2021-01-07ZeitschriftenartikelConsistent Behavioral Syndrome Across Seasons in an Invasive Freshwater Fish Lukas, Juliane; Kalinkat, Gregor; Miesen, Friedrich Wilhelm; Landgraf, Tim; Krause, Jens; Bierbach, DavidUnderstanding the linkage between behavioral types and dispersal tendency has become a pressing issue in light of global change and biological invasions. Here, we explore whether dispersing individuals exhibit behavioral ...

2021-03-18ZeitschriftenartikelDiurnal Changes in Hypoxia Shape Predator-Prey Interaction in a Bird-Fish System Lukas, Juliane; Auer, Felix; Goldhammer, Tobias; Krause, Jens; Romanczuk, Pawel; Klamser, Pascal; Arias-Rodriguez, Lenin; Bierbach, DavidAnimals often face changing environments, and behavioral flexibility allows them to rapidly and adaptively respond to abiotic factors that vary more or less regularly. However, abiotic factors that affect prey species do ...

2020-05-15ZeitschriftenartikelGuppies Prefer to Follow Large (Robot) Leaders Irrespective of Own Size Bierbach, David; Mönck, Hauke J.; Lukas, Juliane; Habedank, Marie; Romanczuk, Pawel; Landgraf, Tim; Krause, JensBody size is often assumed to determine how successfully an individual can lead others with larger individuals being better leaders than smaller ones. But even if larger individuals are more readily followed, body size ...

2021-09-15ZeitschriftenartikelImpact of Variable Speed on Collective Movement of Animal Groups Klamser, Pascal; Gómez-Nava, Luis; Landgraf, Tim; Jolles, Jolle; Bierbach, David; Romanczuk, PawelThe collective dynamics and structure of animal groups has attracted the attention of scientists across a broad range of fields. A variety of agent-based models have been developed to help understand the emergence of ...

2018-02-05ZeitschriftenartikelInsights into the Social Behavior of Surface and Cave-Dwelling Fish (Poecilia mexicana) in Light and Darkness through the Use of a Biomimetic Robot Bierbach, David; Lukas, Juliane; Bergmann, Anja; Elsner, Kristiane; Höhne, Leander; Weber, Christiane; Weimar, Nils; Arias-Rodriguez, Lenin; Mönck, Hauke J.; Nguyen, Hai; Romanczuk, Pawel; Landgraf, Tim; Krause, JensBiomimetic robots (BRs) are becoming more common in behavioral research and, if they are accepted as conspecifics, allow for new forms of experimental manipulations of social interactions. Nevertheless, it is often not ...

2021-02-12ZeitschriftenartikelMale Sexual Preference for Female Swimming Activity in the Guppy (Poecilia reticulata) Bierbach, David; Wenchel, Ronja; Gehrig, Stefan; Wersing, Serafina; O’Connor, Olivia L.; Krause, JensMate choice that is based on behavioural traits is a common feature in the animal kingdom. Using the Trinidadian guppy, a species with mutual mate choice, we investigated whether males use female swimming activity—a ...

2021-10-04ZeitschriftenartikelParasite infection impairs the shoaling behaviour of uninfected shoal members under predator attack Demandt, Nicolle; Bierbach, David; Kurvers, Ralf H. J. M.; Krause, Jens; Kurtz, Joachim; Scharsack, Jörn PeterA key benefit of sociality is a reduction in predation risk. Cohesive group behaviour and rapid collective decision making are essential for reducing predation risk in groups. Parasite infection might reduce an individuals’ ...

2021-02-04ZeitschriftenartikelSize Selective Harvesting Does Not Result in Reproductive Isolation among Experimental Lines of Zebrafish, Danio rerio: Implications for Managing Harvest-Induced Evolution Roy, Tamal; Fromm, Kim; Sbragaglia, Valerio; Bierbach, David; Arlinghaus, RobertMortality in fish populations is commonly size-selective. In fisheries, larger fish are preferentially caught while natural predators preferentially consume smaller fish. Removal of certain sized fish from populations and ...
