An Economic and Environmental Analysis of Virtual Fencing for Precision Grazing

Journal of Agricultural Economics, EarlyView.
ABSTRACT The UK grazing livestock sector is challenged by declining farm profitability and stringent environmental policy. Innovative technologies such as virtual fencing could enable a balanced economic and environmental performance of beef production. Virtual fencing is a livestock management tool relying on invisible boundaries perceived as auditory,

Relationship Between Height and Sward Quality in Rotational Dairy Systems

Height is a good guide for management in dairy systems.Intake by dairy cows depends on amount offered and quality of pasture and for this reason a relationship between that offered and pasture quality with height should be studied.

Methods of Ryegrass Establishment (\u3cem\u3eLolium multiflorum\u3c/em\u3e Lam.) Affecting Optimal Sward Height to Maximize the Intake Rate

, 2019
In integrated systems it is common to use the no-tillage method. The adoption of this method improves the system\u27s sustainability (Laurent et al. 2011).

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Sward Height on the Performance of Cow-Calf Units and Yearling Steers Grazing Cool Season Pasture

Performance and grazing time of cow-calf units and yearling steers were determined over four years on naturalized cool season pastures maintained at a sward height of 4-6, 6-8, 8-10, or 10-12 cm.

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

Archaeometry, EarlyView.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

Ortolan buntings (Emberiza hortulana) consistently select breeding territories with structurally diverse crops on well‐drained soils

Conservation Science and Practice, EarlyView.
This study investigated consistency in habitat selection over a 12‐year period in a breeding population of Ortolan Bunting in Uelzen, Lower Saxony (Germany). We demonstrate strong interannual variation in crop type preferences and avoidance and breeding territories were strongly associated with well‐drained soils with low soil fertility.

Colonization and extinction lags drive non‐linear responses to warming in mountain plant communities across the Northern Hemisphere

Ecography, EarlyView.
Global warming is changing plant communities due to the arrival of new species from warmer regions and declining abundance of cold‐adapted species. However, experimentally testing predictions about trajectories and rates of community change is challenging because we normally lack an expectation for future community composition, and most warming ...
