摘要

野生蜜蜂对农业和自然生态系统的功能至关重要,但这些传粉者群落在世界范围内正在减少。由于生境和花卉资源的丧失而导致的农业集约化被认为是野生蜜蜂种群恶化的主要原因之一。这项研究调查了新罕布什尔州的多种农业用地系统,以确定不同的土地利用做法如何影响野生蜜蜂的生物多样性和社区相互作用。调查共采集野生蜜蜂112种2292只。所有土地利用系统均存在高度的物种重叠,但也存在一定的物种独占性。土地利用显著影响物种的丰度和丰富度。适度管理的样地具有最大的传粉媒介丰度和物种丰富度,而低管理的样地具有最小的丰富度和与高管理样地相同的丰富度。本研究结果支持了花卉景观多样性在蜜蜂保护工作中的重要性,并表明并非所有农业实践都对传粉者群落产生负面影响。

Wild Bee Community Assemblages Across Agricultural Landscapes1
ABSTRACT Wild bees are essential to the functioning of both agricultural and natural ecosystems, yet these pollinator communities are declining worldwide. Agricultural intensification by means of habitat and floral resource loss is thought to be one of the leading causes of wild bee population deterioration. This study examined multiple agricultural land use systems in New Hampshire to determine how wild bee biodiversity and community interactions are affected by different land use practices. A total of 2292 wild bees were collected during these surveys, representing 112 species. A high species overlap was found at all land use systems, although all sites had some species exclusivity. Land use significantly affected species abundance and richness. The moderately managed sites supported both the greatest pollinator abundance and species richness, while the low management sites had the smallest abundance and the same level of richness as the high management sites. The findings of this study support the importance of floral landscape diversity in bee conservation efforts and suggest that not all agricultural practices negatively affect the pollinator community.

期刊介绍: The Journal of Agricultural and Urban Entomology (JAUE) (Journal of Agricultural Entomology, Jan 1984 - Oct 1998 volumes 1-15) is published under the auspices of the South Carolina Entomological Society (SCES). The Journal publishes contributions of original research concerning insects and other arthropods of agricultural and urban importance to include those affecting humans, livestock, poultry, and wildlife. JAUE is particularly dedicated to the publication of articles and notes pertaining to applied entomology, although it will accept suitable contributions of a fundamental nature related to agricultural and urban entomology.
