Données sur le projet
This proposal aims to understand biogeographical patterns and the processes responsible of the origin, adaptation and diversification of the Southern Ocean (SO) biota, particularly of two chironomid midges. We will study the role of historical climatic changes and life-history traits in the distribution of genetic lineages across a latitudinal gradient. We will amplify specific mtDNA and nucDNA markers, identify and characterize genomic and transcriptomic novelties associated to the adaptation of the biota in different areas and will conduct studies of ecophysiological performance and tolerance in the selected taxa including major environmental variables such as temperature. We aim to better understand about the processes involved in the origin, diversification and resilience of the SO biota in space and time.

| Description du domaine d'étude / de recherche | This project will be conducted along a latitudinal and environmental gradient expanding from the southern tip of South America in the sub-Antarctic Magellanic ecoregion, through the Scotia Arc and maritime Antarctic islands. |
| Description du design | The study was conducted throughout the latitudinal and environmental gradient that includes the southern tip of South America in the sub-Antarctic Magellanic ecoregion (54-57°S), and the Scotia Arc distribution of P. steinenii in the sub-Antarctic (South Georgia, 53-54°S) and Maritime Antarctic (South Shetland Islands, 63-64°S) regions. The geographical range of the study involves both small-scale microhabitat environmental gradients and the larger spatial scale 10-degree latitudinal gradient. In the maritime Antarctic South Shetland Islands, we specifically surveyed ice-free areas on Deception, Livingston, Greenwich, Robert, Nelson, and King George Islands. In the north-west coast of Antarctic Peninsula, we surveyed the Trinity Peninsula and Litchfield Island. In the CHBR, we surveyed altitudinal gradients located along the north coast of Navarino Island, in Horn Island and the Diego Ramirez archipelago. Parochlus steinenii was found throughout the study area excepting the Diego Ramírez archipelago and the two locations along the north-west coast of the Antarctic Peninsula. Note that, more widely, the species has never been recorded in extensive terrestrial/freshwater studies from any location along the Antarctic Peninsula or from the South Orkney Islands (Chown & Convey, 2016). Fieldwork in the Antarctic was conducted during six austral summer seasons (2013/14 – 2018/19) during field expeditions organized by the Chilean Antarctic Institute (INACH) to the South Shetland Islands and the British Antarctic Survey to South Georgia. In the Magellanic sub-Antarctic region of southern Chile (in the CHBR), fieldwork was organized by the Sub-Antarctic Biocultural Conservation Program of the Universidad de Magallanes. To characterize the distribution of P. steinenii in the South Shetland Islands, we conducted intensive surveys throughout accessible ice-free areas. All accessible sites were sampled for a period of 4-6 h, depending on climatic conditions and logistic support. We additionally sourced all available information from the existing literature (see Wirth & Gressitt, 1967; Brundin, 1970; Allegrucci et al., 2006; Hann & Reinhard, 2006; Toro et al., 2006; Rico & Quesada, 2013). We assessed the presence/absence of P. steinenii (as larvae, pupae or adults) by searching close to the shoreline of lakes and streams, and specifically under rocks and vegetation, and in sediments. |

Méthodes d'échantillonnage
To determine the presence of Parochlus steinenii through the areas described, intensive field surveys were conducted through accessible ice-free areas. At each surveyed location, all accessible rivers, streams, lagoons and lakes were searched in detail over a period of 3-6 h, depending on the weather conditions and local logistics. Presence/absence was determined by examining the shoreline habitats to confirm the presence of larvae, pupae or adults under stones, rocks, sediment and/or submerged vegetation. Water body typology and macrohabitat were described following Hans & Reinhardt (2006). Each site visited was georeferenced using a Garmin 78SC GPS. Climatic variables (water temperature, air temperature, wind speed and relative humidity) were measured and, finally, samples collected of living individuals for research into phenology and physiology, and of individuals immediately preserved in alcohol (95%) for genetic studies. All samples were transported to the Wankara Laboratory at Magallanes University in Puerto Williams, Chile. Characteristics of the species according to the taxonomic key of Wirth & Gressitt (1967) were verified in the laboratory. The species was recorded in all locations surveyed except Diego Ramirez Island and the north-west coast of the Antarctic Peninsula. Survey data were combined with information from a careful bibliographic review.
| Etendue de l'étude | The area of study in Maritime Antarctica includes the South Shetland Islands and part of the north-west coast of the Antarctic Peninsula, both of which are included in Antarctic Conservation Biogeographic Region (ACBR) 3, North-west Antarctic Peninsula (for more information see Terauds et al., 2012; Terauds & Lee, 2016). In the Cape Horn Biosphere Reserve (Magallanes sub-Antarctic region, Rozzi et al., 2012), the study area includes the Navarino Island, the Cabo de Hornos National Park and the Diego Ramírez Marine Park. Records of the sub-Antarctic island of South Georgia are also included. During surveys the presence of any life stage of the species was recorded, macrohabitat was described, climatic variables recorded and a reference collection of individuals made. |
|---|---|
| Contrôle qualité | Each record of the species obtained in the field was georeferenced using a Garmin 78SC GPS. Most records obtained from literature included geographical coordinates. Where this was not the case, records were assigned a georeference by identification of the body of water described in the study. Geographic names used for records presented here are the official name used in the maps prepared by the SCAR Composite Gazetteer of Antarctica (CGA) and by the Military Geographical Institute (IGM) of Chile. For sites lacking formal names, ‘unofficial’ names were assigned. |
