Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change [PDF]
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Mapping the density of giant trees in the Amazon [PDF]
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

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

This article aims to analyze the main distribution channels in the productive chains of tropical flowers in Pernambuco state, focusing on the factors that influence its insertion into the European market. The European Union is the main destination for the tropical flowers exported by Pernambuco, responding for 99, 12 % of the total sales to foreign ...

A adubação com silício pode aumentar a produtividade pelo aumento da resistência ao acamamento, ao estresse hídrico e a desidratação após a colheita. O objetivo deste trabalho foi avaliar a produtividade e a qualidade pós-colheita de Helicônia Golden ...

Ant‐hemipteran mutualistic networks in cocoa crops maintain a stable structural organization across different microhabitats (flowers, leaves, and fruits) and management types. This stability is not intrinsic to the network, but rather an emergent result of the behavior of a few generalist ant species acting as structural buffers.

The frequency and importance of polyploidy in tropical rainforest tree radiations
Summary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...
