Relationship between testosterone and movement patterns in male Asian black bear (<em>Ursus thibetanus</em>)

In male mammals, reproduction and reproductive behavior are strongly influenced by testosterone. While some species exhibit roaming behavior to encounter receptive females, and show consorting behavior with females, however, the relationship between sex hormone and those behaviors remains unclear. To clarify testosterone’s influence on behavior, we examined fecal testosterone metabolites (FTM) and behaviors in male Asian black bears (Ursus thibetanus) using collars equipped with GPS transmitters, activity sensors, and animal-borne cameras. We assessed four behavioral variables (daily movement speed, net movement distance, turning angle, activity level), and mating behavior in five males over a cumulative eight years. Fresh fecal samples, collected at GPS locations of collared individuals, were analyzed for FTM. In total, 111 feces were collected in 2022–2023 across 58 locations. The FTM values and the four behavioral variables were compared between the breeding (May–July) and post-breed..., , # Relationship between testosterone and movement patterns in male Asian black bear (*Ursus thibetanus*) Dataset DOI: [10.5061/dryad.pg4f4qs2k](10.5061/dryad.pg4f4qs2k) ## Description of the data and file structure The data to conduct analyses in the paper provide insight into the relationships between testosterone and behavior in male Asian black bears. ### Files and variables #### File: Base_data_frame.csv **Description:** This data frame is linked to the behavior variables for the fecal sample information. ##### Variables * Area: Study area * Bear_ID:  Identification of male bears that we studied * BID: Renamed “Bear_ID” as numeric * Point_ID: The location ID where we collected fecal samples * Scat_ID: The fecal sample ID * Year: Survey year * Month: Renamed months as numeric (May=5, June=6, July=7, August=8,September=9, October=10, November=11) * Duration: The duration is categorized for BS (Breeding season; May-1 to July-31), and NBS (Non-breeding season, as it is post-breed...,在雄性哺乳动物中，生殖活动与生殖行为均受睾酮的显著调控。尽管部分物种会通过漫游行为寻找处于发情期的雌性，并表现出与雌性交配伴行行为，但性激素与这类行为之间的关联仍未明确。为明确睾酮对行为的调控作用，本研究以雄性亚洲黑熊（*Ursus thibetanus*）为研究对象，借助搭载GPS发射器、活动传感器以及动物佩戴式相机的项圈，对其粪便睾酮代谢物（fecal testosterone metabolites, FTM）与行为展开分析。本研究在累计8年的周期内，对5只雄性个体的4项行为变量（日移动速度、净移动距离、转向角度、活动水平）以及交配行为进行了评估。研究人员在佩戴项圈个体的GPS定位点采集新鲜粪便样本，用于FTM检测。2022年至2023年间，研究人员共在58个采样点收集到111份粪便样本。本研究对繁殖期（5月—7月）与繁殖后期的FTM数值及4项行为变量进行了对比…… # 雄性亚洲黑熊（*Ursus thibetanus*）睾酮与活动模式的关联 数据集DOI：10.5061/dryad.pg4f4qs2k ## 数据与文件结构说明 本文用于分析的数据可用于揭示雄性亚洲黑熊睾酮与行为之间的关联。 ### 文件与变量 #### 文件：Base_data_frame.csv **说明：** 该数据框关联了粪便样本信息对应的行为变量。 ##### 变量 * Area：研究区域 * Bear_ID：本研究涉及的雄性黑熊个体标识 * BID：转换为数值型的"Bear_ID" * Point_ID：粪便样本采集点的位置ID * Scat_ID：粪便样本编号 * Year：调查年份 * Month：转换为数值型的月份（5月=5，6月=6，7月=7，8月=8，9月=9，10月=10，11月=11） * Duration：按繁殖季（BS，即繁殖期：5月1日至7月31日）与非繁殖季（NBS，即繁殖后时期）进行分类的时长……
