Resumen

This study tested targeted grazing weeds with cattle and white-tailed deer (Odocoileus virginianus). Using forage manipulation techniques, we attempted to encourage cattle and white-tailed deer to graze weeds. Cattle were encouraged to target graze leafy spurge (Euphorbia esula L.). We established that cattle will attempt to consume leafy spurge from feed bunks but not from pasture. Two projects were developed to test targeted grazing of Canada thistle (Cirsium arvense) by white-tailed deer. The first project was a behavior study using a rationed pelleted feed with Canada thistle. The second a

Resumen

The aim of this experiment was to test whether LIPX-induced decreases in body fat affect appetitive (foraging effort and food hoarding) or consummatory (food intake) ingestive behaviors and whether the effects of LIPX on these behaviors is in turn affected by changes in energy expenditure produced by varying the amount of work required to obtain food. This was accomplished by housing male Siberian hamsters (Phodopus sungorus) in a foraging/hoarding apparatus where food pellets (75 mg) could be earned by completing various wheel running requirements.

Resumen

A widespread problem in the housing of captive animals is the occurrence and development of abnormal behaviors. In the pig breeding industry the abnormal behaviors causing the biggest welfare problems are stereotypies such as tail-biting, ear-biting, equipment-biting and belly-nosing. In this study a rope and an activation ball were tested as curative treatments to reduce the performance of these stereotypies by inducing the underlying innate behaviors. A total of 141 pigs spread over 18 pens were used as test-subjects. They were divided into three groups which were introduced to one of the tw

Resumen

Bat populations in the eastern United States are currently declining at unprecedented rates as a result of habitat loss, commercial wind energy development, and white-nose syndrome. Effective conservation of these declining populations requires knowledge of several aspects of summer and winter ecology, including daytime habitat use (day-roost selection and social behaviors), nocturnal habitat use (foraging habitat selection, prey selection, and prey abundance), and winter hibernation (torpor) patterns.

Resumen

Wild, native bees (Hymenoptera: Apoidea) provide pollination services valued at nearly $3 billion to U.S. agriculture annually, and are the primary pollinators maintaining plant communities in natural landscapes, an ecosystem service of incalculable worth.

Resumen

Stereotypic behaviors in all animals are more often than not associated with poor welfare. Limited access to perform species specific behaviors is often a reason for the development of stereotypies. Elephants with their great intelligence and need of social contact, coupled with a destructive a behavior are especially difficult to house in captivity. To decrease the occurrence of stereotypic behaviors in elephants, environmental enrichment in form of food enrichment is a good option, since elephants have a great need of foraging.

Resumen

The ability to invent new solutions to old or novel problems is often equated with intelligence, both in humans and non-human animals. Behavioural flexibility can be defined operationally by looking at the frequency of novel or unusual behaviours, i.e. innovations, in different taxa. Despite the potential survival benefits of behavioural flexibility in the face of changing conditions, there is variation among taxa in the propensity to innovate. Here, I examine in detail one foraging innovation, dunking behaviour (the immersion of food items in water) in Carib grackles (Quiscalus lugubris) of B

Central place foragers, such as territorial hummingbirds, feed from resources that tend to be constant in space and to replenish with time (e.g. nectar in flowers). The ability to remember both where and when resources are available would allow these animals to forage efficiently. Animals that feed at multiple locations would also benefit from forming routes between these multiple locations. Hummingbirds are thought to forage by repeating the order in which they visit several locations following a route called a “trapline”, although there are no quantitative data describing this behaviour.

Resumen

Movements of animals form a vital link between individual behaviour and spatial processes affecting populations, communities and ecosystems. Predators often have to search for prey that is unpredictable or patchily distributed and increasingly have to do so in habitats that are changing as a result of climate change or anthropogenic activity. Our understanding of animal movement has been revolutionised by the development of miniaturised loggers which allow tracking of individual animals over a range of spatial and temporal scales. However, while flight heights of birds are a critical component

Resumen

Social foraging behaviour has an important influence on individuals’ survival and reproduction through its role in the acquisition of food resources. It also determines the amount of foraging time required in differing environments, and so the amount of time available for other activities, such as socialising and resting, which have been implicated in an individual’s fitness, as well as the stability of the wider social group. In this thesis I explore the links between these two processes by investigating the drivers of social foraging behaviour, and how the foraging time budgets that this beh

Bumble bees (bombus spp.) are significant pollinators of many plants, and are particularly attracted to mass-flowering crops such as Oilseed Rape (Brassica Napus), which they cross-pollinate. B. napus is both wind and insect-pollinated, and whilst it has been found that wind is its most significant pollen vector, the influence of bumble bee pollination could be non-trivial when bee densities are large. Therefore, the assessment of pollinator-mediated cross-pollination events could be important when considering containment strategies of genetically modified (GM) crops, such as GM varieties of B

Savannah baboons are amongst the most intensively studied taxa of primates, but our understanding of their foraging strategies and diet selection, and the relationship of these to social processes is still rudimentary. These issues were addressed in a 12-month field study of olive baboons (Papio anubis) on the Laikipia plateau in Kenya. Seasonal fluctuations in food availability were closely related to rainfall patterns, with the end of the dry season representing a significant energy bottleneck. The distribution of water and of sleeping sites were the predominant influences on home range use,

Few studies have rigorously assessed the adaptive value of diel rhythms in animals.

However, assays of antipredator response within webs revealed more complex diel patterns of avoidance behaviors and no pattern of avoidance behavior duration. Assays of prey c
