“…Behavioral stereotypies have been associated with frustrated feeding motivation in confined animals fed nutritionally complete but diminutive meals and may contribute to the performance of regurgitation and reingestion (R/R) in captive gorillas [Lukas, 1999]. R/R refers to the voluntary, retrograde movement of food or fluid from the esophagus or stomach into the mouth [Lukas, 1999]. Common in captive gorillas, it has not been reported in wild populations.…”

“…Common in captive gorillas, it has not been reported in wild populations. Although it has not been associated with health problems, it is unsightly to observe and may indicate deficiencies in the captive gorilla diet [Lukas, 1999]. A high rate of R/R in the indoor holding area at Zoo Atlanta [Lukas et al, 1997], especially at the end of the day, led to an examination of dietary factors that might influence such behavior at that time.…”

“…Gorilla regurgitation has been compared with rumination disorder in humans [Gold and Bres, 1986;Lukas, 1999]. Because post-meal rumination of food in humans is facilitated by large quantities of liquid [Shay and Johnson, 1984], late afternoon peaks of R/R may have been enhanced by the relatively large quantity of milk that each gorilla quickly consumed during the indoor evening meal at Zoo Atlanta.…”

Urinary 2‐thiothiazolidine‐4‐carboxylic acid (TTCA) concentrations and corresponding personal breathing zone carbon disulfide (CS2) air concentrations were measured for worker populations at a Tennessee rubber product facility and a Virginia viscose rayon plant. At the rubber product facility, all of the 19 workers had urinary TTCA levels less than the limit of detection (LOD) of about 0.03 mg/L, equivalent to less than 0.5 ppm of CS2 in air. At the viscose rayon plant, five of six workers, although wearing half‐mask cartridge respirators, showed increased urinary TTCA during the workshift. The cutters and spinners had the largest increases in urinary TTCA concentrations; they also had the highest breathing zone exposures to CS2. The TTCA concentrations for three cutters and spinners did not return to normal preshift levels of <0.3 mg/g creatinine before the start of the next shift. The arithmetic mean respirator workplace protection factor (WPF) was 7.0 ± 2.2. Increase in urinary TTCA concentration during the workshift and postshift urinary TTCA concentration reflected CS2 air concentration equally well. In conjunction with air monitoring results, urinary TTCA concentrations allow determination of the WPF afforded workers wearing respirators and identify workers not adhering to safety rules and good work practices. Workers at risk of adverse health effects from overexposure to CS2 for any reason may thus be identified. Am. J. Ind. Med. 33:48–54, 1998. © 1998 Wiley‐Liss, Inc.

Zoos, aquariums, and other captive animal facilities offer promising opportunities to advance the science and practice of behavior analysis. Zoos and aquariums are necessarily concerned with the health and well-being of their charges and are held to a high standard by their supporters (visitors, members, and donors), organized critics, and the media. Zoos and aquariums offer unique venues for teaching and research and a locus for expanding the footprint of behavior analysis. In North America, Europe, and the UK, formal agreements between zoos, aquariums, and university graduate departments have been operating successfully for decades. To expand on this model, it will be necessary to help zoo and aquarium managers throughout the world to recognize the value of behavior analysis in the delivery of essential animal health and welfare services. Academic institutions, administrators, and invested faculty should consider the utility of training students to meet the growing needs of applied behavior analysis in zoos and aquariums and other animal facilities such as primate research centers, sanctuaries, and rescue centers.Keywords Animal training . Animal welfare . Aquariums . Behavior analysis . Environmental enrichment . Zoo biology . ZoosPsychologists trained in behavior analysis have a long history of conducting basic and applied research with exotic wildlife in zoos, aquariums, and specialized marine parks. At one time, operant conditioning techniques were routinely deployed to train cetaceans (dolphins and porpoises) in studies of discrimination, sensory perception, and echolocation (Kellogg and Rice 1966;Pryor 1981;Tavolga 1966). Many studies of cetaceans and pinnipeds (seals, sea lions, walrus) have been published in psychology journals, including the

“…Furthermore, food is commonly presented in a ready-processed form, which further reduces the need to forage [Morgan and Tromborg, 2007]. As a consequence, captive animals spend less time foraging and feeding than their wild counterparts [Britt, 1998;Lukas, 1999;Höhn et al, 2000;Kerridge, 2005]. At the spatial level, although the benefits of scattering food in the substrate have been recognized for several decades, food is often delivered in predictable locations in containers that represent discrete monopolizable food clumps [Anderson and Chamove, 1984;Forthman et al, 1992;Swaisgood and Shepherdson, 2005].…”

The presentation of food may affect feeding competition and the well-being of captive social species. We hypothesized that feeding competition in a captive group of 5 black-handed spider monkeys (Ateles geoffroyi) should increase in response to certain food presentations in terms of size, distribution and quality of food, and that higher feeding competition should lead to an increase in agonism and physiological stress (measured by faecal glucocorticoid metabolites, FGCM) as well as to a decrease in affiliation, proximity among individuals and feeding activity. We used 5 experimental treatments representing different combinations of size, distribution and quality of food. We observed social interactions for 100 h, collected 6,500 proximity and feeding activity records, and gathered 226 faecal samples. When food was clumped, individuals spent less time feeding, and there was also significant individual variation in feeding activity within treatments. FGCM levels were higher when food was clumped. These results are probably linked to an increase in feeding competition when food is concentrated. At least in small groups of spider monkeys, dispersing food in two feeding stations may be sufficient to decrease differences among individuals in priority of access to food resources, hence reducing physiological stress and interindividual differences in feeding activity.
