Línea 3: Fisiología del cambio global

DESCRIPCIÓN:

Mis intereses de investigación abarcan una amplia gama de temas, pero en su mayoría, dedicados a la fisiología ecológica con fuertes lazos en la ecología del comportamiento, ecología evolutiva y la biogeografía. En mi opinión, la comprensión de los procesos ecológicos y patrones evolutivos globales subyacentes sólo puede lograrse mediante una integración de estas disciplinas. El estudio de los mecanismos, los rendimientos y las tolerancias fisiológicas, contribuyen, según el taxón y la escala de estudio, a explicar la distribución, la abundancia y el éxito evolutivo de las especies y poblaciones endémicas, como introducidas (pestes, vectores de enfermedades) y de valor comercial (cultivos). En mi opinión, este esfuerzo se está convirtiendo cada vez más importante debido al ritmo acelerado de las perturbaciones ambientales inducidos por el hombre.

OBJETIVOS:

  • Estudiar las respuestas fisiológicas, ecológicas y evolutivas al  cambio global
  • Integrar aspectos de fisiología con manejode la biodiversidad
  • Utilizar nuevas herramientas experimentales (genómica, biología molecular, toxicología) y teóricas (modelos matemáticos) para entender y predecir el impacto de  los cambios ambientales sobre la biodiversidad.

PROYECCIONES:

Entregar explicaciones y transferir a la sociedad conocimiento y propuestas sobre los impactos y respuestas de los organismos nativos, introducidos y pestes a los cambios ambientales rápidos.

Research:

My research interests cover a broad range of topics, but I am mostly engaged in ecological physiology with strong ties into behavioral ecology, evolutionary ecology and biogeography. In my opinion, an understanding of the processes underlying global ecological and evolutionary patterns can only be achieved by an integration of these disciplines. Hence, physiological mechanisms and tolerances, ecological and evolutionary constraints all contribute, depending on the taxon and scale of study, to the distribution, abundance and success of species and populations. I have long studied the impact of environmental changes on intergative physiology, with the primary goal of determining and assessing the proximate abiotic and biotic factors that might impact the Darwinian fitness. In my opinion, this endeavor is becoming increasingly important due to the accelerating rate of human-induced environmental perturbations.

Objectives:

Study organismic responses to the impact of global change

Integrate aspects of physiology biodiversity management

Use new tools (genomics , molecular biology , toxicology ) to understand and predict the impact of environmental change on biodiversity

Actual research lines:

We investigate (eg, metabolic, thermoregulation, digestive, osmotic, immunological, neuronal) physiological limitations on biodiversity, in order to improve the ability to predict responses of organisms to environmental perturbations, such as climate change, disease and habitat loss. In our opinion, by understanding the underlying mechanistic basis of the capabilities of the body to respond to biotic and abiotic environment, a solid foundation can be built to develop predictions about the likelihood of success or failure of individuals, populations and species (including invasive species and crops or human beings) to deal with the global changes that are coming. As integrative biologist, working with invertebrates (eg piriwinkles, mussels, insects and woodlices) and vertebrates (eg fish, amphibians, lizards, birds and mammals).

Projections and challenges:

Deliver explanations and transfer knowledge to society and proposals on the impacts and responses of organisms to environmental changes

Línea 2: Aproximaciones de la bioingeniería a la protección del medio ambiente y las tecnologías sustentables.

DESCRIPCIÓN:

Los microorganismos son un componente biológico esencial en el funcionamiento de nuestro planeta. Aunque todavía hay un gran nivel de desconocimiento sobre tipos, características y procesos microbianos, lo que hoy si se sabe es que hay un tremendo potencial en los microorganismos conducente a mejorar la productividad, innovar y proteger el ambiente. Es en la aplicación efectiva de este potencial, entre otras iniciativas, donde el “Center of Applied Ecology and Sustainability” (CAPES) focaliza tanto la generación y transferencia de conocimiento original, como la formación de capital humano avanzado, con miras a permitir el desarrollo sustentable en Chile. Ejemplos de esto son las actividades de investigación y transferencia tecnológica que desarrollamos en áreas como el diseño de agroquímicos o agentes biocidas basados en microorganismos benéficos; la aplicación de estrategias de bio y fitorremediación para la limpieza de ambientes contaminados con derivados del petróleo, residuos mineros u otros contaminantes; o el monitoreo y control de la actividad de microorganismos que producen efectos indeseables como el drenaje ácido de minas, o la biocorrosión; además de estudiar la producción microbiana de materiales como celulosa y calcita. Para ello se utilizan aproximaciones tradicionales y modernas como la Biología Sintética, la (meta)Transcriptómica, la Minería de Datos y la Bioinformática, entre otras.

