Sustainable treatment of banana leaves for phytosanitary applications: impact, spreading, and impregnation of mineral oil

open access: yesPest Management Science, Volume 82, Issue 6, Page 5555-5566, June 2026.
Mineral oil droplets spread anisotropically, penetrate banana leaf tissues, and diffuse into the palisade parenchyma, revealing a delayed, Fickian mechanism that supports improved phytosanitary spray strategies. Abstract BACKGROUND Efficient application of phytosanitary sprays is essential for sustainable control of foliar fungal diseases such as Black

High CO2 Under Nutrient Fertilization Increases Primary Production and Biomass in Subtropical Phytoplankton Communities: A Mesocosm Approach

open access: yesFrontiers in Marine Science, 2018
The subtropical oceans are home to one of the largest ecosystems on Earth, contributing to nearly one third of global oceanic primary production. Ocean warming leads to enhanced stratification in the oligotrophic ocean but also intensification in cross ...

Phylogenetic analysis and the recognition of a new genus for Mexican Crassulaceae segregated from Echeveria

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract Systematic knowledge of the Mexican Crassulaceae is slowly progressing as data from new DNA regions and species sampling efforts increase. We compiled and generated new rbcL, matK, rps16, ITS/ITS2, and ETS DNA sequences and performed an updated phylogenetic reconstruction for a group of 131 Mexican Crassulaceae terminals from 11 of the 13 ...

A phylogenomic framework for species delimitation in Kirganelia (Phyllanthaceae): Tracing a history of reticulate evolution

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract Kirganelia (Phyllanthaceae) is a palaeotropical genus recently reinstated as separate from Phyllanthus, yet species boundaries remain unclear, especially within the widespread and morphologically variable K. reticulata complex. To resolve this, we generated Angiosperms353‐based phylogenomic data from 233 samples and applied an integrative ...

Missing Summer Westerly Jet Barotropic Governor Effect Explains Climate Models—Observation Discrepancies in the Indian Monsoon Trends

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract The South Asian summer monsoon has exhibited a pronounced Northwest India‐Indo‐Gangetic Plains rainfall dipole since 1999, with northwest India experiencing a 24.6% increase, while rainfall in the Indo‐Gangetic Plain has decreased by 4.4%.

East‐West Variability in Nitrogen Sources Sustaining Pelagic Food Webs in the Subtropical North Pacific Ocean Revealed by Stable Isotopic Analyses

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Biological N2 fixation sustains pelagic ecosystems in subtropical oligotrophic waters. However, its impact on food webs as a nitrogen source remains poorly understood. Here, we quantified the contribution of diazotroph‐derived nitrogen to grazing food chains in the subtropical North Pacific in summer, where N2 fixation activity varies markedly

Response of the Nitrogen Isotopic Composition of Planktic Foraminifer Tissue to Surface Ocean Nutrient Cycling: A Case Study in the Northern South China Sea

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract This study presents data on geographically small‐scale patterns of nitrogen (N) isotope signals (δ15N) within the northern South China Sea (SCS) imprinted on planktic foraminifers (PF). PF from net tows on the shelf, continental slope, and in pelagic waters from summer 2019 were analyzed for δ15N.

Diagnosing Kinetic Energy Scaling Using Lagrangian and Eulerian Metrics in Different Dynamical Regimes of the North Atlantic

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract Understanding the multiscale dynamics of ocean surface turbulence requires diagnostics that reliably characterize variability at scales both larger and smaller than the Rossby radius of deformation. This study evaluates the consistency and interpretability of second‐order velocity structure functions derived from Eulerian and Lagrangian ...

Observed Trends and Variability in the Water Masses of the Southern Ocean

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract We present SatGEM‐2, a new version of the satellite gravest empirical mode (SatGEM) Atlas for the circumpolar Southern Ocean, incorporating all available CTD and Argo profile data through December 2022. SatGEM‐2 uses in situ hydrographic observations to construct static gravest empirical mode (GEM) fields in pressure–sea surface height (sea ...
