A list with two datasets containing presence-absence and environmental data for a plant community of sagebrush steppe in Dubois, Idaho, USA
A list with 2 dataframes, one corresponding to the presence-absence data and the other to the environmental variables. The first dataframe has in columns:
Name of the quadrat surveyed
Name of the species found
Several columns with the year in which the surveys were conducted
The second dataframe has the following columns:
Year in which surveys were conducted
Data of the recorded environmental variables in the form XXX.YYY, where XXX denotes a month (or a total) and YYY can refer to snow (in inches), temperature (fahrenheit degrees) or precipitation (in inches)
A historical dataset consisting of a series of permanent 1-m^2 quadrats located on the sagebrush steppe in eastern Idaho, USA, between 1923 and 1973. It also contains records of monthly precipitation, mean temperature and snowfall. Total precipitation, total snowfall, and mean annual temperature have been calculated from the original data.
Only quadrats Q1, Q2, Q3, Q4, Q5, Q6, Q25 and Q26 are included here. The surveys were conducted annually from 1932 to 1955 with some gaps for the quadrats included here.
