Effect of Enclosure Size and Complexity on the Behaviors of Captive Chimpanzees (Pan troglodytes)

Reports describing the implementation of innovative facility designs are important to both the primate caregiving community and policymakers reviewing current U.S. Department of Agriculture regulations. This study documents the changes in behavior of 5 adult chimpanzees that coincided with transfer from the Psychology Building Facility to the large and complex chimpanzee enclosure within the Chimpanzee […]

The Behavioral Ecology of Intermittent Locomotion

Most physiological and ecological approaches to animal locomotion are based on steady state assumptions, yet movements of many animals are interspersed with pauses lasting from milliseconds to minutes. Thus, pauses, along with changes in the duration and speed of moves, form part of a dynamic system of intermittent locomotion by which animals adjust their locomotor […]

Ontogeny of locomotory behaviour in the American locust, Schistocerca americana: from marathoner to broad jumper

Developmental changes in locomotory ability may affect many aspects of organismal behaviour and ecological success. While juvenile vertebrates have lower power output and endurance than older animals, the effects of ontogeny on locomotory performance in invertebrates are unknown. Among insects, grasshoppers serve as an ideal model to study ontogeny of locomotory behaviour. Ecological and behavioural […]

The effects of temporary cover on the behavior of socially housed stumptailed macaques (Macaca arctoides)

Abstract 10.1002/zoo.1430100605.abs To examine the effects of the provision of temporary cover on the behavior of stumptailed macaques (Macaca arctoides), a single group of 26 animals was observed during 25 testing periods over 7.5 months. During each testing period, the group was observed under two conditions. In the Cover condition, two solid temporary walls 9.6 […]

Behavioral patterns and communication in feral asses (Equus africanus)

The behavior of feral populations of the African wild ass (Equus africanus) were studied in the Northern Panamint Range of Death Valley National Monument for 20 months from 1970 to 1973 [Moehlman, P.D., 1974. Behavior and ecology of feral asses (Equus asinus). PhD dissertation, University of Wisconsin, Madison, 251 pp.; Moehlman, P.D., 1979. Behavior and […]

Investigation of distances covered by fattening pigs measured with VideoMotionTracker®

The investigation was carried out with altogether 144 pigs kept in groups of 6 or 12. Every pen was equipped with perforated floor. Water and the in-house compound feed with different elements depending on the fattening period were available ad libitum during the whole fattening period. At the beginning of each fattening period all pigs […]

Circadian behavioral and melatonin rhythms in the European starling under light-dark cycles with steadily changing periods: Evidence for close mutual coupling?

In European starlings exposed to constant conditions, circadian rhythms in locomotion and feeding can occasionally exhibit complete dissociation from each other. Whether such occasional dissociation between two behavioral rhythms reflects on the strength of the mutual coupling of their internal oscillators has not been investigated. To examine this, as well as to elucidate the role […]

Why are sheep lame? Temporal associations between severity of foot lesions and severity of lameness in 60 sheep

We investigated the temporal associations between the severity of foot lesions caused by footrot (FR) and the severity of lameness in sheep. Sixty sheep from one farm were monitored for five weeks. The locomotion of each sheep was scored once each week using a validated numerical rating scale of 0-6. All feet were then examined, […]

The locomotion of dairy cows in passageways with different light intensities

Guidelines for the housing of dairy cows do not address the provision of supplementary lighting in passageways, other than for inspection of the animals. Two experiments were conducted to investigate whether lighting passageways to various intensities influenced the locomotion of dairy cows. The first experiment compared the locomotion of dairy cows in a dark or […]

Thermoregulatory behavior in infant Norway rats ( Rattus norvegicus) and Syrian golden hamsters ( Mesocricetus auratus): Arousal, orientation, and locomotion

The responses of 2- and 8-day-old rats (Rattus norvegicus) and hamsters (Mesocricetus auratus) to thermal stimulation were assessed in 4 experiments. In Experiment 1, the surface underlying the pup was cooled, and the latency to escape to a region of warmth was measured. Experiment 2 required pups to locomote farther to gain access to warmth. […]
