为了研究二氧化硅作为抗草食动物防御的重要性，两个雀麦草水培生长控制二氧化硅，氮，磷，钾含量，随后提供给草原田鼠，Microtus ochrogaster，在食物选择实验。喂食实验使用了两种设计。在第一个设计中，向田鼠提供了一种具有中等二氧化硅含量的标准草和另一种具有高或低二氧化硅和氮含量的草的选择。在第二个设计中，田鼠被提供了八种成对的草组合之一。在这两个实验中，田鼠消耗的高二氧化硅含量的草较少，这表明二氧化硅对哺乳动物食草动物起着有效的威慑作用。
To study the importance of silica as an anti-herbivore defense, two brome grasses were grown hydroponically to control silica, nitrogen, phosphorus, and potassium content and subsequently offered to the prairie vole, Microtus ochrogaster, in food choice experiments. Feeding experiments used two designs. In the first design, voles were presented a choice of a standard grass having intermediate silica content, and another grass with high or low silica and nitrogen content. In the second design, voles were presented with one of eight pairwise combinations of grasses. Voles consumed less grass of high silica content in both experiments, suggesting that silica acts as an effective deterrent to mammalian herbivores.
