ABSTRACT:

This resource describes code for the temperature manipulation experiment in "Stream bryophytes promote “cryptic” productivity in highly oligotrophic headwaters" (Thellman et al. 2024). Water baths constructed from ~6" PVC pipes were warmed to approximately 2 degrees C above ambient stream temperature in the Spring of 2021 at Hubbard Brook Experimental Forest (HBEF). Operationally, the "warm" treatments were heated from an Arduino that turned on and off an aquarium heater to maintain temperatures above ambient. Ambient temperatures were also recorded from the Arduinos to an SD card. Approximately every 2 days the SD cards were downloaded for data. The aquarium heater was powered by a propane generator that ran for 2-3 weeks. Full methods and data are described in Thellman and others (2024).

ABSTRACT:

Data associated with the publication "High Potential but Low Achievement: Frequent disturbance contains the light use efficiency of river ecosystems." This data contains the subset of 64 rivers that have at least 6 years of data and more than 60% of their record for each year. It also contains data from publications that were used for figures in the manuscript.
