Therefore, high incipient colony densities recorded on larger landmasses cannot be attributed to greater nest-site availability.
There were significant treatment x landmass category and species x treatment interactions.
The survival of unprotected incipient and young colonies was significantly reduced on larger landmasses relative to small islands.
There were two levels of the cage factor (protected and unprotected) and three levels of the landmass size factor (small, medium and large).
Incipient colonies showed the reverse trend with higher densities on larger landmasses.
Post-hoc contrasts between landmass categories served to identify significant differences.
This suggests that esterification reactions were likely to commonly occur in the prebiotic environment as available reactants underwent cycles of wetting and drying on early landmasses at elevated temperatures.
The remaining maps are difficult to read because of the poor contrast between the blue of the sea and green used for landmasses.
