Pest categorisation of Pantoea ananatis

EFSA Journal, Volume 21, Issue 3, March 2023., 2023
Abstract The EFSA Plant Health Panel performed a pest categorisation of Pantoea ananatis, a Gram‐negative bacterium belonging to the Erwiniaceae family. P. ananatis is a well‐defined taxonomic unit; nonetheless, its pathogenic nature is not well defined and non‐pathogenic populations are known to occupy several, very different environmental niches as ...

Implementation and Use of Green Manures for Weed Suppression in Sequential Maize Cropping

International Journal of Agronomy, Volume 2023, Issue 1, 2023., 2023
The ground cover produced by green manures has a direct influence on weed suppression and, in addition, the biomass produced by these same plants influences crop growth. This study was carried out to compare the effect of green manure species on the incidence of weeds, in sequence, in order to evaluate the effects of the use of green manure cover on ...

Impacts of herbivory by ecological replacements on an island ecosystem

Journal of Applied Ecology, Volume 59, Issue 9, Page 2245-2261, September 2022., 2022
Due to a negative correlation in tortoise and skink dietary preferences and minimal overlap in the most frequently consumed taxa, the presence of tortoises is unlikely to have detrimental impacts on Telfair's skinks. Tortoise presence is likely to be beneficial to skinks in the long term by increasing the extent of palm‐rich habitat. Although tortoises

DNA metabarcoding reveals introduced species predominate in the diet of a threatened endemic omnivore, Telfair’s skink (Leiolopisma telfairii)

Ecology and Evolution, Volume 12, Issue 1, January 2022., 2022
Telfair's skinks are keystone omnivores found on Round Island, Mauritius. Using a multimarker DNA metabarcoding approach, we identify that this endemic species frequently consumes introduced species, which comprise almost 50% of all prey detections.
