Morphological and physiological adjustments of Brazilwood (Caesalpinia echinata Lam.) to direct solar radiation [PDF]

open access: yesBrazilian Journal of Plant Physiology, 2012
This study aimed to characterize the alarm and resistance phases of stress of Caesalpinia echinata under intense irradiance in order to better define its position on forest succession. The alarm phase was identified by rapid reduction in the maximum quantum yield of PSII primary photochemical reactions (ΦP0 = FV/FM) and Performance Index (PIABS ...

Ants as Indicators in Brazil: A Review with Suggestions to Improve the Use of Ants in Environmental Monitoring Programs

open access: yesPsyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
We describe the use of ants as indicators in Brazil, based on a critical review of published articles. The analysis of fifty‐eight papers, encompassing a range of almost 25 years, indicates an increased number of studies using ants as indicators in the last decade. Among the parameters analyzed in the papers, species composition is the most suitable to

Genetic similarity among Caesalpinia echinata trees and their ex situ conservation

open access: yesInternational Journal of Biodiversity and Conservation, 2013
Brazilwood (Caesalpinia echinata Lam) is a tree native to the Atlantic rainforest. It has been exploited since the Brazilian colonial period and the remaining natural populations of C. echinata have been reduced to small forest fragments, or are conserved in arboreta and ecological parks.

Glycosaminoglycans Modify Elastase Action In Vitro and Enhance Elastase‐Induced Cell Death in Cultured Fibroblasts

open access: yesInternational Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
Human neutrophil elastase (HNE) has been shown to be involved on death of different cell types, including epithelial lung cells, which is related to several pulmonary diseases. Since HNE activity may be influenced by extracellular matrix (ECM) molecules such as glycosaminoglycans (GAGs), and fibroblasts are the most common ECM‐producing cells of lung ...
