Overview of Sampled Lakes, Yukon Flats National Wildlife Refuge This dataset is a single comma-delimited text file (.csv). Data include the name of lakes where sampling occurred, approximate geographic coordinates of each lake, historical dynamics of the lake, and indication of measurements taken at the lake.

Data include the name of lakes where samples were obtained, the historical dynamics of that lake, the sampled community type, and the dry mass of annual new growth. Shrub community measurements are a combination of understory mass from quadrat harvests and shrub stem mass derived from published allometric equations.

These samples were used to create a relationship between total carbon and organic carbon for samples which were only run for total carbon.

Data include multiple lakes that are defined as either stable or drying. Lake margin vegetation communities include graminoid, shrub, and forest. Sols are separated into organic and mineral layers. Microbial data includes different phospholipid fatty acids and soil enzyme activity data for multiple enzymes involved in C,N, and P cycling. Data also includes information on respiration rate constants (k) and labile substrate pool (Ao) from soil incubations.

Observations were collected along up to four 100-meter linear transects oriented perpendicular to the lakeshore. Eight cover classes were used, and the median % cover for each cover class is shown in the dataset. Separate percent cover observations were recorded for each of eight distinct plant community encountered along each transect. Community types were associated with one of three aggregate community types (Grass/Sedge, Shrub, and Forest) for analyses. The dataset also includes a column indicating whether...
