Seed storage-mediated dormancy alleviation in Fabaceae from campo rupestre [PDF]

Acta Botanica Brasilica, 2015
ABSTRACTWe studied the effects of seed storage on germination and dormancy alleviation in three species of Fabaceae endemic to campo rupestrein southeastern Brazil. Fresh seeds of Collaea cipoensis, Mimosa maguirei and Mimosa foliolosawere set to germinate and germination of seeds after four, five and 13 years of storage was tested.

Regeneration after fire in campo rupestre: Short- and long-term vegetation dynamics [PDF]

Flora, 2018
The Cerrado (Brazilian savanna) is the second largest biome in Brazil, covering 22% of the country, and campo rupestre is one of the most biodiverse ecosystem. Campo rupestre are extremely old mountaintop tropical ecosystems, composed of a mosaic of herbaceous, shrubland and savanna vegetation, generally located above 900 m above sea level ...

Lack of floristic identity in campos rupestres − a hyperdiverse mosaic of rocky montane savannas in South America [PDF]

, 2017
The rocky montane savannas of South America, known as campos rupestres in Brazil, where they largely occur, represent a megadiverse habitat housing c.15% of the Brazilian vascular flora in less than 1% of the Brazilian territory.

Sauvagesia (Ochnaceae) in the campos rupestres of the Espinhaço Range, Brazil

Rodriguésia, 2023
Abstract The campos rupestres (rupestrian grasslands) of the Brazilian Espinhaço Range are renowned for harboring extraordinary plant diversity and endemism, yet many groups representative of this habitat remain taxonomically understudied. Sauvagesia, a predominantly neotropical genus of Sauvagesieae (Ochnaceae), is a classic example. In this study, we

Taxonomic treatment, geographic distribution and preliminar conservation status of Croton sect. Barhamia subsect. Barhamia (Euphorbiaceae) in Brazil

Nordic Journal of Botany, EarlyView.
The genus Croton (Euphorbiaceae) is an exceptionally megadiverse genus, encompassing roughly 1200 species that are predominantly distributed across tropical regions globally. For the New World, the genus is organized into three subgenera (Adenophylli, Geiseleria and Quadrilobi) and 31 sections, with C. sect. Barhamia standing out with its approximately

Floral trait similarity at the community‐level increases reproductive success suggesting facilitation through pollinator sharing

Oikos, EarlyView.
The ability of plants to attract pollinators is context‐dependent, influenced by floral traits, abundance, and resources from the plant community. Indirect interactions through shared pollinators, from competition to facilitation, may lead to varied reproductive outputs in plants, and the mechanisms behind these interactions remain to be fully ...
