Efecto del sistema de laboreo sobre la diversidad funcional de comunidades arvenses: ¿Merece la pena hacer mediciones locales de los rasgos funcionales?

Abstract

Este trabajo tiene un doble objetivo: i) testar el efecto de tres sistemas de laboreo (laboreo de subsuelo, laboreo mínimo y siembra directa) sobre la diversidad funcional de la comunidad de arvenses; ii) evaluar la necesidad de hacer mediciones locales de rasgos funcionales (área foliar específica (SLA), altura total de la planta y peso de las semillas) para analizar el efecto del tipo de manejo. Se han calculado tres índices de diversidad funcional con los valores de los rasgos obtenidos en la literatura y con los valores de la comunidad local. El efecto del tipo de laboreo sobre estos índices se ha analizado mediante modelos lineales. Los resultados muestran una influencia del origen de los datos a la hora de detectar el efecto del manejo sobre la diversidad funcional de las comunidades arvenses, siendo la siembra directa el sistema que presenta los índices de diversidad funcional más altos.

In this work we aim: i) to test the effect of three tillage systems (subsoil tillage, minimum tillage and no-tillage) on the functional diversity of weed communities; and ii) to assess the need for local measurements of functional traits (specific leaf area (SLA), total height of the plant and seed weight) when assessing the effect of management on weed functional diversity. Three functional diversity indexes have been developed, based on local data and data from the literature. The effect of tillage system on the indexes has been analyzed with linear models. The results show that the origin of the data determines the effect of the soil management on the functional diversity of the weed communities, being no-tillage the system with highest functional diversity indexes.
