Data from: Heart rate during hyperphagia differs between two bear species

Daily mean heart rate of three asian black bears and four brown bearsHeart rate from three, free-ranging, female Asian black bears from Ashio, Japan and from four, free-ranging, female brown bears from Dalarna, Sweden. Data starts in mid May and ends in December. Object_ID is the unique ID of the bears. HeartRate is the daily mean heart rate in bpm GMT_date is the date for the mean heart rate. DenningDay is the day of the year the bear entered hibernation. BodyMass is the mass of the bear in kg. PrDenDay is the time difference of the GMT_date to the DenningDay in days. Species indicates the bear species.yradDataHyperphagia.txt

本数据集涵盖三只亚洲黑熊（Asian black bear）与四只棕熊（brown bear）的每日平均心率数据。数据来源于日本足尾地区的3只野外自由活动的雌性亚洲黑熊，以及瑞典达拉纳地区的4只野外自由活动的雌性棕熊，采集周期自5月中旬起，至同年12月结束。各字段说明如下：Object_ID为每只熊的唯一个体标识；HeartRate为以每分钟心跳次数（bpm）计量的每日平均心率；GMT_date为对应每日平均心率的观测日期；DenningDay为该熊进入冬眠的当年日序；BodyMass为熊的体重，单位为千克；PrDenDay为观测日期（GMT_date）与冬眠起始日（DenningDay）的天数差值；Species为熊的物种分类。数据文件名为yradDataHyperphagia.txt

背景概述

该数据集记录了三种亚洲黑熊和四种棕熊在过度摄食期（从5月中旬到12月）的每日平均心率数据，用于比较两种熊在冬眠前代谢率的差异。研究发现，亚洲黑熊在夏季心率较低，但在过度摄食期心率比棕熊高一倍，这反映了因食物类型（如硬果与浆果）和可用性差异导致的生理适应。数据集提供了详细的变量信息，包括心率、日期和冬眠日等，支持相关生态和生理研究。
