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 ...

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.

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.

How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

Ibis, Volume 168, Issue 2, Page 571-587, April 2026.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

New Phytologist, Volume 250, Issue 2, Page 873-884, April 2026.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

The role of tropical forest fragment vegetation in maintaining arthropod diversity and spillover to adjacent sugarcane fields O papel da vegetação de fragmentos de floresta tropical na manutenção da diversidade de artrópodes e na sua disseminação para campos de cana‐de‐açúcar adjacentes

Agricultural and Forest Entomology, Volume 28, Issue 1, Page 82-93, February 2026.
Tree diversity increases arthropod richness and the abundance of beneficial arthropod groups within Atlantic Forest fragments. Higher insect richness in forest fragments is associated with greater richness in adjacent sugarcane fields, and both habitats share insect families, suggesting spillover.

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.

Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests

New Phytologist, Volume 249, Issue 4, Page 1992-2009, February 2026.
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...

Mercúrio em Solos da Região Sudeste do Brasil sem Influência Antropogênica e sua Correlação com as Características Químicas e Físicas

Revista Brasileira de Ciência do Solo, 2015
A correlação entre as características físicas e químicas do solo e o teor de mercúrio natural é importante para identificar aquelas que mais influenciam na retenção desse elemento nesses solos e sua distribuição nos diversos compartimentos ambientais ...

Acidez do solo e calagem em pomares de frutíferas tropicais [PDF]

Revista Brasileira de Fruticultura, 2012
A produtividade agrícola nos trópicos é afetada, principalmente, pelos fatores ligados à acidez do solo (pH, saturação por bases, acidez potencial, disponibilidade de nutrientes). A calagem é uma prática bem conhecida para corrigir a acidez do solo em culturas anuais, ainda que não seja praticada com a regularidade necessária.
