Considering the question above, this pattern of change in vegetation is primarily the result of an "increase in both mean annual temperature and mean annual precipitation."

This is because the annual temperature is defined by the amount of sunlight, while annual precipitation is defined by the amount of rainfall.

Both rainfall and sunlight are the primary agents of vegetation.

Therefore, an increase in both rainfall and sunlight throughout the year will affect the vegetation.

Hence, in this case, the correct answer is option B "An increase in both mean annual temperature and mean annual precipitation"
