International Symposium “Recent Research on Magellan-Antarctic Connections” Punta Arenas, 28th and 29th May 2020
The International Symposium “Magellan-Antarctic Connections” will be held during the week of the 40th National Marine Chilean Science Conference on the 28th and 29th of May, 2020. Both events will take place at the University of Magallanes, Punta Arenas, Chile. The main purpose of this symposium is to provide insight into recent and current ecologic, evolutionary, biogeographic, geologic, and oceanographic research in the Magellan region and its connections with the Antarctic. This meeting will be joined by scientists with the common goal to enhance the development of Magellan and Antarctic research and to facilitate the exchange of scientific information in a framework of international collaboration.
Content, concept, and scientific significance
The Magellan region is a highly vulnerable and complex ecosystem, which will be severely affected by climate change due to its proximity and close connection with the Antarctic. It offers a unique natural laboratory that demands increasing research in the near future. In the last years, the need for sub-Antarctic and Antarctic research has increased, and as a consequence, much research effort has to be oriented towards the study of ecologic, evolutionary, geologic and oceanographic processes and how they are connected. Novel information, training of young scientists and cooperative projects should provide improved facilities to study and understand those processes that give rise to the similarities and differences between the austral-polar biotas and their extreme environments. Thus, the symposium offers a scientific platform for presenting and discussing some of the latest advances in research that focuses on life and environmental sciences in high latitude marine systems.
Principal objectives to achieve:
– To fill gaps in scientific knowledge about the state of sub-Antarctic and Antarctic marine ecosystems.
– To provide basic information on the main factors that may impact sub-Antarctic and Antarctic marine systems.
– To stimulate possible joint research projects, to enhance future scientific polar and subpolar knowledge through national and international collaboration.
This meeting has the aim of preparing a third IBMANT symposium (IBMANT III), as a follow-up of the two conferences held in Punta Arenas (1997) and Ushuaia (2003), in two years’ time.
The symposium will be divided in three major sections:
Understanding key ocean-atmosphere-ice interactions in sub-Antarctic and Antarctic ecosystems.
Coordinator: José Luis Iriarte (IDEAL, Austral University of Chile)
Environmental and ecological vulnerabilities were important criteria in the decision to choose research in sub-Antarctic and Antarctic coastal systems, given their sensitivity to climate changes in complex coastal zones that are undergoing increasing human development and impact. Examples are the development of natural perturbations (harmful algae blooms), global climate change and regional anthropogenic activities such as tourism, induced large variability in shellfish stocks and potential massive aquaculture arrival, among other activities. This section will put particular emphasis on integrating studies, such as (1) how ocean chemistry and physical structures respond to climatic forcing and may affect the biological processes and community/trophic structure on different spatial/temporal scales, (2) the role of key functional species such as whales and krill populations, (3) how global problems pertaining to oceanography and global change related to glacial melting and change of the input of freshwater to the coastal ocean, (4) how actual interactions of environmental stressors such as temperature, acidification, and salinity affect biological performance of microbial assemblages such as HAB.
Sub-Antarctic and Antarctic advances in marine biological research: Gaps and challenges in benthic ecology from individuals to ecosystems.
Coordinator: Claudia Andrade (Institute of Patagonia, University of Magallanes)
Sub-Antarctic and Antarctic ecosystems are experiencing significant ecological and environmental change. Benthic studies have been concentrated on a relatively small number of sites, and the ecology of those communities has shown well-defined patterns dominated by suspension feeders, playing an important role in the organic carbon flow. In this symposium, we will focus on spatiotemporal patterns of benthic communities considering multi-approaches in the field of ecology, physiology and genetics. The main task will consider to evaluate (1) the legacy of the Last Glacial cycles over spatial patterns of genetic diversity and genetic connectivity between Antarctic and South American populations, (2) how sub-Antarctic and Antarctic benthic communities are shaped in terms of trophic structure, and (3) the impact of environmental factors on benthic communities, productivity, distribution, and ecosystem functioning.
Paleoceanographic and geological studies on sub-Antarctic and Antarctic systems, gaps and challenges for the next years.
Coordinator: Lorena Rebolledo (Chilean Antarctic Institute).
The main goal of this section is to present paleoceanographic, and geological studies in the sub-Antarctic and Antarctic regions, emphasizing the gaps, challenges for improved studies, collaboration between countries and researchers. This section will focus on the key questions of connections between sub-Antarctic and Antarctic regions, and the evolution of the Antarctic Circumpolar Current (ACC) during the Last Glacial Maximum with special reference to evidence in the Magellan region.

Antarctic Biodiversity Genomics Symposium
Genomic data input to the Antarctic and Sub-Antarctic biodiversity in a context of climate change
Symposium of Genomics Antarctic Biodiversity
Genomic insight into Antarctic and Subantarctic biodiversity in a context of climate change
Description: The Antarctic continent is one of the most pristine and isolated bathymetry, climate and oceanographic and geographic barriers resulting from tectonic and climatic events that began in the Eocene. Antarctic and subantartic biota has evolved to adapt to extreme living conditions and is characterized by a high degree of endemicity. Nevertheless, the recent acceleration of climate change and anthropogenic pressures can definitely affect biodiversity Antarctica. Nevertheless, the recent acceleration of global warming increases the chances of disrupting the fragile Antarctic ecosystems and can definitely affect biodiversity Antarctic, particularly through the invasion of alien species and the loss of native biodiversity. The West Antarctic Peninsula has been described as one of the areas most affected by climate change, Thus, They have increased the potential to disrupt this fragile ecosystem. Understanding how the Antarctic biodiversity responded to past changes, It will help us to predict the fate of the Antarctic biota against anthropogenic climate change.
The recent and rapid spread of genomics-based techniques has increased in ecological and evolutionary science our ability to explore and understand historical and contemporary effects of climate change on diversification, and demographic history of Antarctic biodiversity adaptation (microorganisms including, plants, invertebrate and vertebrate species). This information will allow to understand the response and resistance of Antarctica and subantarctic biota during events and climate change, Thus, predict the fate of a single biogeographic province facing the challenges of the Anthropocene.
goals: Studies show this symposium dedicated to understanding the historical and contemporary effects of climate change on diversification, demographic history, and adaptation of Antarctic biodiversity based on genomic data. This symposium will present studies on the historical and contemporaneous effects of climate change on the diversification, demography and adaptation of the Antarctic biodiversity based on genomic data.

descriptionfromn
The sea and its resources have been used extensively over thousands of years in different regions of the world play a key role in subsistence and social and cultural construction of human groups. In this interaction, human behavior and adaptive responses, They have been transformed in accordance with the paleoecological and environmental dynamics of the past.
The South American coast in particular has seen this human interaction in marine ecosystems since the late Pleistocene, a marked intensification of these dynamics from mid Holocene, generating significant changes in both the natural and cultural environment.
In this symposium we invite you to integrate different lines of research on the relationship between cultures and the sea through prehistory and history. We propose an instance to present different perspectives on the role of human groups in coastal ecosystems in South America and vice versa, the role of coastal ecosystems in the historical development of coastal societies.
Some of the topics we propose:
- underwater archeology
- Archeology intertidal
- Archeology and history of coastal settlements
- paleoecological or environmental reconstruction and coastal societies (isotopic Ecology, sclerochronology)
- Subsistence and coastal zooarchaeology
- Navigation technology and exploitation of marine resources in prehistory and history
- adaptations island
