A mechanism for cryptic female choice in chinook salmon (2008, methodology): “…was recorded using a high-resolution digital videocam, and sperm longevity (DUR in s) for each milt sample was recorded using a stopwatch, starting at the contact of the milt with the activation solution and ending when all progressive forward motility had ceased (e.g., Leach and Montgomerie 2000).”
Ovarian fluid enhances sperm movement in Arctic charr (2002, methodology): “This pattern is typical of externally fertilizing fishes (Leach & Montgomerie, 2000).”
Effects of ovarian fluid on sperm velocity in Arctic charr (Salvelinus alpinus) (2005, background): “2001), suggesting that sperm from sneaky males might have higher velocity to counter the disadvantage of being ejaculated later or further from the egg (Leach and Montgomerie 2000).”
Sperm swimming speed and energetics vary with sperm competition risk in bluegill (Lepomis macrochirus) (2004, methodology): “Thus, because cuckolders are in a disfavored role with respect to sperm competition, they generally invest more in sperm production than do parentals (e.g., Gage et al. 1995; Leach and Montgomerie 2000 ), in accordance with theory (Parker 1990).”
Multiple Male Reproductive Morphs in the Invasive Round Goby (Apollonia melanostoma) (2009, background): “(2004) reported that sneaker males had longer sperm, in accordance with theoretical predictions, in fact the majority of studies that have examined sperm morphology of males exhibiting alternative reproductive tactics have failed to find differences in sperm length within species (Fitzpatrick et al.”
Sexual colouration and sperm traits in guppies (2007, methodology): “A sub-sample of sperm (20 ml) was used to assess sperm morphometry using techniques similar to those described by Leach & Montgomerie (2000).”
Hormonal manipulations for the enhancement of sperm production in cultured fish and evaluation of sperm quality (2017, background): “, 2010), hierarchical position of dominant versus subordinate fish (Leach and Montgomerie, 2000; Rudolfsen et al., 2008a; Vladić, 2001), presence of dominantfish on subordinate fish (Kustan et al.”
Sperm investment and alternative mating tactics in bluegill sunfish (Lepomis macrochirus) (2003, background): “Leach and Montgomerie (2000) compared sperm from sneakers with those parentals and found that sperm density in stripped ejaculates from sneakers is higher, and although sperm from sneakers appears to swim slower, it is of similar length and longevity.”
