Kinetics of phosphorus sorption in soils in the state of Paraíba¹

Revista Brasileira de Ciência do Solo, 2011
The soil P sorption capacity has been studied for many years, but little attention has been paid to the rate of this process, which is relevant in the planning of phosphate fertilization.

Atributos do solo relacionados à adsorção de cádmio e cobre em solos tropicais

Acta Scientiarum. Agronomy, 2005
Soil attributes related to cadmium and copper adsorption in tropical soils. Chemical reactions and physical and biological processes control the adsorption of Cd and Cu by soils. Heavy metal retention by soils can decrease their bioavailability in the soil-solution system.

Climatic and Hydrological Changes Drive Contemporary Fire Regime Transitions in the World's Largest Wetland

Global Change Biology, Volume 32, Issue 9, September 2026.
Long‐term fire data (1985–2024) and integrated modeling reveal a climate and hydrology‐driven transition toward larger fires, increased burned area, and a longer fire season, indicating the emergence of a new fire regime in the Pantanal. ABSTRACT Tropical wetlands have historically been resilient to fire, but ongoing climate and hydrological changes ...

Atributos topográficos na diferenciação de Argissolos

Revista Brasileira de Ciência do Solo, 2013
A topografia do terreno controla muitos processos hidrológicos, geomorfológicos e pedológicos, influenciando a radiação solar, precipitação pluvial, escoamento superficial, evaporação, regime de umidade do solo e tipo de vegetação, entre outros.

Landscape configuration and soil properties shape ant‐mediated seed dispersal in tropical dry forest agricultural landscapes

Journal of Animal Ecology, Volume 95, Issue 8, Page 1476-1487, August 2026.
We show that ant‐mediated seed dispersal components respond differently to local soil conditions and landscape structure in Caatinga agricultural mosaics. Low‐intensity rainfed croplands maintained or enhanced seed removal compared to natural remnants, highlighting how small‐scale agriculture can sustain key ecological processes in human‐modified dry ...

Agrupamento dos acesso de feijão fava (Phaseolus lunatus) segundo os padrões SDS-PAGE e caracteres morfológicos - DOI: 10.4025/actasciagron.v25i1.2814

Acta Scientiarum. Agronomy, 2008
Feijões fava (Phaseolus lunatus) são bem adaptados a solos tropicais, especialmente a solos inférteis de áreas úmidas. Para verificar a diferença entre acessos de Phaseolus lunatus, 24 acessos foram caracterizados quanto à coloração de flor e de ...

Why Are Most Fish Populations Genetically Homogeneous Along the Southwestern Atlantic Coast? The Role of Life History Traits in Shaping Genetic Patterns

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Investigate patterns of population genetic structure in Southwestern Atlantic marine fishes and evaluate how geographic range, habitat diversity, and evolutionary history shape population connectivity. Location Southwestern Atlantic, including the Caribbean, Brazilian coast, and Patagonian region, between 0°59′ N and 40°16′ S.

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

Biotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

Environmental Contamination Affects Associated Bacterial Communities in a Neotropical Arboreal Ant

Biotropica, Volume 58, Issue 3, May 2026.
Environmental stressors such as contamination from mining tailings can alter microbial communities associated with insects, including social ants. Ants, as widespread and ecologically influential insects with stable microbial associations, offer a relevant model to examine these effects.
