9322699 Lomolina The proposed study will provide important insights on two issues central to global efforts to conserve biodiversity, the effects of fragmentation and the potential benefits of corridors. These studies will determine the effects of fragmentation on biodiversity of mammals inhabiting old-growth forests of the Olympic Peninsula. We will use spatial analysis techniques to investigate how the structure of old-growth forest communities reflects differences amount species, forest fragments and surrounding landscapes. Subsequently, we will use these patterns to assess the importance of corridors and the habitat matrix, on the biodiversity of old-growth forest mammals, and landscape features which favor immigrations of forest mammals. %%% We will adopt a multiscale, or hierarchical approach in our attempt to assess the effects of fragmentation of old-growth forests. Field studies will employ a combination of livetrapping, sign (tracks, scats, etc.), habitat and camera surveys conducted in nine continuous forest sites, 30 fragments of old-growth forest, and 10 locations along corridors and within clearcuts. Resultant data will be subjected to Monte Carlo, regression and correlation analyses to test predictions regarding fragmentation and biodiversity. %%% The information we will provide on distribution patterns in the fragmented landscape of Olympic National Forest will facilitate efforts to manage these forests for mammals and dependent species such as spotted owls. This research also will provide general insights regarding forest fragmentation by serving as a rigorous case study that documents the effects of fragmentation and assesses the influence of key processes influencing biodiversity.

9322699 Lomolina拟议的研究将提供重要的见解，对两个问题的核心全球努力，以保护生物多样性，破碎化的影响和走廊的潜在利益。 这些研究将确定破碎化对居住在奥林匹克半岛原始森林的哺乳动物生物多样性的影响。 我们将使用空间分析技术来研究古老森林群落的结构如何反映物种数量，森林碎片和周围景观的差异。 随后，我们将使用这些模式来评估走廊和栖息地矩阵的重要性，对古老的森林哺乳动物的生物多样性，有利于森林哺乳动物移民的景观特征。 %我们将采用多尺度或分层方法来评估原始森林破碎化的影响。 实地研究将采用现场诱捕，标志（轨道，粪便等），在9个连续森林地点、30片原始森林和沿着走廊和皆伐地内的10个地点进行了生境和照相机调查。 将对所得数据进行蒙特卡罗、回归和相关性分析，以检验关于碎裂和生物多样性的预测。 我们将提供的关于奥林匹克国家森林破碎景观分布模式的信息将有助于为哺乳动物和斑点猫头鹰等依赖物种管理这些森林。 这项研究还将作为一项严谨的案例研究，记录森林破碎化的影响，并评估影响生物多样性的关键进程的影响，从而提供关于森林破碎化的一般性见解。
