Mohonk Preserve Amphibian and Water Quality Monitoring Dataset at 11 Vernal Pools from 1931-Present

"The Mohonk Preserve's Daniel Smiley Research Center has been monitoring species occupancy, reproductive success, and water quality of 11 vernal pools (Ski Loop, Bonticou, Terrace, Long Woodland Pool, Long Woodland Swamp, Oakwood, Sleepy Hollow, Hermits, North Mud Pond, Canaan, and Talus) on the Preserve each spring from April 1931 to May 2019 (present). This project aims to document changes in the reproductive behavior and phenology of amphibians and allow research access to historical, longitudinal records. The dataset is a paired record of amphibian occurence with environmental indicators spanning nearly 90 years of data collection. The dataset includes environmental conditions for the 730 sampling events associated with the species occurences with complete coverage air temperature and precipitation records and partial coverage for a variety of other weather and water quality measures. Species occurence data collection has included species identification and counts of live and dead adults, mated pairs, spermatophores, egg masses, juveniles, and tadpoles counts as well as a record of the level of frog calling. Weather conditions including precipitation, sky and wind codes; and water quality measurements including water temperature, pH, and depth. Collection of data was sporadic from 1931 - 1991 but has been collected consistently from 1991 to present. We also began monitoring dissolved oxygen, nitrate concentrations, and conductivity of the vernal pools using a YSI Sonde Professional Plus Instrument and turbidity using a turbidity tube in February 2018. The data collection is ongoing, as are digitization efforts, and the data package will receive periodic updates."

莫霍克保护区（Mohonk Preserve）丹尼尔·斯迈利研究中心（Daniel Smiley Research Center）自1931年4月至2019年5月（持续至今），于每年春季对保护区内的11个季节性池塘（vernal pools）开展长期监测，涉及的池塘包括Ski Loop、Bonticou、Terrace、Long Woodland Pool、Long Woodland Swamp、Oakwood、Sleepy Hollow、Hermits、North Mud Pond、Canaan及Talus。本项目的核心目标为记录两栖动物的繁殖行为与物候变化，并为相关研究开放历史纵向监测记录的访问渠道。本数据集为两栖动物出现记录与环境指标的配对数据集，涵盖近90年的野外采集数据。数据集包含与730次物种出现采样事件对应的环境条件数据，其中气温与降水记录完整，其余多种气象及水质指标存在部分缺失。物种出现数据的采集内容包括物种鉴定、成活与死亡成体数量、配对个体数量、精荚（spermatophores）、卵块、幼体与蝌蚪数量，以及蛙类鸣唱等级记录；环境指标涵盖气象与水质两类，气象数据包括降水量、天空状况与风力等级，水质数据包括水温、pH值与水深。1931年至1991年期间，数据采集为间断性开展；1991年至今则保持持续稳定的采集节奏。2018年2月起，研究团队新增使用YSI Sonde Professional Plus型仪器监测季节性池塘的溶解氧、硝酸盐浓度与电导率，并采用浊度管监测浊度。目前数据采集与数字化整理工作仍在持续推进，数据集将定期进行更新。
