“…Although we saw differences in cortisol concentrations between populations and increased cortisol concentrations when LPP females were exposed to predators in the short term, these results did not transfer into differences in female reproductive output. Our results reflect conclusions of another study in which predator presence did not influence reproductive output in another population of H. formosa (Mukherjee, Heithaus, Trexler, Ray‐Mukherjee, & Vaudo, ). We did see differences in the number and size of offspring and reproductive allocation of females between the two populations (the LPP produced larger and heavier offspring), but neither population responded differently to the treatment.…”

“…energy reserves) with increasing predation risk [80]. With respect to mosquitofish, nonlethal effects of predator exposure have been found to lower their body condition, ultimately leading to lower fertility and fecundity rates [31]. Under this perspective, evidence from this study indicates that a relatively brief exposure to a biologically inspired robotic predator compromised the body condition of mosquitofish.…”

“…When an animal is under stress (risk of predation specifically), the neurological registering of the risk cues causes an increase in stress hormones being released in the body of the animal ( Gross & Canteras, 2012 ). The physiological responses to these stress hormones are energetically costly ( Apfelbach et al, 2005 ) and result in lowered productivity (e.g., Mukherjee et al, 2014 ).…”
