An evolutionary solution of terrestrial isopods to cope with low atmospheric oxygen levels

摘要: The evolution of current terrestrial life was founded by major waves land invasion coinciding with high atmospheric oxygen content. These were followed periods substantially reduced concentration and accompanied the novel traits. Reproduction development are limiting factors for evolutionary water-land transitions, brood care has probably facilitated invasion. Peracarid crustaceans provide parental their offspring brooding early stages within motherly pouch, marsupium. Terrestrial isopod progeny begin ontogenetic marsupium in water, but conclude air. Our results growth until hatching from evidence effects a potentially adaptive solution. Inclusion air compensates initially constrained water through catch-up growth, it may explain how isopods adapted to short- long-term changes concentration.
