New records of angiosperms for the state of Roraima, Brazil
Rodrigues, Rodrigo Schütz; Oliveira Perdiz, Ricardo de; Flores, Andréia SilvaKnowledge of the flora of the Brazilian Amazon is very incomplete and many areas are still botanically unexplored. This work reports new records of angiosperms to Roraima from two conservation units in the southwest of the state, the Serra da Mocidade National Park and Niquiá Ecological Station. New records for four genera and 23 species belonging to 15 angiosperm families were found. Leguminosae had the highes...
Volatile monoterpene ‘fingerprints’ of resinous Protium tree species in the Ama...
Piva, Luani Rde Oliveira; Jardine, Kolby J.; Gimenez, Bruno Oliva; Oliveira Perdiz, Ricardo de; Menezes, Valdiek S.; Durgante, Flávia MachadoVolatile terpenoid resins represent a diverse group of plant defense chemicals involved in defense against herbivory, abiotic stress, and communication. However, their composition in tropical forests remains poorly characterized. As a part of tree identification, the ‘smell’ of damaged trunks is widely used, but is highly subjective. Here, we analyzed trunk volatile monoterpene emissions from 15 species of the ...
Decomposition rates of coarse woody debris in undisturbed Amazonian seasonally ...
Barbosa, Reinaldo Imbrozio; Castilho, Carolina Volkmer de; Oliveira Perdiz, Ricardo de; Damasco, Gabriel; Rodrigues, Rafael; Fearnside, Philip MartinEstimates of carbon-stock changes in forest ecosystems require information on dead wood decomposition rates. In the Amazon, the lack of data is dramatic due to the small number of studies and the large range of forest types. The aim of this study was to estimate the decomposition rate of coarse woody debris (CWD) in two oligotrophic undisturbed forest formations of the northern Brazilian Amazon: seasonally floo...
