Impact of Plant Pre‐Processing on the Chemical Profile of Psidium guajava L. (Myrtaceae) Essential Oil and Evaluation of Its Bioactive Potential

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Leaf pre‐processing dictates the chemistry and bioactivity of Psidium guajava essential oil. Fresh leaves ground in a mixer showed a β‐caryophyllene‐rich sesquiterpene profile and the best safety, together with anti‐inflammatory, antioxidant and fungicidal activity against Candida species, including the emerging multidrug‐resistant Candida auris ...

Chemical Composition, Antioxidant and Antimicrobial Activities of Moroccan Equisetum ramosissimum Essential Oil and Butanolic Extract

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Moroccan Equisetum ramosissimum essential oil showed a distinct pulegone‐eudesmol‐rich profile and strain‐dependent antimicrobial activity, including against resistant isolates. The butanolic extract displayed stronger antioxidant activity in DPPH and β‐carotene bleaching assays, while docking suggested plausible interactions with selected microbial ...

DNA metabarcoding reveals key floral resources for native pollinators in post‐fire landscapes

Ecological Applications, Volume 36, Issue 7, October 2026.
Abstract Wildfires are a natural disturbance in dry ponderosa pine forest ecosystems, and are increasing in frequency and severity across western North America. The effects of wildfire on biotic and abiotic conditions have important implications for higher trophic levels, including native bees. We sought to quantify the responses of flowering plants to

Plastomes of Ten Blumea Species (Asteraceae): Comparative Analysis and Phylogenetic Relationships

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Comparative analysis of ten Blumea plastomes revealed conserved genome architecture and identified mutation hotspots and positively selected genes. Phylogenetic reconstruction clarified the genus's position within Inuleae and supported its monophyly. This study provides valuable genomic resources for Blumea. ABSTRACT Blumea (Asteraceae) comprises about

Automatic extraction of leaf characters from herbarium specimens

Taxon, 2012
Herbarium specimens are a vital resource in botanical taxonomy. Many herbaria are undertaking large-scale digitization projects to improve access and to preserve delicate specimens, and in doing so are creating large sets of images.

MICROWAVE DRYING OF HERBARIUM SPECIMENS

TAXON, 1985
SummaryThe authors propose the use of a microwave oven as a new rapid procedure for herbarium specimen drying. A comparison between the new method and the usual procedure is presented and discussed with regard to external appearance and morphological characteristics.

DNA from Herbarium Specimens

1994
Old, soft tissues from plants and fungi may be derived from many sources, including fossil beds (Golenberg et al. 1990; Soltis et al. 1992) and sites of human or animal habitation (Rogers and Bendich 1985), but by far the most voluminous sources of these tissues are dried herbarium collections.

PREPARATION OF OPUNTIA HERBARIUM SPECIMENS

Haseltonia, 2007
Abstract We present a best-practice method for preparing high-quality Opuntia herbarium specimens, from collection methods to storage. A botanical press having wide, thick, wooden boards is used for cladode drying. A layer consisting of corrugated cardboard, absorbent paper, newspaper, and a thin wood laminate is placed between each cladode.

On herbarium specimen images and artificial intelligence

New Phytologist
Summary Digitized herbarium specimens are increasingly used to train artificial intelligence (AI) models in plant identification and other botanical applications. The abundant specimen images available in public repositories are especially amenable to AI. For instance, digitized herbarium sheets are relatively standardized – generally
