The Complex Genetic Legacy of Hybridization and Introgression between the Rare ...
Draper, David; Riofrío, Lorena; Naranjo, Carlos; Marques, IsabelHybridization and introgression are complex evolutionary mechanisms that can increase species diversity and lead to speciation, but may also lead to species extinction. In this study, we tested the presence and genetic consequences of hybridization between the rare and Ecuadorian endemic O. loxensis van der Werff and the widespread O. infrafoveolata van der Werff (Lauraceae). Phenotypically, some trees are diff...
Genetic diversity and structure in two epiphytic orchids from the montane fores...
Riofrío, María; Naranjo, Carlos; Mendoza, Alberto; Draper, David; Marques, IsabelEcuador has a high diversity of orchids, but little is known about levels of genetic diversity for the great majority of species. Understanding how orchids might adapt to changes is crucial as deforestation and fragmentation of forest ecosystems threaten the survival of many epiphytic orchids that depend on other species, such as fungi and their host trees, for germination, growth, and establishment. Overcollec...

Early Signs of the Effects of Forest Fragmentation on the Genetic Diversity and...
Marques, Isabel; Draper, David; Riofrío, Lorena; Naranjo, CarlosThe diversity of genetic resources is essential to cope with environmental changes. However, despite forests play a crucial role in mitigating changes, genetic knowledge has scarcely been used for forest conservation. In this study, we used nuclear microsatellites to understand the patterns of genetic diversity and population genetic structure in Ocotea rotundata van der Werff (Lauraceae), an endemic Ecuadorian...
