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.

Vertical stratification and effect of petiole and dry leaf size on arthropod feeding guilds in Cecropia pachystachya(Urticaceae) [PDF]

Brazilian Journal of Biology, 2015
AbstractThis study aimed to test for vertical stratification and the effects of dry leaf size on herbivore and predator arthropods and petiole length on insect borers in Cecropia pachystachya. The leaves were sampled in three strata: attached to the plant, suspended on the vegetation and on the ground.

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.

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

International 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 ...

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

Biotropica, 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 ...

Seeding the Pantanal: orchestrating research to overcome restoration barriers in the world's largest tropical wetland

Restoration Ecology, Volume 32, Issue 5, July 2024.
Knowledge on seed ecology is foundational for effective seed‐based restoration including seedling production, direct seed sowing, topsoil transplant, and natural regeneration. Consequently, quantifying available knowledge and biases in seed‐based research allows practitioners to better plan and implement seed‐based restoration programs and identify ...

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

Journal 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 ...

Brazilian embauba ( Cecropia pachystachya ) extract reduces renal lesions in 5/6 nephrectomized rats [PDF]

Journal of the Renin-Angiotensin-Aldosterone System, 2014
Introduction: Cecropia pachystachya (CP) is a plant rich in polyphenols which inhibits the angiotensin-converting enzyme (ACE) in vitro. Angiotensin II (AII) has an important role in the renal lesion provoked by 5/6 nephrectomy (NE). This study evaluated the CP extract effect on renal lesions provoked by 5/6 NE.

Cardiotonic and sedative effects of Cecropia pachystachya Mart. (ambay) on isolated rat hearts and conscious mice

Journal of Ethnopharmacology, 2006
Cecropia pachystachya Mart. is popularly called "ambay" and extensively used in herbal medicine of South America for cough and asthma. In Argentina it grows in neotropical rainforest (Ntr C.p.) and in a temperate region (Tp C.p.). In a previous work we showed their hypotensive properties with different potency and toxicity, and now we studied the Tp C ...
