Descripción
This database is the result of an international collaboration effort to collect specimens of the Harpagifer genus throughout its geographical distribution in the Southern Ocean. More than 40 collection locations are incorporated along 3 biogeographic macro-zones (southern South America, sub-Antarctic Islands and Antarctica). Records are individualized by specimen, comprising more than 850 animals corresponding to 8 nominal species of the Harpagifer genus in the Southern Ocean. The purpose of this resource is to complement the molecular, taxonomic and biogeographic studies that are being carried out based on these specimens.

Cobertura geográfica
The dataset comprises three macro-geographic regions of the Southern Ocean: southern South America (Pacific coast of Patagonia and Falkland Islands), sub-Antarctic islands (South Georgia, Marion Island, Kerguelen Island and Crozet), and Antarctica (Antarctic Peninsula, South Shetland Islands and Signy Island). The northern end of the geographic coverage in South America is located south of the gulf of Penas, while the southern limit of the sampling range corresponds to Carvajal Base on Adelaide Island, Antarctica.

Datos del proyecto
This project seeks to understand biogeographic patterns of the Southern Ocean fauna based on their past and present interactions throughout different geographical areas. Through traditional and genomic molecular tools we intend to deliver insights regarding the climatic, oceanographic and tectonic processes that have marked the development and evolution of the Southern Ocean fauna. Under this framework this particular resource focuses on one of the most remarkable processes of diversification in the Antarctic realm, the evolution of the cold-adapted notothenioid fishes. While most of the teleost groups were completely eradicated from Antarctica, this suborder dominates in diversity, abundance and biomass. The evolutionary success of the Notothenioidei at sub-zero ecosystems has been explained by the presence of antifreeze glycoproteins (AFGPs), a key innovation in this Antarctic group. In particular, recent molecular study indicated that the most species-rich lineages within the notothenioids diversified and evolved during the late Miocene (11.6 to 5.3 My), 10 My after the acquisition of AFPGs. However, most of these studies have been biased toward the relationships within the Antarctic Clade rather than in the association among phylogenetic closed taxa found inside and outside the Polar Front. Therefore, the evolutionary history of non-Antarctic notothenioids remains not well-established, even if AFGPs genes in temperate-water nototheniids can be used to infer an Antarctic evolutionary origin. Under the framework of this project, Harpagifer presents itself as an interesting model. Harpagiferidae is a monogeneric family with 12 nominal species restricted to the Southern Hemisphere widely distributed in the Southern Ocean.

| Descripción del área de estudio | This project covers the different geographical areas of the Southern Ocean: South America (Patagonia and Falkland Island), Antarctica (Antarctic Peninsula and South Shetland Islands), Scotia Arch (South Georgia and Signy Island), and sub-Antarctic islands (Marion Island, Kerguelen Island and Crozet). Although this resource focuses on Harpagifer species, the research project has a broader scope, including representatives of the Crustacea, Equinodermata and Mollusca groups, and several other taxa using metagenomics. |
| Descripción del diseño | This project will underpin future comprehensive biogeographic processes in different species, including the use of phylogeographic approaches to evaluate the impact of the Quaternary glacial cycles in each of the analyzed Southern Ocean macro-zones. It will be possible to determine the effects of Quaternary glacial cycles over the distribution of genetic lineages in these species and it will be possible to estimate whether the Antarctic species remained in refugia along the Antarctic Peninsula during the last glacial event or re-colonized this area after the LGM from northern Antarctic Islands in the Scotia Arc. |

Métodos de muestreo
Due to the fact that the sampling was carried out by various groups of researchers, the sampling methodology presents variations related to field team and the particular conditions of each collection site. With this in mind, we can generalize the sampling protocol as described in "Methods steps".
| Área de Estudio | This dataset gathers several sampling efforts made between 2004 and 2019 in different locations from west side of Antarctic Peninsula (i.e.Doumer Island and Margarite Bay) and the South Shetland Islands (i.e. King George Island, Deception Island and Greenwich Island); the Scotia Arc Islands (Signy Island and South Georgia); sub-Antarctic Islands (Marion Island, Kerguelen Island and Crozet Island); and southern South America, including Pacific coast of Patagonia and Falkland Islands. |
|---|---|
| Control de Calidad | Records lacking precise geographic location (coordinates) were assigned georeferences by identification from the description (e.g. bay names, research stations) of the reported collection locality included in the relevant metadata. |
Descripción de la metodología paso a paso:
- Field sampling: Animals were collected by hand in intertidal pools during low tide periods and by SCUBA diving between -1 and -15 meters deep. In some (minor) cases, samples were obtained by bottom trawl (not deeper that -60 m). After collection, live animals were anesthetized and preserved in ethanol 95%. GPS position were recorded for each sample location.
