Local environment and sampling bias drive parasite prevalence estimates in freshwater fish communities

open access: yesOikos, Volume 2025, Issue 7, July 2025.
Parasite occurrence and infection estimates vary through time and space, making understanding the underlying drivers highly complex. Comparative studies based on empirical data must consider the factors of variation involved in estimating infection metrics in natural populations to make appropriate and reliable comparisons. Using a multi‐scale approach,

BioTIME 2.0: Expanding and Improving a Database of Biodiversity Time Series

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 5, May 2025.
ABSTRACT Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic ...

Evaluation of Trap Crops and the Presence of the Predator Nabis americoferus for the Management of the Tarnished Plant Bug in Strawberries

open access: yesJournal of Applied Entomology, Volume 149, Issue 3, Page 372-383, April 2025.
ABSTRACT The polyphagous tarnished plant bug (TPB), Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae), inflicts substantial damage to strawberries and to several other valuable crops, impacting both yield quantity and quality. Effective control strategies are crucial to mitigate these losses. This study aimed to elucidate TPB host preferences

Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) relating to an analysis of the health risks associated with exposure to caterpillars with stinging hairs and the development of management recommendations

open access: yesFood Risk Assess Europe, Volume 3, Issue 2, April 2025.
Abstract Several species of Lepidoptera with caterpillars bearing urticating hairs are increasing their range in metropolitan France from year to year, such as the pine processionary (Thaumetopoea pityocampa Denis et Schiffermüller 1775) whose presence was historically limited to the south of France, and which is gradually being observed in the north ...

Comparative gene expression analysis of differentiated terminal and lateral haustoria of the obligate root parasitic plant Phelipanche ramosa (Orobanchaceae)

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 2, Page 360-366, March 2025.
The parasitic weed Phelipanche ramosa thrives on a broad spectrum of cash crops over the Northern Hemisphere. Unfortunately, current management practices are inefficient in controlling its devastating impacts and spread. Here, valuable insights are provided on an understudied aspect of its biology, the formation of a feeding organ network on the ...

Crop age is the main driver affecting alfalfa mosaic virus: The predominant virus in the alfalfa virome

open access: yesAnnals of Applied Biology, Volume 185, Issue 3, Page 371-382, November 2024.
For the first time, we assessed the incidence and annual increase of Alfalfa mosaic virus (AMV) using a comprehensive approach that considers both local and landscape characteristics. Local context provided the most robust explanation for both the incidence and annual increase of AMV, with crop age being the main driver. Abstract The alfalfa virome has
