Sampling sites on the CSIRO Black Mountain campus are situated within a mosaic of native eucalypt woodland and semi-urban environments, characterised by open forest structure, managed landscapes, and proximity to research infrastructure. These sites support a diverse assemblage of native and introduced vertebrate species typical of southeastern Australian urban bushland.\n\nAdditional sampling was conducted at a zoological facility in Canberra, representing a managed environment with spatially structured enclosures and known vertebrate assemblages. This setting provides a semi-controlled context for evaluating airborne eDNA detection against expected species presence.","designDescription":"This study employed a series of experiments to evaluate how key sampling design parameters influence airborne eDNA detection using passive sampling devices. \n\nThe experimental design focused on three primary factors: filter size (2.5cm2 or 5 cm2), sampling duration (1 hr to 2 weeks), and post-collection storage (immediate processing versus 28 day storage). These variables were tested across replicate sampling events to assess their effects on DNA capture, detection sensitivity, and vertebrate community recovery.\n\nSampling was conducted in natural environments as well as at a zoological facility with known species composition, providing a semi-controlled framework for interpreting detection patterns and validating airborne eDNA signals.","relatedProjects":[],"abstract":"This dataset supports a study evaluating how sampling design influences airborne environmental DNA (eDNA) detection using a simple, low-cost passive sampling device.

Sampling occurred over multiple deployment events spanning short-term (hours to days) and extended (up to several weeks) durations.\n\nAirborne eDNA samples were collected across replicated deployments designed to capture variation in temporal exposure, with sampling frequency structured around discrete experimental trials rather than continuous monitoring. These deployments encompassed a range of environmental conditions and repeated sampling events to assess temporal patterns in DNA detection.","sampling":"Airborne eDNA was collected using passive sampling devices designed to capture biological particles from ambient air onto fibrous filter material. Sampling was conducted across a series of controlled field experiments and zoo-based deployments to evaluate the effects of filter size, sampling duration, and post-collection storage on DNA capture and detection.\n\nSamplers were deployed in outdoor environments and at a zoological facility, with filters exposed for durations ranging from hours to several weeks. Replicated deployments were conducted across experimental conditions, and individual filters were treated as independent biological samples. Field blanks and negative controls were included to characterise background signal and potential contamination.\n\nDNA was extracted from filter material using protocols optimised for low-input environmental samples. Mammalian DNA was characterised using the Mam12 metabarcoding marker targeting mitochondrial 12S rRNA.\n\nHigh-throughput sequencing data were processed using a denoising pipeline to generate amplicon sequence variants (ASVs), followed by taxonomic assignment using reference database comparisons. Taxonomic assignments were curated using identity thresholds and biologically informed filtering criteria, and low-abundance detections were removed using a minimum read threshold.","methodSteps":[]},"countryCoverage":[],"collections":[],"dataDescriptions":[],"dataLanguage":"eng","pubDate":"2026-05-04T00:00:00.000+00:00","maintenanceUpdateFrequency":"UNKOWN","maintenanceDescription":"","license":"http://creativecommons.org/licenses/by-nc/4.0/legalcode","dwca":{"coreType":"http://rs.tdwg.org/dwc/terms/Occurrence","extensions":["http://rs.gbif.org/terms/1.0/DNADerivedData"],"modified":"2026-09-07T12:59:55.982+00:00"},"category":["eDNA"],"approximateCounts":{"occurrenceCount":1596}}
