Agonistic behavior of <i>Peromyscus leucopus</i> and <i>Microtus pennsylvanicus</i>: implications for population distribution and dynamics
<p>It is hypothesized that interspecific aggression between <em>Peromyscus leucopus</em> and <em>Microtus pennsylvanicus</em> influences levels of ACTH, and thus depresses the reproductive potential of one or both species. Exposure of maturing young to interspecific aggression might be especially …

Comparative reproductive biology of co-occurring endangered and common shrubland birds
… trials (n = 16) to test for the presence of interspecific aggression. White-eyed vireos arrived first and established territories in shrub and woodland habitat with equal probability. Black-capped vireos arrive after white-eyed vireos and settled in greater numbers in shrubland habitat. …

Behavioural interactions and reasons for aggression between Australian magpies (Gymnorhina tibicen) and other birds in New Zealand
… and (2) examine potential explanations for the interspecific aggression displayed by magpies. Accounts of magpie attacks on birds in New Zealand were collated from literature and a survey of the public, and then summarised to identify the frequency and characteristics of reported attacks on …

Intraspecific and Interspecific Agonistic Behavior in Chipmunks, TAMIAS MERRIAMI, T. OBSCURUS, and T. SPECIOSUS (Rodentia: Sciuridae)
… present. T. merriami showed the most intra- and interspecific aggression, followed by T. obscurus, then T. speciosus. Dominance hierarchies were determined at three sites. There were some dominance reversals in both T. merriami and T. obscurus. No correlation was found between dominance and size, …

Is meadowlark habitat segregation within sympatry behaviorally mediated?
… beyond simple habitat relationships, such as interspecific competition. Within sympatry, Eastern and Western Meadowlarks establish and maintain mutually exclusive, multi-use territories. However, the influence this aggressive behavior may have on ecological relationships between these species …

Effects of interspecific competition, salinity, and hurricanes on the success of an invasive fish, the Rio Grande cichlid (Herichthys cyanoguttatus)
… significant effect on H. cyanoguttatus growth. Interspecific behavioral experiments were conducted to examine potential biotic interactions with native fish species. Prior resident trials indicated that H. cyanoguttatus was aggressive whether holding territory or not, and that native bluegill …

The ecology of the Red-vented Bulbul in Fiji.
… secondary vegetation in the forests. Very little interspecific aggression involving the Bulbul and indigenous birds was observed and there appears to be little scope for direct competition for food resources between introduced and native species. Only the Polynesian Starling, Aplon.is tahuensis …
