Communities with diverse subsistence needs require a variety of functional tree traits

Conservation Science and Practice, EarlyView.
Malagasy forest users vary the traits that they prefer for different household uses. Accessibility is prioritized for daily uses such as fuelwood, while functional traits are valued for longer‐term uses. Differences between men and women reflect traditional gender roles.

Optimization and predictive modelling of biodiesel production from waste cooking oil catalyzed by blast furnace slag geopolymer using RSM and machine learning

The Canadian Journal of Chemical Engineering, Volume 104, Issue 1, Page 6-30, January 2026.
Abstract Biodiesel production from waste cooking oil (WCO) has emerged owing to growing interest in sustainable energy sources. Geopolymers synthesized from industrial wastes, such as blast furnace slag (BFS), are promising catalysts because of their environmental benefits and catalytic properties.

Biogeochemical asymmetry and the diversification of tropical rain forests in Borneo: The endmember hypothesis

Functional Ecology, Volume 40, Issue 1, Page 4-14, January 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mixed dipterocarp lowland tropical rain forests on Oxisols and Ultisols and heath forests on Spodosols are considered distinct vegetation types in Borneo. Here we present the endmember hypothesis of ecosystem diversification, which describes a continuum of forest ...

Megafaunal Rodents: Behaviour and Ecological Roles of Southeast Asian Forest Porcupines

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Southeast Asian porcupines (Malayan porcupine, Hystrix brachyura; brush‐tailed porcupine, Atherurus macrourus) performed at least four important ecological roles in a Malaysian rainforest. Burrows of both species were used in several ways by at least 22 animal species, while the soil above was potentially good sites for seedling recruitment. Porcupines
