The cultivation of the castor bean and the amba’y in Guarani communities of the Argentine Northeast, ethnobotanical approach of their history and cosmology

Bonplandia, 2018
This work studied the historical evidence of the cultivation of “amba’y”, Cecropia pachystachya (Urticaceae) in domestic areas of Guarani communities and its replacement by the castor bean or “ricino”, Ricinus communis (Euphorbiaceae), whose cultivation ...

Aboveground biomass accumulation in Brazilian semi‐deciduous seasonal Atlantic Forest restoration sites over a 20‐year time series

Restoration Ecology, Volume 33, Issue 8, November 2025.
The role of forests undergoing restoration in mitigating climate change is widely accepted. However, periodic assessment of aboveground biomass (AGB) accumulation in actively restored areas is scarce, particularly in tropical forests. Here, we estimated AGB as an indicator of carbon stocks in six Atlantic Forest native species reforestations aged 4–20 ...

Advances in the Preclinical Study of Some Flavonoids as Potential Antidepressant Agents

Scientifica, Volume 2018, Issue 1, 2018., 2018
Flavonoids are phenolic compounds found commonly in plants that protect them against the negative effects of environmental insults. These secondary metabolites have been widely studied in preclinical research because of their biological effects, particularly as antioxidant agents.

Sixty Years of Sugarcane Monoculture Alters Carbon Preservation in Large Soil Macroaggregates in Tropical Soil

Land Degradation &Development, Volume 36, Issue 12, Page 4056-4067, 30 July 2025.
ABSTRACT Frequent and intensive tillage in conventional agriculture disrupts soil aggregates, engendering significant depletion of soil organic carbon (SOC) stocks. Long‐term studies are essential for assessing the impact of sustainable practices on aggregate dynamics and carbon sequestration in sugarcane monocropping in tropical ecosystems.

Yerba Mate (Ilex paraguariensis) Beverage: Nutraceutical Ingredient or Conveyor for the Intake of Medicinal Plants? Evidence from Paraguayan Folk Medicine

Evidence-Based Complementary and Alternative Medicine, Volume 2018, Issue 1, 2018., 2018
The use of medicinal plants mixed with yerba mate (Ilex paraguariensis) has been poorly studied in the ethnopharmacological literature so far. The Paraguayan Mestizo people have the longest tradition of using the yerba mate beverage, apart from the indigenous Guarani people.

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.

Impact of land conservation status on soil functionality in degraded versus old‐growth forest in the Brazilian Atlantic Forest biome

Biological Diversity, Volume 2, Issue 1, Page 14-27, March 2025.
Preserved forests of Ocotea porosa exhibited improved soil functionality with higher levels of soil organic matter (6.56%), exchangeable cations (e.g., Ca2+ at 3.87 cmolc kg−1), and enhanced physical properties, such as soil aggregation, than degraded forests in the Atlantic Forest biome.
