Foragers that feed on hidden prey are uncertain about the intake rate they can achieve as they enter a patch. However, foraging success can inform them, especially if they have prior knowledge about the patch quality distribution in their environment. We experimentally tested whether and how red knots (Calidris canutus) use such ...

Humans, chimpanzees, capuchins and aye-ayes all display an unusually high degree of encephalization and diverse omnivorous extractive foraging. It has been suggested that the high degree of encephalization in aye-ayes may be the result of their diverse, omnivorous extractive foraging behaviors. In combination with ...

There are at least five scales com- monly used worldwide to describe stages of growth of wheat and other small grains of wheat and how management inputs at specific growth stages can affect for- age and grain yield. Probably significant event in achieving high yield of grain and/or forage in wheat is stand establishment. Planting
Lambs were grazed on monospecific swards of one of six forages, some containing condensed tannins (CT); sulla (Hedysarum coronarium), Lotus corniculatus and L. pedunculatus and some without CT (lucerne (Medicago sativa), plantain (Plantago lanceolata) and a ryegrass/white clover pasture (Lolium perenne/Trifolium repens)) to evaluate effects of forage type ...

All forager (or hunter-gatherer) societies construct niches, many of them actively by the concentration of wild plants into useful stands, small-scale cultivation, burning of natural vegetation to encourage useful species, and various forms of hunting, collectively termed 'low-level food production'. Many such niches are stable and can continue indefinitely, because ...

Performance and production of growing cattle (Bos taurus) on Coastal Bermudagrass [Cynodon dactylon (L.) Pers.] pasture are affected by forage allowance, but possible interactions with fertilizer nutrient source (i.e., inorganic vs. organic) and time have not been well described. We evaluated the effects of 3 nutrient sources with equivalent N rates: 1) inorganic, 2) crimson ...
Arkansas beef producers rely on both warm season (bermudagrass) as well as cool season (usually endophyte-infected tall fescue) perennial forages to achieve as close to a 12-month grazing season as possible. Even with this combined warm-cool season forage system, ¿forage gaps¿ still exist at certai...

The ability to transform chloroplasts in multiple species is important for improving agricultural traits.

The effect of stocking rate on forage growth has attracted a great deal of research attention in forage science. Findings show that forage growth may be affected by stocking rate and there is the consensus that high stocking rates lead to soil compaction, which could also in turn affect forage ...
Managing forages as living mulches during row crop production requires suppressing the forages to produce economical crop yields. The objective of this research was to identify forage plants with varied growth habit, persistence, and yield potential to provide desirable ecosystem functions and high ...
This work gives a proof of convergence for a randomized learning algorithm that describes how anoles (lizards found in the Carribean) learn a foraging threshold distance. This model assumes that an anole will pursue a prey if and only if it is within this threshold of the anole`s perch. This learning algorithm was proposed by the biologist Roughgarden and his colleagues. They ...

Bermudagrass is the most important warm-season grass forage for the South. Cultivars with good quality traits such as high dry matter digestibility have translated into higher daily gains for beef and improved milk production in dairy cattle.

We propose a method of automatically generating qualitative equations, i.e., monotonic and differential relations among the variables, to model and analyze macro-behaviors of foraging in ant colony. Foraging is a well-coordinated group behavior of ant colony, which is achieved by the cooperation of individual ants. We executed ...
Sonar techniques were used to quantitatively observe foraging predators and their prey simultaneously in three dimensions. Spinner dolphins foraged at night in highly coordinated groups of 16-28 individuals using strict four-dimensional patterns to increase prey density by up to 200 times. Herding exploited the prey's own avoidance ...

1. Identification of foraging behaviour and the ability to assess foraging success is critical to understanding individual and between-species variation in habitat use and foraging ecology. For pelagic predators, behaviour-dependent foraging metrics are commonly used to identify important ...
The success of most foragers is constrained by limits to their sensory perception, memory, and locomotion. However, a general and quantitative understanding of how these constraints affect foraging benefits, and the trade-offs they imply for foraging strategies, is difficult to achieve. This article develops ...
Numerous models of ungulate foraging behavior have been published, but data on foraging behavior for wild North American ungulates relevant to model testing are scarce.

Commercial lots of alfalfa (Medicago sativa L.) hay are often bought and sold on the basis of forage quality. Proper sampling is essential to obtain accurate forage quality results for pricing of alfalfa hay, but information about sampling is limited to small, 20- to 40-kg rectangular bales. Their objectives were to determine the within-bale variation in ...
We compared prefledging growth, energy expenditure, and time budgets in the arctic-breeding red knot (Calidris canutus) to those in temperate shorebirds, to investigate how arctic chicks achieve a high growth rate despite energetic difficulties associated with precocial development in a cold climate. Growth rate of knot chicks was very ...
North American porcupines (Erethizon dorsatum) subsist predominantly on low-protein, high-fiber, high-tannin diets. Therefore, we measured the porcupine's ability to digest dry matter, fiber, and protein by conducting digestion trials on eight natural forages and one pelleted ration varying in concentration of fiber, nitrogen, and ...
Planting and harvesting high yielding forage grasses may remove phosphorus (P), copper (Cu) and zinc (Zn) from surface soils with a long history of broiler litter application.
