Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Uganda

open access: yesEFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the likelihood of pest freedom at entry in the EU, including both regulated and non‐regulated pests, potentially associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Uganda.

Quantitative Support for the Metabolic Load Hypothesis: Metabolic Rate Measures Reveal Host‐Dependent Growth Costs in a Polyphagous Herbivore

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
The metabolic load hypothesis was tested in Polygonia c‐album caterpillars by comparing metabolic costs across three host plants. Larvae feeding on a chemically challenging host showed higher energy demands per unit of growth and reduced performance.

Ant Diversity and Stratification in an Amazonian Rainforest

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
We examined the three strata of an Amazonian rainforest (e.g., the ground and leaf litter, understory and canopy) using only two sampling techniques and analyzed their functional traits. We identified 494 ant species from 10 subfamilies and 77 genera over ≈3.0 ha, showing that they are species rich and abundant, particularly at ground level.

Urtica dioica From El Menzel (Morocco): Phytochemical Analysis, In Vivo and In Silico Evaluation of Analgesic and Anti‐Inflammatory Effects, and Toxicological Study With ADME Profiling

open access: yesFood Science &Nutrition, Volume 13, Issue 12, December 2025.
The hydro‐ethanolic extract of Urtica dioica (yield 14.8%) contained 15 phenolics, mainly chlorogenic, caffeic, and p‐coumaric acids. The polyphenolic fraction (100 mg/kg, p.o.) significantly reduced acetic‐acid writhing (52%) and carrageenan‐induced edema (73%) without toxicity up to 4 g/kg.

Distribution of sex forms in the phanerogamic flora [PDF]

open access: yes, 2007
In the plant kingdom, particularly in the phanerogamic flora, hermaphroditism is by far the most common, yet the number of other sex forms is not negligible.

Ecological function over evolutionary legacy: The limited role of shared evolutionary history in shaping modern frugivory interactions

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3688-3703, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Frugivory, encompassing interactions between vertebrates and plants that range from mutualistic to antagonistic, drives seed dispersal and underpins the structure and resilience of tropical ecosystems.
