Functional groups of Sahelian trees in a semiarid agroforestry system of Senegal
Diémé, Joseph Saturnin; Armas, Cristina; Diouf, Mayécor; (2018-06)Aims Addressing plant responses to water stress is critical to understand the structure of plant communities in water-limited environments and to forecast their resilience to future changes in climate. In a semiarid ... -
Functional responses of four Sahelian tree species to resource availability.
Diémé, Joseph Saturnin; Armas, Cristina; Rush, Graciela (2019)Plants experience a fluctuating environment in time and space that affects resource supply. As human impacts on the environment directly and indirectly alter resource availability, it is important to address plant responses ... -
Higher leaf nitrogen content is linked to tighter stomatal regulation of transpiration and more efficient water use across dryland trees
Diémé, Joseph Saturnin; Querejeta, Jose Ignacio; Prieto, Ivan; Armas, Cristina; Casanoves, Fernando; Diouf, Mayécor; Yossi, Harouna; Kaya, Bocary; Pugnaire, Francisco I.; Rusch, Graciela M. (2022)The least-cost economic theory of photosynthesis shows that water and nitrogen are mutually substitutable resources to achieve a given carbon gain. However, vegetation in the Sahel has to cope with the dual challenge ...
