Effects of age on sperm quality metrics in endangered Mississippi gopher frogs (Lithobates sevosus) from captive populations used for controlled propagation and reintroduction efforts [0.03%]
年龄对密西西比麝香蛙（Lithobates sevosa）精子质量指标的影响：用于控制繁殖和再引入工作的圈养种群中的作用
Ashley M Watt,Ruth Marcec-Greaves,Kristin M Hinkson et al.
Ashley M Watt et al.
A decline in sperm quality with age is a common prediction of senescence-based hypotheses and empirical studies. While widely studied across taxa, there is little known on the effect of ageing on sperm quality in amphibians, especially in c...
Breeding program in rehabilitated bottlenose dolphins (Tursiops truncatus gephyreus) from the Southwestern Atlantic Ocean [0.03%]
