Effects of plantation intensity on longhorn and carabid beetles in conifer plantations mixed with broadleaved trees in northern Japan ...
Reconciling timber production with biodiversity conservation is essential. Increasing the mixture of broadleaved (BL) trees into conifer plantations increases the abundance of species that prefer natural BL forests but can reduce conifer yields. Therefore, modeling of the relationships of the abunda...

| Summary: | Reconciling timber production with biodiversity conservation is essential. Increasing the mixture of broadleaved (BL) trees into conifer plantations increases the abundance of species that prefer natural BL forests but can reduce conifer yields. Therefore, modeling of the relationships of the abundances of various taxa with conifer and BL trees is necessary for effective biodiversity conservation. Longhorn and carabid beetles are useful ecological indicators; however, their responses to the amount (e.g. basal area and coverage) of conifer and BL trees within stands remain unknown. We surveyed the abundances of longhorn and carabid beetles in plantations of Todo fir Abies sachalinensis and Sakhalin spruce Picea glehnii mixed with various amounts of BL trees and in natural BL forests. We analyzed the response of each taxon to the basal area of conifer trees (CBA) within stands. Unexpectedly, for longhorn beetles, no effect of CBA was detected for species using BL trees as larval host plants and the effect was ... |
