This summary delves into various biomes, focusing on their unique characteristics like the chaparral, tropical forests, and tundras. You will learn about the ecological significance of vegetation and how it influences food webs and ecological niches. The interplay between climate and physical factors, alongside plant adaptations, shapes the distinct forms of trees and other flora. Additionally, the impact of animal populations on vegetation is examined, highlighting the synthesis of population genetics and ecology that informs our understanding of these vital ecosystems.

Scrub • Called “chaparral” in the text • Dry summers • Different specieson differentcontinents
Tropical forest • Rain forest and dry forest • Daily range oftemperaturegreater thanyearly
Coniferous forest • High latitudes in the northand south • Tree shapes • Evergreens and evergreens
Temperate broadleaf forest • Why deciduous? • Tree shape
Tundra • Arctic/AntarcticTundra • Alpine Tundra • What about the tropics?
So what about biomes? • Determined by climate, physical factors • Plant adaptations control the shape of the vegetation • The vegetation is the foundation of food webs and ecological niches, and thus controls the animals…but…. • Animals can cause changes in vegetation
