Growth inhibition of Gyrodinium instriatum (Dinophyceae) by Skeletonema costatum (Bacillariophyceae)
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: S Nagasoe S Toda Y Shimasaki Y Oshima T Uchida T HonjoInteractions between the red tide-forming dinoflagellate Gyrodinium instriatum Freudenthl et Lee and the diatom Skeletonema costatum (Greville) Cleve were investigated in bialgal cultures. The growth rates and maximum cell densities of G. instriatum decreased dramatically in cultures containing S. costatum... -
Vestigial appendicular skeletons in the African and Malagasy skink species Feylinia grandisquamis, Melanoseps ater, Grandidierina lineata and Voeltzkowia mira
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Rachel Liniewski --- , , USA Shane Stanley --- , USA Julia Andrade --- , , USA Phil Senter --- , , USAVestigial appendicular skeletons are present but have not previously been described and illustrated in the skink species Feylinia grandisquamis and Melanoseps ater. Vestigial appendicular skeletons have been described and illustrated in only one specimen of Grandidierina lineata and in a... -
Appendicular skeleton of the vestigial-limbed African skink Eumecia anchietae
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Shane G. Stanley --- , , USA Rachel M. Liniewski --- , , USA Philip J. Senter --- , , USAWithin the lizard family Scincidae (the skinks) are numerous examples of species with vestigial limbs and girdles, but these vestigial structures remain undescribed for many such species. Here we seek to partially fill this gap in knowledge by describing the... -
Sheddable armour: identification of osteoderms in the integument of Geckolepis maculata (Gekkota)
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Daniel J. Paluh --- , , USA Aaron H. Griffing --- , , USA Aaron M. Bauer --- , , USAOsteoderms are bony deposits that form within the dermal layer of skin in vertebrates. Within geckos, osteoderms are uncommon, only described in Gekko gecko and the genus Tarentola. A previous report of osteoderms in the Afro-Malagasy gekkonid genus Geckolepis has... -
A construction of the assembly of a frame
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Richard N. Ball --- University of Denver, U.S.AWe offer here a particularly simple and direct construction of the congruence frame of a given frame, aka its assembly, from the bounded meet semilattice of differences of frame elements. The construction enables economical proofs of two of the assembly’s...
