概括

长鹿根据红嘴牛的警报调整警,在暴露于捕食者的群体中显示出更高的反应. 这突显了相互关系中的上下文依赖的沟通好处.

科学领域:

动物行为动物行为
跨物种的沟通跨物种的交流
生态生态学生态生态学

背景情况:

动物利用异种特异的警报呼叫来检测捕食者,但将其整合到警策略中还没有完全理解.
长鹿 (Giraffa spp.) 是一种长鹿. 它们依赖于早期威胁检测,并与发出警报的红牛 (Buphagus erythrorhynchus) 相结合.
长鹿在多大程度上解释了牛的叫声,如果响应因掠食风险暴露而有所不同,则尚不清楚.

研究的目的:

为了调查长鹿是否会调整警,以响应牛的报警呼叫.
为了确定先前接触掠食风险是否会影响长鹿对这些呼叫的反应.

主要方法:

在三种长鹿种群中进行了回放实验,这些长鹿种群存在着不同的捕食者.
声学分析检查了牛警报呼叫的结构特征.
警行为被记录并与电话演示和生态环境相关分析.

主要成果:

长鹿在掠食者居住的地区表现出较长的警时间,而不是在无掠食者区域.
牛警报声具有与紧急性相关的声学特征 (低声比噪声比).
警反应是由生态环境 (狮子的存在或缺失) 调节的,而不仅仅是呼叫结构.

结论:

红嘴牛作为哨兵,长鹿用他们的警报叫声作为上下文依赖的早期预警信号.
长鹿具有捕食者经验,对牛警报的敏感性增加.
作为对相互交流的反应,行为灵活性适应不同的掠夺压力.

关键词:

报警呼叫报警呼叫反掠食者的行为.语境互惠主义 (Contextual Mutualism) 是一种相互理解的观念.长鹿是一个长鹿.异种特异性的窃听偷偷地窃听一个牛,一个牛.警警警警的意思

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.

Optimal Foraging

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

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.

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.

Nonconscious Mimicry

Nonconscious Mimicry

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

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...
