| hoverfly (syrphidae) communities respond to varying structural retention after harvesting in canadian peatland black spruce forests. | variable retention harvesting (vrh), in which trees are removed at variable intensity and spatial configuration across the landscape, retains greater forest structural heterogeneity than traditional clear-cut harvesting and is being recommended as an alternative for sustainable management of the boreal forest. little is known about its effects on forest fauna; thus, we studied the influence of one type of vrh (harvesting with advanced regeneration [harp]) on the syrphidae (diptera) community in ... | 2007 | 17445365 |
