动物信号的产生和结构可能取决于个人的健康状况，并且可能向接收者提供不止一种类型的信息。虽然警报通常不被视为依赖于健康状况，但最近的研究表明，警报的结构以及可能发出的倾向取决于个人的健康状况和状态。我们通过量化陷阱引发的和自然的鸣叫率作为中性粒细胞与淋巴细胞 (NL) 比率的函数、血源性锥虫的存在以及几种肠道寄生虫（艾美耳球虫属、内阿米巴属和蛔虫属）的存在，询问黄腹土拨鼠 (Marmota flavienter) 发出叫声的倾向是否受到其免疫或寄生虫状态的影响。我们拟合了混合效应模型，以确定我们收集的健康指标是否与陷阱发出警报的概率以及自然警报发出的年率相关。感染血源性锥虫的土拨鼠在被困时自然叫声的可能性稍高，而感染肠道寄生虫蛔虫的土拨鼠在被困时自然叫声的可能性较小。 NL 比率与陷阱内呼叫概率没有直接关系，但当雄性具有较高的 NL 比率时，它们更有可能呼叫。因此，寄生虫感染和免疫系统激活等健康状况可以调节警报信号的产生，并有可能向捕食者和猎物提供有关呼叫者状况的信息。需要进行回放实验来确认接收者是否使用此类信息。
The production and structure of animal signals may depend on an individual’s health status and may provide more than one type of information to receivers. While alarm calls are not typically viewed as health condition dependent, recent studies have suggested that their structure, and possibly their propensity to be emitted, depends on an individual’s health condition and state. We asked whether the propensity of yellow-bellied marmots (Marmota flaviventer) to emit calls is influenced by their immunological or parasite status, by quantifying both trap-elicited and natural calling rates as a function of their neutrophil-to-lymphocyte (NL) ratio, the presence of a blood borne trypanosome, and the presence of several intestinal parasites (Eimeria sp., Entamoeba sp., and Ascaris sp.). We fitted mixed effects models to determine if the health measures we collected were associated with the probability of calling in a trap and with annual rates of natural alarm calling. Marmots infected with a blood-borne trypanosome were marginally more likely to call naturally and when trapped, while those infected with the intestinal parasite Ascaris were less likely to call when trapped. NL ratio was not directly associated with in-trap calling probability, but males were more likely to call when they had higher NL ratios. Thus, health conditions, such as parasite infection and immune system activation, can modulate the production of alarm signals and potentially provide information to both predators and prey about the caller’s condition. Playback experiments are required to confirm if receivers use such information.
