This study demonstrated prediction of breeding success of Black-tailed Gulls in relation to the selected environmental factors through evaluation of relative importance in determining breeding success. The data were obtained from the 258 selected and 120 non-selected sites for breeding of the gulls during the breeding periods in 2002–2003. Breeding success at the selected sites, and environmental...
The factors affecting nest-site selection and breeding success of Black-tailed Gulls (Larus crassirostris) were studied in Hongdo Island in Korea during the breeding seasons in 2002 and 2003. Two analyzing methods, Principal Component Analysis (PCA) and Self-Organizing Map (SOM) – an unsupervised learning method in artificial neural networks, were applied to multivariable datasets characterizing nest-sites...
