Özet:

 


                 
                        The prickly pear (Opuntia ficus-indica L.
 Miller) is a xerophytic cactus species widely cultivated in arid and 
semiarid regions worldwide and used in rehabilitation programs of 
rangelands in Algeria since 1990. This study analyzed the diversity and 
functional traits of plant species established in prickly pear 
plantations growing under arid and semiarid climates. A 3-year plant 
assessment (2008-2010) was carried out using ecological descriptors 
(abundance, species richness, diversity indices, disturbance index, and 
Jaccard index) and plant functional traits (life forms, chorological 
types, dispersal types, Grime's, Noy-Meir's strategies, and 
morphological types). The results revealed 36 and 31 species in arid and
 semiarid rangelands, respectively, with remarkable dominance of 
therophytic
(43.2%) and hemicryptophytic plants (41.1%) growing in the semiarid 
climatic zone. The Shannon and diversity index showed low values 
(0.93-1.84 in surveyed rangelands) with a maximum of 2.74 in 2009. The 
disturbance index ranged between 51% and 55% and the dispersion scheme 
of diaspores was dominated by anemochorous plants. The chorological 
analysis indicated that the study plants were oriented towards a 
Mediterranean pattern in the broad sense. The predominant adaptive 
strategies of Grime were ruderal-stresstolerant (RS), 
competitive-stress-tolerant (CS) and competitive-ruderals (CR), which 
were attached to the two strategies of Noy-Meir
(aridopassives and aridoactives).
