- Temperament in bullheads: do laboratory and field explorative behaviour variables correlate?Alexander Kobler
Ethology Research Group, Department of Biology, Campus Drie Eiken, University of Antwerp, Universiteitsplein 1, Wilrijk, Antwerp, Belgium
Naturwissenschaften 96:1229-33. 2009..However, overall, our results illustrate that exploration rate of bullheads in isolated single-individual experiments can be used to predict this behaviour in the natural ecosystem...
- Coexistence of behavioural types in an aquatic top predator: a response to resource limitation?Alexander Kobler
Department of Biology and Ecology of Fishes, Leibniz Institute of Freshwater Ecology and Inland Fisheries, Müggelseedamm 310, 12587 Berlin, Germany
Oecologia 161:837-47. 2009..We conclude that behavioural diversification in habitat use and activity reduces intraspecific competition in preferred littoral habitats. This may facilitate the emergence of an ideal free distribution of pike along resource gradients...
