Biology of subterranean termites: insights from molecular studies of Reticulitermes and Coptotermes.
This work states that as additional molecular tools and genomic resources become available, and as more subterranean termite researchers incorporate molecular techniques into their approaches, the authors can expect accelerating advances in all aspects of the biology of this group.
Juvenile hormone in adult eusocial Hymenoptera: gonadotropin and behavioral pacemaker.
Results of these studies demonstrate that JH acts as a "behavioral pacemaker," influencing how fast a worker grows up and makes the transition from nest activities to foraging, and hypotheses concerning the evolutionary relationship between the two functions of JH are discussed.
Colony genetic organization and colony fusion in the termite Reticulitermes flavipes as revealed by foraging patterns over time and space
It is demonstrated here that subterranean termite colonies with a similarly complex genetic composition can form under natural conditions via the fusion of whole colonies through repeated sampling from individual colonies over time and space.
Molecular traces of alternative social organization in a termite genome.
The genome and stage-specific transcriptomes of the dampwood termite Zootermopsis nevadensis (Blattodea) are sequence and similarities in the number and expression of genes related to caste determination mechanisms support a hypothesized epigenetic regulation of caste differentiation.
Colony Size as a Buffer Against Seasonality: Bergmann's Rule in Social Insects
It is proposed that shorter growing seasons in the temperate latitudes cull small-colony species through overwintering starvation, which contributes to Bergmann's rule in social insects.

Results indicate that the study populations of R. flavipes have a breeding system characterized by monogamous pairs of outbred reproductives and relatively low levels of inbreeding because most colonies do not live long enough to produce neotenics, and those colonies that do generate neotENics contain an effectively small number of them.
Inclusive fitness theory and eusociality
It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.
The diminutive supercolony: the Argentine ants of the southeastern United States
The results show that the southeastern L. humile population has high genotypic variability and strong intercolony aggression relative to the California population, suggesting that distinctly different colonization patterns for California and the Southeast may be responsible for the striking disparity in the genetic diversity of introduced populations.
Queen Succession Through Asexual Reproduction in Termites
A previously unknown termite breeding system in which both parthenogenesis and sexual reproduction are conditionally used is identified, showing how eusociality can lead to extraordinary reproductive systems and provide important insights into the advantages and disadvantages of sex.
Genetic Structure of Termite Colonies and Populations
Genetic evidence does not support budding as a common mode of reproduction in termites, and the powerful approach to termite colony and population genetics afforded by molecular markers will address a wide range of issues of fundamental importance totermite biology and evolution.
