Research on the spatial characterization of herder grazing intensity supported by mobile phone signaling data

Frontiers in Ecology and Evolution
IntroductionMobile phone signaling data have become one of the main types of data used to carry out spatial mobility analysis, but no research has simulated herders’ grazing intensity by using this measure.MethodsIn this paper, based on herders’ mobile ...

Factors affecting estuarine populations of Nereocystis luetkeana in Kachemak Bay, Alaska [PDF]

, 2003
Thesis (M.S.) University of Alaska Fairbanks, 2003Nereocystis luetkeana forms extensive kelp beds in Kachemak Bay, Alaska. Salinity and turbidity gradients apparently regulate kelp bed distribution throughout this estuary.

Study of the isotropic contribution to the analysis of photoelectron diffraction experiments at the ALOISA beamline

, 2002
The angular distribution of the intensity in photoemission experiments is affected by electron diffraction patterns and by a smoothly varying ISO contribution originated by both intrumental details and physical properties of the samples.

Emerging beam resonances in atom diffraction from a reflection grating [PDF]

, 2010
We report on the observation of emerging beam resonances, well known as Rayleigh-Wood anomalies and threshold resonances in photon and electron diffraction, respectively, in an atom-optical diffraction experiment.

Grazing regime rather than grazing intensity affect the foraging behavior of cattle

Ecological Informatics
Foraging behavior of cattle is a critical factor for sustainable grassland grazing. Investigating cattle's behavior under varying grazing strategies can offer valuable insights into the interactions between grazing animals and grasslands. In this study, we used a fenced grazing experiment to test the hypothesis that grazing pressure influences the ...

Grazing intensity drives above–belowground productivity trade-offs and reveals belowground dominance in temperate herbaceous marsh wetlands

Frontiers in Plant Science
IntroductionLivestock grazing, as a major anthropogenic disturbance, significantly affects plant species diversity and net primary productivity (NPP) in wetland ecosystems and their relationships with soil properties.

Calcium and Magnesium Released from Residues in an Integrated Crop-Livestock System under Different Grazing Intensities

Revista Brasileira de Ciência do Solo
Under integrated crop-livestock production systems (ICLS), plant and animal residues are important nutrient stocks for plant growth. Grazing management, by affecting the numbers of both plants and animals and the quality of residues, will influence ...

The influence of grazing on surface climatological variables of tallgrass prairie [PDF]

Mass and energy exchange between most grassland canopies and the atmosphere are mediated by grazing activities. Ambient temperatures can be increased or decreased by grazers.

Global meta-analysis reveals different grazing management strategies change greenhouse gas emissions and global warming potential in grasslands

Geography and Sustainability
Grazing management significantly influences greenhouse gas (GHG) emissions and the global warming potential (GWP) in grasslands. Yet, a limited understanding of the impact of grazing and grazing exclusion on GHG emissions and GWP in grasslands hinders ...

Image processing for grazing incidence fast atom diffraction [PDF]

, 2016
Grazing incidence fast atom diffraction (GIFAD, or FAD) has developed as a surface sensitive technique. GIFAD is less sensitive to thermal decoherence but more demanding in terms of surface coherence, the mean distance between defects.
