Ichthyoplankton assemblage structure of springs in the Yangtze Estuary revealed by biological and environmental visions.

abstract：Background:Much of the shape variation found in animals is based on allometry and heterochrony. Horses represent an excellent model to investigate patterns of size-shape variation among breeds that were intentionally bred for extreme small and large sizes. Methods:We tested whether ponies (wither height < 148 cm) have...
