resources; adjusting aggression levels according to context is key to avoid negative …

Given the dramatic increase in the L. sceleratus population in the southeastern Aegean Sea,
there is growing interest in assessing the toxicity of this pufferfish and the factors controlling …

plasma steroid hormone concentrations with subsequent impacts on reproductive …

Simple Summary Environmental pollution and hydropower development have affected fish
survival and caused the extinction of some fish populations and species. To understand the …

Habitat degradation not only disrupts habitat‐forming species, but alters the sensory
landscape within which most species must balance behavioural activities against predation …

The role of hormones as modulators of aggressive behavior in fish remains poorly
understood. Androgens and corticosteroids, in particular, have been associated with …

Animals with similar fighting ability can fight harder and longer than animals in asymmetric
contests. Thus, the selection of fish by size similarity in husbandry might increase aggressive …

Fishes have radiated throughout all aquatic environments, and this is reflected in an
extraordinary diversity of mating systems and reproductive behaviors. Many species present …

Androgens respond to social challenges and this response has been interpreted as a way
