98-13050McNaughtonContingent herbivore regulation of ecosystem processesThis research will study the way that large herbivores, ungulates, can interact with the physical environment, particularly soils, to create environments that can be nutritionally advantageous to themselves. Humans are an integral component of the research plan since it is proposed that pastoralist cattle herders in Africa, by penning livestock inside villages at night to avoid predators, cause a large injection of nutrients into a local area. The investigators propose that after the village moves these enriched areas become favored foraging areas for native herbivores, which both maintain them and expand their area. Dr. McNaughton will compare the fate of abandoned village plots on soils that are inherently nutrient-poor with others that are nutrient-rich. In addition, mineralization rates will be assayed on plots at various ages from abandonment. This research will provide insight into how humans in Africa interact with the ecosystems they inhabit.

[00:30 . 50]偶然食草动物对生态系统过程的调节本研究将研究大型食草动物，有蹄类动物，如何与物理环境，特别是土壤相互作用，以创造对自己有利的营养环境。人类是研究计划的一个组成部分，因为有人提出，非洲的牧民在晚上把牲畜关在村庄里以躲避捕食者，给当地地区注入了大量的营养物质。研究人员提出，在村庄迁移之后，这些丰富的地区成为原生食草动物的觅食区，它们既维持了它们，又扩大了它们的面积。麦克诺顿博士将比较那些被遗弃的村庄土地的命运，这些土地本身就缺乏营养，而其他土地则富含营养。此外，矿化率将在不同年龄的地块上进行分析。这项研究将深入了解非洲的人类如何与他们所居住的生态系统相互作用。
