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 ...

Their wanderings were not as aimless as they appeared, for they were quartering
the ground very thoroughly like a pack of hunting-dogs, investigating every bit of
the terrain over which their army would have to travel. The black ants seemed
distinctly ill at ease. Occasionally one of them would meet one of the slave-
makers and would turn tail and run back to the nest to join one of the many
groups of his relatives who were gathered in little knots, apparently holding a
council of war.

Furthermore, Leptothorax longispinosus (host) colonies in the vicinity of
Protomognathus americanus (slave-maker) colonies are less polygynous, have
higher relatedness and also fewer workers compared with host colonies away
from slavemakers. The fact that slave colonies contain host workers which are
genetically more diverse than workers ir1 the neighbouring colonies may simply
result from raids on multiple-host colonies. The similarities between these studies
and ours are ...

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.
