How Do Land Cover Changes Affect Carbon-Nitrogen-Phosphorus Stocks And The Greenhouse Gas Budget Of Ecosystems In Southern Chile?
Perez-Quezada, J. F., Cano, S., Ibaceta, P., Aguilera-Riquelme, D., Salazar, O., Fuentes, J. P., Osborne, B.

Agricultural land use changes are expected to modify the carbon (C), nitrogen (N) and phosphorus (P) stocks compared to the native ecosystems they replace and result in changes in greenhouse gas (GHG) fluxes. To quantify these effects, we measured C-N-P stocks in four land cover classes (cropland, grassland, native shrubland and …

Long Term Effects Of Fire On The Soil Greenhouse Gas Balance Of An Old-Growth Temperate Rainforest
Perez-Quezada, J. F., Urrutia, P., Olivares-Rojas, J., Meijide, A., Sánchez-Cañete, E. P., Gaxiola, A.

Forest fires can cause great changes in the composition, structure and functioning of forest ecosystems. We studied the effects of a fire that occurred >50 years ago in a temperate rainforest that caused flooding conditions in a Placic Andosol to evaluate how long these effects last; we hypothesized that the effects of fire on …

Effects Of Disturbance On The Carbon Dioxide Balance Of An Anthropogenic Peatland In Northern Patagonia
Valdés-Barrera, A., Kutzbach, L., Celis-Diez, J. L., Armesto, J. J., Holl, D., Perez-Quezada, J. F.

Peatlands are characterized by their large carbon (C) storage capacity and represent important C sinks globally. In southern Chile, young peatlands (few centuries old) have originated due to clearcutting or fire at forest sites with high precipitation on poorly drained soils. These novel ecosystems are called anthropogenic peatlands …

Evaluation of impacts of management in an anthropogenic peatland using field and remote sensing data
Cabezas, J., Galleguillos, M., Valdés, A., Fuentes, J.P., Pérez, C., Pérez-Quezada, J.

Peatlands are a type of wetland characterized by the accumulation of organic matter, called peat, and are important carbon reservoirs. In areas with poor drainage, human-induced forest fires and logging can produce flooded conditions and organic matter accumulation, which generates an ecosystem called anthropogenic peatland. Productive …
