摘要
2019年10月至2021年10月,在鹞落坪保护区典型农林交错带采集传粉昆虫2551只,通过形态学及DNA Barcoding互证,鉴定出传粉昆虫92种,隶属于4目34科73属。其中,中华蜜蜂(Apis cerana)、三条熊蜂(Bombus trifasciatus)、灰带管食蚜蝇(Eristalis cerealis)和东方菜粉蝶(Pieris canidia)是优势种。物种多样性分析结果表明,以农田为主的样线Ⅰ比以森林为主的样线Ⅱ和Ⅲ的多样性更高,多样化的农作物能为传粉昆虫提供更好的栖息地和食物来源;样线Ⅲ则因临近旅游区域而受到较多人为干扰,多样性显著较低。此外,从WorldClim数据库中下载19个环境因子(Bio1~Bio19),分析物种及系统发育多样性与研究区域内的环境因子间的相关性关系:其中,有14个环境因子(Bio1,Bio4~13,Bio16,Bio18~19)与系统发育多样性指数以及物种丰富度指数之间存在线性相关关系,冗余分析结果则支持温度因子对系统发育多样性及丰富度影响更显著,温度可能是影响鹞落坪保护区传粉昆虫多样性的重要生态因子。
From October 2019 to October 2021,2551 insect pollinators were collected in the typical forest-agriculture ecotone of Yaoluoping Nature Reserve.92 species of pollinators were identified by morphology and DNA Barcoding,belonging to 73 genera,34 families and 4 orders,among which Apis cerana,Bombus trifasciatus,Eristalis cerealis and Pieris canidia were the dominant species.The results of species diversity analysis showed that transect I dominated by farmland had higher species diversity than transects II andⅢdominated by forests,because a variety of crops can provide better habitat and food source for pollinators,while transectⅢ,which was near a tourist area severely disturbed by human,had significantly lower diversity.In addition,19(Bio1-Bio19)environment factors were downloaded from WorldClim database to analyze the correlation between diversity(including species and phylogenetic diversity)and environmental factors.There was a linear correlation between 14 environmental factors(Bio1,Bio4-13,Bio16,Bio18-19)and diversity index(including phylogenetic diversity and species richness).The results of redundancy analysis supported that temperature factors had a more significant effect on phylogenetic diversity and richness.Temperature could be the key ecological factors influencing the diversity of pollinators in the reserve.
