収集方法

Samples were collected using ARMS located at 25 metres of depth and 500 metres to “Mario Zucchelli” Research Station. Each ARMS consists of 10 PVC plates (22.5 x 22.5 x 0.5 cm) stacked one top of each other by a space of 1 cm nylon spacers at the corners of each plate, where four stainless steel bolts are threaded into, holding the entire structure together. This is then fixed on top of a large 45x35 cm PVC base plate, which allows the whole structure to be anchored to the seafloor by four stainless steel rods passing through large holes in the corners of the base plate. ARMS were deployed at sea for a different period, namely 1, 2, 3 and 5 years. These 6 structures were located in 2015 and were recovered in different years: 2 in 2016 (1 year later), 2 in 2017 (2 years later), 2 in 2018 (3 years later). In addition, one pair of ARMSs was installed in 2016 and recovered in 2021 (5 years later) and another additional pair of ARMSs was installed in 2017 and recovered in 2022 (5 years later).

Method step description:

1. ARMS have been recovered thanks to the help of PNRA SCUBA divers, which covered each retrieved structure with a rigid plastic crate perforated on each side and internally lined with a 100 μm nylon net, in order to avoid the escape of vagile benthic organisms.
2. The structures located in 2015 and recovered in 2016 (1 year), 2017 (2 years) and 2018 (3 years) were recovered and stored at a temperature of -20°C to be transported to Italy, where they were disassembled and processed. Each individual plate was appropriately photographed, from both sides, scraped and homogenized to form sub-samples that were subsequently stored in ethanol at -20°C. However, during the recovery of the first pair of structures (2016) and one of the second (2017), these crates malfunctioned and thus no analyses on the vagile component of the community inhabiting the ARMS could be performed. For the fifth-year structures, one pair located in 2016 and recovered in 2021 and the other pair located in 2017 and recovered in 2022, processing took place directly in Antarctica. The entire recovered structures were then covered in sterile plastic bags and preserved at -20°C until processing.
3. The samples were sorted, acquired by the Italian National Antarctic Museum (MNA, section Genoa) and directly stored in ethanol (96%) or at -20°C. to be identified later.
4. Most of the records were identified by one researcher, using original descriptions and taxonomic keys and online portal World Registry of Marine Species (WoRMS) to confirm acceptance of species names. The identification was often supported by taking pictures at the SEM photos and combining stack images of the analyzed specimens, particularly with the bryozoa phylum. For this taxon, a small portion of the colony of less than 1 cm was taken and treated with sodium hypochlorite (NaClO) for 10 minutes and washed with ethanol (EtOH) at different concentrations 70%, 90% and 100%. When identification was inconclusive, only genus or family names were assigned. The samples were deposited in the biological collection of the MNA. All data were uploaded to the GBIF portal.
