Checklist of Orchidaceae From Brazilian Amazon Restingas

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 3, September 2026.
In Brazil, restingas (coastal sandbank vegetation) are distributed along the coast in the Atlantic Forest, Caatinga, Cerrado, and Amazon phytogeographic domains. Orchidaceae is one of the botanical families with the greatest species richness in restingas in the Atlantic Forest but has been poorly documented in Amazonian restingas, resulting in limited ...

17‐epi‐Melianodiol, a new protolimonoid from Melia azedarach fruits, exhibits larvicidal activity and is associated with oxidative imbalance and midgut epithelial damage in Aedes aegypti larvae

open access: yesPest Management Science, Volume 82, Issue 9, Page 9240-9248, September 2026.
The bio‐guided phytochemical study resulted in the new compound 17‐epi‐melianodiol. The compound eliminated 100% of Aedes aegypti larvae at 100 ppm, causing pronounced morphological changes, cuticular damage, and extensive vacuolization. Abstract BACKGROUND In Brazil, Aedes aegypti is the primary vector of arboviruses such as dengue, chikungunya ...

Ecological Assessments and Community‐Based Restoration: Co‐Designing a Vegetation Monitoring Protocol for Community Science in Mexico's Water Forest

open access: yesCommunity Science, Volume 5, Issue 3, September 2026.
Abstract Community science is a community‐led scientific mode of inquiry, sustained by social learning, for the purpose of transforming environmental governance. We present a case study of a community science initiative from Mexico's Water Forest, where a grassroots organization, the Milpa Alta Biological Monitoring Group, co‐designed a vegetation ...

Maximum water stress is decoupled from climate, traits, and growth in a xeric oak

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2392-2406, September 2026.
We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.

Global population structures and demographic history of Suillus luteus, a pine co‐introduced ectomycorrhizal fungus associated with exotic forestry and invasion

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2964-2979, September 2026.
Global phylogenomic tree and phylogenetic network of Suillus luteus and its closely related species. Summary Human colonization since the 19th century has resulted in the global spread of pines beyond their original northern boreal distribution. Although the introduction history of pines is documented through historical records, little is known about ...

HetCA/STOCSY‐Guided Dereplication of Artemisia arborescens Reveals Furofuran Lignans with Antileishmanial Effects

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Bioactive metabolites can remain hidden in negligible activity extracts. A statistical spectroscopy–driven dereplication workflow integrating the HeteroCovariance Approach (HetCA) and Statistical Total Correlation Spectroscopy (STOCSY) prioritized furofuran lignans in Artemisia arborescens, identifying three compounds with moderate antileishmanial ...

Valorization of Ficus carica Pruning Residues as Selective Botanical Insecticides: Optimized Furanocoumarin Extraction, Efficacy Against Neotropical Stink Bugs, and Mechanistic Insights via Molecular Docking

open access: yesArchives of Insect Biochemistry and Physiology, Volume 122, Issue 4, August 2026.
Optimized extracts from Ficus carica pruning waste exhibit strong biological activity against major stink bug pests. Complementary in silico analyses suggest this efficacy relies on pest‐specific acetylcholinesterase inhibition, predicting a promising, pollinator‐safe alternative for sustainable agriculture.

Discovery of VEGFR‐2 Inhibitors From Leonurus japonicus via Integrated Genetic Authentication, Molecular Networking, and In Silico Analysis

open access: yesArchiv der Pharmazie, Volume 359, Issue 8, August 2026.
Genetic authentication of Leonurus japonicus was confirmed using ITS sequencing. UHPLC‐MS/MS‐GNPS analysis and isolation led to a new labdane diterpenoid (1) and known compounds (2–6), with anti‐angiogenic activity validated by EPC assays and VEGFR‐2 docking studies.

Efficient Solketal Synthesis via Acetalization Using Sulfonated Carbon From Lavender Leaf Waste After Essential Oil Extraction

open access: yesChemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Sulfonated carbon catalysts were synthesized from lavender leaf waste after essential oil extraction via hydrothermal carbonization (HTC). Under mild, low‐energy conditions, the catalyst achieved 97% glycerol conversion and 98% solketal selectivity. This approach valorizes agricultural residues and crude glycerol from biodiesel production, contributing

Dicentrine, an Aporphine Alkaloid From Ocotea langsdorffii, Induces Mitochondrial Dysfunction and Oxidative Stress in Leishmania (L.) infantum

open access: yesChemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Dicentrine, an aporphine alkaloid, exhibits potent in vitro antileishmanial activity against Leishmania species with high selectivity and low macrophage cytotoxicity. Mechanistic studies reveal that the compound triggers parasite death possibly by inducing mitochondrial membrane disruption and oxidative stress.
