    “…This study compared sediment assemblages from two coves, near Rothera Point, Antarctic Peninsula, 67°S in order to understand the principal drivers of community structure, for the first time, evaluating composition across all size classes from mega- to micro-fauna. RESULTS: Morpho-taxonomy identified 77 macrofaunal species with densities of 464–16,084 individuals m(−2). eDNA metabarcoding of microfauna, in summer only, identified a higher diversity, 189 metazoan amplicon sequence variants (ASVs) using the 18S ribosomal RNA and 249 metazoan ASVs using the mitochondrial COI gene. …”

    “…Using currently available species data, we found the current effectiveness of Egypt’s protected areas for conserving fauna was low. CONCLUSIONS: For SCP to be useful, there is a lower limit on data quality, requiring data-poor countries to improve sampling strategies and data quality to obtain unbiased data for as many taxa as possible. …”
