Transience in the humpback whale population of New Caledonia and implications for abundance estimation
International audience A phenomenon of transience in the humpback whale population breeding in New Caledonia has been highlighted in recent analyses. We used these data to illustrate the risk of flawed inference when transience is not properly accounted for in abundance estimation of resident popula...
