Zool., 31:113-135.-In principle, any measured distances between landmarks of a form may serve as characters for morphometric analyses. Systematic studies typically are based on a(More)
One pervasive morphological feature of tetrapods is the pipe-like, often marrow-filled, structure of the limb or long bones. This 'hollow' form maximizes flexural strength and stiffness with the minimum amount of bony material, and is exemplified by truly hollow (air-filled), or pneumatic, humeri in many modern birds. High-resolution microCT scans of the(More)
The morphology of the swim bladder and inner ear of the nurseryfish, Kurtus gulliveri, appear adapted for enhanced pressure wave reception. The saccule is enlarged and surrounded by very thin bone and two large fontanelles that would present reduced resistance to pressure waves. The swim bladder is elaborate, with six dorsolaterally projecting pairs of(More)
Three nutrients, iron, zinc and pro-vitamin A, are widely deficient in humans, especially among low socioeconomic groups in developing countries, but they remain significant concerns in industrialized countries as well. Cereals provide the majority of the intake of these nutrients in low-income families. Moreover, these three nutrients may interact(More)
Life science identifier (LSID) is a global unique identifier standard intended to help rationalize the unique archival requirements of biological data. We describe LSID implementation architecture such that data managed by a relational database management system may be integrated with the LSID protocol as an add-on layer. The approach requires a database(More)
