Using <scp>DNA</scp> metabarcoding to detect burrowing seabirds in a remote landscape

Species inventories and biodiversity assessments are critical to conservation. Yet cryptic species or recolonizing can be challenging detect. DNA metabarcoding provides an alternative tool identify that difficult observe during field surveys. We test the efficacy of analysis burrowing petrel in a rapidly changing landscape, on remote sub-Antarctic island following pest eradication. Discarded feathers scats provided high quality for identification, assisting detection new arrivals breeding sites across Macquarie Island. highlight how informs is valuable complement seabird
