Seed deposition in the edge-interior gradient of a degraded fragment of tropica...
Diogo, Ivan J. S.; Fortunato, Márcia E. M.; Costa, Itayguara R.The structure, dynamics and density of plant populations in different ecosystems are controlled by climatic seasonality. Seed rain contributes to both establishment and maintenance of the forest as well as to the recovery of disturbed areas near forest fragments. The aim of this study was to assess the deposition rate of different seeds of endemic and exotic tree species for the edge and for the interior of the...
Myrteae phylogeny, calibration, biogeography and diversification patterns: Incr...
Vasconcelos, Thais N. C.; Proença, Carol E. B.; Ahmad, Berhaman; Aguilar, Daniel S.; Aguilar, Reinaldo; Amorim, Bruno S.; Campbell, KeronMyrteae (c. 2500 species; 51 genera) is the largest tribe of Myrtaceae and an ecologically important groups of angiosperms in the Neotropics. Systematic relationships in Myrteae are complex, hindering conservation initiatives and jeopardizing evolutionary modelling. A well-supported and robust phylogenetic hypothesis was here targeted towards a comprehensive understanding of the relationships within the tribe. ...
Pleistocene radiation of coastal species of Pilosocereus (Cactaceae) in eastern...
Menezes, Marcelo O. T.; Zappi, Daniela C.; Moraes, Evandro M.; Franco, Fernando F.; Taylor, Nigel P.; Costa, Itayguara R.; Loiola, Maria I. B.The semiarid region in Northeast Brazil (Caatinga) suffered several high moisture periods during the Pleistocene, while neighbouring regions experienced drying events. Effects of this climatic history on the evolution of Caatinga xeric flora are poorly understood. Demography and evolutionary relationships between Pilosocereus arrabidae and Pilosocereus catingicola (Cactaceae) were investigated using two noncodi...
