Relationships between summer Thermal variations and cell proliferation in heterothermic vertebrates, as revealed by PCNA expression in the brain of adult Rana bergeri (Günther, 1986) [PDF]
About the issue if the natural encephalic proliferative activities can be infl uenced by the seasonal (thermal and photoperiodic) cyclic fl uctuations in adult earth-dwelling Anamnia and poikilothermal Amniota there is a gap regarding expressly summer ...
