Year to year activity and location data from a population of neighbouring Sleepy Lizards (Tiliqua rugosa)

Repository ContentThis repository contains records of neighbouring lizard's activity data from 2008 - current. Sleepy lizards have an activity period concentrated from spring to late summer and therefore the data were collected, on a year to year basis, as follows:- September 2008 - February 2009- September 2009 - December 2009- September 2010 - December 2010- Proposed - September 2011 - December 2011- Proposed - September 2012 - December 2012Data for 40 lizards were collected from September 2008 - February 2009, while data for 60 lizards were collected in all other years. The records are uploaded to the repository each year after each field season is complete. Lizards are neighbouring within an approximate 1 x 1.5km study site. Data are collected from the same lizards, at the same study site each year, however, from year to year, some lizards are unable to be relocated and so the composition of the sampled lizards may vary within a given year. Each lizard is identified by a unique number, displayed in the file name. For example, GPS_12138_2009, represents the activity data for lizard 12138 over the 2009 field season.Data Collection Methods and DetailsActivity data are collected by attaching a 'lizard logger' to the lizard's tails with surgical adhesive tape. These lizard loggers record temperature and number of steps taken every 2 minutes and a GPS location (Easting, Northing) every 10 minutes, if the lizard had moved in the previous 10 minutes. Each lizard was relocated every 12-14 days. Then lizard activity data from the past 12 days were downloaded from the lizard logger.GPS Data QualityThe precision of each GPS location varies according to the number of available satellite vehicles. In cases that included a GPS location, the lizard logger also recorded an estimated GPS location error, plus the date and time that the point was taken. Raw data in full GPS records consisted of: temperature (Celsius), step count, date (ddmm), Coordinated Universal Time (UTC) (hhmmss), Universal Transverse Mercator coordinate system (UTM) Easting (m), UTM Northing (m), Navigational Status (NF=No Fix, DR=Dead Reckoning, G2=Good fix 2D, G3=Good fix 3D), Horizontal Accuracy (m), 2D Horizontal Dilution of Precision, GPS Satellite Vehicle count. GPS locations were all taken in UTM zone 54.Step Count Data QualitySteps were counted by fastening a cylindrical magnet with superglue to the back of the lizards thigh, which connected to a reed switch on the corresponding place on the lizards tail. Occasionally the reed switch moved out of place under the surgical tape and therefore that unit did not accurately count steps at that time. As a consequence, sometimes lizard loggers may underestimate step counts. Each time a lizard was relocated every 12 days, we tested the number of steps the lizard logger recorded by connecting the reed switch to a multimeter while placing the lizard on the ground and encouraging it to take 30 steps. The number of steps that the reed switch counted per 30 real lizard steps was recorded and is included in the field notes for each time the lizard data were downloaded. If the reed switch was not accurately counting steps, it was repositioned and rechecked at the time the lizard was released.Additional information in Field NotesUpon handling each 12 days, each lizard was measured (snout to vent length: SVL) weighed and assessed for the number of scales that were damaged on the head, and the torso. Lizards were also assessed for the number of ectoparasites (ticks), however ticks were added and removed in another experiment throughout different years of study and therefore may fluctuate accordingly. Information on SVL, weight, scale damage and parasite load is located in the field notes.All methods were approved by the Flinders University Animal Welfare Committee.Date coverage: 2008 - 2010Location: Near Mount Mary, South Australia, Australia

本仓库收录了自2008年至今邻接蜥蜴活动数据的记录。昏睡状态下的蜥蜴活动期集中于春季至夏末，因此数据收集按年度进行，具体如下：
- 2008年9月至2009年2月
- 2009年9月至2009年12月
- 2010年9月至2010年12月
- 预计 - 2011年9月至2011年12月
- 预计 - 2012年9月至2012年12月
2008年9月至2009年2月收集了40只蜥蜴的数据，而在其他所有年份收集了60只蜥蜴的数据。记录每年在野外季节结束后上传至仓库。蜥蜴在约1 x 1.5公里的研究区域内相邻。数据每年从同一研究区域内的同一蜥蜴身上收集，然而，由于某些蜥蜴在年度间无法重新定位，因此样本蜥蜴的组成在特定年份内可能有所变化。每只蜥蜴都通过文件名中显示的唯一编号进行识别。例如，GPS_12138_2009表示12138号蜥蜴在2009年野外季节的活动数据。
数据收集方法和细节
活动数据通过将‘蜥蜴记录仪’用外科粘合带固定在蜥蜴尾巴上而收集。这些蜥蜴记录仪每2分钟记录一次温度和步数，每10分钟记录一次GPS位置（经度，纬度），如果蜥蜴在过去的10分钟内移动过。每只蜥蜴每12-14天重新定位一次。然后从蜥蜴记录仪中下载过去12天的蜥蜴活动数据。
GPS数据质量
每个GPS位置的精度根据可用卫星车的数量而变化。在包含GPS位置的情况下，蜥蜴记录仪还记录了估计的GPS位置误差、记录点的日期和时间。完整的GPS记录中的原始数据包括：温度（摄氏度）、步数、日期（ddmm）、协调世界时（UTC）（hhmmss）、通用横墨卡托坐标系（UTM）的东经（米）、北纬（米）、导航状态（NF=无定位，DR=失效航位推算，G2=良好定位2D，G3=良好定位3D）、水平精度（米）、2D水平精度衰减、GPS卫星车辆计数。GPS位置均取自UTM区54。
步数数据质量
步数通过将圆柱形磁铁用超级胶粘合在蜥蜴大腿背部，并将其连接到蜥蜴尾巴相应位置的簧片开关来计数。偶尔，簧片开关在手术胶带下移位，因此该装置当时无法准确计数步数。因此，蜥蜴记录仪有时可能会低估步数。每次蜥蜴每12天重新定位时，我们通过将簧片开关连接到万用表，将蜥蜴放在地上并鼓励它走30步来测试蜥蜴记录仪记录的步数。记录了簧片开关每30步实际蜥蜴步数所计的步数，并包含在每次下载蜥蜴数据时的现场笔记中。如果簧片开关未能准确计数步数，则在释放蜥蜴时将其重新定位并重新检查。
现场笔记中的其他信息
每12天处理一次蜥蜴时，测量（吻端至肛端长度：SVL）、称重，并评估头部和躯体的鳞片损伤数量。蜥蜴还被评估了体外寄生虫（蜱虫）的数量，然而，蜱虫在不同年份的研究中添加和移除，因此其数量可能会有所波动。SVL、体重、鳞片损伤和寄生虫负载的信息位于现场笔记中。
