摘要

“花条”的概念是一种为传粉者提供更多不同食物来源的策略。在城市环境下,“同质”白花(Phacelia tanacetifolia)和“异质”(花混合)食物来源对大黄蜂(Bombus terrestris)和蜜蜂(Apis mellifera)酶活性的影响尚未见报道。众所周知,生物体对具有挑战性的环境条件的反应会表现出氧化应激参数的增加,这反过来又会影响生理和代谢参数。在德国柏林-达勒姆进行了一项实地研究,利用“标记”酶超氧化物歧化酶(SOD)对食物来源的反应进行评估。SOD数据也来自于野生蜜蜂Megachile rotundata (Fabricius 1787),该蜜蜂从德国勃兰登堡州的三个不同地点获得。结果表明,与白穗花相比,大黄蜂访问混合花时SOD酶活性显著增加。实验方法在物种水平上具有个体效应,分别是大黄蜂和蜜蜂。生物标志物SOD的活性可以成功地用于评价均匀和异质花田成分的影响。

Response of Superoxide Dismutase (SOD) to Homogeneous and Heterogeneous Food Sources in Bumblebees (Bombus terrestris) and Honeybees (Apis mellifera)
The conception of “floral strips” is a strategy to provide more and different food sources for pollinators. The impact of “homogeneous” Phacelia tanacetifolia (“Phacelia”) and “heterogeneous” (flower mix) food sources on the enzyme activity of bumblebees (Bombus terrestris) and honeybees (Apis mellifera) under urban conditions has not been reported. Organisms responding to challenging environmental conditions are known to exhibit increases in oxidative stress parameters which in turn affect both physiological and metabolic parameters. A field study was conducted in Berlin-Dahlem, Germany, using the response of the “marker” enzyme superoxide dismutase (SOD) on food sources for assessment. SOD data is also shown from the wild bee Megachile rotundata (Fabricius 1787), obtained from three different locations in the federal state Brandenburg, Germany. The results demonstrate that the enzyme activity of SOD significantly increased in bumblebees visiting the flower mix compared to the Phacelia. The experimental approach had individual effects at the level of the species, bumblebees and honeybees, respectively. The activity of the biomarker SOD could be successfully used to assess the effects of the compositions of homogeneous and heterogeneous flower fields.
