Punctuated equilibrium suggests that evolution happens in rapid bursts followed by long periods of stability, while natural selection is the mechanism by which advantageous traits are passed on to future generations. Punctuated equilibrium emphasizes rapid changes in species, while natural selection is a gradual process that acts on individuals over time.
Punctuated equilibrium is a model of evolution in which species exhibit long periods of stasis, where little change occurs, punctuated by brief periods of rapid change. This theory suggests that most evolutionary change happens over relatively short periods of time during events like speciation.
Both gradualism and punctuated equilibrium are theories of evolution. They both propose that species evolve over time in response to their environment. The main difference is in the pace of change - gradualism suggests that evolution occurs slowly and steadily, while punctuated equilibrium proposes that it occurs in rapid bursts separated by long periods of stasis.
Stasis in the theory of punctuated equilibrium refers to long periods of evolutionary stability without significant change in a species. It occurs between rapid bursts of evolution (punctuation) that result in new species formation. Stasis can occur when a species is well-adapted to its environment and experiences little external pressure to change.
Gradualism suggests that evolution occurs slowly and steadily over time, while punctuated equilibrium proposes that species remain stable for long periods with sudden bursts of change. Punctuated equilibrium suggests that evolutionary change can happen rapidly in localized populations, leading to new species formation. Both theories offer explanations for the pace of evolution, with punctuated equilibrium emphasizing episodes of rapid change interspersed with periods of stasis.

Punctuated Evolution or equilibrium
It is called Punctuated Equilibrium. Some Evolutionary apologists, notably Richard Dawkins, have down played this aspect of Neo-Darwinistic theory.
Punctuated equilibrium.
No difference.
Punctuated equilibrium predicts that a lot of evolutionary change takes place in short periods of time tied to speciation events.

Punctuated equilibrium
This is the idea called punctuated equilibria, by paleontologists Stephen Jay Gould and Niles Eldredge. It explains the patterns seen in the fossil record.
