Table 1 The importance of VPD, LAI, and their interaction for explaining variation in mean elongation for species with domed nests and for those with cup-shaped nests, and the proportion of species with domed nests. Elongation is the ratio of egg length to egg breadth. *Indicates a variable that contributed significantly to model (p < 0.05).

From: Variation in avian egg shape and nest structure is explained by climatic conditions
