Mothers transfer information via eggs: effect of mothers' experience with predators on offspring
… the fry were measured. Shoaling behavior, an antipredator response, was measured from photographs, and was estimated as the nearest neighbor distance between individuals in each tank. Experimental females shoaled more tightly together prior to a mild disturbance. Both control and experimental …

Costs and benefits of Daphnia antipredator behavior and consequences on community stability
… energy flow caused by costs and benefits of antipredator defenses and to study their implications for community stability, I used the planktivorous fish - Chaoborus - Daphnia system. In the laboratory, I found that clonal variance of Daphnia antipredator defenses was high, and that …

The role of embryonic risk cues on the life history, morphology and behaviour of the wood frog Lithobates sylvaticus
… disturbance cues also caused a decrease in response to larval alarm cues. Neither cue caused a change in morphology. Wood frog embryos can produce disturbance cues. These cues as well as embryonic alarm cues are used by embryos to assess the risk in their environment and produce a response …

Two Layers of Selfish-Herds in Spawning Aggregations of Chub (Nocomis Sp.) and its Nest Associates
Many species have evolved to live in groups. Gregarious behavior was believed to be adaptive for whole-population survival and predator evasion until selfish-herd theory was introduced. It proposed that individuals congregate not as a method of protection for the entire population, but instead to …

Driving giants: spatial and temporal variables influencing giraffe movements in a private protected area
… strategies. The fear of predation prompts antipredator responses in prey which include vigilance behavior, grouping, and shifts in habitat selection. However, these responses may incur costs, impacting energy expenditure of prey and time allocation of prey activities such as foraging, …
