Individuals of gregarious species often group with conspecifics to which they are
phenotypically similar. This among-group assortment has been studied for body size, sex …

Position in a dominance hierarchy profoundly impacts group members' survival, health, and
reproductive success. Thus, understanding the mechanisms that regulate or are associated …

In high-risk environments with frequent predator encounters, efficient antipredator behavior
is key to survival. Parental effects are a powerful mechanism to prepare offspring for coping …

Exposure to repetitive startling stimuli induces habitation, a simple form of learning. Despite
its simplicity, the precise cellular mechanisms by which repeated stimulation converts a …

Sensory experiences dynamically modify whether animals respond to a given stimulus, but it
is unclear how innate behavioral thresholds are established. Here, we identify molecular …

We review the influence of context on behavioral choice. Context can refer to external
(environmental) factors such as the season or presence of predators and it can also refer to …

The Mauthner-cell (M-cell) system of teleost fish has a long history as an experimental
model for addressing a wide range of neurobiological questions. Principles derived from …

Social life affects brain function at all levels, including gene expression, neurochemical
balance, and neural circuits. We have previously shown that in the cichlid fish Astatotilapia …

Social plasticity, defined as the ability to adaptively change the expression of social behavior
according to previous experience and to social context, is a key ecological performance trait …

In a social group, animals make behavioral decisions that fit their social ranks. These
behavioral choices are dependent on the various social cues experienced during social …
