All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description

These data are mainly based on a paper by Phil Pugh (Pugh 2004, Biogeography of spiders on the islands of the Southern Ocean, Journal of Natural History, 38:1461-1487), but has been updated for Subantarctic and Antarctic regions. The names of people who have contributed to this update are listed in the dataset.

The data are presented in a series of worksheets in an excel file.

The introduction worksheet provides some basic information about the dataset.

The references worksheet is a list of references from Pugh's paper that he cited as well as more recent references. It also has some notes on the dataset.

The initial table worksheet is table 1 from Pugh (2004)

The antarctic-subantarctic worksheet are data retrieved from Pugh's (2004) table 1 specifically for subantarctic and Antarctic regions. These data have been checked and updated for the region.

The transposed antarc-subantarctic- worksheet are selected data from Table 1 transposed.

From the abstract of the Pugh paper:

The araneofauna of the extreme Southern Hemisphere is highly impoverished and disharmonic. Four dead anthropogenic immigrant spiders have been collected from Antarctica while only 115 verified species from 26 families are reported on islands of the Southern Ocean. Cluster analysis of the verified Southern Ocean species distribution data identifies a weak, but distinct, Neotropical/South Atlantic association together with robust South Indian and South Pacific biogeographic clusters. These groupings, largely attributed to vicariance and/or endemism, contain little evidence of post-Pleistocene dispersal. Indeed the 14 records of anthropogenic origin suggest that the pace of recent human-mediated introduction has been at least 30 times more rapid than that of Holocene natural dispersal.

Quality

Records that were considered dubious by Pugh have been removed.

The dates provided in temporal coverage are approximate only.

From Pugh: The Southern Ocean is here delimited by the 45 degree S parallel, but omitting temperate southern South America, Stewart Island and South Island New Zealand. The Chatham Islands (44 degrees S) are close enough to the 45 degree S parallel to warrant inclusion.
