Contrafreeloading (CFL) is a concept that describes the preference of an animal to work for food even when identical food is freely available, and reflects an intrinsic motivation to engage in foraging-related activities. However, altered...
In a highly social species like chimpanzees, the process by which individuals become attuned to their social environment may be of vital importance to their chances of survival. Typically, this socialization process, defined by all...
Birds are highly social and must be paired in order to increase their welfare. Most bird species are monomorphic; therefore, molecular sexing helps provide appropriate welfare for birds. Moreover, early sex determination can be of...
Applying principles of foraging ecology to zoo-housed animals can positively influence animal behavior, and assist with evaluating exhibit space and design. In this study, we implemented zoo foraging ecology by measuring giving-up densities (GUDs) in...
Neophobia, the fear of novelty, is an ecologically important response which enables animals to avoid potentially harmful situations. Neophobia is a cognitive process by which individuals distinguish novelty from familiarity. In this study, we aimed...
Background: Rabbits are common companion animals in many European countries. Rabbit-assisted interventions in primary schools are suitable for decreasing the anxiety levels of children, which may increase the education efficiency of teachers. Methods: In our...
Although historically understudied, the empirical evaluation of captive reptile welfare is becoming more common, and zoos continue making modifications to their reptile facilities with the goal of improving welfare. In this study, we evaluated the...
A wide variety of fish species have been displayed in public aquariums and zoological collections for over 150 years. Though the issue of pain perception in fish is still being debated, there is no disagreement...
Although the use of fecal glucocorticoid metabolite (FGCM) measurements as non-invasive biomarkers for the stress response in mammals has increased, few studies have been conducted in odontocetes. We investigated if animal sex, age, pregnancy or...
Breathing frequency is a non-invasive physiological measure that brings valuable information on the bottlenose dolphins’ internal state and behaviors. When combined with behavioral observations, it helps to better understand and interpret relevant behaviors. The present...
