...
Temporal and spatial scales are key factors that affect species distribution. Temporary lakes may be intensely affected by both scales, and the aquatic macrophyte community can rapidly respond to such environmental changes. Here, we investigate 26 Neotropical temporary upland lakes and describe the species richness and composition as well as the species richness within functional groups and the functional...
Dispersal is fundamental to the colonization of oceanic islands that were never connected to larger landmasses. For species with limited dispersal capabilities, colonization of remote islands can be followed by isolation and speciation. The tidepool fish community of Trindade Island, 1,160 km off the Brazilian coast at the eastern end of the Vitória-Trindade Chain, is composed of 18 species from 11...
Machaerium sect. Lineata, with around 30 species of trees, shrubs and lianas, occurs from southern Mexico to northern Argentina and is characterized by the presence of spinescent stipules and leaflets with cladodromous venation. The difficulty of distinguishing species in this section is compounded by a proliferation of taxonomic names. The taxonomy, morphology, and geographic distribution of Machaerium hirtum...
