Ecological Correlates of Extinction Proneness in Tropical Butterflies

摘要: Widespread told rapid losses of natural habitats and biodiversity have made the identification extinction-prone species a major challenge in conservation biology. We assessed relative importance biologically relevant traits (e.g., body size, ecological specialization) obtained from published records to determine extinction probability butterflies highly disturbed tropical landscape (i.e.. Singapore). also developed taxon-specific model estimate Proneness Southeast Asia. Logistic regression analyses showed that adult habitat specialization, larval host plant specificity, geographical distribution, sexual dichromatism, congenor density were significant independent determinants butterfly extinctions Singapore. Among these traits, specificity specialization best correlates risks. used this phenomenological extinction-regression proneness 416 Our results illustrate utility available data for localized area estimating Me closely-related oil regional scale. When intensive field studies are not forthcoming especially regions suffering southeast Asia), similar approaches could be threats other taxonomic groups.
