  • Ready for mating at the right time: How pheromones signal mating cues in tilapia
    Fish rely on pheromones to trigger social responses and to coordinate reproductive behavior in males and females. Scientists have now identified such a signal molecule in the urine of male Mozambique tilapia: this pheromone boosts hormone production and accelerates oocyte maturation in reproductive females.
  • How the zebrafish gets its stripes: Uncovering how beautiful color patterns can develop in animals
    The zebrafish, a small fresh water fish, owes its name to a striking pattern of blue stripes alternating with golden stripes. Three major pigment cell types, black cells, reflective silvery cells, and yellow cells emerge during growth in the skin of the tiny juvenile fish and arrange as a multi-layered mosaic to compose the characteristic color pattern. While it was known that all three cell types have to interact to form proper stripes, the embryonic origin of the pigment cells that develop the stripes of the adult fish has remained a mystery up to now. Scientists have now discovered how these cells arise and behave to form the 'zebra' pattern.
