Diversity and Indicator Role of Scarabaeoidea in Different Habitats of Natural Broad-Leaved Mixed Forest-Young Pinus koraiensis Plantation Forest Ecotone
To provide references for pest control and forest management after returning farmland to forest,the community structure and diversity of Scarabaeoidea in the ecotone between natural forest and plantation forest in northern China were investigated.The natural broad-leaved mixed forest and its adjacent artificial young red pine(Pinus koraiensis)forest were selected as the study areas,and the continuous trapping method was used by pitfall trapping from April to September in 2017 and 2018.A total of 1 498 specimens belonging to 35 species,23 genera and 7 families of Scarabaeoidea were cap-tured.Scarabaeidae and Cetoniidae were highly correlated with P.koraiensis forest.The individual numbers of Oxycetonia jucunda,Protaetia brevitarsis,Onthophagus sinicus,Onthophagus ater and Onthophagus atripennis in P.koraiensis forest were significantly different among habitats(P＜0.05).The numbers of individuals and species in P.koraiensis forest were significantly different among habitats(P＜0.05).The results of NMDS and PERMANOVA showed that there were signifi-cant differences in the community structure of Scarabaeoidea between broad-leaved forest and P.koraiensis forest,ecotone and P.koraiensis forest(P＜0.05).Moreover,the spatial species turnover in the three habitats was higher than the mosaic of species clusters after the decomposition of β diversity.Scarabaeoidea showed a weak negative edge effect in ecotone.This study suggests that Scarabaeoidea may prefer P.koraiensis forest,especially Cetoniidae.Therefore,it is necessary to continuously monitor habitat changes using indicator species and pay attention to large-scale outbreaks of Cetoniidae.
