Disentangling the contribution of the attacker from that of defender in the differences in the intraspecific fighting in two species of voles

Article Abstract:

Studies of intraspecific fighting in two species of voles show that prairie vole resident males attacked the head instead of the rear if the defender turned to face the attacker, but montane vole resident males continued to attack the defender's rear. Videorecorded tapes of defensive and offensive behavior of both vole species were analyzed in depth. The study also revealed that defensive prairie voles retreated after each ineffective defense. Montane voles, however, faced their attackers tenaciously.

Supine defense in the intraspecific fighting of male house mice Mus domesticus

Article Abstract:

Experiments were conducted to study the use of supine behavior as a defensive ploy in male house mice Mus Domesticus. Results indicated that this maneuver is used by mice to prevent attacking opponent from biting them in the region of the lower dorsum. Supine behavior is, therefore, not a submissive tactic but is a dynamic defensive behavior to protect specific areas of the body. The mice do not remain in this position for long, but immediately return to prone position and flee.

Analysis of the targets and tactics of conspecific attack and predatory attack in northern grasshopper mice onychomys leucogaster

Article Abstract:

A study is made of the fighting/defending tactics and the specific target of attack of the northern grasshopper mice onychomys leucogaster to determine patterns or contextual rules which govern the use of fighting tactics. Results show that the grasshopper mice, which is a very aggressive species, favor the bilateral attack most in fighting/defending an upright defensive posture taken by opponents.
