2012/feb |

The last week of February was intense and very helpful in the company of Dr. Jurgen Laudien and his colleagues, including David Bellhoff, assistant at the Huinay Foundation.
After six days of intense diving, the objectives were met and the whole team was more than satisfied. Were placed in total thirty recruitment tiles in the vicinity of the Reserve, in order to study the colonization of benthic fauna in the medium and long term. Añihue Reserve will be responsible for collecting data and taking pictures underwater to demonstrate the order of colonization of individuals.
As part of a parallel investigation, fifteen individuals of the species of coral Desmophyllum dianthus were marked with techniques that allow studying its growth rings per year by 2014.
Fifty shells of the ancient brachiopod Magellania venosa were marked to analyze their growth to 2013. This analysis will help researchers find the reasons why these shells abound and have developed so well on the Chilean coast, unlike the rest of the world where there are almost no examples. In turn, thirty samples of this specie were collected (preserved in 100% ethanol), which were taken to Germany to study their genetic structure.
Also collected and taken to Germany were twenty samples of shrimp species Munida gregaria for taxonomic identification and comparison with other samples of Chilean Patagonia and the Falklands. This species is an important part of the marine benthic community in Patagonia, occupying a key position in food webs of coastal fish, birds and marine mammals. The aim of this study is to obtain information on the genetic structure and population.
The data obtained in each study will be compared with those analyzed in the Comau Fjord, near the Huinay Foundation.
