Reproductive strategies
Definition: reproductive strategies is when animals take effort to take care of the offspring before it is born, or strategies to actually reproduce. Different strategies hence will come with different costs and benefits.
Reproductive effort is the amount of energy allocated to reproduction. The things that are required to be done after reproduction is parental care.
At one extreme, most intvertebrates expand their total reproductive effort in producing eggs and sperm with no parental care after.
At the other extreme, mammals invest heavily in a small number of offsprings and focus hugely on looking after the offsprings once they are born.
There is also the in between, such as brood parasitism, which is moderate number of offspring and some parental care atter they are reproduced.
Little or no parent care
Many eggs or young produced, meaning there is a higher mortaility rate (death). No parental care means there is a low risk for the parents.
-
Hence more reproductive effort is put into actually producing the offspring but not looking after them (parental care)
E.g. Most fish, amphibians, reptiles and invertebrates.
