Herbivores just need a calm place to feed: Ants cannot help them

open access: yesEntomological Communications, 2020
Why do herbivores, like Coelomera sp., seek to consume leaf tissue of Cecropia pachystachya colonized by Azteca alfari Emery, 1893 if they are at risk of being attacked by these ants?

Pentacyclic Triterpene Profile and Its Biosynthetic Pathway in Cecropia telenitida as a Prospective Dietary Supplement

open access: yesMolecules, 2021
Promising research over the past decades has shown that some types of pentacyclic triterpenes (PTs) are associated with the prevention of type 2 diabetes (T2D), especially those found in foods.

Wood anatomical trait correlations with hydraulic efficiency and safety in an aseasonal wet tropical forest

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Xylem anatomy underpins the capacity of trees to transport water while avoiding hydraulic failure, shaping species performance and resilience to climate change. However, the specific ways anatomical traits underpin hydraulic trade‐offs in tropical forests remain debated.

Multiple effects of mutualistic ants improve the performance of a neotropical ant-plant: A long-term study with the Cecropia-Azteca system

open access: yesBasic and Applied Ecology, 2021
Abstract Comprehension of the benefits involved in mutualisms is crucial to disentangle the role of interactions in the structure and functioning of populations, communities and ecosystems. In ant-plant mutualisms, benefits provided by plants to ants are immediately recognizable, but reverse benefits are less obvious, conditional and accumulate over ...

The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...
