概括

本地苦鱼避免了最近引入的入侵性,这表明它们迅速适应新的威胁. 这种宿主-寄生虫相互作用凸显了本地物种如何在入侵前线识别和逃避入侵物种.

科学领域:

生态生态学生态生态学
进化生物学进化生物学
侵入性物种研究侵入性物种研究

背景情况:

非本地物种的传播受行为适应和物种相互作用的影响.
同时发生的持续时间在相互作用的物种之间形成局部的共同进化模式.
在过去的50年里,入侵性 (Sinanodonta woodiana) 已经蔓延到欧洲各地,与欧洲本土的苦鱼 (Rhodeus amarus) 相互作用.

研究的目的:

调查快速局部共同进化的作用在欧洲苦鱼对入侵性鱼 *Sinanodonta woodiana* 的宿主选择.
根据与*S. woodiana*种群同时出现的持续时间,测试关于苦鱼产卵偏好的假设.
为了确定苦可以识别和避免入侵宿主.

主要方法:

对四个欧洲苦种群的产卵偏好进行实验评估.
bitterling 对 *S. woodiana* 种群的反应进行比较,同时发生的持续时间各不相同 (5,17,40+年).
基于个体质量与群体身份的本地 *Anodonta anatina* 贝类的苦鱼选择的评估.

主要成果:

所有测试的苦种群都避免了S. woodiana从最近建立的种群 (5年).
无论是当地的共存还是个体的质量都没有影响苦鱼避免 *S. woodiana*.
比特林是根据个体质量而不是人口身份而优先选择的本地 *Anodonta anatina*.

结论:

欧洲本土的苦可以识别和避免入侵 * Sinanodonta woodiana * 在入侵前线的入侵.
这些发现表明本地物种对新入侵宿主的快速行为适应.
这种识别机制可能对本地物种的生存和入侵物种的传播至关重要.

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.

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.

Speciation Rates

Speciation Rates

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.

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.

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).
