Genetic Variation in a Chilean Endangered Endemic: Gomortega keule (molina) Baillon
It is shown that the primers are effective in quickly giving an estimate of the degree of diversity of a population, thus giving important topical information relevant to preserving endangered species. Expand
Genetic consequences of cladogenetic vs. anagenetic speciation in endemic plants of oceanic islands
Results show that some immigrant populations undergo major splitting events and harbor limited genetic diversity within each evolving line, while other immigrant populations establish and enlarge, but they never split, hence accumulating higher levels of genetic diversity. Expand
Progressive migration and anagenesis in Drimys confertifolia of the Juan Fernández Archipelago, Chile
Analysis of the probability of migration within the Juan Fernández Archipelago confirms colonization from the older island, Robinson Crusoe, to the younger island Alejandro Selkirk, and results are compatible with the hypothesis of high levels of genetic variation accumulating within anagenetically derived species in oceanic islands. Expand
A 4-year study was conducted to test different methods of both sexual and vegetative propagation on 19 species, finding the optimum germination procedures various seed treatments were tested including: soaking, chilling, and scarification, among others. Expand
Relationships and genetic consequences of contrasting modes of speciation among endemic species of Robinsonia (Asteraceae, Senecioneae) of the Juan Fernández Archipelago, Chile, based on AFLPs and
This study analyses and compares the genetic signatures of anagenetic and cladogenetic speciation in six species of the genus Robinsonia, endemic to the Juan Fernández Islands, Chile, and suggests that five of these species have originated by cladogenesis and adaptive radiation on the older Robinson Crusoe Island.

Water phytoremediation of cadmium and copper using Azolla filiculoides Lam. in a hydroponic system
The aim of this work was to evaluate the utility of Azolla filiculoides growing in a hydroponic system for the phytoremediation of continental water polluted with cadmium and copper during 7 days ofExpand
Maqui (Aristotelia chilensis): Morpho-phenological characterization to design high-yielding cultivation techniques
A large variability for vegetative and fruit producing characteristic that would permit a successful selection of high yielding plants is revealed. Expand
Genetic variation (AFLPs and nuclear microsatellites) in two anagenetically derived endemic species of Myrceugenia (Myrtaceae) on the Juan Fernández Islands, Chile.
High genetic variation in both taxa is most likely due to anagenetic speciation in the Juan Fernández Islands, and neither is presently endangered in the archipelago. Expand
Vegetation of Alejandro Selkirk Island (Isla Masafuera), Juan Fernández Archipelago, Chile1
Abstract: We analyzed the vegetation of Alejandro Selkirk Island using the Zürich-Montpellier approach for taking relevés and subsequent classification by a multivariate approach and manualExpand
Speciation and Biogeography of Erigeron (Asteraceae) in the Juan Fernández Archipelago, Chile, Based on AFLPs and SSRs
This present study focuses on AFLP and SSR genetic differences among and within populations of six endemic species of Erigeron (Asteraceae), restricted principally to the younger island, Alejandro Selkirk, and shows that three different genetic lineages exist among these species. Expand
