2026-06-23 Supporting data for "Integrating fecal DNA metabarcoding and environmental DNA to quantify stage-specific foraging selectivity in a threatened piscivorous bird" doi:10.57760/sciencedb.40711 en This dataset supports the findings of the research article entitled "Integrating fecal DNA metabarcoding and environmental DNA to quantify stage-specific foraging selectivity in a threatened piscivorous bird". The dataset is organized into two main components: 1. Raw Data​Primary sequencing outputs and processed biodiversity tables, including ASV (Amplicon Sequence Variant) tables derived from fecal DNA metabarcoding and environmental DNA (eDNA) analysis, along with taxonomic assignment files. 2. Analysis Code​Complete R scripts to reproduce all statistical analyses and visualizations, including species accumulation curves (sample-based rarefaction), data cleaning, diversity indices calculation, PERMANOVA, PCoA ordination, and indicator species analysis.
