Environmental Enrichment: a gap analysis for captive animals
Environmental Enrichment, captive animals, gap analysis.
Environmental enrichment is a management principle aimed at meeting the needs of
the captive animal, identifying and providing essential environmental stimuli for its
psychological and physiological well-being. Space is often used to improve the quality of life
of the animal under human care and to avoid abnormal and stereotyped behaviors. Thus, the
objective of this study is to evaluate, through a bibliometric analysis, the scenario of studies on
environmental enrichment in animals kept under human care around the world in the last 17
years, verifying whether the gaps pointed out by Azevedo et al. (2007) were fulfilled. In
addition, this bibliometric review will allow identifying new gaps in knowledge about
environmental enrichment, quantifying the main types of environmental enrichment offered to
animals, the main methods of evaluating its efficiency, the places where studies are most
carried out, the most productive authors on the subject and the animal species used as study
models.
