The stress gradient hypothesis predicts that competition will be important in productive environments while facilitation will be common in environments with high stress or consumer pressure. However, abiotic stress and grazing may vary independently and even occur simultaneously. Here we examine the outcome of plant interactions in grazed wetlands where consumer pressure and abiotic stress occur concurrently. We hypothesized that cattle grazing and microhabitat would alter the outcome of plant interactions. Given that wetland edges are drier and less productive than wetland centers we expected that facilitation would be greatest in drier wetland edges due to greater abiotic stress regardless of cattle presence.

放牧和微生境相互作用影响亚热带季节性湿地中的植物间相互作用

压力梯度假设预测，竞争在生产环境中将很重要，而便利化在压力或消费者压力较大的环境中将很普遍。但是，非生物胁迫和放牧可能会独立变化，甚至会同时发生。在这里，我们研究了放牧湿地中植物相互作用的结果，那里的消费者压力和非生物胁迫同时发生。我们假设放牧和微生境的牛会改变植物相互作用的结果。鉴于湿地边缘比湿地中心更干燥且生产力较低，我们预计，由于更大的非生物胁迫，无论牛身在何处，对干湿地边缘的促进作用最大。
