Earthworm communities in alluvial forests : Influence of altitude, vegetation stages and soil parameters

Salomé, Clémence ; Guenat, Claire ; Bullinger-Weber, Géraldine ; Gobat, Jean-Michel ; Le Bayon, Renée-Claire

In: Pedobiologia, 2011, vol. 54S, p. S89-S98

In many terrestrial ecosystems, soil parameters usually regulate the distribution of earthworm communities. In alluvial ecosystems, few studies have investigated the impact of periodic floods and alluvium deposition on soil fauna. In this context, we assumed that earthworm communities may vary depending on altitude (alpine, subalpine, mountain and hill levels), forest successional stage...

Discrepancies in Growth Measurement Methods of Mosses : An Example from Two Keystone Species Grown under Increased CO2 and N Supply in a Restored Peatland

Siegenthaler, Andy ; Buttler, Alexandre ; Grosvernier, Philippe ; Gobat, Jean-Michel ; Mitchell, Edward A. D

In: American Journal of Plant Sciences, 2014, vol. 5, no. 15, p. 2354-2371

Bryophytes dominate northern peatlands. Obtaining reliable measurements of moss-growth and how it may be affected by global changes are therefore important. Several methods have been used to measure moss-growth but it is unclear how comparable they are in different conditions and this uncertainty undermines comparisons among studies. In a field experiment we measured the growth and production of...

Review: From multi-scale conceptualization to a classification system for inland groundwater-dependent ecosystems

Bertrand, G ; Goldscheider, Nico ; Gobat, Jean-Michel ; Hunkeler, Daniel

In: Hydrogeology journal, 2012, vol. 20, p. 5-25

Aquifers provide water, nutrients and energy with various patterns for many aquatic and terrestrial ecosystems. Groundwater-dependent ecosystems (GDEs) are increasingly recognized for their ecological and socio-economic values. The current knowledge of the processes governing the ecohydrological functioning of inland GDEs is reviewed, in order to assess the key drivers constraining their...
