Le régime alimentaire du rat noir (Rattus rattus) dans les îles d’Hyères analysé par la biochimie isotopique et les contenus stomacaux
The diet of the Black Rat from three islands (Port-Cros, Porquerolles and Bagaud, South-East France) was studied using stomach content and stable carbon and nitrogen isotope analysis.
The results show that plant matter is present in winter in 71 % to 88 % of the analysed stomachs, depending on the island. In volume, leaves (17 species) account for 33,5 % of the stomach contents, fruits (7 species) 26,7 %, and seeds 8,53 %. Two species (Smilax aspera and Juniperus phoenicea) are...
