Beak morphology predicts apparent survival of crossbills: due to selective survival or selective dispersal?

Dozens of morphologically differentiated populations, subspecies and species of cross- bills (genus Loxia) exist. It has been suggested that this divergence is due to variation in the conifer cones that each population specialises upon, requiring a specific beak size to efficiently separate the cone scales. If so, apparent survival should depend on beak size. To test this hypothesis, we undertook

Enabling the diffusion of sustainable product innovations in BIM library platforms

Building Information Modelling (BIM) objects represent building products in design, simulation, and procurement processes. This paper explores how BIM objects could be created and exchanged to enable the diffusion of innovative products with enhanced sustainability performance. Two BIM library platforms were examined by taking a new approach that integrates the concepts of sustainable value, diffu
