Hydroperiod influences tadpole growth and development in the endangered Littlejohn’s tree frog

The dataset includes observations on Litoria littlejohni tadpoles from Gosner stage 25-26 to Gosner stage 42, encompassing their larval development, environmental conditions, and metamorphosis-related measurements. Data were collected from wild populations within Jilliby State Forest on the New South Wales Central Coast, Australia. The experiment took place in controlled laboratory environments. The experiment commenced in December 2022 and lasted for 28 weeks until metamorphosis or the experiment's conclusion. Tadpoles were acclimated and maintained in captivity, subjected to three water level treatments: "Declining," "Constant Low," and "Constant High." Weekly measurements, health checks, and experimental manipulations were conducted using standard scientific tools, including vernier callipers, electronic digital scales, and a jump test setup. Water parameters were monitored regularly. Recorded parameters involve weekly measurements of snout-to-vent length (SVL), body mass, Gosner stage, and jump test distances for froglets post-metamorphosis.

本数据集包含利特尔约翰氏雨滨蛙（Litoria littlejohni）蝌蚪从戈斯内尔发育阶段（Gosner stage）25-26期至42期的观测数据，涵盖其幼体发育过程、环境条件及与变态相关的各项测量指标。数据采集自澳大利亚新南威尔士州中海岸地区吉利比州立森林的野生种群，实验在受控实验室环境中开展。实验于2022年12月启动，持续28周，直至受试个体完成变态或实验结束。受试蝌蚪经驯化后于人工饲养条件下培育，设置了三种水位处理组别："水位下降组"、"恒定低水位组"与"恒定高水位组"。每周均采用标准科学工具开展测量、健康检查及实验操作，所用工具包括游标卡尺、电子数字天平和跳跃测试装置。同时定期监测水体参数。本次记录的参数包括每周测定的吻肛长（snout-to-vent length, SVL）、体质量、戈斯内尔发育阶段，以及变态完成后幼蛙的跳跃测试距离。
