Nucleotide substitutions in a gene occur at a relatively constant rate.

A nonsynonymous substitution is a nucleotide mutation that alters the amino acid sequence of a protein. Nonsynonymous substitutions differ from synonymous substitutions, which do not alter amino acid sequences and are (sometimes) silent mutations.

But a Spanish-Argentinean team of researchers has investigated how the collapse of the rabbit population in the late 1980s, triggered by viral haemorrhagic disease (VHD), has adversely impacted the lives of certain carnivores in Doñana National Park, a national park and wildlife refuge in south-western Spain. The findings, published in the journal Basic and Applied Ecology, indicate that the population decline for the most part has affected the lynx; this medium-sized wildcat cannot hunt other prey.
