Description
2561 individual polychaetes were collected from 266 sediment samples in the Oceanic Shoals Australian Marine Park between 2009 and 2012. The dataset, published by Geoscience Australia in 2019, includes 368 species and 43 families, providing a species-level inventory. It was used to examine variation in assemblages, relationships with environmental factors, and patterns across taxonomic and functional groups.
Use Cases
Analyzing polychaete community structure variation across surveys based on the species-level inventory.
Modeling relationships between polychaete assemblages and environmental variables or geomorphology.
Comparing ecological patterns at different taxonomic resolutions (species vs. family) and functional groups (feeding, habitat, mobility).
Establishing biodiversity baselines for small macrofauna to inform marine management strategies.
Strengths
Includes 2561 individual specimens and 368 identified species, providing a substantial species-level inventory.
Covers 266 samples from four distinct marine surveys conducted between 2009 and 2012.
Contains new species, genera, and family records for Australia (Iospilidae, Lacydoniidae), indicating novel findings.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment for specific analytical tasks.
