GENETIC VARIABILITY OF MATE DUE TO GEOGRAPHIC ANDENVIRONMENTAL CONDITIONSAnanda Virginia de Aguiar1;  Marcos Silveira Wrege1; Valderês Aparecida de Sousa1;Márcia Toffani Simão Soares1; Elenice Fritzsons1; Itamar Antônio Bognola1; AndressaGodinho Scarante2, Victoria Mariá Souza Marcondes21Embrapa Florestas.

St. Hill.) is a native species in Southern, Southeastern and MatoGrosso do Sul State of Brazil, Paraguay and Northwestern region of Argentina. Mate iswidely consumed as a tea and it is produced by extraction of dried leaves. Recently, newuses have been discovered for the pharmaceutical and cosmetics industries. It isrepresentative species of temporal region, frequently living in high altitudes. Nowadays, Mateis considered an endangered species. The original Mate forest (Araucaria Forest) had lost97% of its area. This caused the further loss of genotypes and genetic variability. Despite theloss of large areas of Araucaria Forest and its genotypes, there are many populations withvarious characteristics present in multiple environments. This occurs due to long term ofadaptation to many factors, such as variations in relief, climate and soils in very shortdistances. Mate has high productivity and genetic gain potential. Thus, we propose toestimate genetic diversity of these populations related to geographical characteristics byconsidering to limit conditions climate and soil. Based on the knowledge acquired, we will beable to determine the natural range, or ecological niche, of the more relevant populations. Itwill also enable us to identify tendencies of these populations to move up due to climatechanges. In this way, we will be possible to suggest conservation strategies for the species.Keywords: genetic conservation; climate change; ecological niche.Acknowledgements:Embrapa Florestas by project resources 'Distribution of natural occurring populations ofAraucaria and Mate for breeding and conservation programs' (Distribuição de ocorrêncianatural de populações de araucária e erva-mate para uso em programa de conservaçãogenética).
