microhabitat selection by the Oscura Mountains Colorado chipmunk (Neotamias quadrivittatus oscuraensis): an old growth pinyon-juniper woodland specialist

Habitat specialists have been largely overlooked in old growth pinyon-juniper woodlands, despite specialists exhibiting heightened sensitivity to anthropogenic habitat loss. Furthermore, small mammal relationships within pinyon-juniper woodlands have most commonly been investigated via species abundance or habitat use, rather than habitat selection, thereby providing limited management metrics. We used the Oscura Mountains Colorado chipmunk (Neotamias quadrivittatus oscuraensis) as a model organism to evaluate whether old growth conditions drive resource selection by small mammals associated with pinyon-juniper woodlands. The goal of our study was to determine resources important to the chipmunk to inform management decisions. We evaluated microhabitat selection by testing a priori predictions based on natural history characteristics of the chipmunk and the woodlands. We grouped predictions into habitat characteristics affiliated with or not affiliated with old growth. We tested predict..., Habitat variables were collected in the field and from a geographic information system at locations where the Oscura Mountains Colorado Chipmunk was detected and at paired random sites., , # Microhabitat selection by the Oscura Mountains Colorado chipmunk (Neotamias quadrivittatus oscuraensis): an old growth pinyon-juniper woodland specialist

The dataset was used in the manuscript **Microhabitat selection by the Oscura Mountains Colorado chipmunk (*Neotamias quadrivittatus oscuraensis*): an old growth pinyon-juniper woodland specialist**, submitted to the Journal of Mammalogy

## Description of the data and file structure

The data are contained in an Excel file with two tabs. The first tab is a definition of the 129 variables grouped by hypotheses related to old growth woodland conditions (82 variables representing the 4 old growth habitat characteristics) and factors not related to old growth woodland conditions (47 variables representing 8 non-old growth habitat characteristics). The second tab contains the dataset including site names and variables. Data were collected in the field ...

尽管生境特化类群对人为生境丧失的敏感性更高，但成熟杜松-松木本群落（old growth pinyon-juniper woodlands）中的特化类群长期以来很大程度上被忽视。此外，以往针对杜松-松木本群落内小型哺乳动物关系的研究，大多通过物种丰度或生境利用展开，而非生境选择，因此可提供的管理参考指标极为有限。本研究以奥斯科拉山科罗拉多花鼠（Neotamias quadrivittatus oscuraensis，Oscura Mountains Colorado chipmunk）作为模式生物，探究成熟生境是否会驱动与杜松-松木本群落相关的小型哺乳动物的资源选择。本研究的目标是明确对该花鼠而言至关重要的资源，以期为管理决策提供依据。我们基于该花鼠的自然历史特征以及该木本群落的属性，提出先验假设并以此检验其微生境选择情况。我们将假设划分为与成熟生境相关的特征，以及与成熟生境无关的特征两类。我们对假设进行了检验…… 生境变量通过野外采集以及地理信息系统（Geographic Information System，GIS）获取，采集点位涵盖奥斯科拉山科罗拉多花鼠的发现位点以及配对随机样地。

## 数据与文件结构说明
本数据集存储于一个包含两个工作表的Excel文件中。第一个工作表为129个变量的定义表，这些变量按假设分组：一类是与成熟木本群落条件相关的变量（82个变量，对应4项成熟生境特征），另一类是与成熟木本群落条件无关的变量（47个变量，对应8项非成熟生境特征）。第二个工作表包含完整数据集，其中包含样地名称与各类变量信息。野外采集的数据……
