متن کاملDo Maternal Food Deprivation and Offspring Predator Cues Interactively Affect Maternal Effort in Fish?
Influences from the parental environment can be transmitted to offspring via parental effects and may profoundly affect the phenotype expressed in subsequent generations, for example, germination season in plants (e.g. Galloway 2001), offspring size (e.g. Naguib & Gil 2005; Taborsky 2006), natal dispersal (e.g. Tschirren et al. 2007) and egg quality (Blount et al. 2002) in several bird and fish...
