概括

在1926年至2017年期间,高飞的迁徙昆虫种群总体保持稳定. 然而,农业害虫的增加表明有益昆虫群落的减少,影响生态系统.

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.
保护生物学保护生物学

背景情况:

迁徙昆虫的减少日益令人担忧,但对高海拔迁徙昆虫群体的长期变化仍然不太了解.
由于它们的高空飞行模式和空中采样的劳动密集性,调查这些社区具有挑战性.
空中捕捉是识别物种和在高海拔地区采样较小昆虫的关键方法.

研究的目的:

分析高飞的迁徙昆虫的空中密度和社区结构的长期变化.
为了评估一个世纪以来不同大陆的迁徙昆虫种群的稳定性.
了解观察到的变化对生态系统功能和生物多样性保护的影响.

主要方法:

对欧洲,北美和亚洲 (1926年至2017年) 的历史空中捕获数据和高山网记录的综合分析.
在地面以上大约200米处对空中昆虫密度的定量评估.
对总体迁徙昆虫密度与特定农业害虫种群趋势的比较分析.

主要成果:

从1926年到2017年,欧洲,北美和亚洲的高空迁徙昆虫的总体空中密度保持相对稳定.
在研究期间,观察到某些迁徙农业害虫种群的显著增加.
这些发现表明,空中移民社区的非害虫组成部分的潜在下降.

结论:

虽然迁徙昆虫的总数似乎稳定,但社区组成的变化,特别是害虫的增加,表明了潜在的生态变化.
高海拔迁徙昆虫群落的变化与更广泛的大规模生态系统变化密切相关.
持续监测农业害虫和保护各种非害虫和有益的迁徙昆虫至关重要,以保持生态系统的健康.

Migration

Migration

Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

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).

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.

Gene Flow

Gene Flow

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.
