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

open access: yesLand 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.

Leaf Damage and Associated Cues Induce Aggressive Ant Recruitment in a Neotropical Ant-Plant [PDF]

open access: yes, 1998
Induced chemical responses following herbivory are common in plants. Plant responses that change the level of physical or biotic defense are less well documented and poorly understood. Many Azteca spp. ants are obligate inhabitants of Cecropia spp. trees.

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

open access: yesBiological 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.

Effects of Environmental Changes in Degraded Areas on the Establishment of Plant Communities in the Brazilian Cerrado

open access: yesInternational Journal of Forestry Research, Volume 2025, Issue 1, 2025.
Understanding the interrelationships between plant communities and soil attributes in gully erosion can make valuable contributions to strategies focused on the conservation and recovery of degraded areas. Thus, we aimed to evaluate how the composition and structure of different plant communities are affected by soil attributes in a degraded area by ...

In vivo and in vitro toxicological evaluations of aqueous extract from Cecropia pachystachya leaves

open access: yesJournal of Toxicology and Environmental Health, Part A, 2020
leaves are popularly used to treat asthma and diabetes. Despite the widespread consumption of this plant, there are few scientific studies regarding its toxicological potential. In order to conduct a thorough study concerning the potential adverse effects, the aim of this study was to assess acute and subacute toxicity tests of crude aqueous extract ...

Diversity and dominance in bird assemblages across habitats in the Ñeembucú wetlands complex

open access: yesBiotropica, Volume 56, Issue 5, September 2024.
We analyzed how the composition of neotropical bird assemblages vary among habitats (riparian forests, natural grasslands, savannas, and anthropized sites) in the Ñeembucú Wetlands Complex, the largest wetland system in Paraguay. We found a high bird richness (209 species) that contrasted with a pattern of dominance by a small set of 16 species that ...
