Description
Summary:We conducted a field experiment in which small mammal density was manipulated at two locations (near Toolik, and Nome, Alaska) with three replicate sites at each location. The motivation for collecting this carbon dioxide (CO2) flux dataset was to understand and quantify the impact of the most abundant herbivores, small rodents (voles and lemmings) on tussock tundra vegetation community composition and canopy structure in the Arctic. In July of 2018, at each site we set up an 8 meter (m) x 8 m fenced exclosure with a 0.635 centimeter (cm) square mesh to prevent herbivore grazing and increase vegetation cover (Exclosure treatment (EX)), set up a 20 m x 20 m enclosure that was stocked with up to 4 voles from spring snowmelt through September in 2018 and 2019 (Press treatment (PR)), and identified an 8 m x 8 m unfenced control plot marked at each corner with pin flags at each site (Control (CT)). In 2019, at the Toolik sites only, we set up a 20 m x 20 m enclosure at each replicate site that was stocked with up ...
