Does tiger shark predation risk influence foraging habitat use by bottlenose dolphins at multiple spatial scales?
Article Abstract:
The influence of prey abundance and tiger shark predation risk on Indian Ocean bottlenose dolphin habitat use across multiple spatial scales, in Shark Bay, Western Australia is investigated. It is found that predation risk and prey availability influence dolphin habitat use at multiple spatial scales but predator encounter rate as well as intrinsic habitat risk is important in shaping dolphin space use decisions.

Body, shape, burst speed and escape behavior of larval anurans
Article Abstract:
Variation in behavior, morphology and history traits of larval anurans across predator gradients, and consequences of that variation are studied. The analysis of morphology and burst speed defined a shared axis of shape variation associated with burst-swimming speed regardless of species and tadpoles with a deeper tail fin, muscle and a smaller body produced faster speeds.
