Patterns and determinants of lichen abundance and diversity across a subarctic to arctic latitudinal gradient

Macrolichen abundance at the species level in 42 sites across a subarctic (56°N) to arctic (62°N) latitudinal gradient in Nunavik (Québec, Canada). Data was collected in the dominant vegetation types of six regions sampled along this gradient. Decsription of the variables included in the dataset. Va...

Summary:Macrolichen abundance at the species level in 42 sites across a subarctic (56°N) to arctic (62°N) latitudinal gradient in Nunavik (Québec, Canada). Data was collected in the dominant vegetation types of six regions sampled along this gradient. Decsription of the variables included in the dataset.
