Why is parental care important to population growth?
Parental care is expected to evolve when the fitness benefits of care outweigh the costs. Benefits of parental care in nature are diverse and can be associated with increased offspring size, increased offspring survival, increased offspring mating success, and/or altered offspring development [7, 12, 13].
Which one is a correct definition of parental care?
Parental care can be defined as any non-genetic contribution by a parent that increases the fitness of offspring, and can occur before or after laying or birth (Stahlschmidt and DeNardo, 2011).
How does parental care impact reproductive success?
Care can be beneficial if parents (1) increase offspring survival during the stage in which parents and offspring are associated, (2) improve offspring quality in a way that leads to increased offspring survival and/or reproduction in the future when parents are no longer associated with offspring, and/or (3) directly …

What is parental care in zoology?

What is the relationship between parental care and survival of offspring?
Parental care is beneficial to parents if it increases offspring survival, growth and/or quality (i.e., offspring performance), and ultimately offspring lifetime reproductive success (Clutton-Brock 1991; Rauter and Moore 2002; Alonso-Alvarez and Velando 2012; Klug et al. 2012; Royle et al.
What are the benefits of parental care?
The main benefit of parental care is offspring survival, although care can also influence an offspring’s condition and future reproductive success. The simplest form of parental care is guarding or protection of eggs in egg-laying, or oviparous, species.
What is parental care Byjus?
Any investment made or any effort taken by parents to take care of the young ones in order to increase the chance of survival of the offspring and hence increase the reproductive rate of success is called parental care.
