Abstract: PI-PASTOR: Individual species of animals or plants can produce effects which are strongly manifest at the ecosystem or landscape level. The population dynamics of such organisms, or the elimination of such species, can have dramatic ecosystem impacts. Such an animal with such a strong ecological footprint is the moose. This project uses state-of-the-art tracking technology linked to a global positioning system (GPS) to study the effects of moose at Voyageurs National Park, MN. The project studies the energetic balance of individual moose, the effect of moose on plant species distribution, the animal's effects on soil nutrient cycling, and develops a simulation model to study foraging strategy of moose and the impact of moose on landscape patterns. This research is valuable because it links behavioral and population studies with ecosystem and landscape level responses. The interfaces between these disciplines often do not overlap, although the two-way interaction between population biology and ecosystems ecology is often acknowledged. Three components of the research are especially well formulated and planned. First, the animal tracking work provides the detail necessary to examine animal behavior, foraging strategy, and spatially-explicit landscape effects. Second, the simulation model quantifies the impacts of this large grazing animal and may find application with numerous other large herbivores. Third, the research addresses animal linkages to processes such as nutrient cycling and decomposition in addition to structural components of ecosystems such as plant community distributions.

摘要：PI-Pastor：动物或植物的个别物种可以产生在生态系统或景观水平上强烈表现的作用。这种生物的种群动态或消除这种物种的生态系统会产生巨大的影响。如此强大的生态足迹的动物就是驼鹿。该项目使用与全球定位系统（GPS）相关的最先进的跟踪技术来研究驼鹿在明尼苏达州航空公司国家公园的影响。该项目研究单个驼鹿的能量平衡，驼鹿对植物物种分布的影响，动物对土壤养分循环的影响，并开发了一个模拟模型，以研究驼鹿的觅食策略以及驼鹿对景观模式的影响。 这项研究很有价值，因为它将行为和人口研究与生态系统和景观水平的反应联系起来。尽管人口生物学与生态系统之间的双向相互作用经常被认可，但这些学科之间的界面通常不会重叠。该研究的三个组成部分尤其完善和计划。首先，动物跟踪工作提供了检查动物行为，觅食策略和空间阐明景观效应所需的细节。其次，模拟模型量化了这种大放牧动物的影响，并可能与许多其他大型草食动物一起使用。第三，除了生态系统（例如植物社区分布）的结构成分外，该研究还解决了与营养循环和分解等过程的动物联系。
