Mutations in the Aspergillus nidulans fluG gene disrupt the programmed induction of asexual sporulation and result in formation of fluffy colonies that are characterized by undifferentiated cotton-like masses of vegetative cells. We show that the fluG mutant phenotype is suppressed when fluG mutant colonies are grown next to wild-type colonies even if the two strains are separated by dialysis m...

Sentinels are a conspicuous feature of some cooperative societies and are often assumed to provide benefits in terms of increased predator detection. Similar to other cooperative behaviours, variation in investment in sentinel behaviour should reflect variation in the benefits of such behaviour. However, evidence for this is inconclusive: to date experiments have manipulated the cost of sentine...
