Lanchester battles and the evolution of combat in ants
Article Abstract:
Lanchester's two models of combat are applied toants. Two different types of battle strategy develops from these two models. Ifthe attacking side is in the majority, it should try to fight by using its numerical superiority to minimize casualties. If the attacking side is in the minority, it must fight a series of one-to-one duels. These two models exactly predict battle strategies in two groups of ants that regularly engage in battles, and they are the army ants and the slave-makers. Moreover, these models can be used to predict the dynamics and outcome of a given battle.

Egg-dumping lace bugs preferentially oviposit with kin
Article Abstract:
It is uncertain if egg dumpers discriminate among kin and nonkin egg recipients. Some female lace bugs, Gargaphia solani, with eggs will accept and defend eggs of conspecifics. Egg dumpers were examined to determine if they preferentially dump their eggs with unguarded eggs of kin or nonkin. Most eggs were dumped with full siblings' eggs and egg dumpers were likely to oviposit among eggs of kin with whom they interact.

Absence of joint nesting advantage in desert seed harvester ants: evidence from a field experiment
Article Abstract:
Assessment of single and double foundress colony associations of the desert seed harvester ants revealed survival rates of ants in single or double foundress colonies to be almost equal, thereby revealing the lack of any benefits of joint nesting in this species. Nesting in the vicinity of mature colonies is ascertained to be a response to good food availability in these locations.
