An El Niño is a warming of the Pacific Ocean between South America and Papua New Guinea (just north of Australia, an island in the Southwest Pacific). This occurs when the trade winds in that region weaken, which causes the west coast of South America to experience warmer waters. This effect also allows the thermocline to move deeper.

Age doesn't determine survival or mortality. This curve shows that death is a constant regardless of age. Type 3 curve shows a species that has an early loss population and few live to old age. This is what the R-selected graph looks like, since many offspring are born yet few survive due to neglect or unindividualized parental attention.Some of the key factors that can shape the devolutionary process include: Political context: The political context, including the balance of power between different levels of government and the broader political landscape, can have a significant impact on the devolutionary process.
