En la presente tesis desarrollo una cronología de cambios en la vegetación y paleofuegos que abarca los últimos 17.000 años a partir de testigos de sedimentos lacustres obtenido de Laguna Churrasco (45°41’S, 71°49’O, 798 msnm), región de Aysén. El objetivo es documentar la historia de la vegetaci...

In this thesis I present a record of changes in vegetation and paleofires over the last 17,000 years from sediment cores obtained from Laguna Churrasco (45 ° 41'S, 71 ° 49'W, 798 masl), Aysén region. The objective is to document the history of vegetation and paleofires, their reciprocal relations...

Viruses are ubiquitous in all environments and hot-springs are not the exception even though its extreme conditions. Phototrophic mats of terrestrial hot-springs have been used for decades as models for understanding the composition, structure, and function of microbial communities in nature. The...

Los virus son ubicuos en todos los entornos y las fuentes termales no son la excepción a pesar de sus condiciones extremas. Los tapetes fototróficoss de las fuentes termales terrestres se han utilizado durante décadas como modelos para comprender la composición, estructura y función de las comuni...

Discarding Antarctic and sub Antarctic regions, the Andes concentrate almost 90% of glacier cover in the Southern Hemisphere. Large data gaps exist here, preventing detailed knowledge on how climate determines glacier behavior. As Andean glaciers are distributed in a latitudinal transect spanning...
