Intraspecific plant chemodiversity at plot level has contrasting effects on arthropod functional groups

Functional Ecology, Volume 39, Issue 12, Page 3732-3750, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant chemistry mediates interactions between plants and their environment. While intraspecific chemodiversity at the individual plant level is well studied, the effects of chemodiversity at the plant community level on arthropod interactions need more attention.

Contrasting effects of vertebrate and invertebrate herbivores on leaf litter decomposition in terrestrial ecosystems: A meta‐analysis

Functional Ecology, Volume 39, Issue 12, Page 3372-3384, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivores influence litter quality, soil properties and decomposer communities, with cascading effects on litter decomposition. Vertebrate and invertebrate herbivores can affect decomposition through the same two pathways (litter quality‐ and soil‐mediated) but are ...

Histological and Gene Expression Analyses of the Arm and Finger Macroglands of Two Hyloxalus Frogs (Dendrobatidae)

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Chemical communication during courtship is well documented in salamanders and newts, but its role in frogs is less understood. In some Neotropical poison frogs, males exhibit specialised mucous glands (SMGs) in the hand integument that express high levels of sodefrin precursor‐like factors (SPFs), an amphibian pheromone. Some species also show

Distinct Intra‐ and Interspecific Foraging Patterns of Stingless Bee Species as a Conservation Tool

Biotropica, Volume 57, Issue 5, September 2025.
In this study, we examined the foraging patterns of three rescued stingless bee species in the Bolivian Yungas using melissopalynology and plant–pollinator network analysis. We found distinct floral foraging patterns both within and among three stingless bee species in the Bolivian Yungas, suggesting niche partitioning at multiple levels.

A Covalent and Modulable Inhibitor of the Tubulin‐Microtubule System: Insights Into the Mechanism of Cacalol

Chemical Biology &Drug Design, Volume 106, Issue 3, September 2025.
An oxidated form of cacalol, the methylenecyclohexadienone MTC (2), is generated under highly oxidant conditions, thus emulating the environment present in cancer cells. This species (2) is responsible for the inhibition of tubulin polymerization by promoting an irreversible binding interaction with Cys347 in α‐tubulin.

Do Formal Stance Strategies Reveal Disciplinary Variation in Professional Scientific Writing?

International Journal of Applied Linguistics, Volume 35, Issue 3, Page 1242-1261, August 2025.
ABSTRACT Stance in academic discourse has been extensively studied, with numerous investigations indicating that its expression varies across disciplines, depending on the authors’ intention to either enhance or diminish their voice or presence (e.g., It seems fairly certain vs. This is based on the belief that…).
