Angiosperm disjunction "Campos rupestres - restingas": a re-evaluation Disjunção de Angiospermas Campos Rupestres - Restingas: uma reavaliação

Acta Botânica Brasílica, 2007
A disjunct distribution pattern between the extrazonal formations of the campos rupestres (rocky grasslands) in the Espinhaço mountain range and the restingas (coastal strand vegetation) in Brazil has been proposed repeatedly for several flowering-plant ...

Evidence of nitric acid uptake in warm cirrus anvil clouds during the NASA TC4 campaign [PDF]

, 2010
Uptake of HNO3 onto cirrus ice may play an important role in tropospheric NOx cycling. Discrepancies between modeled and in situ measurements of gas-phase HNO3 in the troposphere suggest that redistribution and removal mechanisms by cirrus ice have been ...

EFFECT OF TOPSOIL STOCKPILING ON THE VIABILITY OF SEED BANK IN FIELD PHYTOPHYSIOGNOMIES CAMPOS DE ALTITUDE [PDF]

CERNE, 2017
ABSTRACT The viability of propagules during topsoil stockpiling is a limiting factor in ecological restoration projects and little is known about the species distributed in the campos de altitude. This work was carried out to investigate the viability of propagules present in the topsoil under campos de altitude vegetation, stockpiled for up to 12 ...
