Ecology and EvolutionWe selected 15 sheep‐grazed sand pastures along a gradient of increasing grazing intensity to study the fine‐scale patterns of main biomass fractions (green biomass, litter) and that of plant species and functional groups (life forms and social behaviour

Aboveground Net Primary Productivity in Grazed and Ungrazed pastures: Grazing Optimisation Hypothesis or Local Extinction of Vegetation Species [PDF]
, 2009 The controversy that has surrounded herbivory studies in the last few decades prompted our investigation to establish the extent to which herbivore optimisation hypothesis or compensatory growth evidence is real.

Effect of Grazing-Mediated Dimethyl Sulfide (DMS) Production on the Swimming Behavior of the Copepod Calanus helgolandicus [PDF]
, 2013 Chemical interactions play a fundamental role in the ecology of marine foodwebs. Dimethyl sulfide (DMS) is a ubiquitous marine trace gas that acts as a bioactive compound by eliciting foraging behavior in a range of marine taxa including the copepod ...

EcosphereThe effects of grazing on natural grasslands' plant composition, diversity, and productivity depend on the intensity of grazing. Besides grazing intensity, animal composition is also important. However, whether and how sheep grazing intensity affects the

Plant community functional shifts in response to livestock grazing in intermountain depressional wetlands in British Columbia, Canada [PDF]
, 2010 Wetlands are ecologically and economically important ecosystems with high conservation value. Although wetland vegetation is strongly determined by abiotic factors, grazing disturbance may also be an important influence on this community.

Evaluating vegetated buffer zones for phosphorus retention in cereal and grass production [PDF]
, 2008 The buffer zones seem to be effective to stop erosion and trap particle bound P in surface runoff from the autumn ploughed clay soil. On pastures, the buffers are not so important, if P fertiliser is not surface applied and the grazing intensity is not ...

Higher sustainability performance of intensive grazing versus zero-grazing dairy systems [PDF]
Agronomy for Sustainable Development, 2012 Although grazing of dairy cows is an integral part of dairy farming in many European countries, farmers today more often choose for zero-grazing systems, where cows are housed throughout the year. Some studies already compared grazing and zero-grazing systems for specific issues such as labor efficiency, environmental impact, or animal welfare.

PLoS ONE, 2020 Grassland biodiversity is vulnerable to land use change. How to best manage semi-natural grasslands for maintaining biodiversity is still unclear in many cases because land-use processes may depend on environmental conditions and the indirect effects of ...
