Effects of Sheep Grazing on Availability and Leaching of Soil Nitrogen in Low-Alpine Grasslands
(Journal article; Peer reviewed, 2012)Alpine ecosystems are generally nitrogen (N) limited with low rates of N mineralization. Herbivory may affect N cycling and N losses and thus long-term productivity of ecosystems. Using a controlled grazing experiment in ... -
Experimental effects of herbivore density on above-ground plant biomass in an alpine grassland ecosystem
(Journal article; Peer reviewed, 2014)Herbivores may increase or decrease aboveground plant productivity depending on factors such as herbivore density and habitat productivity. The grazing optimization hypothesis predicts a peak in plant production at ... -
The Response of Alpine Salix Shrubs to Long-Term Browsing Varies with Elevation and Herbivore Density
(Journal article; Peer reviewed, 2013)The widespread expansion of shrubs into arctic and alpine regions has frequently been linked to climatic warming, but herbivory can play a role in addition to, or in interaction with, climate. Willow (Salix spp.) shrubs ...
