The predation hypothesis is unlikely to be a complete explanation, since the ants
in the various phylogenetic lines in which slave makers occur are not strongly
predatory and do not attack other ant colonies as a major component of their
foraging strategies (but see Topoff, 1991, for a possible exception). None the less
, opportunistic brood predation as a result of territorial interactions is relatively
common in these groups (Wilson, 1975b, Alloway, 1980; Stuart and Alloway,
1982, 1983).

of hierarchical relations among foragers of a mixed colony of F. sanguinea
suggested a higher hierarchical status for the slavemakers (Harkiv, 1985). But in
our experiments we chose mainly more active, highly mobile ants. Individual
labeling of these ants and subsequent observation of their behaviour in the arena
did not reveal significant differences in their hierarchical status. This suggests
that, in mixed groups, the observed preferences in trophollaxis and antennal
contacts are ...

Leptotlzorax longispinosus workers from Vermont and New York populations

behaviour a higher proportion of Pratomognat/tux americanus workers were

Thus, the slave-makers are more analagous to a "pursuing" predator than to a "
searching" predator, in Mac- Arthur and Pianka's (1966) terminology. We should
therefore expect some kind of specialization: either macrohabitat or microhabitat
niche breadths, or both should be narrow if efficiency of colony capture is
maximized. Specialization is unlikely to be based on separate slave species
because several enslaved species such as Formica fusca are known from nearly
all ...

In the Formicinae, species of the Formica sanguinea group are facultative
slavemakers and those of the genera Polyergus and Rossomyrmex, obligate
slavemakers. We tested three hypotheses: (1) The more frequent slavery is in a
species, the higher the proportion of slaves, and thus (2) the slaves should
feature as an extra caste within the nest of the slavemaker. (3) Those formicine
slavemakers that virtually always have slaves, are obligate slavemakers. In FJk

The Slavemakers One of the most interesting developments in ant evolution is
that of the slavemaker ants. These species raid the nests of other ants and make
off with the pupae. When the adults of the slave species emerge from the pupae,
they accept the slavemakers as nest mates and work as hard for them as they
would for their own kind. Some slavemakers have become so completely
specialized as raiders that they are totally dependent on the slaves for their
everyday needs.

We tested that assumption by comparing the summertime seasonal productivity
of Leptothorax spp. colonies in field exclosures without slavemakers, with a
colony of the obligatory slave-making ant Protomognathus americanus, or with a
colony of the obligatory slavemaker Leptothorax duloticus. Leptothorax
longispinosus colonies placed in exclosures with P. americanus colonies did not
differ significantly in any demographic attribute from colonies in exclosures
without slavemakers.
