- Speciation gradients and the distribution of biodiversity
Immigration (I) is the main source of species on small islands (1 and 2), whereas within-island species origination (W) becomes more important on large islands (3 and 4) (W 1 and W 2 are 0 and
- Biology of the sauropod dinosaurs: the evolution of gigantism
Even the ‘dwarf’ sauropods were animals with an adult body mass well in excess of 500 kg (Peczkis, 1994; Sander et al , 2006; Stein et al , in press), a size which is reached by less than 10% of modern mammal species (Hotton, 1980)

- Comparative analysis reveals within-population genome size . . .
Background Eukaryotic genomes are known to display an enormous variation in size, but the evolutionary causes of this phenomenon are still poorly understood To obtain mechanistic insights into such variation, previous studies have often employed comparative genomics approaches involving closely related species or geographically isolated populations within a species Genome comparisons among
