4th ANdinA international workshop Species range extensions and local adaptation: challenging ecological and evolutionary ideas and assumptionsSan Carlos de Bariloche, Argentina, 29 January-2 February 2018ANdinA holds its unique dialogue-style workshops in wonderful locations around the world every two years. We bring together 30-40 researchers from a diverse range of disciplines to debate challenges, deconstruct contentious issues, develop new ideas and expand future horizons in topics related to ecology, evolution and management. We then publish the results of our deliberations and ideally walk away with the beginnings of new collaborations. This time we will be in the mountains of Patagonia discussing two distinct but inter-dependent topics: species range extensions and local adaptation. The meeting should therefore appeal to researchers interested in contexts such as responses to climate and other environmental change, species invasions, weed/pest management, conservation and adaptation to global change. The cost for everything (except travel to Patagonia and alcoholic beverages) is just US$1000. One third of places are reserved for Early-Career Researchers (who pay only US$400). Everyone will have the opportunity to co-author at least one paper to be submitted to an international journal. We are seeking expressions of interest from enthusiastic people who are prepared to actively involve themselves in relaxed, free-flowing dialogue. Come to challenge and to be challenged in a supportive, egalitarian environment. Contributions will be valued from any relevant area of research: molecular evolution to mathematical ecology, biophysical to social sciences, pure to applied, specialists to generalists.
