Video recording and vegetation classification elucidate sheep foraging ecology in species‐rich grassland

Ecology and Evolution, 2021
Factors influencing grazing behavior in species‐rich grasslands have been little studied. Methodologies have mostly had a primary focus on grasslands with lower floristic diversity.

Harry Stobbs Memorial Lecture: Can grazing behavior support innovations in grassland management?

Tropical Grasslands-Forrajes Tropicales, 2013
Grazing is a fundamental process affecting grassland ecosystem dynamics and functioning. Its behavioral components comprise how animals search for feed, and gather and process plant tissues in different spatio-temporal scales of the grazing process ...

Winter Grazing on Cotton Stubble Affects Grazing Behavior and Feed Intake of Ewes [PDF]

, 2020
Abstract Background:In this study, we investigated the effects of cotton (Gossypium spp) stubble grazing during winter on the feed intake, grazing behavior, and blood chemical parameters of Altay ewes in Xinjiang, China. Eighty adult and twenty-five young ewes grazed continuously on cotton stubble from sunrise to sunset for 90 d during the ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Chemical State Detection and Charge Transfer in Complex Oxide Heterostructures via In Situ Auger Electron Spectroscopy

Advanced Functional Materials, EarlyView.
In situ Auger Electron Spectroscopy resolves oxidation states with high fidelity during the pulsed laser deposition of multivalent perovskite manganate and vanadate heterostructures. The chemical‐state signature is carried by the valence‐electron population of the transition‐metal cation, read out through the relative intensities of Auger fine ...

Beyond policy fatigue: how environmental literacy shapes sustainable grazing in China’s pastoral regions

Frontiers in Sustainable Food Systems
Grassland degradation poses severe ecological and socio-economic risks in China’s pastoral regions. The effectiveness of top-down policies is often constrained by high enforcement costs, low compliance, and a lack of intrinsic motivation among ...

The timing of pasture allocation and grass silage supplementation affect pasture intake, milk production and nitrogen partitioning of dairy cows

Spanish Journal of Agricultural Research, 2021
Aim of study: To evaluate the effect of time of pasture allocation (PA) and grass silage allocation on dry matter (DM) intake, grazing behaviour, milk production, rumen function and N partitioning of grazing dairy cows.

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Beef heifers grazing behavior and herbage intake in natural grassland under rotational grazing

Ciência Rural, 2015
It was evaluated the effect of two rest intervals between grazing occupations in rotational grazing; 375 and 750 DD (degree-days); based on the cumulative thermal sum necessary for leaf expansion of native grasses of two functional groups over the ...
