Farm Animal Cognition—Linking Behavior, Welfare and Ethics

Farm animal welfare is a major concern for society and food production. To more accurately evaluate animal farming in general and to avoid exposing farm animals to poor welfare situations, it is necessary to understand not only their behavioural but also their cognitive needs and capacities. Thus, general knowledge of how farm animals perceive and […]

Zoo Research Guidelines: Studies of the effects of human visitors on zoo animal behaviour


Methodologies for the Care, Maintenance, and Breeding of Tropical Poison Frogs

The Biodiversity Laboratories at Saint Joseph’s University house more than 100 exotic and endangered animal species-including insects, fish, amphibians, and reptiles. Research in the laboratories is devoted, primarily, to understanding the genetic and ecological bases of animal behavior. In addition, a common theme of the work is the development of techniques for the successful care […]

Self-recognition in the Asian elephant and future directions for cognitive research with elephants in zoological settings

The field of animal cognition has grown steadily for nearly four decades, but the primary focus has centered on easily kept lab animals of varying cognitive capacity, including rodents, birds and primates. Elephants (animals not easily kept in a laboratory) are generally thought of as highly social, cooperative, intelligent animals, yet few studies—with the exception […]

The Effects of Visitor Density and Intensity on the Behavior of Two Captive Jaguars (Panthera onca)

Several researchers have reported significant effects of visitor density and intensity on captive animal behavior. This study determined whether this was the case for 2 captive jaguars housed at the Woodland Park Zoo, Seattle, WA. Subjects were monitored for changes in behavior as a function of visitor density and intensity. The jaguars were observed for […]

Spraying Effects on Goat Welfare in Hot and Humid Climate

Heat stress is one of the major factors adversely affecting animal welfare and thus economic benefits of farms. This study was designed to determine the effects of three different spraying methods on goats for reducing heat stress. Thirty goats divided into three groups for the trial (One time sprayed a day: OTS, Two times sprayed […]

Using The Observer for Animal Behavior Research: Stress and emotions in animals

Animals respond to inputs from their inner and outer environment with physiological and behavioral changes. They try to maintain a stable state by reacting to disturbances of the inner and outer world: their Umwelt. Under natural conditions an animal predicts and controls its Umwelt by feeding, moving, resting, socializing, communicating, etc. It has the freedom […]

Behaviour as a tool in the assessment of animal welfare

A central issue in animal welfare research is how to assess the welfare state of animals objectively and scientifically. I argue that this issue can be approached by asking two key questions: 1) is the animal physically healthy and 2) does the animal have what it wants? Behaviour is used to answer both of these […]

Odor landscapes and animal behavior: tracking odor plumes in different physical worlds

The acquisition of information from sensory systems is critical in mediating many ecological interactions. Chemosensory signals are predominantly used as sources of information about habitats and other organisms in aquatic environments. The movement and distribution of chemical signals within an environment is heavily dependent upon the physics that dominate at different size scales. In this […]
