Soil Microbial Community Changes in Wooded Mountain Pastures due to Simulated Effects of Cattle Grazing (2007)

Kohler, Florian, Hamelin, Jérôme, Gillet, François, Gobat, Jean-Michel, Buttler, Alexandre

The effect of cattle activity on pastures can be subdivided into three categories of disturbances: herbage removal, dunging and trampling. The objective of this study was to assess separately or in...

Effect of cattle activities on gap colonization in mountain pastures (2007)

Kohler, Florian, Gillet, François, Gobat, Jean-Michel, Buttler, Alexandre
