Among vertebrates, defensive behaviours have been reviewed for fishes, salamanders, reptiles, birds, and mammals, but not yet for anuran amphibians. Although several defensive strategies have been reported for anurans, ...

This study explores the dynamical behaviour of electromechanical systems used as vibration absorber. A nonlinear system is considered, with the nonlinearity coming from Duffing-type stiffness. The mathematical modelling ...

This study examines the influence of early experience with different forms of aggressive behaviour on the fighting behaviour of young fish. Fry of the cichlid fish, Oreochromis niloticus, were raised from hatching in small ...

Classical models for biological invasions were single-species models in homogeneous landscapes, but most invasions happen in the presence of interacting species and in heterogeneous environments. The combination of spatial ...

Trace elements are an omnipresent group of chemical elements that are found practically in all types of environments sustaining life. Since its principal characteristic is the very low concentration in ground and water, ...
