We determined the energy costs associated with the activities of beef cows grazing on Mediterranean foothill rangeland covered with herbaceous vegetation. Our central aim was to compare the energy… Expand
Energy cost of cows' grazing activity: Use of the heart rate method and the Global Positioning System for direct field estimation.
This study with grazing beef cows on the range was designed to explore the possibility of determining incremental energy expenditure (EE) in standing, traveling, and grazing relative to that in lying… Expand
A fecal near-infrared reflectance spectroscopy-aided methodology to determine goat dietary composition in a Mediterranean shrubland.
An ecologically sound approach to the problem of brush encroachment onto Israeli rangeland might be their utilization by goats, but better knowledge of the feeding selectivity and ability of goats to… Expand
Ecogeomorphic feedbacks in semiarid rangelands: a review.
Abstract The ecogeomorphic processes occurring on semiarid rangelands are reviewed, with emphasis on the source-sink relations and positive feedback loops that existed between shrub patches and… Expand

Rapid assessment of the nutritional quality of diets ingested by grazing animals is pivotal for successful cow-calf management in east Mediterranean rangelands, which receive unpredictable rainfall… Expand
Shrubs and herbaceous seed flow in a semi-arid landscape: dual functioning of shrubs as trap and barrier
Summary 1. Shrubs in arid and semi-arid ecosystems are often associated with three distinct patch types: the shrub core, the shrub periphery and surrounding open patches. The distribution of… Expand
Bite dimensions for cattle grazing herbage at low levels of depletion
The processes that occur during the depletion of a single feeding station by grazing cattle are important to our understanding of intake at larger spatial scales. Factorial experiments were conducted… Expand

BACKGROUND There is interest in using animal-mounted sensors to provide the detailed timeline of domesticated ruminant behaviour on rangelands. NEW METHOD Working with beef cattle, we evaluated the… Expand
Foraging behavior of two cattle breeds, a whole-year study: I. Heat production, activity, and energy costs.
The foraging behavior and energy costs of activity of 19 large-frame Beefmaster × Simford (BS) cross mature cows and 14 small-frame Baladi (BA) mature cows was determined. Cows were allocated to the… Expand
Foraging behavior of two cattle breeds, a whole-year study: II. Spatial distribution by breed and season.
Spatial distributions of 22 mature large-framed Beefmaster × Simford (BS) cross cows and 16 mature small-framed Baladi (BA) cows were determined. Cows were allocated to the same paddock of a… Expand
