Examples of Animal Behavior Research
Animal behavior research can involve a wide range of animal species and research subjects. In ethology, animal behavior is studied under natural conditions. Ethology has its roots in the scientific work of Charles Darwin (1809-1882), as well as Dutch biologist Nikolaas Tinbergen (1907-1988).
Ethology combines laboratory and field science, and also has strong relations to other disciplines, such as neuroanatomy, ecology, and evolutionary biology. Researchers in this field of study are interested in understanding the functions, causes, development, and evolution of animal behavior.
In this blog post we describe several examples of animal behavior research. Want to read even more? Please visit our Behavioral Research Blog!
Neuroscience research with guinea pigs
According to Kiera-Nicole Lee and her colleagues, guinea pigs differ from mice and rats, and that just might make them more suitable for some neuroscientific studies. This is due to the fact that results from studies with guinea pigs are more easily translated to humans.

Domesticated vs wild animals
Not many studies have compared the behaviors of wild and domesticated animals. When they do, such as with guinea pigs, they mostly compare adults.
Zipser et al. were curious to find out whether the differences in behavior between domesticated guinea pigs and the wild cavies were also found earlier on, and so they compared these species during the early and late phase of adolescence.

Chicken welfare
There are almost 100 million chickens in the Netherlands — that's about 17 times as many chickens as people. Their welfare has improved enormously in the past few years, but there is still plenty of room for improvement.
In the ChickenStress project, we work with different partners to improve chicken welfare and reduce problems like feather pecking.

Spatial behaviors in sheep
There is still a lot to learn about the behavioral and social patterns in sheep. The more we understand, the better we can improve the health and welfare of these livestock animals. At the Aberystwyth University in Wales, UK, researchers used TrackLab for tracking and detailed analysis of spatial behaviors in sheep.

A rat model for Parkinson's disease
Parkinson’s disease is a neurodegenerative disorder that affects mobility in a life-changing way. Slow movement, shuffling of the feet, and difficulties initiating movement are all impairments we recognize as typical for this disease.
Researchers Jordi Boix and his colleagues, from the University of Auckland in New Zealand, used two rat models to investigate a number of gait parameters. Their aim was to find resemblance to human symptoms, and to specifically find them early on.

Zebrafish studies
Teresa Capriello and her colleagues from the University of Naples have found something fishy about the effects of cadmium and aluminum on behavior. The team uses zebrafish to study the neuronal mechanisms of these heavy metals in connection to neurodegenerative and neuromuscular diseases.

How fruit flies find your food (and mates!)
Those tiny flies that take over your garbage cans in the summer? They are called fruit flies for a reason! They have a fantastic sense of smell and these creatures are a popular animal model for researchers.
Find out what researchers discovered about fruit flies and their smell.
Interactive enrichment for great apes
There is growing empirical support demonstrating improved welfare in captive animals when they can exert control over their environment. Research shows that great apes can successfully interact with digital media devices and can demonstrate behavioral changes when presented with digital enrichments.
Nicky Kim-McCormack and her colleagues from Australian National University studied the effects of digital enrichment on animal welfare. They included Seoul Zoo’s six orangutans and four chimpanzees in their study.

Observing monkey behavior and their use of tools
We already know some monkeys display above average intelligence. Behavioral studies have shown that capuchin monkeys use tools suck as boulders and logs as anvils upon which they can crush nuts. Fragaszy et al. studied a group of wild capuchin monkeys in Brazil, specifically the placement of nuts prior to striking them. An interesting detail: they studied this same behavior in humans as well.

How to monitor rat social behavior
Monitoring and analyzing the social behavior of group housed rodents is something that many researchers find extremely challenging. It can also be very time consuming. However, including social behavior as part of a phenotypic screen has important benefits, and eventually leads to better translational value of rodent models. During her PhD research, Suzanne Peters developed an automated analysis that allows for the monitoring of socially interacting rats.

Insect damage on leaves changes the reproductive strategy of plants
We all know that the majority of plant species depends on pollinators, like bees and syrphid flies, for reproduction. What most of us do not know is that this process is far more complex than it looks at first sight.
Stereotypical effects on cognitive bias
Stressed-induced stereotypical behavior in lab mice have different effects on cognition. The radial arm maze is often used to investigate this.
