Optimizing rotational grazing in sheep management systems

Environment International, 1999
Abstract Rotational grazing on sheep farms was modeled using an iconic simulation modeling package. An event-driven modeling approach allowed the simulation of individual paddocks on a farm and their grazing. It permitted the effects of different levels of herbage allowance to be tested and measured with respect to pre- and post-grazing herbage mass,

Herbage volume per animal: A tool for rotational grazing management [PDF]

Journal of Range Management, 2000
The objective of this study was to provide a tool for maintaining a high grazing efficiency. In a rotational grazing system, the residual sward height does not provide enough information in advance to make the recommendation. The grazing management of 4 commercial dairy farms which differed greatly in their stocking rate, was monitored over 3 spring ...

Broadband Conductance Matching Effect in Conductive Metamirrors

Advanced Physics Research, EarlyView.
A conductance matching effect is revealed in conductive metamirrors whose input conductance can be broadband self‐matched to the free space when the conductivity‐thickness product equals 8 mS. This effect enables thickness‐invariant perfect absorption at low frequencies, and tunable resonances at higher‐order modes, providing new opportunities for ...

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Herbage accumulation and grazing losses on Mulato grass subjected to strategies of rotational stocking management

Scientia Agricola, 2013
Grazing management strategies affect not only herbage accumulation but also the efficiency of grazing. This study aimed to evaluate herbage accumulation (leaf, stem and dead material), grazing efficiency and losses of mulato grass (a Brachiaria ...

Rotational grazing

, 2018
Grazing is the action whereby livestock feeds freely on a pasture. There are several ways of managing livestock grazing and feeding, but the main distinction that can be made is between continuous and rotational grazing. Rotational grazing consists of dividing the pastures into smaller paddocks and establishing a rotation over the paddocks.

Repeating Nuclear Transients From Repeating Partial Tidal Disruption Events

Astronomische Nachrichten, EarlyView.
ABSTRACT Extragalactic nuclear transients that exhibit repeating outbursts can be modeled as the repeated dynamical interaction between bound stars and supermassive black holes (SMBHs). A subset of these transients, with recurrence timescales of months‐to‐years, have been explained as accretion flares from the repeated tidal stripping of a star by an ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Enabling pastoralist management of rangelands to achieve Land Degradation Neutrality

Frontiers in Ecology and the Environment, EarlyView.
Rangelands cover 54% of the global terrestrial area and are threatened by land conversion and degradation, which erodes their global value and weakens the livelihoods of pastoralists who manage them. Sustainable Development Goal Target 15.3 on Land Degradation Neutrality (LDN) provides a framework for sustainable rangelands management, but countries ...

The impact of different grazing intensity and management measures on soil organic carbon density in Zhangye grassland

Scientific Reports
Studying the spatial and temporal changes of grassland soil organic carbon (SOC) is helpful in promote the management of regional ecosystem carbon sinks. Grazing is one of the main ways of rational utilization of grassland.
