摘要

掠食者对猎物有很大的影响。除了直接的致命影响,仅仅是捕食者的存在就会增加压力和警惕性,反映出猎物的行为和生理。这种影响在更脆弱的猎物个体中应该更强,这取决于性别和生殖状况等。我们研究了短期生理反应,作为代谢指标的CO 2产生的变化,以及未怀孕和怀孕的野田鼠的行为反应。岸田鼠是北方森林环境中常见的小型哺乳动物,是捕食者尤其是小型鼬类的主要猎物之一。最小的鼬鼠Mustela nivalis nivalis是田鼠专家,也是唯一可以进入田鼠隧道和巢穴的掠食者。此外,黄鼠狼,像所有的鼬科动物一样,有强烈的气味用于社会交流,黄鼠狼的气味可能被猎物个体用作风险增加的线索。我们模拟了捕食风险的增加,将最少的鼬鼠气味注射到一个开放流动的呼吸测量系统中,该系统容纳了怀孕或未怀孕的雌性银行田鼠。我们关注的是二氧化碳产生的即时和后应激反应以及女性行为的变化。我们发现,注入纯空气(“干扰”)或鼬鼠气味(“威胁”)同样增加了二氧化碳的产生。令人惊讶的是,未怀孕的雌性对压力的反应比怀孕的雌性更强烈,即二氧化碳的增加更高。黄鼠狼气味比注入空气更能增加雌性的活动。根据我们的预测,黄鼠狼气味消失后,怀孕和未怀孕的雌性在生理和行为参数上没有差异。与我们的预测相反,我们的结果显示,无害的空气扰动和危险的黄鼠狼提示的反应非常相似。然而,可能是在环境突然变化的情况下,无论其性质如何,短期警惕反应比代价更高的反掠食行为更好。

Is Fear a Factor in Voles? Short Term Physiological and Behavioural Response to Predation Stress
A predator has a large impact on its prey. Besides a direct lethal effect, mere predator presence can increase stress and vigilance reflecting on prey behaviour and physiology. Such an effect should be stronger in more vulnerable prey individuals, depending e.g. on sex and reproductive status. We studied the short-term physiological response, the change in CO 2 production as a measure of metabolism, and the behavioural response in non-pregnant and pregnant bank vole Myodes glareolus females. The bank vole is a common small mammal in boreal forest environments and one of the major prey species for predators, especially small mustelids. The least weasel Mustela nivalis nivalis is a vole specialist and the only predator which can enter the tunnels of voles and their nests. Furthermore, weasels, like all mustelids, have strong scents used in social communication, and weasel odour may be used as a cue of increased risk by prey individuals. We simulated an increase in predation risk by the injection of least weasel odour into an open-flow respirometry system housing either a pregnant or non-pregnant female bank vole. We focused on immediate and post-stress response in CO 2 production and changes in female behaviour. We found that injections of pure air ("disturbance") or of weasel odour ("threat") similarly increased CO 2 production. Surprisingly, non-pregnant females responded to stress more strongly than pregnant ones, i.e. the increase in CO 2 was higher. Weasel odour increased female activity more than the injection of air. According to our prediction, after the disappearance of weasel odour there were no differences in physiological or behavioural parameters between pregnant and non-pregnant females. Contrary to our prediction, our results showed quite similar response to harmless air disturbance and the risky weasel cue. However, it may be that in a situation of sudden change in environment, regardless of its nature, a short-term vigilance response is a better response than more costly antipredatory behaviours.

期刊介绍: The Open Ecology Journal is an open access online journal which embraces the trans-disciplinary nature of ecology, seeking to publish original research articles, reviews, letters and guest edited single topic issues representing important scientific progress from all areas of ecology and its linkages to other fields. The journal also focuses on the basic principles of the natural environment and its conservation. Contributions may be based on any taxa, natural or artificial environments, biodiversity, spatial scales, temporal scales, and methods that advance this multi-faceted and dynamic science. The Open Ecology Journal also considers empirical and theoretical studies that promote the construction of a broadly applicable conceptual framework or that present rigorous tests or novel applications of ecological theory.
