Pollen Morphology of Selected Endemic Eudicots From the FLORAS Botanical Garden, Southern Bahia, Brazil. [PDF]

Microsc Res Tech
This study describes the pollen morphology of twelve endemic species from the Atlantic Forest, revealing subtle morphopollinic variations. Diagnostic characters such as pollen shape, exine ornamentation, and amb type highlight the region's floristic diversity, providing valuable insights into the ecological and conservation significance of Brazil's ...

"Touch&Play" Wood Typification by the MasSpec Pen. [PDF]

J Mass Spectrom
ABSTRACT We have investigated the ability of a MasSpec Pen (MSPen) “three‐in‐one” (extraction, transfer, and ionization) device coupled to a mass spectrometer to provide instantaneous chemical profiles that could promptly characterize wood samples from the mahogany (Meliaceae) family.

Combining phylogenomic and morphological data reveals new patterns of diversity in the national tree of Brasil, Paubrasilia echinata

, 2022
Abstract Paubrasilia echinata (Lam.) Gagnon, H. C. Lima & G. P. Lewis (“Pau Brasil”) is the national tree of Brazil and an endangered species endemic to the Brazilian Atlantic Forest. The extensive range of distribution, spanning over 2000 km distance, is matched by extensive plasticity in leaf morphology.

Lower oxidative damage and cell wall loosening, mediated or not by auxin, as part of the tolerance mechanism of Paubrasilia echinata morphotypes in the shade and full sun [PDF]

Acta Botanica Brasilica, 2021
ABSTRACT Paubrasilia echinata presents three morphotypes that differ from each other in leaf morphology (small morphotype-SM, medium morphotype-MM, and large morphotype-LM) with indications of divergence between them regarding irradiance tolerance. The present study aimed to identify possible physiological and growth patterns in P. echinata morphotypes

Evolutionary patterns in the geographic range size of Atlantic Forest plants

Ecography, Volume 43, Issue 10, Page 1510-1520, October 2020., 2020
Species’ geographic range size is arguably the single most important predictor of vulnerability to extinction and a key metric in ecology. Despite this, patterns of specific variation in range size and their underlying reasons are still poorly understood.

ECOPHYSIOLOGICAL RESPONSES OF MEDIUM MORPHOTYPE OF Paubrasilia echinata (Lam.)Gagnon,H.C.Lima and G.P.Lewis RAISED UNDER FULL SUNLIGHT AND NATURAL SHADE [PDF]

Revista Árvore, 2019
ABSTRACT The existing inconsistent data on the irradiance needs of Brazilwood plants Paubrasilia echinata (Lam.) Gagnon,H.C.Lima and G.P.Lewis. can be explained by their phenotypical variations. While small-leaf morphotypes grows better in the shade, not tolerating environments with high irradiance, a recently discovered population of medium morphotype
