Modelling the influence of rainfall variability and different grazing systems on the spatiotemporal dynamics and productivity of semiarid rangeland [PDF]

, 2010
Includes abstract.Includes bibliographical references (leaves 153-169).This study pursued a two-fold objective: firstly, to broaden our knowledge about the rainfall-plant-animal system dynamics; and secondly, to re-examine the rotational grazing system ...

Effects of initial disturbances and grazing regime on native grassland invasion by Eragrostis plana in southern Brazil

Perspectives in Ecology and Conservation, 2018
Extensive invasion of the Campos grasslands of southern Brazil by the South African grass, Eragrostis plana, is a serious conservation problem due to its low palatability and ability to quickly spread.

The impact of rotational grazing on biomass characteristics in boreal alluvial meadows [PDF]

Journal of Central European Agriculture
Northern Boreal alluvial meadows are semi-natural habitats that require extensive management. They also have lower productivity as compared to cultivated grasslands. The subsidies for keeping meadow habitats open are currently activity-based, not results-

Intake characteristics of perennial ryegrass varieties when grazed by yearling beef cattle under rotational grazing management [PDF]

, 2005
Four intermediate-heading perennial ryegrass (Lolium perenne L.) varieties, which in previous studies had been associated with high- or low-intake characteristics when swards containing them had been continuously stocked with sheep, were sown as ...

Will current rotational grazing management recommendations suit future intensive pastoral systems

, 2021
This review aimed to determine whether current grazing management practices will suit future intensive rotationally grazed pastoral systems. A review of literature on grazing management recommendations found that there was good agreement on the ...

Embracing inherent and imposed sources of heterogeneity in rangeland bird management

Ecosphere, 2022
Rangeland simplification is a global threat to biodiversity. Historically, rangelands exhibited varied vegetation structure, which provided a diverse wildlife habitat.

Exchange‐Coupled Two‐Dimensional MOFs

Advanced Functional Materials, EarlyView.
Graphene mediates ferromagnetic coupling between two‐dimensional metal‐organic frameworks and cobalt. Fe‐tetracyanobenzene develops a remanent magnetic response whose orientation follows the cobalt magnetization direction and persists up to room temperature, whereas Ni‐TCNB remains only field‐polarized.

Spatial Control of Light‐Responsive Proteins and Optogenetics Within Hydrogels via Volumetric Bioprinting

Advanced Materials, EarlyView.
Spatiotemporal control over cell behavior within bioprinted constructs remains a key challenge in biofabrication. Volumetric bioprinting using multi‐wavelength light sources permits to activate light‐sensitive intracellular proteins as well as optogenetic gene and protein expression circuits in bioprinted cells, in addition to enabling fast printing of

Atomic‐Scale Detection of Néel Vector Switching in the Single‐Layer A‐Type Antiferromagnet Cr2S3‐2D

Advanced Materials, EarlyView.
Interfacial electron donation from graphene redistributes charge within single‐layer Cr2S3‐2D, preferentially accumulating at the lower Cr/S plane. The resulting minute magnetic imbalance lifts the equivalence of the two magnetic sublayers, enabling atomic‐resolution identification and field‐induced control of Néel‐vector states in a two‐dimensional A ...

Operational strategies for optimizing grazing when using automatic milking systems in organic dairy production [PDF]

, 2013
Successful grazing when using AMS is possible without having to devote a great deal of time to organize and fetch cows every day. However, a careful strategy and good infrastructure, and observation of cow behaviour and pasture are necessary, and the ...
