Las plantas introducidas constituyen una de las amenazas más grandes que enfrenta la biodiversidad natural de Galápagos. Desde el primer momento en que la gente colonizó el Archipiélago, las personas han introducido plantas y animales intencionalmente para alimento, medicina, madera también como mascotas y para ornamento; además algunas especies han sido introducidas accidentalmente. De las aproximadamente 850 especies de plantas introducidas que están presentes en Galápagos, cerca del 60% son ornamentales. Algunas de éstas ya han escapado de los jardines y se han convertido en un problema, otras están esperando para hacerlo. Muchas de las especies de plantas nativas de Galápagos son atractivas y muy adecuadas para ser parte de un jardín ornamental; sin embargo se usan raramente porque son desconocidas por la gente. Una medida positiva y proactiva para ayudar a la protección de Galápagos de futuros problemas es incentivar a la gente a plantar especies nativas en sus jardines en luga...

Calandrinia galapagosa (Portulacaceae), is a critically endangered endemic plant from San Cristóbal Island, Galapagos. The species is threatened by goat herbivory and less than 1300 individuals remain, in nine populations. Three of these populations have been fenced to protect them from herbivory. However is not known whether these three populations are representative of the species. In addition, the species also shows 3 distinct color morphs and there has been speculation that these may represent different taxonomic units. This study uses AFLP markers to determine the genetic structure of the species, both by population, and by color morph. All nine populations were analyzed with a total of 189 specimens representing three different phenotypes. The analysis, based on 113 polymorphic AFLP markers, revealed low differentiation within populations and across phenotypes, and no correlation of geographic and genetic distance. These results indicate regular gene flow between populations a...