OBJETIVOS:

  • Uso de enfoques de última generación para el estudio de procesos microbianos de relevancia ambiental (secuenciación masiva; (meta)transcriptómica y (meta)genómica; herramientas computacionales de alta capacidad para minería de datos, modelamiento y predicción)
  • Contribución a la investigación fundamental en aspectos que, inexplicablemente, han recibido menos atención (mecanismos de promoción microbiana del crecimiento de plantas en condiciones normales y estresantes; respuestas moleculares y fisiológicas de plantas a microorganismos; mecanismos de control del crecimiento de biopelículas; bases para evaluar efectividad de estrategias de bio(fito)remediación, geomicrobiología de drenajes ácidos mineros, entre otros).
  • Integración de investigadores en Ingeniería y Computación para facilitar la resolución de problemas reales en donde estén involucrados procesos microbianos, a través de la adquisición, preprocesamiento, modelamiento y análisis de los datos generados en el laboratorio.
  • Difusión de la relevancia de las funciones microbianas en múltiples aspectos tecnológicos y ambientales, y los aspectos fundamentales y aplicados de las investigaciones realizadas a distintos actores de la sociedad.
  • Establecimiento de interacciones sinérgicas con las otras líneas CAPES que abordan problemas relevantes en Ecofisiología, Ecotoxicología, Manejo Ambiental, Ecología de Poblaciones, entre otras, que tengan un componente microbiano que considerar en su resolución o estudio.

PROYECCIONES:

  • Contribuir a la resolución efectiva de problemas ambientales en Chile.
  • Desarrollar productos agroquímicos que reduzcan el impacto ambiental de la agricultura, que permitan el uso de suelos no cultivables y/o que mejoren la productividad de la industria.
  • Generar conocimiento científico de alto impacto en las áreas fundamentales de Microbiología Ambiental y Biología Vegetal, y con aplicaciones concretas en actividades relevantes a nivel nacional, como la agricultura, minería, tratamiento de residuos, etc.
  • Incorporar modelamiento matemático y simulaciones computacionales para estudiar problemas ambientales como también ver el efecto que podrían tener las soluciones propuestas.
  • Formar nuevos científicos con capacidad para aplicar conocimientos básicos de la Microbiología, Biología Vegetal y Biotecnología Ambiental, entre otras, a la solución de problemas reales.

Research:

Microorganisms are an essential biological component in the functioning of our planet. Although there is still a great deal of ignorance about types, characteristics and microbial processes, which if known today is that there is tremendous potential in microorganisms conducive to improving productivity, innovation and protect the environment. It is in the effective implementation of this potential, among other initiatives, where the «Center of Applied Ecology and Sustainability» (CAPES) focuses on both the generation and transfer of original knowledge, the formation of advanced human capital in order to allow development sustainable in Chile. Examples of this are the research and develop technology transfer in areas such as design of agrochemicals or biocides based on beneficial microorganisms; the application of bio strategies and phytoremediation to clean petroleum-contaminated environments, mining waste or other pollutants; or monitoring and control of the activity of microorganisms that produce undesirable effects such as acid mine drainage, biocorrosion or biofouling; in addition to studying the microbial production of materials such as cellulose and calcite. For this traditional and modern approaches such as synthetic biology, the (meta) transcriptomics, data mining and bioinformatics, among others are used.

Objectives:

1) Using last generation approaches to the study of microbial processes of environmental relevance (massive sequencing, (meta) transcriptomics and (meta) genomics, computational tools of high capacity data mining, modeling and prediction).

