Data from "Removal of grazers alters the response of tundra soil carbon to warming and enhanced nitrogen availability", Ecological Monograps in October 2019

Here we present the data used in the manuscript "Removal of
grazers alters the response of tundra soil carbon to warming and enhanced
nitrogen availability", Ecological Monograps, Early view in October
2019 by H. Ylänne, E. Kaarlejärvi, M. Väisänen, M. K. Männistö, S. H. K.
Ahonen, J. Olofsson & S. Stark. In this paper we studied,
how five years of experimental warming and increased soil
nitrogen availability interact with both long- and short-term differences
in grazing intensity in shaping ecosystem carbon stocks and the processes
underlying the changes. We used an over 50-year-old reindeer fence that
separates a lightly grazed shrub-dominated tundra from a heavily grazed
graminoid-dominated tundra, where the different grazing histories on the
two sides of the fences have created different ecosystem states. In
addition to the long-term grazing difference, we also established
short-term grazer exclosures on the heavily grazed side of the fence to
account for the effect of a sudden grazing cessation. This
file includes data of ecosystem carbon stocks, soil properties,
and fungal and bacterial copy numbers. It also provides data on
development of the vegetation through the course of the experiment
(2010-2014) and presents the activities of six extracellular
enzymes measured on three occasions in 2013.
