Abstract

Aquatic prey have impressive abilities to extract information from a variety of chemical cues. For example, they can use the alarm cues released by wounded individuals during a predator attack to learn about predation risk, and they can also distinguish kin from non-kin individuals during interactions. However, it remains unclear whether animals can combine this information on predation risk with kin recognition of the particular individuals under threat. To examine how the relatedness of the individuals in alarm cue affects behaviour we used the self-fertilizing hermaphroditic mangrove rivulus (Kryptolebias marmoratus), in which lineages produce genetically identical offspring through selfing. We explored this in two populations that differ in their level of outcrossing. We measured activity before and after exposure to alarm cue made from individuals (either adults or embryos) from their own lineage or an unrelated lineage from the same population. Fish responded weakly to embryo alarm cues, but tended to reduce their activity more when the alarm cues were from an unrelated lineage compared to alarm cues from their own lineage, particularly in fish from the outcrossing population. In contrast, there was no effect of cue relatedness on the response to adult alarm cues but there was a strong population effect. Specifically, individuals from the outcrossing population tended to react more strongly to alarm cues compared to individuals from the predominantly selfing population. We discuss the potential roles of the major histocompatibility complex in cue detection, differences between adult vs embryo alarm cues in terms of concentration and information, and underlying differences among populations and genetic lineages in their production and detection of chemical cues. Whether this kin recognition offers adaptive benefits or is simply a consequence of being able to detect relatedness in living individuals would be an exciting area for future research.

自交脊椎动物对化学警报线索中亲缘关系的检测取决于产生警报线索的种群和生命阶段。
水生猎物从各种化学线索中提取信息的能力令人印象深刻。例如,它们可以利用捕食者攻击时受伤个体释放的警报信号来了解捕食风险,还可以在互动过程中区分亲缘和非亲缘个体。然而,动物能否将捕食风险信息与对特定受威胁个体的亲缘识别结合起来,目前仍不清楚。为了研究报警线索中个体的亲缘关系如何影响行为,我们使用了自交雌雄同体的红树林杓鹬(Kryptolebias marmoratus)。我们在两个外交程度不同的种群中对此进行了探索。我们测量了鱼类在接触来自其自身种系或来自同一种群的不相关种系的个体(成鱼或胚胎)发出的警报提示前后的活动。鱼类对胚胎报警线索的反应较弱,但当来自非亲缘种系的报警线索比来自本种系的报警线索时,鱼类的活动量往往会减少,尤其是来自杂交种群的鱼类。相反,线索的亲缘关系对成鱼对警报线索的反应没有影响,但存在强烈的种群效应。具体来说,与主要来自自交种群的个体相比,来自外交种群的个体倾向于对警报信号做出更强烈的反应。我们讨论了主要组织相容性复合体在线索检测中的潜在作用、成体与胚胎报警线索在浓度和信息方面的差异,以及不同种群和遗传系在产生和检测化学线索方面的潜在差异。这种亲属识别是否会带来适应性益处,或者仅仅是能够检测到活体亲缘关系的结果,这将是未来研究的一个令人兴奋的领域。

期刊介绍: Behavioural Processes is dedicated to the publication of high-quality original research on animal behaviour from any theoretical perspective. It welcomes contributions that consider animal behaviour from behavioural analytic, cognitive, ethological, ecological and evolutionary points of view. This list is not intended to be exhaustive, and papers that integrate theory and methodology across disciplines are particularly welcome.
