Together with his co-author Marcel Brass, he explains why rule breaking is contagious and how knowledge about it can be used to prevent it. 22 December 2021 press release Why Mexican fish swim the Mexican wave Researchers at IGB have found that the Mexican waves collectively produced by tiny fish in Mexico actually reduce both their predatory birds' propensity to attack as well as the birds’ hunting success. Functionally, these waves may work as a signal from the fish to the birds: “We know you are there, don’t waste your time on attacking us!” 4 August 2021 short news Watch out – birds! How fish evade their predators If fish are hunted by birds, it is essential to their survival that they are able to recognise when they are in danger from avian predators. Juliane Lukas, Jens Krause and David Bierbach from IGB have investigated whether fish are able to differentiate between real danger and non-threatening events. 8 April 2021 short news Slowed down by parasites Many prey animals react collectively to predators. They transmit information about potential predators in no time at all to trigger and coordinate escape behaviours. Jens Krause and IGB guest scientist Ralf Kuvers, together with colleagues, found out that parasite infections can disrupt this transmission in a swarm. 14 January 2021 short news Invasion is independent of personality Researchers from IGB and the Zoological Research Museum Alexander Koenig studied guppies to investigate the linkage between behavioural types and dispersal tendencies – important for understanding biological invasions. 16 September 2020 press release You want to be a leader? You’ve got to be fast! David Bierbach and Jens Krause show that animals’ speed is fundamental for collective behavioral patterns, and that ultimately it is the faster individuals that have the strongest influence on group-level behavior. 29 July 2020 short news Lemon sharks – live fast, die young Risk-taking individuals are expected to grow better but also die faster than the less explorative individuals, according to the hypothesis that Félicie Dhellemmes and Jens Krause have tested. 25 July 2019 focus Big Fish = Bold Fish? An IGB study partially refutes the pace-of-life syndrome hypothesis. Ex-IGB doctoral student Giovanni Polverino, was able to show that the pace-of-life syndrome, much discussed in biology at present, does not appear under all conditions. 19 February 2019 press release Familiarity breeds aggression Aggressiveness among animals may increase the longer individuals live together in stable groups. This is the finding of a recent study carried out by researchers from IGB. The study, published in the journal Animal Behaviour used the Amazon molly to isolate the effects of familiarity on behaviour. 17 January 2019 short news Descendants of Phoenix Lesser Flamingos are the subject of a new book written by IGB scientist Lothar Krienitz. The book gives insights into the life of these mysterious water birds. Pagination First page « First Previous page ‹‹ Page 1 Current page 2 Page 3 Page 4 Next page ›› Last page Last »
