, 1978 Perennial ryegrass/white clover swards were manipulated to give a range of clover contents and structures. The influence of sward composition and structure on diet selection was examined using oesoph-ageally fistulated sheep grazing four plots with ...

Environmental Toxicology, EarlyView.ABSTRACT Microplastic (MP) pollution is widely recognized as an emerging environmental threat. Yet, most studies still rely on controlled experimental conditions that poorly reflect environmental complexity, potentially underestimating risks under realistic scenarios, particularly during short‐term exposures. Here, we tested whether acute oral exposure

Effect of breed and sward height on sheep performance and production per hectare during the spring and autumn in Northern Spain [PDF]
, 2002 Effects of breed and sward surface height on ewe liveweight and body condition changes and on lamb liveweight gains during grazing in the spring and autumn were studied. The output per hectare in each season was also calculated. A total of 112 Gallega

Environmental Toxicology, EarlyView.ABSTRACT Brazilian social stingless bees are important pollinators and producers of honey, wax, royal jelly, propolis, and other products. These species are experiencing a population decline, attributed to different factors, such as the excessive use of pesticides.

Wildlife Biology, EarlyView.As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

Factors influencing wintering turfgrass field use in Atlantic brant
Wildlife Biology, EarlyView.Atlantic brant Branta bernicla hrota increasingly use turfgrass fields, such as baseball fields and golf courses, throughout their wintering range. Most studies have focused on their primary food source, submerged aquatic vegetation, while studies of other goose species worldwide have examined field use in different contexts, including agricultural ...

International Journal of Urban and Regional Research, EarlyView.Abstract Much of the current popular and academic literature on the provision of green spaces is dominated by the assumption that ‘nature’ is an unalloyed positive, and that socioeconomic and racial exclusion from access to green spaces is a problem of unequal spatial distribution rather than of the form and content of particular urban designs.

Sward Height in Grazing Management: Vertical Profiles in Forage Quality [PDF]
Vertical and temporal trends in herbage yield and quality were assessed in a study sown in 1989 near Elora, Ontario. In a replicated field trial with 0.1 ha paddocks, Hereford heifers rotationally grazed 2 swards to each of 2 residual grazing heights ...

Methods in Ecology and Evolution, EarlyView.Abstract Observations of three‐dimensional (3D) coarse root system architecture remain limited because most measurement approaches require excavation. Here, we combined dense single‐ and multi‐channel 500 MHz ground‐penetrating radar (GPR) surveys with a flow‐guided connectivity framework to non‐destructively characterise the coarse root architecture ...
