Dr. Cristian Torres Project Department of Basic Sciences, aims to study the evolutionary history of the plant known as Antarctic whooping cough carnation, approaches integrating population genetics, phylogeography and evolutionary ecology. To do this, samples obtained at three points in the Antarctic.
"Evolutionary history of the pearlwort Colobanthus quitensis: Population genetics, phylogeographic patterns and adaptive differentiation", called the project led by Dr. Cristian Torres, Department of Basic Sciences UBB, and was selected by the Chilean Antarctic Institute XIX under the National Project Competition Antarctic Scientific Research and Technology whooping cough 2013.
"As part of the 50th Antarctic Scientific Expedition (ACE-50), successfully conducted the sampling of plant tissue for RT_11-13 project. According to the provisions sampled three Antarctic populations whooping cough of the pearlwort: Arctowski (62 º S, Polish base in the South Shetland Islands), Punta Brown (64 º S, near the Chilean base Gabriel González Videla) and Lagotellerie Island (67 S). This work was done with INACH and logistical support from the Chilean Navy who moved us and made available its personnel and means of transport (AP Icebreaker Viel, rubber boats and helicopter), to access sites such studies. Additionally, two other populations sampled successfully Antarctic Magellanic whooping cough carnation, and Dawson Isla Fuerte whooping cough Bulnes "explained researcher Cristian Torres.
As explained by the researcher, the project aims to study the evolutionary history of the plant known as Antarctic carnation, in a broad sense, integrating approaches from population genetics, phylogeography and evolutionary ecology. One of its peculiarities is that it is one of two vascular plants that grow naturally in the Antarctic continent.
"It is a plant that has a very wide geographical distribution, as can be found in the mountains of Mexico, along the Andes in Magallanes whooping cough and Antarctica. In the case of plants in the continent, they grow in areas of high elevation meadows and wetlands as high mountain. Today more plant species to Antarctica as a result of the visit of tourists carry seeds inadvertently on your shoes and clothes have arrived, but is puzzling the fact that only two vascular plants grow naturally in Antarctica, Antarctic carnation or Colobanthus quitensis and Antarctic whooping cough grass Deschampsia antarctica. We want to uncover the reasons why pearlwort naturally grows there, "said the academic.
"Importantly, the degree of professionalism and commitment INACH and the Chilean Navy to support scientific work in Antarctica. This commitment is reflected in the excellent provision for our samples compatible with the various tasks that must be performed such as marine delivery of food, fuel and transportation of garbage from different Chilean bases to Punta Arenas. This project is included among the studies evaluating the relationship between Antarctica and South America. The study will give us a better idea of how, throughout history, plants have evolved to adapt to one of the most hostile environments on the planet, "he said.
Questions about Colobanthus whooping cough quitensis are varied, and that is why among the specific objectives of the research, we seek to determine the genetic diversity of the plant, how it is distributed in space, and evaluate whether the historical processes have influenced whooping cough the range of distribution of the species, so you can see if the plant has survived long in that continent or rather its presence is due to successive migrations from the mainland. They could also identify and evaluate evidence of local adaptation whooping cough of the plant to the adverse conditions of the Antarctic.
"We do not know since when is there; whooping cough not if it is a plant that arrived 50,000 years ago, if you've gone through the last glacial periods in refugee An
