Evolution on a volcanic conveyor belt: using phylogeographic reconstructions and K-Ar-based ages of the Hawaiian Islands to estimate molecular evolutionary rates.

TL;DR: K–Ar estimates of the date of an island’s formation provide a maximum age for the taxa inhabiting the island and can be used to calibrate rates of molecular change under the following assumptions: (i) K–Ar dates are accurate; (ii) tree topologies show that derivation of taxa parallels the timing of island formation;
Journal ArticleDOI

A noninvasive method for distinguishing among canid species: amplification and enzyme restriction of DNA from dung

TL;DR: To detect and study the endangered kit fox, mitochondrial DNA markers that can be amplified from small amounts of DNA extracted from scats are developed that discriminated among all five canid species and correctly identified 10 ‘unknown’ fox scats to species in blind tests.
Journal ArticleDOI

Natural selection of the major histocompatibility complex (Mhc) in Hawaiian honeycreepers (Drepanidinae).

TL;DR: The notion that balancing selection operates at the Mhc in the honeycreepers is supported by transpecies polymorphism and strikingly high dN/dS ratios at codons putatively involved in peptide interaction.
