Predators can affect prey both directly through consumption and indirectly through non-consumptive effects such as predation risk. The latter has been less studied than consumptive effects in predator-prey interactions, although many studies have shown that non-consumptive effects could significantly affect various life history traits of the prey (Clinchy et al. 2013; Gurr et al. 2017; Hawlena & Schmitz 2010; Hermann & Thaler 2014; McCauley et al. 2011; Peckarsky et al. 2002; Skelhorn et al. 2011; Stoks 2001; Zanette et al. 2011), such as development, reproduction and lifespan in mite prey-predator systems (Choh & Takabayashi 2010; Freinschlag & Schausberger 2016; Grostal & Dicke 1999; Li & Zhang 2019; Ristyadi et al. 2022; Škaloudová et al. 2007; Wei & Zhang 2019, 2022). Most published studies examined the short-term effects of predation risk on prey immature development, reproduction and behaviour (e.g. Abrams & Rowe 1996; Choh et al. 2010; Majchrzak et al. 2022; Oku et al. 2003; Oliveira & Moraes 2021; Rocha et al. 2020; Saavedra et al. 2022; Warkentin 1995). In this study, we examined the effects of predation risk on short-term as well as long-term traits such as fecundity and lifespan. In addition, we also compared the effects of exposure to predation risks for long versus short duration.
