Macquarie Island soil invertebrate survey

Soil cores were collected from numerous locations across the Macquarie Island Isthmus. Replicate samples were collected from each location and a single sample was collected from 50cm depth below the surface. Soil cores were cylindrical, diameter 70 mm, depth 70 mm and included surface vegetation where present. Invertebrates were extracted from the soil core using a heat gradient process. Specimens were preserved in ethanol following extraction.Invertebrates were identified under microscope to the lowest practicable level, which was species level for most taxa. Mites (Acarina) were identified to morphotype.Column labelsSample - Unique numerical sample identifierDepth - Depth of collection: surface = 0 cm, depth = 50 cm below surfaceLocation - Location identifier codeEasting - easting (m)Northing - northing (m)Elevation (m) - Height above sea level (m)Parisotoma insularis - Abundance of Parisotoma insularis in core sampleFolsotoma punctata - Abundance of Folsotoma punctata in core sampleTullbergia bisetosa - Abundance of Tullbergia bisetosa in core sampleCeratophysella denticulata - Abundance of Ceratophysella denticulata in core sampleHypogastrura viatica - Abundance of Hypogastrura viatica in core sampleHypogastrura purpurescens - Abundance of Hypogastrura purpurescens in core sampleCryptopygus antarcticus - Abundance of Cryptopygus antarcticus in core sampleCryptopygus caecus - Abundance of Cryptopygus caecus in core sampleCryptopygus lawrencii - Abundance of Cryptopygus lawrencii in core sampleCryptopygus tricuspus - Abundance of Cryptopygus tricuspus in core samplePolykatianna davidii - Abundance of Polykatianna davidii in core sampleLepidocyrtus sp. - Abundance of Lepidocyrtus sp. in core sampleMegalothorax sp. - Abundance of Megalothorax sp. in core sampleAcarina 1 - Abundance of Acarina 1 in core sampleAcarina 2 - Abundance of Acarina 2 in core sampleAcarina 3 - Abundance of Acarina 3 in core sampleAcarina 4 - Abundance of Acarina 4 in core sampleAcarina 5 - Abundance of Acarina 5 in core sampleAcarina 6 - Abundance of Acarina 6 in core sampleAcarina 7 - Abundance of Acarina 7 in core sampleAcarina 8 - Abundance of Acarina 8 in core sampleBig dark tick - Abundance of Big dark tick in core sampleSpider - Abundance of Spider in core sampleMicroscolex macquariensis - Abundance of Microscolex macquariensis in core sampleEnchytraeus albidus - Abundance of Enchytraeus albidus in core sampleNematode species - Abundance of Nematode species in core sampleStyloniscus otakensis - Abundance of Styloniscus otakensis in core sampleHarpacticoid - Abundance of Harpacticoid in core samplePuhuruhuru patersoni - Abundance of Puhuruhuru patersoni in core sampleStenomalium sp. - Abundance of Stenomalium sp. in core sampleThinophilus (fly) - Abundance of Thinophilus (fly) in core sampleAustralimyza - Abundance of Australimyza in core sampleGrasshopper? - Abundance of Grasshopper? in core sampleSlug sp. - Abundance of Slug sp. in core sampleThe easting, northing and elevation for each sample site was collected by Lauren Wise of the AAD and Josie van Dorst of the University of NSW using a Trimble differential GPS and the post processing was done by Dan Wilkins of the AAD. The elevations were derived using the global geoid model EGM96. To convert the eastings and northings of the sample sites to eastings and northings on the WGS84 datum of the Australian Antarctic Data Centre's GIS data representing the Macquarie Island station buildings and structures, add 1.40 metres to the eastings and 0.2 metres to the northings as given on page 3 of the survey report "Macquarie Island OSG Survey Campaign, Voyage 8 Round Trip, March 2002" by John VanderNiet and Nick Bowden of the Office of the Surveyor General, Tasmania.
