Rattus villosissimus - radio tracking dataset

This dataset contains radio-tracking information on the long-haired rats (Rattus villosissimus). Data was collected between October 2011 and December 2012. It contains the data from enclosure in which a radio-collared rat was released and tracked (Enclosure = 1 or 2), the treatment (Cats = yes or no), the exact date (Date) for when a rat was released with a collar (collared_released), the last time it was recorded (last-time-rec), the time period in months over which the collar frequency was detected (time-collar-detected), the fate of the animal (Fate = unknown, dead or alive), the last location change detected (last_loc_change), based on the latter, the estimated time a rat was assumed alive (estimated_time_alive), the last time a signal was detected from the collar (last_signal detected), the date of the last time an animal was trapped (last_trapped), whether dead remains were found (dead_remains_found = na, yes, or no) and whether the collar was found (collar_found = na, yes, or no).

本数据集包含长毛大鼠（Rattus villosissimus）的无线电追踪（radio-tracking）数据，采集时段为2011年10月至2012年12月。数据集涵盖以下信息：无线电项圈标记大鼠的放归与追踪围栏（围栏编号为1或2）、实验处理设置（是否存在猫，即Cats字段取值为是或否）、佩戴项圈大鼠的准确放归日期（"collared_released"，对应字段Date）、末次记录时间（"last-time-rec"）、项圈信号被探测到的时长（以月为单位，"time-collar-detected"）、动物存活结局（Fate字段取值为未知、死亡或存活）、末次探测到的位置变化（"last_loc_change"）、基于该变化估算的大鼠假定存活时长（"estimated_time_alive"）、末次探测到项圈信号的时间（"last_signal detected"）、末次诱捕到该动物的日期（"last_trapped"）、是否发现动物尸体残骸（"dead_remains_found"字段取值为无数据、是或否），以及是否回收项圈（"collar_found"字段取值为无数据、是或否）。
