Histological characteristics of gills and dorsal skin in ambystoma leorae and ambystoma rivulare: morphological changes for living at high altitude

Int. j. morphol; 35 (4), 2017
SUMMARY: Vertebrates exhibit structural changes in their cardiovascular and gas exchange systems in response to hypoxic conditions in high altitude environments. In highland neotenic mole salamanders, as other amphibians, the majority of gases exchange is carried out for skin and gills. But, in high alti...
