Differential responses of yellow-breasted chats, Icteria virens, to male and female conspecific model presentations
Article Abstract:
The extrterritorial intrusions were simulated by presenting conspecific models on to territories of a Neotropical migratory passerine, the yellow-breasted chat, Icteria virens. The results of this study revealed that territorial aggression in yellow-breasted chats is strongly intrasexual, and simulated female extraterritorial intrusions resulted in extrapair courtship and copulation, rather than male intrusions.

Seoul virus infection increases aggressive behavior in male Norway rats
Article Abstract:
The Hantavirus infection that causes an increase in aggression in male rats is determined. Determination of whether behavioral changes are due to infection of the central nervous system or peripheral tissues is done which showed that Seoul virus did not alter either testosterone or corticosterone concentrations.
