Cattle influences gap dynamics in pastures in two ways: (1) by creating gaps and (2) by affecting the colonization process. This effect of cattle activity on gap revegetation can be subdivided in three main factors: herbage removal, trampling and dung and ...
The present logic of built environment dispersion appears incompatible with the concept of sustainable development. The peripheral expansion of cities is indeed leading to irrational use of ground, growing environmental impact and important infrastructure ...
Since the 1950s, the population of the Brown hare (Lepus europaeus) has dramatically decreased in Switzerland as well as in other European countries. According to the Swiss Ornithological Institute of Sempach, this animal is an adequate indicator of the st ...
Evaluation of aquifer yields with the conventional time- drawdown method is based on the assumption of Theisian or infinite radial flow (IRF) of ground water to a well. However, long-term aquifer yields are controlled by heterogeneities and boundary condit ...
Numerous studies have shown the neuroprotective and regenerative benefits of glial cell line-derived neurotrophic factor (GDNF) in animal models of PD. Brain delivery of GDNF can, however, be associated with limiting side-effects in both primates and PD pa ...
A simulation model with time-dependent hydraulic conductivity parameters was used to predict the effects of three different tillage practices: conventional tillage (CT), no-tillage (NT) and subsoiling tillage (ST) on the components of the soil water balanc ...
Global data sets of the stable carbon isotope composition of plant leaves, of CO2 in canopy air, and of CO2 in the background atmosphere were compiled and compared to results of a global vegetation model (BIOME4) that simulated, at these three scales, the ...
