Temperature-dependence of regional heterothermy in a diminutive ectotherm

Dataset describing variation in temperature between the head and the cloaca for ringnecked snakes (Diadophis punctatus) in the laboratory and in the field. SnakeID= unique ID assigned to each snake. CollectionDate= the date that snakes were collected and when field body temperatures were measured. Gravid=whether eggs were palpated in the abdomen of snakes, where 1=gravid and 0= not gravid. Ecdysis=whether snakes were close to the time when they would shed, assessed by the presence of opaque eye scales and shedding skin, where 1=ecdydic and 0=non-edcydic. Life stage= whether snakes were juveniles or adults, where A=adult and J=juvenile. SVL_mm=snout-vent length in mm. Mass_g=body mass in g. Scars=the presence of any visually detectable scars on the body, where 1= presence of scars and 0= no scars. Handling_time= the duration between capture and measurement of body temperature. Field_mouth= the temperature of the mouth as measured immediately after capture in the field. Field_cloaca=the temperature of the cloaca as measured immediately after capture in the field. 15_head= the temperature of the head measured after 1 h in an incubator at 15 degrees Celsius. 15_cloaca=the temperature of the cloaca after 1 h in an incubator at 15 degrees Celsius. 20_head= the temperature of the head measured after 1 h in an incubator at 20 degrees Celsius. 20_cloaca=the temperature of the cloaca after 1 h in an incubator at 20 degrees Celsius. 25_head= the temperature of the head measured after 1 h in an incubator at 25 degrees Celsius. 25_cloaca=the temperature of the cloaca after 1 h in an incubator at 25 degrees Celsius. 30_head= the temperature of the head measured after 1 h in an incubator at 30 degrees Celsius. 30_cloaca=the temperature of the cloaca after 1 h in an incubator at 30 degrees Celsius. 32_head= the temperature of the head measured after 1 h in an incubator at 32 degrees Celsius. 32_cloaca=the temperature of the cloaca after 1 h in an incubator at 32 degrees Celsius.

本数据集记录了环颈蛇（Diadophis punctatus）在实验室与野外环境中头部与泄殖腔的体温差异情况。各字段说明如下：
1. 蛇个体编号（SnakeID）：为每条环颈蛇分配的唯一识别码。
2. 采集日期（CollectionDate）：环颈蛇被捕获以及野外体温测量的日期。
3. 怀卵状态（Gravid）：通过腹部触诊判断蛇体内是否存在卵，其中1代表怀卵，0代表未怀卵。
4. 蜕皮状态（Ecdysis）：通过眼部鳞片浑浊程度以及蜕下的皮肤评估蛇是否临近蜕皮周期，其中1代表临近蜕皮，0代表未临近蜕皮。
5. 生活史阶段（Life stage）：区分环颈蛇为成体或幼体，其中A代表成体，J代表幼体。
6. 吻肛长（SVL_mm）：以毫米为单位的吻肛长度。
7. 体质量（Mass_g）：以克为单位的蛇体质量。
8. 伤痕状态（Scars）：体表是否存在肉眼可见的伤痕，其中1代表存在伤痕，0代表无伤痕。
9. 处理时长（Handling_time）：从捕获环颈蛇到完成体温测量之间的时间间隔。
10. 野外口腔体温（Field_mouth）：野外捕获环颈蛇后立即测量的口腔温度。
11. 野外泄殖腔体温（Field_cloaca）：野外捕获环颈蛇后立即测量的泄殖腔温度。
12. 15℃孵育头部体温（15_head）：将蛇放置于15℃恒温培养箱中孵育1小时后测量的头部温度。
13. 15℃孵育泄殖腔体温（15_cloaca）：将蛇放置于15℃恒温培养箱中孵育1小时后测量的泄殖腔温度。
14. 20℃孵育头部体温（20_head）：将蛇放置于20℃恒温培养箱中孵育1小时后测量的头部温度。
15. 20℃孵育泄殖腔体温（20_cloaca）：将蛇放置于20℃恒温培养箱中孵育1小时后测量的泄殖腔温度。
16. 25℃孵育头部体温（25_head）：将蛇放置于25℃恒温培养箱中孵育1小时后测量的头部温度。
17. 25℃孵育泄殖腔体温（25_cloaca）：将蛇放置于25℃恒温培养箱中孵育1小时后测量的泄殖腔温度。
