Descrição
This database presents a compilation of records in three species of genus Abatus. Records are individualized by specimens and collected by projects of different countries and dates. Therefore, this work aims to unify these samples and records, providing a description of geographical distribution of these three species in different macrozones (southern Patagonia, Subantarctic islands and Antarctica).
Registros de Dados
Os dados deste recurso de ocorrência foram publicados como um Darwin Core Archive (DwC-A), que é o formato padronizado para compartilhamento de dados de biodiversidade como um conjunto de uma ou mais tabelas de dados. A tabela de dados do núcleo contém 30 registros.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Cobertura Taxonômica
This dataset groups three species of Abatus genus belonging to Spantagoida sea urchin family

Dados Sobre o Projeto
These projects seek to test biogeographic, ecological, genetic and morphological hypotheses in different species of Antarctic and Subantarctic irregular sea urchins of genus Abatus.
| Título | Consequences of brooding development and ecological specialization on the persistence of Abatus populations and species in a changing Southern Ocean |

| Descrição da Área de Estudo | The study area corresponds to shallow waters in the infralittoral zone of the Antarctic and Subantarctic environments |
| Descrição do Design | To collect the samples two methods were used: 1) manual collection in the infralittoral zone at low tide, and 2) SCUBA diving between 1 to 15 meters deep at high tide. After collection, each individual was preserved in ethanol 95%, the geographic coordinates were recorded using GPS, and the samples were transported onboard or to the research station. Species identification was performed in the laboratory and following the taxonomic key “Antarctic Echinoidea” (http://echinoidea-so.identificationkey.org/mkey.html). Each sea urchin were observed and identified based on diagnostic morphological descriptors. |

| Área de Estudo | Samples were collected from Magellan Strait in southern South America. Samples from Kerguelen Islands were collected in the campaigns 1, 5, 8 and 9 of PROTEKER project. Samples from Malvinas Islands were collected during SAERI expedition. Antarctic material was collected from the South Shetlands Islands and Antarctic peninsula under the Antarctic Scientific Expeditions (ECA) 40, 42, 45, 47, 53, 56 and 60. |
|---|---|
| Controle de Qualidade | Manual sampling was carried out at random points in the study area. In the other hand, the SCUBA diving sampling points were systematically established with a separation of 500 meters in the study area. |

| Propósito | This dataset was created within the framework of the master thesis of the first author and part of the main research of the principal investigator. The main objective of the data set is built a baseline of the geographic distribution as a complement of the research on the biogeography of Abatus that is currently being carried out in the Laboratorio de Ecología Molecular (LEM) |
| Descrição da manutenção | The data set will be updated irregularly, and in relation to the authors' ability to collect and develop new relevant information. |
