Suplementação energética na recria de fêmeas de corte em pastagem cultivada de inverno: produção animal Energy supplementation on rearing beef female in winter cultivated pasture: animal production

Revista Brasileira de Zootecnia, 2005
Foi avaliado o desempenho de novilhas de corte em pastagem de aveia preta (Avena strigosa Schreb) mais azevém (Lolium multiflorum Lam) submetidas aos seguintes tratamentos: 'Sem Suplemento'- animais exclusivamente em pastagem; 'Crescente' - animais ...

Montado Mediterranean Ecosystem (Soil–Pasture–Tree and Animals): A Review of Monitoring Technologies and Grazing Systems

Applied Sciences, 2023
Montado is an agro-silvo-pastoral ecosystem characteristic of the south of Portugal and called Dehesa in Spain. Its four fundamental components—soil, pasture, trees, and animals—as well as the climate make Montado a highly complex ecosystem.

Continuous feral horse grazing and grazing exclusion in mountain pampean grasslands in Argentina

Acta Oecologica, 2010
This paper evaluates changes in the composition and structure of plant communities and plant functional groups associated with the continuous presence of feral horses in mountain pampean grasslands in Argentina in order to explore the potential effects of horse removal on vegetation restoration.

Measuring production of continuously grazed hill pastures

Proceedings of the New Zealand Grassland Association, 1998
Estimates of pasture production are critical for comparing treatment effects in research trials, as inputs to decision support models, and for on-farm use in constructing grazing plans. We compared two techniques for measuring pasture production, over 2 years in 36 paddocks continuously grazed with sheep, on hill country at the Ballantrae Research ...

Protozoan Grazing, Bacterial Activity, and Mineralization in Two-Stage Continuous Cultures [PDF]

Applied and Environmental Microbiology, 1988
In two-stage continuous cultures, at bacterial concentrations, biovolumes, and growth rates similar to values found in Lake Vechten, ingestion rates of heterotrophic nanoflagellates (HNAN) increased from 2.3 bacteria HNAN −1 · h −1 at a growth rate of 0.15 day −1 to 9 ...

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 ...

Demonstrating Vibrational Current Generation With a Self‐Assembled Bioelectret

Advanced Functional Materials, EarlyView.
Vacuum‐deposited films of the plant‐derived molecule, Baicalein, form a self‐assembled bioelectret exhibiting spontaneous orientation polarization and a giant surface potential. The films induce alternating current during the vibration of a movable electrode without charging treatments. Hydrocarbon protection enhances the air stability of the Baicalein

Grazing weakens temporal stabilizing effects of diversity in the Eurasian steppe

Ecology and Evolution, 2018
Many biodiversity experiments have demonstrated that plant diversity can stabilize productivity in experimental grasslands. However, less is known about how diversity–stability relationships are mediated by grazing.

Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

Advanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable
