Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

open access: yesJournal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Pollinator community composition and pollen resource use in calcareous grasslands under different landscape contexts across Europe

open access: yesJournal of Animal Ecology, EarlyView.
In this paper, we show that pronounced differences in pollinator communities exist between grasslands embedded in contrasting agricultural landscape contexts. Opportunistic foraging strategies of most pollinators resulted in large interaction turnover, but these shifts did not translate into major changes in overall network structure, most likely as a ...

Taxonomic and functional diversity of noctuoid moths in a Mediterranean coastal area: implications for dune conservation in a long‐term ecological research eLTER site

open access: yesInsect Science, EarlyView.
This study investigates the taxonomic and functional diversity of noctuoid moths in a protected coastal dune system in Central Italy, revealing strong ecological associations between moth assemblages and dune zonation. Differences in species composition and trait attributes, along with the presence of habitat‐exclusive species, highlight the role of ...

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

South America holds the greatest diversity of native daisies (Asteraceae) in the world: an updated catalogue supporting continental-scale conservation

open access: yesFrontiers in Plant Science
Asteraceae is the world’s richest plant family and is found on all continents, in environments ranging from the coast to the highest mountains. The family shows all growth forms and, as in other angiosperm families, species richness is concentrated in ...

Art v 1 and Amb a 4 Co‐Sensitization Identifies Italian Patients at Risk for Mugwort‐Celery‐Spice Syndrome

open access: yesAllergy, EarlyView.
Three molecular profiles identified among Art v 1/Amb a 4‐sensitized patients: Art v 1 monosensitization, Amb a 4 monosensitization, and dual sensitization to both allergens. Art v 1 monosensitization was predominantly associated with allergic rhinitis, reflecting a classical airborne allergy pattern.

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Compositae‐ParaLoss‐1272: A complementary sunflower‐specific probe set reduces paralogs in phylogenomic analyses of complex systems

open access: yesApplications in Plant Sciences
Premise A family‐specific probe set for sunflowers, Compositae‐1061, enables family‐wide phylogenomic studies and investigations at lower taxonomic levels, but may lack resolution at genus to species levels, especially in groups complicated by polyploidy
