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 …

Carbon Fluxes From A Temperate Rainforest Site In Southern South America Reveal A Very Sensitive Sink
Perez-Quezada, J. F., Celis-Diez, J. L., Brito, C. E., Gaxiola, A., Nuñez-Avila, M., Pugnaire, F. I., Armesto, J. J.

Ecosystems where carbon fluxes are being monitored on a global scale are strongly biased
toward temperate Northern Hemisphere latitudes. However, forest and moorland ecosystems in the Southern Hemisphere may contribute significantly to the global and regional C balance and are affected by different climate systems. Here, we present …

How many measurements are needed to estimate accurate daily and annual soil respiration fluxes? Analysis using data from a temperate rainforest
Pérez-Quezada, J., Brito, C.E., Cabezas, J., Galleguillos, M., Fuentes, J.P., Bown, H., Franck, N.

Making accurate estimations of daily and annual Rs fluxes is key for understanding the carbon cycle process and projecting effects of climate change. In this study we used high-frequency sampling (24 measurements per day) of Rs in a temperate rainforest during 1 year, with the objective of answering the questions of when and how …
