概括

农业的强化损害了授粉者健康和授粉服务. 熊蜂比移动虫更容易受到伤害,由于体型减小和土地使用强度增加,它们面临着农作物授粉的风险.

科学领域:

生态生态学生态生态学
农业农业农业农业
昆虫学昆虫学是一门学科.

背景情况:

农业管理实践对昆虫授粉者产生重大影响,这些昆虫对作物生产和生物多样性至关重要.
授粉者健康受到当地和景观规模的各种因素的影响,影响授粉服务.
这些因素对不同授粉者群体的差异性影响仍未得到充分研究.

研究的目的:

调查土地使用强度,授粉者健康和熊蜂 (Bombus lapidarius) 和 (Episyrphus balteatus) 授粉服务之间的联系.
为了比较领土大黄蜂与迁徙蝶的脆弱性,在地方和景观层面上对土地利用的强化进行了比较.

主要方法:

利用来自德国生物多样性探索中心的数据,这是一个长期生物多样性研究平台.
测量特征作为授粉者健康 (例如体型,病毒感染,皮质谱) 和授粉服务的代理.
分析了当地/景观土地利用和气候因素对选定的授粉物种的影响.

主要成果:

土地使用强度和气候因素影响着授粉者健康,主要是通过身体尺寸的变化.
高土地使用强度减少了大黄蜂的身体尺寸;较高的温度减少了飞的身体尺寸.
在两种物种中,景观层面的强化土地利用减少了病毒感染.
土地利用的强化通过花朵覆盖和身体大小间接地对大黄蜂授粉服务产生了负面影响.
两种物种的授粉服务与身体大小相关.

结论:

由于不同的生命历史和移动性,大黄蜂比更容易受到土地利用强化的影响.
授粉者健康是授粉服务的关键媒介,突出了对农业的风险.
土地利用的强化对依赖以较小家庭范围的授粉者为依赖的作物构成重大风险.

Pollination and Flower Structure

Pollination and Flower Structure

Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.

Biodiversity and Human Values

Biodiversity and Human Values

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Dimensions of Health and Illness

Dimensions of Health and Illness

The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

What are Populations and Communities?

What are Populations and Communities?

Frequency-dependent Selection

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Predator-Prey Interactions

Predator-Prey Interactions

Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.
