生态生态学生态生态学
微生物学微生物学
昆虫学昆虫学是一门学科.

背景情况:

侵入性物种对生态构成重大威胁.
小蜂巢甲虫 (SHB), *Aethina tumida*,是一种具有广泛饮食的入侵性害虫.
蜂蜜蜂在蜂群内外都能在多样化的食物来源上壮成长的能力,有助于其全球传播.

研究的目的:

研究饮食如何影响小蜂巢甲虫 (SHB) 的肠道微生物组.
确定关键的微生物共生体及其在SHB生物学中的作用.
了解SHB适应能力和侵入性成功的微生物基础.

主要方法:

使用香和蜂巢资源模拟蜂巢内和外部养条件.
在不同的饮食中量化和分析了与SHB相关的微生物群落.
用基因标记 *Snodgrassella alvi* 来评估其在SHB肠道中的作用和短暂性质.

主要成果:

与食香的蜂巢资源相比,食香的SHB表现出更高的微生物α多样性和更多的碳水化合物活性酶.
在食香和从蜂巢收集的SHB中观察到高的共生物变异 (β多样性).
蜜蜂共生体 *Snodgrassella alvi* 在SHB中被发现,但似乎是暂时的; *Kodamaea ohmeri* 被确定为主要的SHB开始.

结论:

饮食变化显著影响SHB微生物群.
由饮食驱动的微生物适应对SHB的侵入性成功和生态影响至关重要.

Mutation, Gene Flow, and Genetic Drift

Mutation, Gene Flow, and Genetic Drift

In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).
