项目摘要

Dissertation Research: Influence of natal habitat type on dispersal and habitat selection behavior of brush mice (Peromyscus boylii)PI: Judy Stamps and Karen E. MabryLandscapes are composed of a variety of different habitat types, and while some species may be found in more than one of these habitat types, individual animals may choose to move through or settle in a particular habitat type. Habitat variation is often assumed to affect the movement and settlement patterns of animals, but the potential influence of experience with a particular habitat type on dispersal and habitat selection behavior has been unexplored. Do animals born and reared in a habitat type tend to move through and/or settle in that habitat type (a phenomenon known as habitat preference induction, or HPI)? The goal of the proposed research is to determine the effects of habitat type variation and natal habitat type on the behavior of brush mice (Peromyscus boylii) as they leave their mother's home range, search for, and settle in a new home range. The proposed field study will use a combination of methods, including live-trapping and radio-tracking, to observe the movement and settlement behavior of naturally dispersing mice, and fluorescent powder tracking to follow the movements of mice that are experimentally translocated to different habitat types. Radio-tracking will be used to assess animals' responses to habitat types (large scale habitat variation), and fluorescent powder tracking will be used to determine how animals respond to features within a habitat type, such as downed trees (small scale habitat variation). This research has implications for conservation issues such as wildlife corridor design, ecological restoration, and the viability of animal populations living in human-altered habitats.

论文研究：纳塔尔地类型对布氏鼠扩散和生境选择行为的影响。MabryLandscapes由各种不同的栖息地类型组成，虽然有些物种可能会在这些栖息地类型中的一个以上找到，但个别动物可能会选择在特定的栖息地类型中移动或定居。栖息地的变化通常被认为会影响动物的运动和定居模式，但对扩散和栖息地选择行为的经验与特定的栖息地类型的潜在影响一直未被探索。在一种栖息地类型中出生和长大的动物是否倾向于在该栖息地类型中移动和/或定居（一种称为栖息地偏好诱导或HPI的现象）？拟议的研究的目标是确定栖息地类型的变化和纳塔尔的栖息地类型的行为刷鼠（Peromyscus boylii）的影响，因为他们离开他们的母亲的家庭范围，搜索，并解决在一个新的家庭范围。拟议的实地研究将结合使用多种方法，包括现场诱捕和无线电跟踪，以观察自然分散的小鼠的运动和定居行为，并使用荧光粉跟踪跟踪实验转移到不同栖息地类型的小鼠的运动。无线电跟踪将用于评估动物对栖息地类型的反应（大规模栖息地变化），荧光粉跟踪将用于确定动物如何对栖息地类型内的特征作出反应，例如倒下的树木（小规模栖息地变化）。这项研究对保护问题，如野生动物走廊设计，生态恢复和生活在人类改变栖息地的动物种群的生存能力有影响。
