Extracts From Grapefruit (Citrus paradisi) Peel via Microwave‐Assisted and Conventional Extractions: Evaluation of Nosema Infection and Toxicity in Honey Bees

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Conventional and microwave‐assisted extractions of grapefruit peels were optimized using response surface methodology (RSM) based on TPC, TFC, and antioxidant activity (DPPH). The phytochemical profiles of the two optimum extracts were characterized via HPLC before evaluating their acute and chronic toxicity, as well as their effects on honey bee (Apis

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

Enzymatic synthesis of bioactive quinolones and (thio)coumarins by fungal type III polyketide synthases

open access: yesThe FEBS Journal, Volume 293, Issue 9, Page 2673-2691, May 2026.
Quinolones are valuable scaffolds for drug discovery but are rare in nature. Here, we show that two fungal enzymes, AthePKS and FerePKS, can generate 2‐quinolones and two additional heteroaromatic scaffolds. Using AthePKS, we designed an artificial enzymatic cascade towards an antimicrobial quinolone from a simple precursor and implemented it in E ...

Year‐round pollinator visitation of ornamental plants in Mediterranean urban parks

open access: yesInsect Conservation and Diversity, Volume 19, Issue 3, Page 702-715, May 2026.
Pollinators visiting ornamental plants in urban parks remained diverse throughout the year. They were represented by wild bees (42%), honeybees (37%), flies (18%), butterflies (2%) and beetles (1%). Both native and non‐native plants attracted pollinators.

Systematic anatomy of the woods of the Burseraceae

open access: yesLilloa, 2021
The author describes the anatomy of the Burseraceae log and compares it with that of Anacardiaceae, Rutaceae, Simaroubaceae and Meliaceae. The similarities in the structure of his logs suggest the possibility of a common origin; those of Meliaceae show ...

Disposition of two names in Almeidea (Rutaceae) Disposição de dois nomes em Almeidea (Rutaceae)

open access: yesActa Botânica Brasílica, 2010
Examination of type specimens at the P herbarium showed that Almeidea longifolia A. St.-Hil. (Rutaceae) is an illegitimate substitute name for A. affinis A. St.-Hil. The latter name is proposed here as a heterotypic synonym of A. rubra A.

AlkaPlorer: A database‐driven explorer for natural alkaloids and derivatives

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 5, Page 1384-1398, May 2026.
The alkaloid database AlkaPlorer integrates over 130,000 compounds across 12,250 species. By linking chemical structures with biological and evolutionary data, it reveals how these molecules evolve and function. This platform serves as a vital resource for AI‐driven discovery in plant metabolism and modern drug development. ABSTRACT Alkaloids, renowned
