概括

城市温度会影响蚊子的生长和生存. 温暖的条件缩短了发育,但减少了成年人的生存率和翅膀大小,影响了疾病载体的能力.

科学领域:

环境科学环境科学
生态生态学生态生态学
载体生物学载体生物学

背景情况:

昆虫 (Culex pipiens sensu stricto (s.s.) 和昆虫 (Culex torrentium) 是欧洲Sindbis,Usutu和西尼罗河病毒的关键载体.
这些蚊子在人工水容器中繁殖,在城市环境中普遍存在,使它们成为重要的城市害虫和疾病载体.

研究的目的:

研究城市地区微气候变化的影响,对Culex pipiens s.s./Cx.的发展,生存和健康状况的影响. 这就是Torrentium.
评估温度和城市化梯度如何影响青少年发育,成人特征 (翅膀大小,不对称性) 和在热应激下生存.

主要方法:

在德国奥尔登堡 (2021-2022) 进行了一项半现场研究,使用城市化梯度沿线的45个人工息地.
幼虫发育,幼虫存活率,翅膀大小,翅膀不对称性和成人在热应激 (31°C) 下的存活率都被测量为Cx. 皮皮恩斯公司/Cx. 这就是Torrentium.

主要成果:

更高的城市化与更高的温度相关,导致蚊子发育时间缩短.
幼的最佳生存时间在20-21°C之间发生;较温暖的地点在热应激下减少了成人的生存时间,并减少了翅膀的大小.
较大的翅膀尺寸与较低的不对称性有关,但不对称性在更高的繁殖场温度下增加,表明环境压力.

结论:

城市地区的微气候异质性显著影响蚊子的发育和健康特征.
将微观气候数据纳入风险评估模型对于管理蚊子传播疾病至关重要.

Hybrid Zones

Hybrid Zones

Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

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.
