In situ examination of boldness-shyness traits in the tropical poeciliid, Brachyraphis episcopi
Article Abstract:
A study examining the boldness in a situ experiments with fishes from eight populations of the poeciliid Brachyraphis episcopi from high- and low-predation area within four streams that run independently into the Panama Canal to define personality traits is the shyness-boldness continuum was executed. The results revealed that boldness scores were strongly influenced by standard length and the relative level of predation pressure in rivers and in all four rivers fish from high-predation areas were bolder than those in low-perditions areas and the fishes became shy as they grew.

Behavioral responses by slugs to chemicals from a generalist predator
Article Abstract:
A study is investigated to know whether Deroceras reticulatum adopts antipredator behaviors towards a generalist predator, by testing the null hypothesis that the slugs do not respond to residual Pterostichus melanarius chemicals. It is concluded that slugs have evolved behavioral responses to chemical cues from either the generalist carabid predator in particular, or carabid beetles generally, many species of which include molluscs in their diets.

Predator - induced plasticity in web - building behavior
Article Abstract:
A study is conducted to examine web-building responses of the St. Andrew cross spider, Argiope versicolor, to predation risk from the jumping spider, Portia labiata. The study shows that the Argiope versicolor can detect and differentiate between predators and non-predators through olfactory cues and induce plasticity in web-building in response to the predation risk.
