Ecological Interactions Across Ecotones

一个生态群落通常被定义为 物种在特定的栖息地，与营养相互作用，这些 以静态食物网为代表的物种。 大多数社区， 然而，并不是与邻近地区物种的影响隔离开来的。 栖息地和个体可以改变它们在食物中的位置 在栖息地之间移动或移动，因为它们改变了身体大小。 这 该奖项侧重于发生在栖息地之间的相互作用 边界，利用对自然种群的观察， 对栖息地边界的实验性操纵， 在人工栖息地，以估计相互作用的重要性 溪流和伍德兰社区成员之间的关系。 研究 侧重于蝾螈的资源和相互作用， 蝾螈种群，它测试了生态理论， 维护复杂的生命周期和模型交互 人口规模结构之间的关系以及 景观生态学中群落间的相互作用。 研究 物种之间在栖息地边界的相互作用是很重要的 为了了解栖息地破碎化的后果， 这是由于土地使用模式的转变。

An Ecological community is usually defined as an assemblage of species in a given habitat, with trophic interactions among these species represented by a static food web. Most communities, however are not isolated from the effects of species in adjacent habitats and individuals can change their position in the food web or move between habitats as they change body size. This award focuses on interactions that take place across habitat boundaries, using observations of natural populations, experimental manipulation of habitat boundaries, and experiments in artificial habitats to estimate the importance of interactions between members of stream and wooodland communities. The study focuses on resources of salamanders and on interactions among salamander populations and it tests ecological theories on the maintenance of complex life cycles and models interactions between size-structured populations as well as the role of interactions between communities in landscape ecology. The study of interactions among species at habitat boundaries is important to understanding the consequences of habitat fragmentation that results from shifting land use patterns.
