摘要

To conserve native plants, pollinators and their nesting habitats must also be protected. Indicator plants for nesting sites of the native leafcutter bee Megachile wheeleri Mitchell were characterized within a Northern California coastal dunes preserve. Nesting was restricted to the Poa-Lathyrus plant community. Significant positive associations were detected between bee nests and Aira praecox L., A. caryophyllea L., Solidago spathulata DC., Juncus lesueurii Bolander, and mosses; negative associations with Carex obnupta L. Bailey and Lathyrus littoralis (Nuttall) Endlicher. Nest density and total plant cover were not significantly correlated. Nests were generally not constructed near the bee's host plants. Most nesting occurred in a zone transitional between mesic lowlands and xeric higher elevations. Natural successional change was increasing nesting habitat, but climax shore pine-spruce forest should eventually eliminate nesting habitat in the long term if succession is not disturbed. The introduced plants Lupinus arboreus Sims and Ammophila arenaria L. may eliminate nest habitat, but Aira praecox L. and A. caryophyllea L. may enhance it. Other bee and wasp species were present in samples but no significant associations with plants were detected because densities were so low. Very large sample sizes will be required to determine significant associations for those species. M. wheeleri nests ranged from dense aggregations to scattered individual nests. Other bee and wasp species also nested within M. wheeleri nest aggregations, including the sphecid wasp Bembix americana comata J. Parker, which normally nests in barren sand. Native plant restoration activities may benefit from restoration of native pollinators.

Bailey和Lathyrus littoralis（Nuttall）Endlicher呈负相关。巢密度和总植物覆盖率没有显着相关。通常不在蜜蜂的寄主植物附近筑巢。大多数筑巢发生在中陆低地和干燥高地之间的过渡带。自然的演替变化增加了筑巢栖息地，但是如果不干扰演替，高潮的松树云杉林最终应从长远来看最终消除筑巢栖息地。引入的植物羽扇豆Sims和Ammophila arenaria L.可能会消除巢穴栖息地，但Aira praecox L.和A. caryophyllea L.可能会增强巢穴栖息地。样品中还存在其他蜜蜂和黄蜂物种，但由于密度极低，因此未检测到与植物的显着关联。需要非常大的样本量才能确定这些物种的重要关联。 M. wheeleri巢的范围从密集的聚集到分散的单个巢。其他蜜蜂和黄蜂物种也筑巢于M. wheeleri巢聚集体中，其中包括通常在贫瘠的沙子中筑巢的长寿黄蜂Bembix americana comata J. Parker。原生植物的恢复活动可能得益于原生授粉媒介的恢复。
