Wide variation in hydraulic safety margins across and within southern Amazon forests

Journal of Ecology, Volume 114, Issue 5, May 2026.
Site‐specific conditions and species identity were the main drivers of variation in Ψdry and HSM50 in southern Amazonian trees, but played a weaker role in explaining Ψ50. Ψpredawn strongly predicted HSM50. Across the Amazon, Ψ50_CWM and Ψdry_CWM became more negative with increasing MCWD, whereas HSM50_CWM showed no significant relationship with MCWD ...

Wasp and Ant Nests: Who Really Protects Whom? New Insights From Amazonian Forests

Austral Ecology, Volume 51, Issue 5, May 2026.
ABSTRACT Studies of animal behaviour are often biased towards species that are large‐bodied or have broad geographic ranges, as these are easier to observe in nature. Consequently, our understanding of behavioural ecology is shaped by such biases, even though these studies have provided important insights.

Description of Austrocelis gen. nov. (Diptera: Periscelididae), including the description of eight new species and the diversity and abundance of the species in different strata of the Amazon Rainforest

Austral Entomology, Volume 65, Issue 2, May 2026.
Abstract Austrocelis gen. nov. is described based on the following characters: maxillary palpus short and spatulate; setae of the head elongate; face protrudent, with the dorsal portion flattened and oblique, and ventral portion shorter and recessed towards the mouth opening; wing banded, with setae present on dorsal surface of vein R1; surstylus ...

Systematics of the New World Rostrate Genus Metaxyphloeus Thomas, 1984 (Coleoptera: Laemophloeidae): Morphological Evidence for Monophyly Supporting a Broader Generic Concept

Austral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT A morphology‐based MP analysis is undertaken to test the monophyly of the lined flat bark beetle genus Metaxyphloeus Thomas, 1984, as well as to hypothesize its intra‐ and intergeneric evolutionary relationships. Based on the results of the present work, Metaxyphloeus, as currently composed, is hypothesized as a monophyletic assemblage of ...

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 ...
