Abstract
Intraspecific variability in social organization is common, yet the underlying
causes are rarely known. In the fire ant Solenopsis invicta, the existence of
two divergent forms of social organisation is under the control of a single
Mendelian genomic element marked by two variants of an odorant binding protein
(OBP) gene. Here we characterize the genomic region responsible for this
important social polymorphism and show that it is part of a pair of
heteromorphic chromosomes having many of the key properties of sex chromosomes.
The two variants, hereafter referred to as the social B and social b (SB and
Sb) chromosomes, are characterized by a large region of ca. 13 Mb (55% of the
chromosome) where recombination is completely suppressed between SB and Sb.
Recombination appears to occur normally between the SB chromosomes but is
impossible between Sb chromosomes because Sb/Sb individuals are non-viable.
Genomic comparisons revealed limited differentiation between SB and Sb, and the
vast majority of the 616 genes identified in the non-recombining region are
present in the two variants. The lack of recombination over more than half of
the two heteromorphic social chromosomes can be explained by at least one large
inversion of ca. 9 Mb, and this absence of recombination has led to the
accumulation of deleterious mutations including repetitive elements in the
non-recombining region of Sb compared with the homologous region of SB.
Importantly, most of the genes with demonstrated expression differences between
individuals of the two social forms reside in the non-recombining region. These
findings highlight how genomic rearrangements can maintain divergent adaptive
social phenotypes involving many genes acting in concert by locally limiting
recombination.

Upcoming Events
New Technologies for Monitoring Biodiversity Symposium
16 and 17 May 2013
Organisers:
Jonathan Baillie, Zoological Society of London; Kate Jones, University College
London and Zoological Society of London; Margaret Kinnaird, Wildlife
Conservation Society; Tim O'Brien, Wildlife Conservation Society and Marcus
Rowcliffe, Zoological Society of London
Biodiversity monitoring provides the essential information on which
conservation action is based. Consistent, cost-effective implementation of
monitoring is a major challenge, but capacity is developing rapidly through
innovative use of technology, providing exciting opportunities for better and
more affordable information on the state of the world's wildlife. These
technologies are based around the deployment of autonomous sensors to gather
information in ways that human observers cannot: at larger scales, over longer
periods, and in more inaccessible places, and including satellite, aerial,
ground based and underwater applications.
While these technologies present new opportunities, they also throw up new
challenges and questions. How can we design, smaller, stronger, cheaper, more
sensitive and more flexible sensors for biodiversity monitoring? How can we
deploy these sensors most effectively? How can we best process and analyse the
data they produce to provide useful outputs?
This symposium will give an insight into the state of the art in this area,
focusing on satellite and aerial survey techniques, camera trap and related
technologies, acoustic recording and the use of technology to facilitate and
motivate the participation of citizen scientists in monitoring.
