Biodiversity conservation: effects of changes in climate and land use.

abstract：:Adult newts regenerate functional limbs after amputation. This process normally depends on the trophic influence of nerves on the regenerating limbs, particularly in the early stages before differentiation of the regeneration blastema, when it stimulates growth by maintaining high rates of macromolecular synthesis.
