(Scientific Technical Research Council Turkey-Tubitak, 2005)In this study, a total of 30 Escherichia coli isolates obtained from milk samples of dairy cows suffering from subclinical mastitis in Konya, Turkey were typed according to plasmids and protein patterns. Agarose gel ... -
Pollen studies on some species of the genus Convolvulus L. (Convolvulaceae) from Morocco
(2002)The pollen grains of nine species of Convolvulus L. from Morocco were studied using scanning electron microscopy and light microscopy. The species belong to three sections and four subsections: sections Convolvulus, ... -
Pollination Ecology, Specialization, and Genetic Isolation in Sympatric Bee-PollinatedSalvia(Lamiaceae)
(UNIV CHICAGO PRESS, 2020)Premise of research. Previous pollination ecology studies ofSalviahave shown that there is low specialization for certain subgroups of bees and that pollinator number varies with species and locality. We studied 12Salviaspecies ... -
Pollinator shifts, contingent evolution, and evolutionary constraint drive floral disparity inSalvia(Lamiaceae): Evidence from morphometrics and phylogenetic comparative methods
(WILEY, 2020)Switches in pollinators have been argued to be key drivers of floral evolution in angiosperms. However, few studies have tested the relationship between floral shape evolution and switches in pollination in large clades. ... -
