Social learning in noncolonial insects?

08.11.2005


Social learning and use of social information in general have been understood to be largely restricted to vertebrates. Among insects, social learning or processes akin to it have been reported only in colonial species (bees, ants, termites), suggesting that highly structured social organizations may have assisted the evolution of social learning. However, learning about predators or predation risk from others may constitute life-saving information, and not just in vertebrates or colonial insects. Theory predicts that social acquisition of such information should therefore have been evolutionarily favored in any species where members of that species can observe each other and behave differently under conditions of predation risk.



Researchers Isabelle Coolen, Olivier Dangles, and Jérôme Casas, from the University of Tours, France, considered that wood crickets might be just the candidate to test for this prediction. Indeed, wood crickets typically hide under leaves when in the presence of spiders, and the high local densities at which they live may well allow for social transmission of information regarding danger.

In the new work in the journal Current Biology, the authors found that not only do crickets hide more when in the presence of others who have just experienced a dangerous environment, but they also continue to do so long after these "demonstrators" are gone. The authors showed that the long-lasting behavioral changes cannot be simply attributed to such nonsocial factors as long re-emergence times or residual odor cues, and that the most straightforward explanation for the observed behavioral changes is one involving social learning. The findings of Dr. Coolen and colleagues therefore question the common conception that social learning is restricted to large-brained animals assumed to possess superior cognitive abilities.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
