Molecular Phylogenetics Of Vandeae (Orchidaceae) And The Evolution Of Leaflessness, Barbara Carlsward, W. Whitten, Norris Williams, Benny Bytebier Jan 2006

Molecular Phylogenetics Of Vandeae (Orchidaceae) And The Evolution Of Leaflessness, Barbara Carlsward, W. Whitten, Norris Williams, Benny Bytebier

Faculty Research & Creative Activity

Members of tribe Vandeae (Orchidaceae) form a large, antropical clade of horticulturally important epiphytes. Monopodial leafless members of Vandeae have undergone extreme eduction in habit and represent a novel adaptation to the canopy environment in tropical Africa, Asia, and America. To study the evolution of monopodial leaflessness, molecular and structural evidence was used to generate phylogenetic hypotheses for Vandeae. Molecular analyses used sequence data from ITS nrDNA, trnL-F plastid DNA, and matK plastid DNA. Maximum parsimony analyses of these three DNA regions each supported two subtribes within monopodial Vandeae: Aeridinae and a combined Angraecinae þ Aerangidinae. Adding structural characters to …

Fungal Spore Dispersal By The Eastern Box Turtle (Terrapene Carolina Carolina), S. C. Jones, W. J. Jordan, Scott J. Meiners, A. N. Miller, A. S. Methven

Faculty Research & Creative Activity

Although spores from most macrofungi are wind- or water-dispersed, dispersal may also occur via biotic vectors. The Eastern box turtle (Terrapene carolina carolina) is a facultative mycovore that may play an important role in fungal spore dispersal although, to date, no information exists on fungi occurring in fecal samples of box turtles or on the ecological significance of box turtles as spore dispersal vectors. Consequently, a study of the potential for Eastern box turtles to act as vectors for spore dispersal was initiated by capturing wild turtles and collecting fecal samples. Serial dilutions from fecal samples were made to enumerate …
