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.

Description:

Empowerment is a process by which an individual is endowed, community or social group of a toolkit to increase your strength, enhance your capabilities and enhance your potential, all this with the aim that you can improve your social situation, politics, economical, psychological or spiritual.

On the environmental issue, the Ministry of the Environment together with partners such as the EUROCLIMA + program, through the International and Ibero-American Foundation for Public Administration and Policies (FIIAPP), and the Inter-American Development Bank (BID), with the support of the React For Climate platform and the SIEF, Festival of Social Innovation in Chile, Action Meetings for Climate Empowerment have begun, that will allow the generation of inputs for the elaboration of the Strategy for Capacity Development and Climate Empowerment of Chile.

Action for Climate Empowerment -ACE for its acronym in English- is the agreed denomination for the article 6 of the United Nations Framework Convention on Climate Change, reflected in the article 12 of the Paris Agreement, and that contemplates six interdependent and interrelated dimensions: The education, the formation, public conscience, public participation, public access to information and international cooperation. ACE is a transversal proposal in public policies that seeks to generate and articulate capacities and commitments that promote action against climate change, with the depth and urgency that this challenge requires. It considers participation as one of its articulating dimensions.

Chile has an extensive coastline where socio-ecological systems converge that day by day are exposed to different forces among which Climate Change is one of them and which, added to overexploitation, present an uncertain future.

Therefore, What do we do from science? How do we spread the importance of ecosystems and their services? What media can provide us with more support in this flow of information to the coves?, towards the shore fishermen and gatherers?

The present symposium aims to share experiences, perspectives and challenges in the empowerment of artisanal fishermen on climate change, management of fishery resources and natural heritage, multiplying awareness, valuation and conservation of the southern territories of great biodiversity and culture, that under a systemic gaze, It has no political limits and therefore requires the active participation of all actors in these territories..

Description: Harmful Algal Blooms (FAN) o Red tides correspond to a proliferation in aquatic environments of microalgae that can cause the massive death of fish and other organisms, contaminating shellfish with toxins, and alter ecosystems, in ways that humans perceive them as harmful or harmful (GEOHAB, 2001). The impacts on Man and his activities, include shellfish poisoning, that can be fatal; massive deaths of marine organisms in the natural environment and in rearing or fattening systems; alterations of coastal habitats and, thus, disturbances in social and economic systems. In Chile, different toxins associated with Paralyzing Poison have been detected (VPM), Diarrheal Poison (VDM), and Amnesic Poison of Mollusks (TO YOU), which directly affect humans in addition to a number of other lipophilic toxins. Under this scenario, and considering the non-existence of antidotes for these toxins, the lack of technologies to control blooms in the environment or their removal from shellfish, the disturbances they cause in the social and economic systems, and the lack of models that allow predicting the appearance, duration and place of occurrence of these blooms, force to strengthen prevention and one of whose sources of information are monitoring programs.

The present symposium aims to share progress and experiences, views and challenges of the FAN problem among local researchers, with a view to updating the status of the studies developed at the national level, discuss new approaches and look for questions and common points for future global change scenarios, in which these events are expected to increase their frequency to intensity at the local and global level.
