Couverture géographique

The dataset comprises South America at latitudes beyond 40°S, which encompasses most of the Patagonian and sub-Antarctic Provinces and the classically defined terrestrial biogeographic regions of Antarctica. The latter include the core sub-Antarctic islands (South Georgia, Prince Edward Islands, Macquarie Island, Heard Island, Crozet, and Kerguelen Islands), maritime Antarctica (west coast of Antarctic Peninsula, South Shetland Islands, South Orkney Islands, South Sandwich Islands) and continental Antarctica. This updated version included Australia, New Zealand, New Caledonia, Tasmania records and one published record from Mongolia.

Couverture taxonomique

The present dataset reports occurrences of the genus Boeckella at species level.

Couverture temporelle

Données sur le projet

The present study provides an updated database of 37 species of Boeckella, using a combination of recent sampling data and published records available in the literature, giving a comprehensive description of the geographic distribution of the genus Boeckella at high latitudes in southern South America, the three main terrestrial biogeographic regions of Antarctica (sub-, maritime and continental), including Australasia, Mongolia and New Caledonia. We included new records from South Georgia and changed the taxonomic status of previous records.

Méthodes d'échantillonnage

Collections took place from the shoreline, scooping individuals from the water column of lakes, ponds and small pools using a zooplankton net at locations across sub-Antarctic islands (Crozet, Kerguelen and South Georgia), maritime Antarctic (i.e. islands at the west side of Antarctic Peninsula, South Shetland Islands and Signy Island), part of the sub-polar forest ecoregion and Falkland/Malvinas Islands. Samples were immediately preserved in ethanol (99%), other than a small number of collected specimens that were preserved using formalin (5%) for morphological analysis. GPS positions were recorded for each sample location.

Description des étapes de la méthode:

1. For taxonomic identification at species level, the fifth leg from male specimens was removed and observed under an inverted microscope at 10X and 20X for confirmation of diagnostic characters as described by Bayly (1992). All available information was collated from the scientific literature reporting sampling or taxonomic revision of Boeckella species in southern South America, the sub-Antarctic islands, maritime and continental Antarctic. We included Boeckella records from 1855 to 1997 listed in the historical review of Menu-Marque et al. 2000 and additional information available in the literature from 1997 to present. Only records including the geographic location (coordinates) or approximate (identifiable) location of reported samples were incorporated in the database. Regarding the records from this new updated version (Australia, Tasmania, New Zealand, New Caledonia and Mongolia), were collated from scientific literature (enlisted in this metadata) and from the dataset of Ian Duggan and Ian Hogg from University of Waikato through BOLD System. These authors obtained, identified and classified the specimens. There were changes in the classification of species rank in Falkland/Malvinas Islands, Punta Arenas and possible a new lineage in Hornos Is. (Cape Horn, South America). Manuscript with molecular and morphology analyses is in preparation.
