Un modelo de sucesión-regeneración de los páramos después de quemas

Caldasia, 1997
The patterns and initial mechanisms of regeneration-succession in paramos after fire disturbance were studied. The model of species life histories was used to form groups with similar vital attributes (discussed by Noble & Slatyer 1980), and lo establish
