This chapter examines the interplay between shoot structure and canopy function in pine forests in three parts. The first two synthesize research on shoot hydraulics and architecture in relation to light absorption, establishing the foundation for understanding resource delivery within crowns. Using a modeling approach, the last part of the chapter explores the combined effects of crown structure and active-season solar angles on canopy light absorption (as a proxy for potential photosynthetic production) of virtual stands of three pine species with differing shoot characteristics. The simulation results suggest potential limits to the migration of different pine species beyond their current latitudinal ranges and the possible consequences of such migration on species composition of pine ecosystems.

摘要

This chapter examines the interplay between shoot structure and canopy function in pine forests in three parts. The first two synthesize research on shoot hydraulics and architecture in relation to light absorption, establishing the foundation for understanding resource delivery within crowns. Using a modeling approach, the last part of the chapter explores the combined effects of crown structure and active-season solar angles on canopy light absorption (as a proxy for potential photosynthetic production) of virtual stands of three pine species with differing shoot characteristics. The simulation results suggest potential limits to the migration of different pine species beyond their current latitudinal ranges and the possible consequences of such migration on species composition of pine ecosystems.
