Immune competence and spleen size scale with colony status in the naked mole-rat
Naked mole-rats (NM-R; Heterocephalus glaber) live in multi-generational colonies with a social hierarchy, and show low cancer incidence and long life-spans. Here we asked if an immune component might underlie such extreme physiology.

Data_Sheet_1_Life History and the Transitions to Eusociality in the Hymenoptera.docx
Although indirect selection through relatives (kin selection) can explain the evolution of effectively sterile offspring that act as helpers at the nest (eusociality) in the ants, bees, and stinging wasps (aculeate Hymenoptera), the genetic, ecological ...

What Kills the Hindgut Flagellates of Lower Termites during the Host Molting Cycle?
Subsocial wood feeding cockroaches in the genus Cryptocercus, the sister group of termites, retain their symbiotic gut flagellates during the host molting cycle, but in lower termites, closely related flagellates die prior to host ecdysis.

Discrete but variable structure of animal societies leads to the false perception of a social continuum [PDF]
Animal societies are typically divided into those in which reproduction within a group is monopolized by a single female versus those in which it is shared among multiple females.

Evolution of eusociality in termites [PDF]
A model is presented that demonstrates that asymmetries in relatedness such that individuals are more closely related to siblings than to offspring develop in diploid pedigrees under conditions of inbreeding. Given also certain incestuous conditions, the model predicts that eusocial-type helping behavior can be favored by natural selection. Three cases

Antagonistic pleiotropy and the evolution of extraordinary lifespans in eusocial organisms
Queens of eusocial species live extraordinarily long compared to their workers. So far, it has been argued that these lifespan divergences are readily explained by the classical evolutionary theory of ageing. As workers predominantly perform risky tasks,

The Next Frontier in Understanding the Evolution of Coral Reef Fish Societies
Research on sociality in marine fishes is a vibrant field that is providing new insights into social evolution more generally. Here, we review the past two decades of research, identifying knowledge gaps and new directions.

Brain microRNAs among social and solitary bees [PDF]
Evolutionary transitions to a social lifestyle in insects are associated with lineage-specific changes in gene expression, but the key nodes that drive these regulatory changes are unknown.
