Comparison of Semi-Captive and Wild Gray-Shanked Douc Langurs’ (Pygathrix Cinerea) Activity Budgets
… wild. In my study, I assessed the group members' activity budgets and feeding behaviors and compared my data to that obtained in a study of wild GSD langurs. I collected data using instantaneous scan sampling at 2 minute intervals (Altmann, 1974). This comparison may assist future conservationists …

Using activity budgets and space use preferences to define enclosure appropriateness for African painted dogs, Lycaon pictus (Temminck 1820)
… of how an animal uses its space and activity budgets may be required to understand their biological requirements more fully in zoological environments. The findings in these behaviour observations will aid the design of exhibits and, in turn, potentially maximize the animals’ welfare. …

The Activity Budgets of Captive Javan Gibbons (<i>Hylobates moloch</i>) and their Response to Visitor Presence or Absence
… to assess the impact of visitor presence on the activity budgets of captive Javan gibbons. Using continuous sampling, I recorded the activity budgets of 10 Javan gibbons housed at the Gibbon Conservation Center (GCC) in Santa Clarita, California. I collected data in the mornings, middays, and …

Factors Influencing Travel Order as Proxy for Leadership and Trade-offs in Activity Budgets in Lactating and Nonlactating African Savanna Elephants
… or reproductive investment and shape individual activity budgets and behavioral patterns. To maximize nutritional and energetic intake females may increase time allocated to foraging or access resources through risk-prone behaviors, represented as aggression or leadership. Conversely, to minimize …

Factors That Affect Harem Stability in a Feral Horse (Equus caballus) Population on Shackleford Banks island, NC
… during the breeding season and examined mare activity budgets and harassment rates to determine if these factors influence harem stability. I hypothesized that 1) immunocontraception would increase the rates at which mares changed harems during the breeding season 2) activity budgets of …

Behavioral and Reproductive Aspects of Captive Maxwell's Duiker (<em>Cephalophus mawellii</em>) Husbandry
… were to quantify the effects of housing on activity budgets and progesterone cycling. Four animals were studied across two housing situations: housed individually versus housed in a grouped setting. Behavioral observations revealed no significant change in access to resources, rumination, or …

Effect of Group Size on the Activity Budget of Two Captive Chimpanzees (<i>Pan troglodytes</i>)
… welfare. By tracking each chimpanzee’s activity budgets, managers can assess welfare and make improvements or adjustments if necessary. I looked at the activity budgets of two captive chimpanzees after the death of a group member and the two chimpanzees’ subsequent relocation to a novel, …

Efficacy of an Electronic Scarecrow on 4 Mammalian Crop-Raiders in Limpopo Province, South Africa
… control group animals to examine differences in activity budgets and behaviors of interest between groups. Compared to animals at sites with an inactive or no scarecrow, I hypothesized that animals in the treatment group would have altered activity budgets and rates of behaviors; that they would …

Fine-scale drivers of African Penguin prey dynamics in Algoa Bay, South Africa, and their impacts on penguin foraging ecology
… simultaneously during a subset of fish surveys. Activity budgets of penguins calculated from these simultaneous deployments were modelled against the abundance of their prey to elucidate hypothesised functional relationships. Finally, the direct influence of purse-seine fishing on both targeted …

Behavioural and isotope ecology of marine-foraging chacma baboons (Papio ursinus) on the Cape Peninsula, South Africa
… of marine foraging on ranging behaviour and activity budgets through different seasons have yet to be quantified. Furthermore, all previous studies included data from troops that had access to nutrient-rich exotic foods, which may have reduced their reliance on marine organisms. For this …

Selection and Use of Aquatic Vegetation by Migratory Waterfowl in North Central Texas
… almost empty ponds received minimal use. Time activity budgets were conducted on waterfowl utilizing mixed native and hydrilla ponds to compare waterfowl time partitioning on native aquatic vegetation versus hydrilla. Although only minor differences were found in time budgets, social status …

Positional behavior and habitat use of Peters’ Angola black and white colobus monkey (Colobus angolensis palliatus) in structurally distinct areas of the Diani Forest, Kenya
… at 3 minute time intervals.Overall activity budgets and strata use differed significantly between all troops while support use of one troop was significantly different from that of the others. Overall locomotor and postural behaviors were largely consistent among all habitats. …

Examining Environmental Use by Captive <i>Lemur catta</i> and <i>Varecia rubra</i>
… functions at the Woodland Park Zoo, Seattle, WA. Activity budget and spatial use data I collected revealed that lemurs at the Woodland Park Zoo did not seem to spend an atypical proportion of their behaviors as inactive compared to their wild counterparts. However, neither species utilized the …

Flightless Giant Canada Goose Depredation Abatement and Disgestibility of Selected Crops in South Dakota
… evaluate alfalfa visual barrier effectiveness. Activity budgets and feeding rates for goose family groups were also recorded opportunistically. In 1998, a larger barley food plot was established on the same site and the alfalfa visual barrier eliminated to determine if this would deter geese …

The Relationship of Dominance, Reproductive State and Stress in a Non-Cooperative Breeder, The Domestic Horse (<em>Equus caballus</em>)
… state can affect behavior, I examined activity budgets, behavioral patterns, and social interactions, as well as the proximity and identity of neighbors in the social group. At two facilities in Kentucky, I recorded the social interactions and measured fecal glucocorticoids in pastured, …

The Ecology and Behaviour of the Common hippopotamus, Hippopotamus amphibious L. in Katavi National Park, Tanzania: Responses to Varying Water Resources
… Hippopotami showed spatial differences in their activity budgets and the frequency of behavioural events at these sites, which were consistent with the way they responded to variation in water availability between seasons. Extrapolating these findings to predict responses to future changes in …

AMUR TIGER PREDATION AND ENERGETIC REQUIREMENTS IN THE RUSSIAN FAR EAST: NEW INSIGHTS FROM GLOBAL POSITIONING SYSTEM COLLARS
… We then used empirical movement rates and activity budgets derived from GPS data to estimate the daily energetic requirements for tigers to maintain a subsistence diet. Overall movement rates averaged 888.3 meters/hour, and 6.6 km/day. Our energetics model suggests an average male tiger …

Aspects of the spatial and behavioural ecology of Hippopotamus amphibious in the Saint Lucia Estuary, KwaZulu-Natal, South Africa
… methods in an attempt to determine the diurnal activity budgets and social interactions of a single group near the mouth of the St Lucia Estuary. I used non-parametric tests to evaluate differences in behaviour with daytime and across sampling days with a view to an improved understanding of how …
