概括

冠状的花朵颜色变化是由地理和季节性变化的授粉者偏好驱动的. 这支持花色多态 (FCP) 在不同的环境和开花时间.

科学领域:

生态生态学生态生态学
进化生物学进化生物学
植物学植物学

背景情况:

花色多态性 (FCP) 可以受到不同授粉者组成及其在环境梯度和季节的颜色偏好的影响.
冠状,一个地质植物,展示了FCP,种群以红色,紫色和白色开花,特别是在以色列,南部种群是红色的,北部种群是多态的.

研究的目的:

研究昆虫游客的地理和季节性流动以及它们在冠状中的颜色偏好.
测试假设授粉者颜色偏好从北方早期季节的非红色转移到南部晚季节的红色,与FCP模式保持一致.

主要方法:

在以色列北部,中部和南部建立了红色,紫色和白色Anemone coronaria花的实验阵列.
在两年内,昆虫游客的花色选择被记录在三个时间点 (季初,季中,季后) 上.

主要成果:

昆虫授粉者偏好在不同地点和时间点之间有很大的差异.
北部/中部地区的蜜蜂和在季节早期更喜欢紫色的花朵,而南部地区的甲虫在季节晚期更喜欢红色的花朵.
观察到的时空趋势表明,紫色的花在北方收到更多的季节早期访问,而红色的花在南方收到更多的季节后期访问,支持该研究的预测.

结论:

该研究的发现与冠状的花色多态 (FCP) 模式一致,由传粉者偏好的时空转变驱动.
冠状的多样化的传粉动物群可能有助于其在广泛的地理分布和延长的开花季节的繁殖成功.

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.

Types of Selection

Types of Selection

Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

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.

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.
