Contrasting effects of reindeer grazing on CO 2 , CH 4 , and N 2 O fluxes originating from the northern boreal forest floor
Abstract Reindeer ( Rangifer tarandus L.) is considered to be an important mammalian herbivore, strongly influencing Arctic lichen‐dominated ecosystems. There is no wide knowledge about the effect of reindeer on greenhouse gas (GHG) fluxes in northern boreal forests. Ground vegetation plays an impor...
