Última Seed Predation of Copaifera langsdorffi Desf. (Fabaceae: Caesalpinioideae) by Rhinochenus brevicollis Chevrolat (Coleoptera: Curculionidae) in a Brazilian Cerrado Fragment Ecología austral Fagundes,Marcílio; Maia,Maria L.B.; Queiroz,Antônio C.M.; Fernandes,G.W; Costa,Fernanda V.. Seed predator insects are generally highly specialized herbivores that can be affected by several plant characteristics. In this study, the resource concentration hypothesis and the plant architecture hypothesis were tested by evaluating the attack of Rhynochenus brevicollis on Copaifera langsdorffi seeds. The study was conducted in a cerrado fragment situated in southeastern Brazil. The percentage of C. langsdorffi seed predation by R. brevicollis ranged from 1 to 30% (mean±SD, 9.31±6.41). The percentage of seed predation was negatively related to the number of fruits per branch. The predation of seeds by the beetle was positively affected by plant crown circumference, while plant height did not show any relationship with seed predation. Thus, our results...

Parkia pendula occurs in Brazil in Amazonia and in the northeastern Atlantic Forest. In the latter, its buds, nectar, and seedpod gum are discussed to be keystone resources for the mammalian fauna. To enhance the knowledge about these important nourishment sources, the aim of this study was to detect and describe distinct phases in the flower and pod development. The study was conducted in a 306 ha forest fragment in Igarassu, Pernambuco, northeastern Brazil. Six morphometrical variables were measured weekly at five inflorescences of two individuals from September 2003 to January 2004. Eleven distinct developmental phases were identified in the 21 weeks lasting development from the very first inflorescences to mature pods and are described in detail. These...
