This work had as objective to evaluate the dispersion of the seeds of imbuzeiro (Spondias tuberosa Arruda) for the animals and the survival of plants in caatinga. The work was carried out in the period from October of 2002 to December of 2005 in degraded and native area of caatinga. They had been selected to perhaps, 16 plants of imbuzeiro, being eight plants in each area. In each plant twelve transectos of 1 m of width for 25 m had been demarcated, where the seeds found in the young ground and plants. The used experimental delineation was block-type to perhaps in factorial project 5 x 2, with four repetitions. 1003.5 seeds.m-2 had been, on average, in the first units you show of caatinga native and in caatinga degraded, it was observed, on average, 31.25 seeds m-2. In the native area of caatinga they had been registered 2.5 plants m-2, on average, in the first units you show during the rainy station. The dispersive ones of the seeds observed in the native area of catinga had been the deer-catingueiro (Mazama gouazoubira), the cotia (Dasyprocta cf. prymnolopha), caititu (Tayassu tajacu), the fox (Dusicyon thous), the teiú (Tupinambis merianae), the tatu-peba (Euphractus sexcinctus) of the guará (Procyon cancrivous) the area of caatinga e na área de caatinga degraded the sheep (Capra hircus).Key-words: rain, tree, seedlings, emergency, germination. |
