The interaction between metazooplankton metabolism and the microbial loop is recognized as one of the principal mechanisms controlling the quantity, composition and cycling of DOM in the sea. Zooplankton and bacteria are usually considered as separate groups despite their temporal and spatial co-...
La interacción entre el metabolismo del metazooplancton y el anillo microbiano es considerado uno de los principales mecanismos que controla la cantidad, composición y el reciclaje de la materia orgánica disuelta en el océano. Zooplancton y microorganismos suelen considerarse como grupos separado...
La implementación de la educación ambiental ha sido impulsada a nivel de gobierno a través de numerosas políticas públicas. Sin embargo diversos estudios evidencian que en la práctica las iniciativas a nivel local no se traducen en cambios de conductas ciudadanas a favor del medio ambiente.

In the case of tsunamis generated by large subduction earthquakes (which is the case in
Chile), they can cause hundreds or thousands of fatalities, to devastate coastal infrastructure,
and to damage the national economy. Therefore, it is highly important to know the
tsunami hazard in a given regi...
En el caso de tsunamis generados por grandes terremotos de subducción, como es el
principal caso chileno, éstos pueden arrasar con cientos o miles de vidas de personas,
así como también causar una gran destrucción en infraestructura portuaria, afectando
considerablemente la economía del país. Es ...
La enzima convertidora de Endotelina-1c (ECE-1c) es una metaloproteasa de zinc y participa en la síntesis de ET-1 (ET-1). En diversos tipos de cáncer, ET-1 promueve propiedades mitogénicas, promoviendo proliferación e invasión celular. Adicionalmente, ECE-1c se ha descrito como un mediador de la ...
Endothelin-Converting Enzyme-1c (ECE-1c) is a membrane Zn-metalloprotease that synthesizes Endothelin-1 (ET-1). In many cancers, ET-1 has mitogenic properties, promoting proliferation and invasion. In addition, ECE-1c has been observed as a mediator of cancer invasiveness, however, whether this p...
Obliquely convergent subduction margins develop trench-parallel faults shaping the regional architecture of orogenic belts and partitioning interplate deformation. However, transverse faults also are common along most orogenic belts, although have been la
The aim of this Ph.D. thesis is to have a better comprehension of the interactions between coupling, slow slip events (SSEs) and the seismic ruptures in subduction zones. This work focuses on the North Chile - South Peru subduction zone that has been recognized as a mature seismic gap. Thus, the ...
Las cuencas de rift son lugares altamente dinámicos, donde se conjugan el
fallamiento activo, el magmatismo, y la sedimentación, representando un contexto
ideal para la preservación del registro geológico. Por otro lado, la reactivación de sus
estructuras ejerce un control sustancial en la constr...
The Southern Andes Volcanic Zone (SVZ) is located in the main Cordillera of the Andean region in southern Chile. The volcanic zone is located between 33°S and 46°S and consists of a variety of magmatic features, in particular sheeted dyke intrusions. Thes
This thesis addresses the eco-hydrological cycles of forests and the complex relationship between them and social systems, in the context of the dynamics of temperate forests in southern Chile. The text is structured in three chapters: the first and the second seek to understand the changes of a ...
Esta tesis aborda los ciclos eco-hidrológicos de los bosques y la compleja relación con los
sistemas sociales, en el contexto de la dinámica de los bosques templados del sur de Chile. El
texto se estructura en tres capítulos: el primero y el segundo buscan entender los cambios de
un bosque templa...
The strong ground motions generated by earthquakes can be related to the characteristics of the earthquakes source (stress drop, rupture velocity etc..), and therefore to the frictional conditions of the faults. These characteristics are usually studied by analyzing the low frequency band (≤ 1Hz)...