2) Contribute to fundamental research in areas that have inexplicably received less attention (microbial mechanisms promoting plant growth under normal and stressful conditions; molecular and physiological responses of plants to microorganisms, mechanisms of biofilm growth monitoring; bases that evaluate effectiveness of strategies in bio (phyto) remediation geomicrobiology acid mine drainage, etc.).

3) Integrate Engineering and Computer Science researchers to facilitate the resolution of real problems where they are involved microbial processes through the acquisition, preprocessing, modeling and analysis of the data generated in the laboratory.

4) Dissemination of the importance of microbial functions in multiple technological and environmental aspects, and fundamental and applied research conducted at different actors in society issues.

5) Establishment of synergistic interactions with other CAPES lines that address relevant problems in ecophysiology, Ecotoxicology, Environmental Management, Ecology of Populations, among others, which have a microbial component to consider in its resolution or study.

Actual research lines:

1) Study the microbial molecular mechanisms involved inplant growth promotion.

2) Characterize the molecular and physiological responses involved in plant responses to microorganisms in normal growth conditions or stress.

3) Study the factors involved in chemical signaling between plants and microorganisms.

4) Evaluate bio strategies involved in (phyto) remediation of petroleum contaminated sites, chloroaromatic pesticides or metals.

5) Evaluate microbial component in the potential for acid mine drainage.

6) Develop algorithms to construct gene regulatory networks using gene expression data.

7) Study robustness of biological networks through neutral space.

8) Study microbial strategies involved in the production of cellulose and precipitation of calcite, regulation and metabolic requirements.

Projections and challenges:

1) Design of genetic circuits using synthetic biology tools for the development of growth-promoting agents, screening tools, and / or academic teaching of molecular genetic resources.

2) Contribute to the effective resolution of environmental problems in Chile.

3) Develop agricultural chemicals that reduce the environmental impact of agriculture, which does not allow the use of arable land and / or improve the productivity of the industry.

4) Generate high impact scientific knowledge in the fundamental areas of Environmental Microbiology and Plant Biology, and with specific applications in relevant activities at the national level, such as agriculture, mining, waste treatment, etc.

5) Incorporate mathematical modeling and computer simulations to study environmental problems as well as see the effect they could have proposed solutions.

6) Train new scientists with ability to apply basic knowledge of Microbiology, Plant Biology and Environmental Biotechnology, among others, to solve real problems.

7) Establish genuine links between different actors (companies, government, NGOs, etc.) that allow efficiently translate research carried out in our laboratories in environmentally sustainable development strategies.

Línea 1: Enriquecimiento del ambiente por metales: de los efectos a los remedios

DESCRIPCIÓN:

La industria minera se relaciona de distintas formas con el medio ambiente. Algunas de estas interacciones han sido sobre-focalizadas, particularmente las percibidas por la sociedad como “negativas”; otras interacciones con posibles efectos neutros o positivos han sido, por otro lado, sub-consideradas o subvaloradas no sólo por la sociedad sino también por el propio sector minero. Adicionalmente, existe un extenso debate entre los actores involucrados (reguladores, empresarios, comunidades e investigadores, entre otros) sobre la factibilidad de realizar minería en forma sustentable. En esta línea de investigación del CAPES aportaremos antecedentes que permitan objetivizar los efectos de las interacciones del sector minero con el medio ambiente, con énfasis en el enriquecimiento con metales de distintas matrices ambientales (suelos, aguas superficiales y marinas), y determinar cuan sustentable es este sector productivo ante distintos escenarios productivos. Por ejemplo, se abordarán aspectos relacionados con la evaluación de riesgo ecológico de los enriquecimientos con metales (biodisponibilidad, toxicidad para los organismos y movilidad ambiental), aportando con herramientas metodológicas apropiadas para la identificación de riesgos. Se desarrollarán distintas alternativas de rehabilitación ecológica para sitios perturbados por la industria minera, basadas en la reconstrucción de ecosistemas autosustentables. Todos estos conocimientos, herramientas y enfoques serán transferidos a la industria minera, los reguladores y a la sociedad en general, de forma de posibilitar el desarrollo sustentable del sector minero. Adicionalmente, se propenderá a la formación de capital humano especializado en estas líneas de trabajo.

