Advanced Search Abstract Most interactions between individuals of social insects occur in colonies.
The correct identification of colonies is therefore crucial for most empirical studies which aim to test evolutionary theories based on properties at the colony level. In many ant populations, the identification of colonics is hampered by polydomy, i.
Only few attempts have been made so far to develop genetical methods for analysing the structure of specific colonics.
Three methods to solve this problem are presented: Our methods quantify the likelihood of nest pairs being con-colonial or non-colonial, and given sufficient genetical resolution, statistical tests can be applied.
The methods proposed here arc applied to a highly polygynous population of the red ant, Myrmica sulcinodis. In this population single colonics are found to inhabit 1—4 nests, and both monodomous and polydomous colonies coexist in dense clusters of nests.
Phylogenetic and Transcriptomic Analysis of Chemosensory Receptors in a Pair of Divergent Ant Species Reveals Sex-Specific Signatures of Odor Coding Vanderbilt University, Nashville, Tennessee, United States of America, 2Departments of Cell and Developmental Biology, Genetics, and Biology, University of Pennsylvania, Philadelphia. Knowledge of genome size, for example, is a useful and necessary prerequisite for the development of many genomic resources, yet it has been reported for only one ant species (Solenopsis invicta), and the two published estimates for this species differ by Mb ( pg). Journal of Experimental Biology ; doi: /jeb Phylogenetic analysis revealed a strong phylogenetic signal in the swimming performance data Many ant species that swim well also have relatively large eyes and presumably have good vision.
This result is discussed with respect to the functional significance of polydomy. Further, the general application of the methods for determination of colony structure is discussed.More than 12, species have been described to date, and it is estimated that perhaps as many still await classification.
Ant Ecology explores key ecological issues and new developments in myrmecology across a range of scales. Thus, the ant chemosensory system must have evolved to be able to perceive these numerous chemicals, many of which differ by species.
Our understanding of the molecular basis and neuronal circuitry of the insect olfactory system has improved greatly during the past decade [ 8, 9 ].

tion of ant species, it is impossible to study their ecol- ogy and biology and to organize an effective system of forest protection in which ants of the genus Formica.
species that probably nested, and an additional 10 species from nearby. This high level of ant diversity, including many rare species, suggests that ant species lists for most parts of the world. Aug 30, · Phylogenetic analysis of these newly annotated genes indicates that there are likely to be vast differences in the importance of particular chemoreceptor families and subfamilies between the four ant species examined, which is likely to reflect the variety of ecological and social demands experienced the members of each species.
