人类引起的环境变化将对生物体产生重大的非致命和间接影响，因为改变了感觉通路，并对生态相互作用产生影响。虽然越来越多的工作致力于解决全球海洋变化如何损害生物体获取和使用信息来指导其行为的方式，但这些努力通常集中在路径的一个步骤（例如，接收提示/信号），一种感觉方式（例如视觉）或一个环境因素（例如温度）。为了更好地预测对海洋生态系统的更广泛影响，需要对环境变化的各个方面将如何影响多个感官途径以及因此产生的生态过程采取综合观点。在这里，我们提出了一个概念性的综合全球变化对海洋感官生态的影响，基于文献综述。我们的审查支持几个预测如何特定的感觉通路步骤-生产，传输和接收/处理的线索/信号-受到环境变化的影响。首先，生产和接收/处理的多种形式的线索/信号是脆弱的多个全球变化的压力源，这表明有概括的机制，环境变化损害这些途径的步骤，导致改变感觉通路的结果。增强生物体压力的因素可能会放大对这些感觉通路的影响。第二，全球变化因素往往会影响特定的线索/信号传输方式。因此，与线索/信号传输相关的生态过程的局部影响将取决于存在的环境应激源和相应的感觉方式。最后，由于许多生态和进化的相互作用依赖于感觉处理，感觉通路的损害可能经常支持全球海洋变化对海洋生态系统的影响。对个体感觉过程的影响将整合到交配，捕食和栖息地选择等形状过程中，我们强调了新的见解，采用我们的机械概念框架的影响生态相互作用。
Human-caused environmental change will have significant non-lethal and indirect impacts on organisms due to altered sensory pathways, with consequences for ecological interactions. While a growing body of work addresses how global ocean change can impair the way organisms obtain and use information to direct their behavior, these efforts have typically focused on one step of the pathway (e.g. reception of a cue/signal), one sensory modality (e.g. visual), or one environmental factor (e.g. temperature). An integrated view of how aspects of environmental change will impact multiple sensory pathways and consequently ecological processes is needed to better anticipate broader consequences for marine ecosystems. Here, we present a conceptual synthesis of effects of global change on marine sensory ecology, based on a literature review. Our review supports several predictions for how particular sensory pathway steps – production, transmission, and reception/processing of cues/signals - are affected by environmental change. First, the production and reception/processing of multiple modalities of cues/signals are vulnerable to multiple global change stressors, indicating that there are generalizable mechanisms by which environmental change impairs these pathways steps, leading to altered sensory pathway outcomes. Factors that enhance organismal stress as a whole may amplify impacts to these sensory pathways. Second, global change factors tend to affect specific modalities of cue/signal transmission. Consequently, local impacts on ecological processes linked with cue/signal transmission will vary depending on environmental stressor(s) present and the corresponding sensory modality. Finally, because many ecological and evolutionary interactions rely on sensory processing, impairment of sensory pathways may frequently underpin impacts of global ocean change on marine ecosystems. Effects on individual sensory processes will integrate to shape processes like mating, predation, and habitat selection, and we highlight new insights on impacts to ecological interactions by employing our mechanistic conceptual framework.
