“…The need to perform a colony emigration is a contingency almost all species of ants can be expected to face (Wilson 1971 shading (Brian 1956, Carlson andGentry 1973), or climatic adversity such as drought or frost (Brian 1952). A colony may also be forced to emigrate because of some biotic factor such as inter-and intra-specific competition (H611dobler 1976, Waloff and Blackith 1962, Brian 1952, Brian et.…”

“…Colony growth may be restricted under smaller rocks due to a decrease in nesting area. The size of the nesting cavity (Waloff and Blackith, 1962;Carlson and Gentry, 1973;Smallwood, 1982), food supply (Mirenda andTopoff, 1980), competition (De Vita, 1979), the structural breakdown of nests (Wilson, 1971;Möglich, 1978;Foitzik and Heinze, 1998) and nest invasion (Brian, 1952;Waloff and Blackith, 1962;Brian et al, 1966).…”

The size of the nesting cavity and the nature of the nest-building material can constrain colony growth in eusocial insects. Rocks protect colony members against extreme temperatures as well as serve as a supplementary source of heat, thereby maintaining optimal conditions for brood development. The frequency distribution of available rocks and those occupied by colonies of Rhytidoponera metallica in the Avon River State Forest, Victoria, Australia, showed that colonies of R. metallica avoided nesting under small rocks (< 200 cm 2 ). A strong correlation between colony size and rock size indicates that nesting under a larger rock promotes colony growth. Laboratory choice experiments revealed that workers are capable of recognizing larger rocks from external physical characters (dimension). Field data indicates that colonies leave nests frequently, with nest abandonment peaking in the summer months.

“…In spring, the queen is often at the top of the nest, and thus vulnerable to predation or environmental factors ; in all other seasons the queen tends to be in the deepest of chambers (Tschinkel, 1999). Furthermore, many P. badius colonies move nests during the spring (Carlson and Gentry, 1973 ;Harrison and Gentry, 1981), the only occasion when the queen is outside of the nest other than during her own nuptial flight.…”

Potential and realized reproduction by different worker castes in queen-less and queen-right colonies of Pogonomyrmex badius

Workers of the Florida harvester ant (Pogonomyrmex badius), the only North American Pogonomyrmex with a polymorphic worker caste, produce males when colonies are orphaned. In this study, we assessed the reproductive potential of workers of each caste group, minors and majors, in the presence and absence of the queen, and tested whether males produced in natural queen-right colonies are derived from workers. Worker size was positively correlated with ovariole number such that major workers had approximately double the number of ovarioles as minor workers. The number of vitellogenic oocytes, a measure of reproductive potential, was greater in major compared to minor workers and increased in both worker castes when queens were removed. Major workers have greater reproductive potential than minors although they represent a minority within the colony (~5 % of workers are majors). Worker produced eggs were visible in colonies 28 -35 days after queen removal. This time lag, from queen removal to egg production, is similar to other ants and bees. Though workers are capable of producing viable eggs, we found no evidence that they do so in queen-right colonies, suggesting that worker reproduction is controlled via some social mechanism (self restraint, policing, or inhibition). This result supports predictions of kin selection theory -that due to multiple mating by the queen workers are more related to queen-produced males than most worker-produced males and should thus favor reproduction by the queen and inhibit reproduction by other workers.
