SGER: Consequences of Large-scale Fire on Plant Reestablishment in Yellowstone National Park, Wyoming

1988年烧毁黄石国家公园的大火 一个独特的机会来调查生态反应， 大规模的干扰。火灾的一个显著特征是 导致烧毁景观的异质性， 无论是整体燃烧模式和可变的火灾严重性 在被烧毁的地区。 很少有生态学研究涉及 明确地与空间变化的干扰效果， 系统化、定量化。 之前的研究表明 物种对干扰的反应不仅在 与湿度、温度和其他环境的关系 梯度，但也与大小，形状和异质性， 不安的网站1988年的大火为我们提供了一个独特的机会， 生态学家研究植物重建后，大规模 火灾 罗姆，特纳和加德纳医生将评估 火灾形成斑块的大小和空间模式的重要性 在黄石公园的景观中重建植物物种 代表不同的繁殖模式。 调查人员 假设植物重建的速度 在一定程度上受地形的几何形状控制， 景观结构的相对重要性与 植物的繁殖方式。 这些调查人员都是该领域的高素质专家 景观生态学。对这项研究的机构支持 非常出色

The 1988 fires that burned Yellowstone National Park present a unique opportunity to investigate ecological responses to large-scale disturbance. A striking feature of the fires was the resulting heterogeneity of the burned landscape, in terms of both the overall burning patterns and the variable fire severity within the burned areas. Few ecological studies have dealt explicitly with the spatial variation of disturbance effects in a systematic and quantitative way. And previous research suggests that species' responses to disturbance may vary not only in relation to moisture, temperature, and other environmental gradients, but also with the size, shape, and heterogeneity of disturbed sites. The 1988 fires present a unique opportunity for ecologists to study plant reestablishment following large-scale fires. Drs. Romme, Turner and Gardner will evaluate the relative importance of size and spatial patterning of fire-created patches in the Yellowstone landscape for reestablishment of plant species representing different modes of reproduction. The investigators hypothesize that the rates of plant reestablishment are controlled in part by the geometry of the landscape, but that the relative importance of landscape structure differs with the plant's mode of reproduction. These investigators are highly qualified experts in the area of landscape ecology. The institutional support for this research is outstanding.
