Seasonal diet partition among top predators of a small island, Iriomotejima island in the Ryukyu Archipelago, Japan

In general, small islands lack predators because species at higher trophic levels often cannot survive. However, two predators—the Iriomote cat Prionailurus bengalensis iriomotensis, and the Crested Serpent Eagle Spilornis cheela perplexus—live on Iriomotejima Island in the Ryukyu Archipelago, which covers an area of approximately 284 square kilometers. To understand how these two top predators coexist on such a small island with limited resources, we focused on their seasonal feeding habits which are considered crucial for survival in such an island ecosystem. To compare the diets of the Iriomote cat and Crested Serpent Eagle, we used DNA metabarcoding analysis of their fecal samples. In the summer, we identified 16 prey items from Iriomote cat fecal samples, and 15 Crested Serpent Eagle fecal samples. In the winter, we identified 37 and 14 prey items, respectively. Using a non-metric multidimensional scaling (NMDS) and a permutational multivariate analysis of variance (PERMANOVA), our..., , , # Data from: Seasonal diet partition among top predators of a small island, Iriomotejima island in the Ryukyu Archipelago, Japan

## Description of the data and file structure

\"no_sequencing_reads_primer name.csv\" contains the number of sequencing reads for each prey taxon in each fecal sample from each primer set after taxonomic profiling. These data were used to calculate the values described in Figure 3.

\"presence_absence_taxonomic level.csv\" includes the presence/absence data of each prey taxon integrated with all primer information at each taxonomic level. \"metrix.pdf\" shows how to calculate FOO and wPOO using above csv files. \"presence_absence_class.csv\" level was used to calculate the values descripted in Figure ...
