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.
