Pyrodendroecology in fire-adapted Pinus species: Linking evolutionary ecology and ecosystem management
Presented by Dr. Peter BROWN on 15 May 2013 from 08:20 to 08:40
Type: Oral Presentation
Track: Science and decision making
Pinus species from around the world exhibit various adaptations to fire as an evolutionary force. Adaptations such as cone serotiny or thick bark are widespread in Pinus, such that Mirov in his classic volume The Genus Pinus (1967) devoted more attention to fire than on any other physiological or ecological factor affecting various species of the genus. In this talk, I focus on how dendroecological analyses of fire scars and other components of fire regimes (pyrodendroecology) can inform both the evolutionary ecology and current and future management of Pinus species and Pinus-dominated ecosystems. I first examine commonalities in fire adaptations in Pinus species from North America, Asia, and the tropics. I then discuss how insights into the adaptive capabilities of these species can contribute to ecosystem restoration efforts that are intended to increase resilient to future disturbances such as uncharacteristic wildfires, widespread insect outbreaks, and climate change.
