概括

侵入性巨型树脂蜂 (Megachile sculpturalis) 使用巢穴,并提供来自日本寺树的单花花粉的繁殖细胞. 这种行为可能会影响本地蜜蜂对资源的竞争.

科学领域:

生态生态学生态生态学
昆虫学昆虫学是一门学科.
侵入性物种生物学生物学

背景情况:

巨型树脂蜜蜂 (Megachile sculpturalis),原产于东南亚,已经在北美和欧洲建立了种群.
尽管它具有侵入性传播,但关于M. sculpturalis的筑巢行为和生物学的详细信息仍然有限.

研究的目的:

研究意大利博洛尼亚的入侵性巨型树脂蜜蜂 (Megachile sculpturalis) 的筑巢生物学和花粉供应.
为了描述M. sculpturalis使用的巢结构,腔径偏好和花粉来源.

主要方法:

在连续三年内观察人工中的筑巢行为.
测量巢穴直径和巢结构的特征.
对繁殖细胞中的花粉含量进行分析.

主要成果:

观察了166只蜜蜂和监测了41只母蜂;测量了552个巢,描述了100个.
首选的巢穴直径从0.6到1.2厘米不等,与本地物种重叠.
细胞被提供单花花粉,主要来自Styphnolobium japonicum (日本寺树).
据估计,需要180次花访,才能提供一个单一的繁殖细胞.

结论:

这项研究提供了关于入侵性Megachile sculpturalis的巢生物和巢结构的关键数据.
这些发现突出了与本土蜜蜂在筑巢地点和食资源方面的潜在竞争,特别是日本的寺树.

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.

Mate Choice

Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Keystone Species

Keystone Species

Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a...

Phylogeny

Phylogeny

Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.
