DEB-9615887 SOUSA Herbivores may influence plant community composition and the impact of herbivores may vary spatially. Despite considerable conceptual interest, this hypothesis has been tested in few natural communities. The investigators propose to examine the affect of insect herbivores on the distribution of mangrove species along a tidal gradient. They will conduct experiments to measure the impact of the herbivores on growth and survival of plants in gaps versus under a closed canopy and in intertidal zones. This experiment is specifically designed to detect spatial variation in the effect of herbivory on plant competition and will complement existing mangrove competition experiments at the same field site. Mangrove forests are being degraded and destroyed at an alarming rate worldwide, resulting in the loss of highly productive ecosystems that have numerous ecological, economic, and aesthetic values. The results of this project will have considerable value in predicting the consequences of different human-caused alterations of these endangered wetlands and in guiding efforts to restore mangrove communities.

DEB-9615887 SOUSA 食草动物可能会影响植物群落的组成和食草动物的影响可能会有所不同的空间。 尽管有相当多的概念兴趣，这一假设已经在少数自然群落中得到了检验。 调查人员建议研究昆虫食草动物对沿着潮汐梯度分布的红树林物种的影响。 他们将进行实验，以测量草食动物对植物生长和生存的影响，在差距与封闭的树冠下和潮间带。 本实验是专门设计来检测空间变化的影响，植物竞争的草食动物，并将补充现有的红树林竞争实验在同一领域的网站。 红树林在世界范围内正以惊人的速度退化和破坏，导致具有众多生态、经济和美学价值的高产生态系统丧失。 该项目的结果将在预测这些濒危湿地的各种人为改变的后果和指导恢复红树林群落的努力方面具有相当大的价值。
