Modeling the demography and population dynamics of a subtropical seabird, and the influence of environmental factors

摘要: ABSTRACT The use of long-term ecological datasets to explore the importance effects environmental variability on higher predator populations has been focused mainly high-latitude areas. We modeled population dynamics Westland Petrel (Procellaria westlandica), which spends its time mostly in subtropical waters during both breeding and interbreeding migration across Pacific Ocean. found that slowly increased since early 1970s, a result high adult survival, fecundity (0.6 all eggs laid survived fledge) moderate mean age at first return colony (7.7 yr; recruitment typical for this genus), strong rate juveniles, negligible emigration. trends were supported by similar rates increase nest occupancy 2001 density 2007. Annual survival breeders was same sexes (0.954, 95% CI: 0.918–0.975) constant years. However, nonbreeders ha...
