Evaluating recovery strategies for an ocelot () population in the united states
The ocelot Leopardus pardalis population in the United States was listed as endangered in 1982, with only two known isolated breeding populations occurring in southern Texas. Conservation concerns for ocelots include loss of dense thornshrub habitat, mortality from ocelot-vehicle collisions, and genetic erosion. In this study, we used a population viability analysis (PVA) to evaluate […]
“Separation/Abandonment/Isolation Trauma:” What We Can Learn From Our Nonhuman Primate Relatives
Building upon my prior work exploring the impact of childhood abandonment and isolation on chimpanzees and humans, this article discusses the relevance of nonhuman primate research to our understanding of this phenomenon in children. Both laboratory research and naturalistic studies have confirmed the strong commonalities in parenting between our 2 species and have reached similar […]
Assessment of different stunning methods and recovery of farmed Atlantic salmon (Salmo salar): isoeugenol, nitrogen and three levels of carbon dioxide
Isoeugenol (17 mg L–1), nitrogen, and three levels of carbon dioxide (low: 70–80, medium: 180–250 and high: > 400 mg CO2 L–1) were tested as stunning agents for Atlantic salmon (Salmo salar) fasted for six days. All methods were tested under optimised conditions (starting with rested fish, and stunning and recovery under good water quality […]
Does environmental enrichment promote recovery from stress in rainbow trout?
The EU Directive on animal experimentation suggests that all protected animals should have enrichment to improve welfare yet relatively little research has been conducted on the impact of enrichment in fish. Studies employing enrichment in zebrafish have been contradictory and all fish species should be provided with species-specific enrichments relevant to their ecology. Salmonids are […]
Assessment of behavior and space use before and after forelimb amputation in a zoo-housed chimpanzee (Pan troglodytes)
Primates possess great manual dexterity, and their limbs are integral to many aspects of normal functioning (e.g., climbing, feeding). As such, the loss of a limb carries the risk of significant disability and potentially harmful impairment of species-typical functioning. Limb loss is known to occur in some wild primate populations due to entanglement in hunting […]
A new method of walking rehabilitation using cognitive tasks in an adult chimpanzee (Pan troglodytes) with a disability: a case study
There are few studies of long-term care and rehabilitation of animals which acquired physical disabilities in captivity, despite their importance for welfare. An adult male chimpanzee named Reo at the Primate Research Institute of Kyoto University, developed acute myelitis, inflammation of the spinal cord, which resulted in impaired leg function. This report describes a walking […]
The impact of social context on behaviour and the recovery from welfare challenges in zebrafish, Danio rerio
Understanding how animals experience stress in a laboratory environment is crucial for improving their welfare. Increasing numbers of fish are being used in scientific studies and further research is required to ensure appropriate conditions are used to promote good conduct and correct housing as well as guaranteeing scientifically valid results. As zebrafish are a gregarious […]
