Coevolution and Functional Effects of Endosymbiotic Rickettsia in Leptocybe invasa Fisher & LaSalle (Hymenoptera: Eulophidae) Across China

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Two distinct lineages of L. invasa and the dominant endosymbiont, Rickettsia, was identified, followed by an analysis of its infection density across various developmental stages and tissues of L. invasa. Furthermore, two distinct strains of the Rickettsia endosymbiont were detected, and the phylogenetic relationships between these strains and their L.

Uncovering the Key Factors Influencing Phytochemical and Phytopharmacological Properties During Medicinal Plant Processing

open access: yeseFood, Volume 7, Issue 1, February 2026.
From farm to pharma, this review details the engineering of quality in medicinal plants through a science‐driven approach: it first elucidates how genetic and environmental factors inscribe the plant's phytochemical and phytopharmacological profile before harvest, and then dissects the postharvest techniques and technologies—chemical and thermal pre ...

Assessing the Impact of Subsurface Clay Layers on Water Use Dynamics in Eucalyptus globulus Plantations

open access: yesHydrological Processes, Volume 40, Issue 2, February 2026.
Eucalyptus globulus sites underlain by thin clay layers exhibited substantially higher transpiration, groundwater use, and stand productivity compared to sites underlain by thick clay layers. Mean annual net water balance at thick clay sites was negligible. Access to groundwater was likely restricted by thick clay layers, resulting in reduced water use
