In situ examination of boldness-shyness traits in the tropical poeciliid, Brachyraphis episcopi (2005, background): “For example, individuals may differ in how they respond to mild stressors, which may in turn affect their propensity to explore novel environments (Brown & Braithwaite 2005).”
The influence of early experience on, and inheritance of, cerebral lateralization (2007, unknown): “The predation regime these fish live under has a substantial bearing on a number of traits including life history, spatial-learning abilities, boldness and stress responses (Jennions & Telford 2002; Brown & Braithwaite 2004, 2005; Brown et al. 2005a, b).”
Short-range orientation in fish: How fish map space (2006, background): “Recently, however, independent observations on a different species of fish have shown that the level of predation pressure can affect its spatial behaviour (Brown and Braithwaite 2005).”
Hastiness, brain size and predation regime affect the performance of wild guppies in a spatial memory task (2008, background): “Why then the differences between our results and those of Brown & Braithwaite (2005)? Brown & Braithwaite (2005) suggested that high-predation B. episcopi made more exploratory searches of incorrect chambers, perhaps due to different priorities of highand low-predation fish.”
