Environmental enrichment affects the complexity and length of the dendrite arbors (upon which synapses form). Higher-order dendrite branch complexity is increased in enriched environments, [13] [15] as can the length, in young animals, of distal branches. [16] Environmental enrichment rescues harmful effects of stress on dendritic complexity. [17]
Environmental enrichment can improve the overall welfare of animals in captivity and create a habitat similar to what they would experience in their wild environment. It aims to maintain an animal's physical and psychological health by increasing the range or number of species-specific behaviors, increasing positive interaction with the captive environment, preventing or reducing the frequency ...
Animals placed in an enriched environment had heavier, thicker cortexes and an increase in the number of dendritic branches (including oblique dendrites) in the hippocampus than the standard or impoverished condition. [1] [2] This phenomenon is known as neuroplasticity.
Most of the research on environmental enrichment has been carried out on non human animals. [2] In an experiment, four different habitats were set up to test how environmental enrichment or relative impoverishment affected rats' performance on various measures of intelligent behavior. First, rats were isolated, each to its own cage.
Many who keep animals in captivity attempt to prevent or decrease stereotypical behavior by introducing stimuli, a process known as environmental enrichment. The goals of environmental enrichment are to make environments more complex and fluid, offer more engaging and complex processes, and give animals more chances to make decisions.
Training animals to voluntarily co-operate with procedures (e.g. blood sampling) so that they have greater control over the procedure reduce distress; Provision of species-appropriate housing and environmental enrichment which meet the animals' physical and behavioural needs (e.g. providing opportunities for nesting for rodents)
In 2017, the People for the Ethical Treatment of Animals (PETA) sued the Missouri Primate Foundation, alleging that chimpanzees at the foundation, including Tonka, were kept in unsanitary living ...
Zookeepers with a cheetah at Australia Zoo.. A zookeeper's responsibilities usually include feeding, maintaining and cleaning the animals, diet preparation, behavioral observation, record keeping, exhibit maintenance and providing environmental enrichment for the animals in their care. [3]
