A review of non‐native scale insects (Hemiptera: Coccomorpha: Coccoidea) of Australia and the challenges in maintaining current and accurate pest lists

Austral Entomology, Volume 65, Issue 1, February 2026.
Abstract Over 870 species of scale insects, also called coccoids (infraorder Coccomorpha), have been recorded from Australia. Here, we systematically review literature, databases and collections to provide a revised assessment of non‐native species to Australia, for which we confirm those species that are introduced and extant in Australia (including ...

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

Conservation Science and Practice, Volume 8, Issue 2, February 2026.
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.

Trade‐Offs Between Carbon and Water Fluxes Along a Land Use Intensity Gradient in Southeast Asian Forests and Plantations

Global Change Biology, Volume 32, Issue 2, February 2026.
Increase land use intensity may enhance net carbon uptake in fast‐growing species on mineral soil but concurrently increases the risk of water scarcity. Net carbon uptake and evapotranspiration in high land use intensity sites are more affected by water availability compared to low land use intensity sites.

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 ...
