Morphophysiological Behavior and Cambial Activity in Seedlings of Two Amazonian Tree Species under Shade

Journal of Botany, Volume 2015, Issue 1, 2015., 2015
Variations in light intensity can lead to important anatomical and morphophysiological changes in plants. Aiming to increase knowledge about the Amazonian tree species, this study examines the influence of shade on the cambial activity and development of Parkia gigantocarpa Ducke and Schizolobium parahyba var.

A review of the prevalence, utility, and caveats of using chloroplast simple sequence repeats for studies of plant biology

Applications in Plant Sciences, Volume 2, Issue 12, December 2014., 2014
Microsatellites occur in all plant genomes and provide useful markers for studies of genetic diversity and structure. Chloroplast microsatellites (cpSSRs) are frequently targeted because they are more easily isolated than nuclear microsatellites. Here, we quantified the frequency and uses of cpSSRs based on a literature review of over 400 studies ...

Using Random Amplified Polymorphic DNA to Assess Genetic Diversity and Structure of Natural Calophyllum brasiliense (Clusiaceae) Populations in Riparian Forests

International Journal of Forestry Research, Volume 2014, Issue 1, 2014., 2014
The objective of this study was to assess the genetic variability in two natural populations of Calophyllum brasiliense located along two different rivers in the state of Minas Gerais, Brazil, using RAPD molecular markers. Eighty‐two polymorphic fragments were amplified using 27 primers.

Vegetative responses to temperature and photoperiod in saplings of brazilwood (Caesalpinia echinata Lam., Leguminosae) [PDF]

Brazilian Journal of Plant Physiology, 2006
Caesalpinia echinata Lam. (brazilwood) is an endangered tree species occurring along the eastern coast of Brazil from latitudes 5°56´S to 22°56´S. With such a range of distribution it is expected that temperature and daylength may affect plant development, which was examined in this study.

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

Brazilian 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

Psyche: 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
