Daily female counts and fitted census curves in sample years.
Black points are observed counts on single days. The black, bell-shaped curve is the fitted census curve, C ( t ); the blue dotted curve is the estimated cumulative arrival curve, A ( t ); and the dotted red curve the cumulative departure curve, D ( t ). A ( t ) and D ( t ) reach an asymptote at the...

description |
Black points are observed counts on single days. The black, bell-shaped curve is the fitted census curve, C ( t ); the blue dotted curve is the estimated cumulative arrival curve, A ( t ); and the dotted red curve the cumulative departure curve, D ( t ). A ( t ) and D ( t ) reach an asymptote at the total population of females, N i , using the colony in year i . The examples include years with few counts, demonstrating that the model works well with smaller samples, plus sample years from Point Reyes, King Range, and the Channel Islands; these complement our earlier presentation of the model [ 4 ] in which we included similar figures for 18 years at Año Nuevo Mainland, 1978–2006. Abbreviations: ANI, Año Nuevo Island; ANML, Año Nuevo Mainland; PR, Point Reyes; SNI, San Nicolas Island; KR, King Range. Range of the vertical axis varies greatly, but the dates on the horizontal axis are identical, with vertical lines at 1 Jan, 1 Feb, 1 Mar. |
