Contrasting Fe and Al controls on mineral-associated organic carbon across a tropical wetland toposequence in palm swamps (Vereda)

Caio Murillo Santana de ALMEIDA, Uidemar Morais Barral, Myller de Sousa Tonhá, Jeremie Garnier et autres

Wetlands are major global natural carbon reservoirs, yet the mechanisms controlling organic carbon persistence in tropical systems remain poorly constrained. In the Brazilian Cerrado, Veredas (groundwater-fed palm swamp wetlands) are characterized by strong hydrological gradients, dynamic redox conditions, and highly weathered soils. …

Neotropical cave entrances as environmental filters for vascular plant communities along low-light and soil resource gradients

Rafael Costa Cardoso, G. H. Rosa, Roberto Franco Junior, Diego Tassinari et autres

eotropical quartzite cave entrances harbour unexpectedly rich vascular plant communities shaped by steep light and soil-resource gradients. Across the forest–cave continuum, richness declines sharply with depth, while composition is governed by external forest structure, entrance geomorphology and sediment geochemistry. These ecotones act …

Neotropical Cave Entrances as Environmental Filters for Vascular Plant Communities Along Low‐Light and Soil Resource Gradients

Rafael Costa Cardoso, G. H. Rosa, Roberto Franco Junior, Diego Tassinari et autres

ABSTRACT Aims Cave entrances are low‐light, oligotrophic ecotones where vascular plants persist at the intersection of strong constraints imposed by light, moisture, and soil resources. Yet the processes structuring these communities in tropical regions remain poorly explored. We ask: (1) How do …

Open letter: Brazil at a crossroads—Protecting peatlands is essential for post‐COP30 climate leadership

Suelma Ribeiro Silva, Alexandre Christófaro Silva, Uidemar Morais Barral, Carlos Moreira de Souza et autres

This Open Letter highlights peatlands as critical yet overlooked ecosystems in Brazil's climate and biodiversity policies. By translating scientific evidence into clear, actionable priorities for policymakers, it supports more accurate climate reporting, effective mitigation strategies, and improved land-use governance. The letter emphasizes …

Development and Validation of High-Performance Soil-Cement Panels: A Sustainable and Economical Alternative for Civil Construction

Bernat Viñolas Prat, Demisson Renato Ferreira, Luís Guilherme Monteiro, João Vinícios Wirbitzki da Silveira et autres

Despite its advantages, conventional soil-cement has limitations in terms of mechanical strength and durability, especially in environments with high humidity or high structural demands. The development of high-performance soil-cement (HPSC) presents significantly superior mechanical properties. The decentralized production of these panels has …

Nickel Effects on Growth and Phytolith Yield of Grasses in Contaminated Soils

Enilson de Barros Silva, Múcio Mágno de Melo Farnezi, Lauana Lopes dos Santos, Alexandre Christófaro Silva et autres

Nickel (Ni) is extremely toxic to plants at high concentrations. Phytoliths have the potential to sequester the heavy metals absorbed by plants and act as a detoxification mechanism for the plant. The authors of the present study aimed to evaluate the effects …
