Draft genome of a human gut-derived sp. that ameliorates colitis and colitis-associated sociability deficits in mice.

is a genus of anaerobic, gram-positive bacteria commonly found in mammalian gastrointestinal tracts. Yet, how variations among different strains can impact host health is poorly understood. We present a sp.

Latency for facultative expression of male-typical courtship behaviour by female bluehead wrasses depends on social rank: the 'priming/gating' hypothesis.

Although socially controlled sex transformation in fishes is well established, the underlying mechanisms are not well understood. Particularly enigmatic is behavioural transformation, in which fish can rapidly switch from exhibiting female to male-typical courtship behaviours following removal of 'supermales'. Bluehead wrasses are a model system for investigating environmental control of sex determination, particularly the social control of sex transformation.
