Vector Potential Index: Bridging Competence and Contribution as an Integrative Measure of Relative Transmission Capability

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
The Vector Potential Index (VPI) is a novel metric for evaluating and comparing the potential of blood‐feeding arthropod vectors to contribute to zoonotic vector‐borne disease transmission. Taking a meta‐analysis approach, the VPI combines vector competence and host use data obtained from scientific literature to assign relative and absolute VPI ranks ...

Plant Traits as Potential Drivers of Timber Value in the Dipterocarpaceae

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
This study examines how plant traits and wood density influence timber market value in Southeast Asia's Dipterocarpaceae family. Using a phylogenetic approach, it finds that higher wood density is linked to greater timber prices, while conservation status does not correlate with market value.
