Precocity, yield and water-use efficiency of banana plants under planting densities and irrigation depths, in semiarid region

open access: yesPesquisa Agropecuária Tropical, 2019
Banana is a crop of major importance for the Brazilian semiarid region. However, because of the low availability and irregularities of the rainfall in this area, it is necessary to combine techniques that allow a higher water-use efficiency.

Spatial mechanisms promoting plant coexistence. the role of dispersal and competition [PDF]

open access: yes, 2009
One of the great challenges in ecology is to explain how large numbers of plant species are able to coexist in natural communities. The role of spatial structure for maintaining plant coexistence has so far mainly been explored by theory.
