- Importance of predator diet cues in responses of larval wood frogs to fish and invertebrate predatorsD P Chivers
Department of Biological Sciences, University of Maine, 5751 Murray Hall, Orono, Maine 04469 5751, USA
J Chem Ecol 27:45-51. 2001..Predator diet effects are not ubiquitous in predator-prey systems. We discuss possible reasons why predator diet effects are seen in some, but not all, predator-prey systems...
- Avoidance response of juvenile Pacific treefrogs to chemical cues of introduced predatory bullfrogsD P Chivers
Department of Biology, University of Saskatchewan, Saskatoon
J Chem Ecol 27:1667-76. 2001..Additional experiments showed that both populations of treefrogs use chemical cues to mediate predation risk. Treefrogs from both populations avoided chemical alarm cues from injured conspecifics...

- Brook charr alevins alter timing of nest emergence in response to chemical cues from fish predatorsR S Mirza
Department of Biological Sciences, University of Maine, Orono 04469 5751, USA
J Chem Ecol 27:1775-85. 2001..Our results suggest that alevins that emerge sooner may escape predation in the redd, but may pay a cost in being under-developed upon emergence into the open water of the stream or lake...
- Chemosensory assessment of predation risk by slimy sculpins (Cottus cognatus): responses to alarm, disturbance, and predator cuesP J Bryer
Department of Biological Sciences, University of Maine, 5751 Murray Hall, Orono, ME 04469-5751, USA
J Chem Ecol 27:533-46. 2001..A histological analysis of the skin of sculpins revealed the presence of large sacciform cells that may act as the source of chemical alarm signals...
