Chemical profile analysis of the essential oil of Peperomia mendanhensis: a newly described species from the Brazilian Atlantic Forest

Rodriguésia
The genus Peperomia (Piperaceae) encompasses approximately 1,700 species and has pantropical distribution, being most diverse in the Neotropics. Despite its taxonomic richness, many species remain chemically uncharacterized, limiting our understanding of

Secondary Metabolites Composition and Their Histochemical Localization in the Fruit of Piper malgassicum Papini, Palchetti, Gori and Rota Nodari (Piperaceae)

Chemistry &Biodiversity, Volume 22, Issue 11, November 2025.
ABSTRACT The anatomy, histochemistry, and secondary metabolite composition were investigated on the drupes of Piper malgassicum, one of the components of the spice voatsiperifery pepper. The high amount of piperine recorded with high‐performance liquid chromatography with photodiode‐array detection analysis was localized with histochemistry mainly ...

The Effects of Protected Areas in Nepal as a Barrier Against Plant Invasions Are Associated With Lower Propagule Pressure and Less Intensive Disturbance

Diversity and Distributions, Volume 31, Issue 9, September 2025.
ABSTRACT Aim Protected areas are established to conserve global biodiversity threatened by various factors, including invasive plants. We recorded naturalised alien plants inside and outside of protected areas to test whether they act as a barrier against the spread of alien plants.

Characterizing brown marmorated stink bug, Halyomorpha halys Stål, host plant usage and acceptability: Methodological strengths and shortcomings

Entomologia Experimentalis et Applicata, Volume 173, Issue 5, Page 403-416, May 2025.
We compared three tools for assessing invasive brown marmorated stink bug, Halyomorpha halys (Hemiptera: Pentatomidae), host plant usage. Baited traps were deployed to measure populations in tree canopies but found no differences. We tagged insects to track their retention on fruit hosts using harmonic radar; peach and baited apple trees were ...

Impact of Anthropogenic Pollution on the Plant Species Diversity and Composition Along the Riparian Ecotones of Goa's Sal and Zuari Rivers

Plant-Environment Interactions, Volume 6, Issue 2, April 2025.
ABSTRACT Anthropogenic pressures are increasingly constraining the health of riparian ecosystems by exposing their remnant vegetation to edge effects. Despite being at the land–water interface, conservation efforts have often overlooked how water pollution may indirectly exacerbate the broader impacts of anthropogenic pressures on riparian vegetation ...

Computational metabolomics reveals overlooked chemodiversity of alkaloid scaffolds in Piper fimbriulatum

The Plant Journal, Volume 121, Issue 5, March 2025.
SUMMARY Plant specialized metabolites play key roles in diverse physiological processes and ecological interactions. Identifying structurally novel metabolites, as well as discovering known compounds in new species, is often crucial for answering broader biological questions.

Naturally‐occurring nematicides of plant origin: two decades of novel chemistries

Pest Management Science, Volume 81, Issue 2, Page 540-571, February 2025.
A review of structure–activity correlations for 262 plant‐derived nematicidal compounds for controlling plant parasitic nematodes is presented. Chemical structures, sources, and isolation procedures are summarized based on the major chemical groups. Abstract Plant‐parasitic nematodes are among the most destructive plant pathogens, resulting in a global
