Plant functional diversity influences water and carbon fluxes and their use efficiencies in native and disturbed dryland ecosystems
Castellanos, A. E., C. Hinojo-Hinojo, J. C. Rodríguez, J. R. Romo-Leon, B. P. Wilcox, J. A. Biederman, J. Peñuelas

Vegetation is changing rapidly in dryland ecosystems, but critical gaps remain in understanding the long-term fluxes of carbon (C) and water. We used 6 years of data from two adjacent eddy covariance sites in the Sonoran Desert, a species-rich woody C3 native shrubland and a species-poor C4 shrubland converted to buffelgrass savanna. …

Contrasting Effects Of Native And Exotic Vegetation On Soil Infiltrability In The Sonoran Desert
Leite, P. A., Castellanos, A. E., Wilcox, B. P., Vega-Puga, M., Martínez, E., Dennis, S., Choza, S., Acuña-Acosta, D. M.

Invasion by exotic grasses is transforming drylands across the planet, but the ecohydrological feedbacks of such invasions are not fully understood. For example, in the Sonoran Desert, previous studies have shown that buffelgrass (Cenchrus ciliaris) alters the spatial patterns of soil moisture, leading researchers to hypothesize …

Native Shrubland And Managed Buffelgrass Savanna In Drylands: Implications For Ecosystem Carbon And Water Fluxes
Hinojo-Hinojo, C., Castellanos, A. E., Huxman, T., Rodriguez, J. C., Vargas, R., Romo-León, J. R., Biederman, J. A.

Land cover and land-use change (LCLUC) between woody- and grass-dominated ecosystems in drylands comprise one of the largest uncertainties in the land CO2 sink. This is especially true for the widespread transition from shrublands to grasslands/savannas caused by the establishment of exotic C4 grass species for grazing or through …

Ecohydrological Changes In Semiarid Ecosystems Transformed From Shrubland To Buffelgrass Savanna
Castellanos, A. E., Celaya‐Michel, H., Rodríguez, J. C., Wilcox, B. P.

In arid and semiarid lands worldwide, vegetation cover is being transformed to savannas dominated by exotic grasses. However, the ecohydrological and biogeochemical changes associated with this process remain little understood. For more than 3 years, we studied soil moisture dynamics in natural semiarid shrubland patches and compared …

Carbon And Water Fluxes In An Exotic Buffelgrass Savanna
Hinojo-Hinojo, C., Castellanos, A. E., Rodriguez, J. C., Delgado-Balbuena, J., Romo-León, J. R., Celaya-Michel, H., Huxman, T. E.

Buffelgrass savanna is becoming widespread in aridland ecosystems around the world following invasion or deliberate land conversion for cattle forage. There is still a gap of information regarding functional and ecohydrological aspects such as carbon, water, and greenhouse gas exchanges in these highly productive novel ecosystems …

Cambios en el almacenamiento de nitrógeno y agua en el suelo de un matorral desértico transformado a sabana de buffel (Pennisetum ciliare (L.) Link)
Celaya-Michel, H.,, F. García-Oliva,, J. C. Rodríguez, A. E. Castellanos-Villegas

El cambio de uso de suelo es uno de los principales factores de la degradación de los ecosistemas naturales, al modificar los procesos de transferencia de nitrógeno y agua reduciendo su productividad. En el presente trabajo, se describe cómo la transformación de matorrales desérticos a sabanas de zacate buffel en la región …
