Efecto de la interacción entre cambio climático y erosión sobre la vegetación y el suelo. Un caso de estudio en Teruel

Abstract

[ES] Mediante un diseño factorial, se analizaron las consecuencias de la actuación simultánea de dos factores de cambio global sobre las propiedades de los ecosistemas. Usamos como factores el clima y la pendiente del terreno como aproximaciones respectivamente del efecto del cambio climático esperado para mitad del siglo XXI y del efecto de la deforestación. Como propiedades del ecosistema se usaron variables de vegetación y suelo. Los resultados muestran un efecto negativo del cambio climático y de la erosión sobre la riqueza de especies y las propiedades del suelo cuando ambos actúan de manera aislada. Ahora bien, cuando ambos factores actúan simultáneamente, el efecto total es menor que la suma del efecto de ambos por separado, menos para la cobertura vegetal en que el efecto fue igual a la suma. También encontramos que las propiedades del suelo se correlacionan más fuertemente con la riqueza de especies que con la cobertura vegetal.

[EN] In this study we analyze the consequences on ecosystems of the simultaneous action of several factors of global change. For this, we analyze separately and simultaneously the consequences of climate change and erosion on vegetation and soil variables using a factorial design of two climates and two terrain slopes. These factors were used as approximations to the effect of climate change expected for the middle of the 21st century and the effect of deforestation. The results indicate that when climate change and erosion act independently, their effects are negative on all variables. However, when both factors act simultaneously, their effects on species richness and soil properties are lesser than the sum, except in the case of vegetation cover, where the effects of climate change and erosion add up. We also find that soil properties correlate more strongly with species richness than with plant cover.