OBJETIVOS:

  • Objetivizar los efectos de las interacciones del sector minero con el medio ambiente, con énfasis en el enriquecimiento con metales de distintas matrices ambientales (suelos, aguas superficiales y marinas).
  • Determinar cuan sustentable es el sector minero nacional ante distintos escenarios productivos y alternativas de mitigación y rehabilitación ambiental.
  • Evaluar la relevancia de los aspectos históricos y sociales en la relación minería y medio ambiente a nivel nacional.
  • Desarrollar y validar metodologías de rehabilitación ambiental adecuadas a la realidad nacional.
  • Apoyar a los reguladores en la generación de nuevas regulaciones y guías metodológicas pertinentes, además de apoyar la revisión de normativas existentes.
  • Transferir los conocimientos a los actores involucrados y aportar a la formación de nuevo capital humano a nivel nacional en el ámbito de la interacción minería y medio ambiente.

PROYECCIONES:

Dentro de los desafíos relevantes para esta línea está el mejorar la coordinación entre los actores involucrados a nivel nacional en el ámbito de la minería y el medio ambiente (reguladores, empresas mineras, empresas consultoras ambientales, comunidades, ONGs, etc). El mejorar la vinculación entre los actores es fundamental, de alto impacto y relevancia. Adicionalmente, la transferencia de distintos productos (apoyo a normativas, metodologías, formación de capital humano avanzado, difusión de conocimientos a la sociedad civil, etc.) resultará clave para apoyar esta vinculación.

Research:

The mining industry is related in various ways to the environment. Some of these interactions have been over-focused, particularly perceived by society as «negative»; other potential interactions with neutral or positive effects have been, on the other hand, sub-considered or undervalued not only by society but also by the mining industry itself. Additionally, there is an extensive discussion among stakeholders (regulators, employers, communities and researchers, among others) on the feasibility of mining in a sustainable way. In this research the CAPES will bring history to allow objectify the effects of the interactions of the mining sector to the environment, with emphasis on enrichment with metals of different environmental matrices (soil, surface and marine waters), and determine how sustainable is this productive sector to various production scenarios. For example, aspects of ecological risk assessment of enrichment with metals (bioavailability, toxicity to organisms and environmental mobility), contributing to the identification of appropriate methodological tools will address risks. Various alternatives for ecological rehabilitation disturbed by the mining industry, based on rebuilding self-sustaining ecosystems sites will be developed. All this knowledge, tools and approaches will be transferred to the mining industry, regulators and society at large, so as to enable sustainable development of the mining sector. Additionally, he will tend to specialized training in these lines of human capital.

Objectives:

1) Objectify the effects of the mining sector interactions with the environment , with emphasis on metal enrichment in different environmental matrices (soil, surface and marine waters).

2) Determine how sustainable is the national mining sector to various alternative scenarios productive and environmental mitigation and rehabilitation.

3) Assess the relevance of the historical and social aspects of mining and environment relationship at the national level.

4) Develop and validate methodologies for environmental rehabilitation appropriate to the national reality.

5) Support regulators in generating new regulations and relevant methodological guides, in addition to supporting the review of existing regulations.

6) Transferring knowledge to stakeholders and contribute to the formation of new human capital at the national level in the field of mining and environmental interaction.

Actual research lines:

1) Integrate management of mining waste and organic waste for assisted phytostabilization cost-effective.

2) Methodology environmental rehabilitation post coal mining.

3) Improvement of propagation steps and post- transplant native woody species for the rehabilitation of degraded areas.

4) Improving the Competitiveness of Mining and Energy through Reduced uncertainty associated with environmental permitting.

5) Analysis of socio- environmental conflicts for mining.

6) Stress tolerance mechanisms for copper and other environmental stresses in intertidal marine algae. Bioavailability and toxicity of metals in the soil for the plants.

Projections and challenges:

Among the important challenges for this line is the better coordination among stakeholders at the national level in the field of mining and the environment (regulators, mining companies, environmental consulting companies, communities, NGOs, etc). Improving the linking between actors is fundamental, high impact and relevance. Additionally, the transfer of various products (support for standards, methodologies, training of advanced human capital, knowledge dissemination to civil society, etc. ) will be key to support this linkage .
