A cross-species comparison of abnormal behavior in three species of singly-housed old world monkeys
Contributor(s):: Lutz, Corrine K.
Abnormal behavior occurs in a number of captive nonhuman primate species and is often used as an indicator of welfare. However, reported levels of abnormal behavior often vary across species, making general welfare judgments difficult. The purpose of this study was to assess differences in levels...

When dogs look back: inhibition of independent problem-solving behaviour in domestic dogs ( Canis lupus familiaris) compared with wolves ( Canis lupus)
Contributor(s):: Udell, M. A. R.
Domestic dogs have been recognized for their social sensitivity and aptitude in human-guided tasks. For example, prior studies have demonstrated that dogs look to humans when confronted with an unsolvable task; an action often interpreted as soliciting necessary help. Conversely, wolves persist...
The Role of Hybridization and the United States Fish and Wildlife Service Biologists' Discretion in the Implementation of the Endangered Species Act
Contributor(s):: Jennifer F. Lind-riehl
The Endangered Species Act (ESA) requires that the “best available scientific and commercial data” be used to enable the protection of critically imperiled species from extinction and preserve biodiversity. However, the ESA does not provide specific guidance on how to apply this...
Abnormal behavior in caged birds kept as pets
Contributor(s):: Hoek, C. S. van, Cate, C. ten
There are a limited number of studies dealing with abnormal behavior in caged birds kept as pets. However, these studies demonstrate the presence of abnormal behavior in both songbirds and parrots. Ethological studies on these birds, as well as studies on domestic and zoo birds, indicate that...

Species-Specific Differences and Similarities in the Behavior of Hand-Raised Dog and Wolf Pups in Social Situations with Humans
Contributor(s):: Gácsi, Márta, Gy?ri, Borbála, Miklósi, Ádám, Virányi, Zsófia, Kubinyi, Enik?, Topál, József, Csányi, Vilmos
In order to reveal early species-specific differences, we observed the behavior of dog puppies (n = 11) and wolf pups (n = 13) hand raised and intensively socialized in an identical way. The pups were studied in two object-preference tests at age 3, 4, and 5 weeks. After a short isolation, we...

Do the stereotypies of pigs, chickens and mink reflect adaptive species differences in the control of foraging?
Contributor(s):: Mason, G., Mendl, M.
Species differences in food-related stereotypies and natural foraging behaviour are discussed, and evolutionary explanations for these species differences, and reasons why apparent species differences in stereotypy may be artefacts of husbandry are postulated.
Comparative behaviour of free-ranging blackbirds ( Turdus merula ) and silvereyes ( Zosterops lateralis ) with hexose sugars in artificial grapes
Contributor(s):: Saxton, V. P., Hickling, G. J., Trought, M. C. T., Creasy, G. L.
In order to detect bird responses to sugar parameters of ripening grapes, artificial grapes containing controlled concentrations of hexose sugars were offered to free-range blackbirds (Turdus merula) and silvereyes (Zosterops lateralis). Time-lapse video was used to observe the two species of...
