本研究旨在确定草食动物行为与生产者提示之间的关系。我们以溪流食草动物Glossosoma幼虫为研究对象，根据微藻的化学和视觉线索确定了它们的爬行方向。实验处理包括对照（无线索）、颗粒（化学线索和颗粒线索）和溶解（化学线索）微藻线索。将实验水样随机放置在y形通道的两侧，并确定食草动物的爬行方向。尽管食草动物向含有颗粒线索或溶解线索的手臂爬行，但它们更喜欢含有颗粒线索的手臂。这表明食草动物对颗粒（即漂浮的藻类细胞）和化学（藻类气味）线索都有良好的反应，颗粒线索对觅食更重要。在自然栖息地，食草动物发现来自生产者的线索，并改变自己的行为，以保持自上而下和自下而上的线索之间的平衡。
This study aimed to determine the association between herbivore behavior and cues from producers. We used stream grazer Glossosoma larvae and determined their crawling direction in relation to chemical and visual cues from microalgae. The experimental treatments included control (no cue), particulate (chemical and particulate cues), and dissolved (chemical cue) cues from microalgae. The experimental water samples were randomly placed into either arm of a Y-shaped channel, and the crawling direction of the grazers was determined. Although the grazers crawled toward the arm containing either particulate or dissolved cues, they preferred the arm with particulate cues. This suggested that grazers responded well to both particulate (i.e., drifting algal cells) and chemical (algal smell) cues, and that particulate cues were more important for foraging. In natural habitats, grazers detect cues from producers and change their behaviors to maintain a balance between top-down and bottom-up cues.
