Depredación pre-dispersiva de semillas en tres poblaciones del árbol Enterolobium contortisiliquum (Fabaceae)
Get PDFPre-dispersal seed predation in three populations of the tree Enterolobium contortisiliquum (Fabaceae). Predation is an important selective force that has shaped different strategies related to size, quantity and production time of fruits, seeds and seed reserves. The seeds of E. contortisiliqum are predated by the bruchid Merobruchus bicoloripes. We collected 1 300 fruits from 26 trees in San Salvador de Jujuy (Jujuy province), Castañares, and San Lorenzo (Salta province) Argentina. San Lorenzo is the wettest and highest site, while Castañares is the driest and lowest site. Jujuy is in the middle. In the laboratory, the fruits from each site were weighted and divided in three groups (small, medium and big). We counted the mature and predated seeds per fruit. In San Lorenzo, seed predation was higher in medium sized fruits while in Castañares and Jujuy seed predation was higher in both medium and bigger fruits. However, only in San Lorenzo we found a significant difference in preference for medium size fruits
