Quantitative evaluation of grazing effect on nomadically grazed grassland ecosystems by using time-lapse cameras

Agriculture, Ecosystems & Environment, 2020
Abstract Grazing is a key factor in grassland disturbance that affects plant biomass, soil properties, and carbon exchange in grasslands. The objective of this study was to quantitatively evaluate the effects of grazing on grassland ecosystems in Mongolia.

The timing of birth in grazing Merino sheep

Australian Journal of Experimental Agriculture, 1993
During a 5-year study of lambing behaviour involving almost 1900 births by grazing ewes, the incidence of lambing peaked during the 5-h period 0900-1400 hours, when 28% of ewes lambed. Significant numbers of births occurred throughout the day, and so effective supervision of lambing would not be possible if attendance was restricted to daylight hours ...

Effects of grazed stubble height and timing of grazing on resprouting of clipped oak seedlings

Agroforestry Systems, 2018
Although a number of studies have investigated the effects of grazing frequency and intensity on seedling resprouting, the influence of grazed stubble height and timing of grazing on oak seedlings is little known. In the present study, we aimed to explore the effects of grazed stubble height and timing of grazing on the seedling resprouting of twelve ...

Time of flight grazing incidence small angle neutron scattering

The European Physical Journal Special Topics, 2009
Grazing incidence small angle neutron scattering (GISANS) overcomes the limitations of conventional small angle scattering with respect to extremely small sample volumes in the thin film geometry. In time of flight (TOF) mode neutrons with a broad range of wavelengths are used simultaneously and recorded as a function of their respective times of ...
