(Wiley, 2010-10)It has been proposed that aridity and grazing are convergent selective forces: each one selects for traits conferring resistance to both. However, this conceptual model has not yet been experimentally validated. The aim ... -
Differential water-use strategies and drought resistance in Trichloris crinita plants from contrasting aridity origins
Quiroga, Raul Emiliano; Fernandez, Roberto J.; Golluscio, Rodolfo Angel; Blanco, Lisandro Javier (2013-08)In arid environments, water availability is the main limiting factor for primary production, and it is expected that not only drought-resistance, but also plant strategies for soil water use will be under natural selection. ...
