Higher Phosphorus And Water Use Efficiencies And Leaf Stoichiometry Contribute To Legume Success In Drylands
Acuña‐Acosta, D. M., Castellanos, A. E., Llano‐Sotelo, J. M., Sardans, J., Peñuelas, J., Romo‐Leon, J. R., Koch, G. W.

Legumes are essential plants in dryland ecosystems worldwide because they increase nitrogen availability, so their understanding is vital for improving knowledge and modelling in the face of climate change.
This work studies the differences in resource use efficiency and their relationship with photosynthetic, photochemical, bioelemental, …

Diferentes Estrategias En Las DináMicas De Flujo De Savia Y Nicho HidrolóGico De áRboles Dominantes En El Desierto Sonorense Posibilitan Su Coexistencia
Martínez-Núñez, E., Castellanos, A. E., Basant, S., Ortega, C., Wilcox, B. P., Yépez, E. A., Rodríguez, J. C., Romo-León, J. R.

Background: Plants in arid ecosystems exhibit adaptive traits to periodic droughts. It is predicted that droughts will become more frequent and intense due to global change. Studying plant ecophysiological traits will help understand their adaptations to water limitations. In arid ecosystems of northwestern Mexico, evergreen and …

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 …

Respuestas De Los Atributos FotosintéTicos Y EstequioméTricos A La Aridez En Las Especies Y Tipos Funcionales De Dos Comunidades Del Desierto Sonorense
Acuña-Acosta, D. M., Castellanos-Villegas, A. E., Llano-Sotelo, J. M., Romo-León, J. R.

Background: Plants in drylands have developed several water use efficiency (WUE) adaptations, although nutrient limitations and excess irradiances affect also their performance. Previous findings of high photosynthetic rates and nitrogen concentration in leaves, may contradict the known low productivity in their communities.

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 …
