Abstract
The present work characterizes trie feeding habits of the Jutía Conga (Capromys pilorides) for the species of trees and bushes consumed and its selectivity. The observations uiere carried out in four vegetable formations of the Reservation of the Biosphere Península of Guanahacabibes (semideciduousforest, marsh forest, vegetation ofsandy coast and xeromorfic coastal forest). The degree of affectation of the vegetation was ualued in 1 75 plots of O, 04 ha there is (75 in semideciduous forest, 50 in the marshforest and 25 in the sandy coast and in xeromorfic coastal forest respective/y). The selectivity degree (S¡) it was measured by an index that keeps in mind the abundance ofthe species in the environment. In semideciduous forest the species overexploited was Oxandra lanceolada /S, = 0,22608), in the forest marshit was Thrinax radiata (S, = 0,32053). In the vegetation of sandy coast the biggest overexploited was Gerascanthus gerascantoide (S, = O, 051609). In the formation of xeromorphic coastal Jorest the jutía overexploited the species Gerascanthus gerascantoide /S, = 0,086106), which the most overexploited of the forty species registered in the [our vegetable formations. The species overexploited uiere selected in very unequal degrees. It is concludes that the jutia conga is a herbiuore opportunist that uses different foruging behavior depending ofthe tree species and its abundance.
