The observed changes have involved a southward shift in breeding distribution or the rapid growth of colonies located on or beyond previous limits. The rate of change appears to have accelerated over the last three decades. A study that encompassed the entire establishment period of one frontier colony  was used as a framework for a demographic transition model extrapolated to other frontier colonies. A wide range of historical observations, together with more detailed recent studies, are brought together to propose a general hypothesis to explain the observed changes in tropical seabird population dynamics in the region.</span></p> </div> </body> </html>
