===== Bryophyte Flora and Vegetation in Mediterranean areas ===== Especially in areas of southern Spain and northern Africa. ===== Molecular Systematics and Phylogeny in Bryophytes ===== Studing some groups of mosses as Pottiaceae, Grimmiaceae, Leucodontaceae ===== Phylogeography of Bryophytes ===== Origin and diversification of bryophytes considered endemic to Canary Islands. ===== Conservation of endangered species ===== The most important objective in this area is to make “Red Lists” and ex-situ conservation of bryophytes, by performing in-vitro culture and cryopreservation. ===== Climate Change ===== Mosses are excellent model organisms to study climate change effects on plants. Research is being conducted in Sierra Nevada Mountains (southern Iberian Peninsula) and Teide (Tenerife, Canary islands), using cosmopolitan species as //Bryum argenteum, Ceratodon purpureus// and //Funaria hygrometrica//. ===== Population Genetic ===== We have performed population genetic studies in cosmopolitan mosses and in threatened vascular plants such as //Astragalus nitidiflorus// para el Proyecto LIFE Garbancillo de Tallante[[http://www.lifegarbancillo.es/]], //Cistus heterophyllus// var.// carthaginensis// y //Echium acanthocarpum// ===== Evolutionary Biology ===== To have a better understanding of the biology and evolutionary ecology of bryophytes, the group has carried out studies of the genome and epigenome, as well as the environmental niche and the interactions between biotic and abiotic drivers of biodiversity. He has used the species //Ceratodon purpureus//, a model organism, and its sister species //C. amazonum// as study subjects.
