Learned social preference in zebrafish

25.05.2004


Using the zebrafish, a model organism widely used in genetic studies, researchers have found that when it comes to social interactions with other fish, individual zebrafish learn to prefer one fish color pattern over another according to their early experience with these patterns. The work extends the utility of zebrafish to studies of behavior and evolution and is reported by University of Texas researchers Raymond E. Engeszer, Dr. David M. Parichy, and Dr. Michael J. Ryan.



Social behavior has long been of interest to biologists and psychologists alike. The studies reported this week suggest that the extensive knowledge of zebrafish genetics will afford researchers an opportunity to see how genes, development, and environment lead to behaviors that mediate social interactions.

The investigators examined the way fish choose their consorts during the formation of loose social aggregates, called shoals, and they exploited the developmental genetic resources of this biomedical model organism to manipulate the appearance of the fish. Fish were chosen to have drastically different color patterns, either blue and gold stripes or an absence of stripes and a uniform mother-of-pearl color. This difference was the result of a single DNA base change in the fish’s genome. To determine whether genes or the environment determine individuals’ preferences, the investigators raised subject fish either with other fish of their own color or with fish of the alternate color. When subject fish were later allowed to choose which color of fish to associate with, they greatly preferred whichever color pattern they had been raised with, irrespective of their own color. This learned social preference could have enormous impacts on the survival and reproductive success of individual fish. This work represents a first step in using the zebrafish and the tools of developmental genetics to investigate long-standing questions concerning the impact of behavior on evolution.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
