Environmental impacts of grazed pastures [PDF]
, 2010 Large nitrogen (N) surplus and return of excreta-N in localised patches at high N rates in intensively grazed pasture systems markedly increases the risk of N losses to waterways and the atmosphere. Here are described the main routes of N input to grazed

Habitat Associations of Sympatric Violet-Feeding Fritillaries (Euptoieta, Speyeria, Boloria) (Lepidoptera: Nymphalidae) in Tallgrass Prairie [PDF]
, 2017 At 106 tallgrass prairies in the midwestern USA, 18,055 individuals of six fritillary species (Lepidoptera: Nymphalidae) were counted in 552.9 hr and 987.1 kill of transect survey effort from 14 June to 13 September during 1988-96. The relative abundance

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Advanced Electronic Materials, EarlyView.Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Advanced Electronic Materials, EarlyView.Robust photoresponses and temperature adaptability were achieved in Ga2O3 solar‐blind UV photodetectors operated at temperatures between 100 and 450 K. The thermal‐driven evolution of oxygen vacancies in amorphous thin films brings about distinct non‐monotonic variations.

Halogeton Grazing Management: Historical Perspective
Journal of Range Management, 2002 Halogeton [Halogeton glomeratus (Bieb.) C. A. Mey], is a fleshy, annual, herbaceous species that was accidentally introduced into the western U.S. during the 20th century. Because it is highly poisonous to sheep (Ovis aries), this rather diminutive herb became the center of attention for biological research on Intermountain rangelands during the 1950s.

Toward Complete CO2 Electroconversion: Status, Challenges, and Perspectives
Advanced Energy Materials, EarlyView.Electrocatalytic CO2 reduction and CO2 batteries face challenges in achieving complete CO2 conversion with high conversion rates and Faradaic efficiency simultaneously. Existing systems compromise one for the other with incomplete CO2 conversion and inefficiencies, hindering practical applications. This perspective highlights state‐of‐the‐art progress,

Perspectives on conservation grazing: The need for monitoring and communication
Ecological Solutions and EvidenceConservation grazing is widely used to manage open ecosystems, but inconsistent definitions and inadequate reporting of grazing patterns hinder effective communication among researchers, practitioners and policymakers, limiting the understanding and ...
