摘要: Abstract The Laysan Finch (Telespiza cantans) is an endangered Hawaiian honeycreeper that occurs on only a few small islands in the northwestern Island Archipelago. Twenty-two years of recent population estimates (1991–2012) from were analyzed to ascertain current status this species; entire 44 years census data available then used identify long-term trends. have exhibited extreme fluctuations can be attributed at least part spring rainfall patterns. average size has remained ∼10,000 individuals. Poisson regression analysis conducted for last 22 years indicates slightly deceasing annual trend. However, when all included comprehensive trend analysis, stable was documented. These results highlight importance sets monitoring closed populations - situation commonly encountered with...
