Successional trajectories of herbaceous functional groups induced by grazing exclusion in the desert of the western Inner Mongolia plateau

open access: yesFrontiers in Ecology and Evolution
Grazing-induced grassland degradation has attracted increasing attention worldwide, with arid desert regions being particularly affected due to their low precipitation and fragile ecosystems.

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

open access: yesAdvanced 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 ...

High Grazing Rates on Cryptophyte Algae in Chesapeake Bay

open access: yesFrontiers in Marine Science, 2018
Cryptophyte algae are globally distributed photosynthetic flagellates found in freshwater, estuarine, and neritic ecosystems. While cryptophytes can be highly abundant and are consumed by a wide variety of protistan predators, few studies have sought to ...

Apparent selectivity of sheep in deferred marandu palisadegrass pastures with variable initial heights [PDF]

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2019
The objective of this study was to evaluate the apparent selectivity of sheep in marandu palisadegrass (Urochloa brizantha cv. Marandu) pastures with four heights at the beginning of the deferment period (15, 25, 35 and 45cm). The deferment period was 92

Grazing Selectivity and In Vivo Digestibility of Switchgrass Strains Selected for Differing Digestibility

open access: yesJournal of Animal Science, 1989
Animal selectivity and digestibility differences among switchgrass strains selected for different in vitro dry matter digestibilities (IVDMD) were measured in a grazing trial with esophageally fistulated steers and a sheep digestion trial. Extrusa selected by esophageally fistulated steers grazing high-IVDMD (Trailblazer), Pathfinder and low-IVDMD ...

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

open access: yesAdvanced 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

Defoliation Dynamics on Grazing Horizons in Pastures Intercropped by Panicum maximum, Brachiaria brizantha, and Brachiaria decumbens

open access: yesTropical Animal Science Journal, 2020
The aim of this study was to quantify and verify the defoliation dynamics process of the Panicum maximum, Brachiaria brizantha, and Brachiaria decumbens intercropping during the formation of four grazing horizons in lenient grazing intensities and high ...

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

open access: yesAdvanced 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

Preference of fodder marandu-grass (Urochloa brizantha cv. Marandu) managed under intermittent stocking and submitted to nitrogen levels in the legal Amazon

open access: yesSemina: Ciências Agrárias, 2015
The objective of this study was to evaluate the preference of forage intake on pastures subjected to doses of N. The experimental design was a randomized blocks, with split plots in 5 x 3, five N rates (0, 25, 50, 75 and 100 kg ha-1 cycle-1) and three ...
