Yet obligate monogyny in Vermont contrasts with facultative polygyny in New York; seasonal polydomy structured colonies strongly in Vermont but only weakly in New York; there was evidence of microgeographic genetic structure and possibly inbreeding in New York but not in Vermont; and there were persistent strong differences in the reproductive biology of the two populations as well (Banschbach and Herbers 1996).
Our data add to the emerging picture of Myrmica species by presenting a new syndrome of obligate monogyny versus facultative polygyny in different populations.
Only one species has thus far been described for which polydomy is accompanied by strict monogyny. Snyder and Herbers (1991), studying a population of Myrmica punctiventris, in Vermont, showed that colonies there consist of up to 10 nest subunits, among which there is one singly-mated queen.
tuberculatum colonies both in Veracruz and in Chiapas, whatever the social structure (monogyny or facultative polygyny) of their populations.
The ideal conditions assumed by Hamilton (1964) - monogyny, monoandry, and no worker reproduction (hereafter referred to as Hamiltonian conditions) - held.
We included these species in our analysis recognizing that "monogyny" and "polygyny" here refers to the number of queens per colony.
When queens mate only once (monandry) and colonies have only one queen (monogyny), then the average relatedness of the brood, consisting of either brothers and sisters (1) or sons and daughters (2), is equal and r cancels out.
