TL;DR: The results indicate that although pad area is a strong determinant of clinging ability, other factors enable these lizards to maintain functional similarity, and despite the tight correlation between pad area and clingingAbility, pad area scales with body mass by a lower slope than clinging ability.

TL;DR: Clumped resources can increase interspecific exploitation competition, and this mechanism may contribute to spe- cies turnover when human environmental alterations redistribute resources.

TL;DR: Quantifying inbreeding depression in survival and reproduction in populations of cactus finches and medium ground finches living on Isla Daphne Major in the Galapagos Archipelago suggests that substantial inbreeding Depression can exist in insular populations of birds, and that the magnitude of the inbreeding depressed is a function of environmental conditions.

TL;DR: The adaptive radiation of Darwin's finches has occurred in the presence of ongoing but low levels of gene flow caused by distance‐dependent interisland dispersal, concluding that Gene flow does not constrain phenotypic divergence, but may augment genetic variation and facilitate evolution due to natural selection.

TL;DR: Allele length variation at 16 microsatellite loci was used to estimate the phylogeny of 13 out of the 14 species of Darwin's finches, demonstrating the use of microsatellites for reconstructing phylogenies of closely related species and interpreting their evolutionary and biogeographic histories.
