Proteinase inhibitors in Brazilian leguminosae

Memorias do Instituto Oswaldo Cruz, 1991
Serine proteinase inhitors, in the seeds of several Leguminosae from the Pantanal region (West Brazil), were studied using bovine trypsin, a digestive enzyme, Factor XIIa and human plasma Kallikrein, two blood clotting factors.

Home Range, Diet, and Activity Patterns of Common Marmosets (Callithrix jacchus) in Very Small and Isolated Fragments of the Atlantic Forest of Northeastern Brazil

International Journal of Ecology, Volume 2015, Issue 1, 2015., 2015
We evaluate the impact of very small and isolated forest fragments on the common marmosets home range, diet, and activity patterns, in the northeastern Atlantic Forest of Brazil. Three groups were studied in three forest fragments, from January to October 2010, totaling 360 hours of observations and 1,080 field‐hours.

Forest Responses to Fire Regime in the Humid Chaco of Paraguay

Applied Vegetation Science, Volume 29, Issue 3, July/September 2026.
Fire regimes are increasingly shaping vegetation dynamics in the Humid Chaco of Paraguay, a poorly studied fire‐prone region. Our findings highlight resprouting as a key functional trait associated with fire disturbance. Although vegetation structure varied little among regimes, preserving forest patches may help maintain landscape heterogeneity and ...

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.

Hydrogel improves the initial growth and quality of Enterolobium contortisiliquum seedlings

Scientific Electronic Archives, 2019
In restoration in arid and semi-arid zones, the use of strategies to overcome water stress is fundamental to ensure the survival and establishment of seedlings.  The objective of this research is to evaluate the effect of hydrogel, associated to different irrigation frequencies, on initial growth, dry biomass allocation and seedling quality of E ...

Antibacterial, Antioxidant, and Anticholinesterase Activities of Plant Seed Extracts from Brazilian Semiarid Region

BioMed Research International, Volume 2013, Issue 1, 2013., 2013
The antimicrobial, antioxidant, and anticholinesterase activities of ethanolic seed extracts of twenty‐one plant species from Brazilian semiarid region were investigated. The extracts were tested for antimicrobial activity against six bacteria strains and three yeasts.

Experimental poisoning by enterolobium contortisiliquum in sheep.

, 2022
Ingestion of Enterolobium contortisiliquum pods causes digestive disturbances, secondary hepatogenous photosensitization and abortions in ruminants. Pods were administered to sheep via a ruminal cannula to characterize acute poisoning. In Experiment 1, a
