Effects of elevation and microclimatic temperatures on butterfly–flower interaction networks in a Mediterranean mountain range

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 93-105, January 2026.
We tested how elevation and microclimate influenced butterfly–flower interaction networks at the hottest time of year in a Mediterranean mountain range. Interactions were dominated at all sites by one or two abundant butterfly and flower species, but butterfly networks were more robust to plant species loss at higher elevations. Nectar availability may

Phenolic compounds in species of the Blechnaceae

open access: yesPlant Biology, Volume 28, Issue 1, Page 282-291, January 2026.
The occurrence of caffeic acid derivatives in 32 species of Blechnaceae revealed differences in the presence of rosmarinic acid and blechnic acid B, a novel compound in ferns. Abstract Rosmarinic acid and other caffeic and 4‐coumaric acid derivatives are widespread in land plants.

Progestogens and androgens influence root morphology of angiosperms in a brassinosteroid‐independent manner

open access: yesThe Plant Journal, Volume 123, Issue 5, September 2025.
Significance Statement Plants produce progesterone and androgens, which alter root morphology in A. thaliana and 60% of tested angiosperms. Brassinosteroids seem uninvolved. Understanding the mechanism is like navigating an unknown city—exemplarily Dittelbrunn (a small village in Bavaria)—where the expected shortcut (interaction with brassinosteroids ...

Taxonomic and phylogenetic biases in translocated angiosperm plant species across European countries

open access: yesConservation Biology, Volume 39, Issue 4, August 2025.
Abstract Conservation translocations are a well‐known conservation tool used to reverse the effects of local population extinctions and restore ecosystems. Compared with mammals and birds, plants are underrepresented in translocation programs, and little is known about the potential taxonomic and phylogenetic biases of plant translocation efforts.

Melatonin Enhances Panax vietnamensis Resistance to Leaf Blight Pathogen Neofusicoccum ribis via the PvWRKY40–PvCOMT2 Module‐Driven Lignin Biosynthesis

open access: yesMolecular Plant Pathology, Volume 26, Issue 7, July 2025.
Panax vietnamensis synthesises melatonin to suppress PvWRKY40 expression, thereby relieving its repression of PvCOMT2. This derepression promotes lignin biosynthesis and enhances resistance to Neofusicoccum ribis. ABSTRACT Panax vietnamensis, a medicinally valuable perennial herb, is highly susceptible to leaf blight under cultivation; however, the ...

Osmoxylon‐like fossils from early Eocene South America: West Gondwana–Malesia connections in Araliaceae

open access: yesAmerican Journal of Botany, Volume 112, Issue 6, June 2025.
Abstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.

Review of larval food plant associations of the Agaristinae (Lepidoptera: Noctuidae) in Australia

open access: yesAustral Entomology, Volume 64, Issue 2, May 2025.
Abstract The Australian Agaristinae comprises a small group of predominantly diurnal moths with aposematic larvae and adults that are assumed to be unpalatable to most predators. A critical review of the larval food plants of this subfamily based on published records in the literature, together with unpublished records, is presented.

The Leaf Length-Width Method Is Applicable to Compound Leaves of Diverse Forms

open access: yesAgriculture
To estimate leaf area, the length-width method, also called the Montgomery equation, has been widely used. It is an empirical formula stating that within a given species, the area of a leaf is proportional to the product of its length and width. Although
