Persistence of pyrophilous insects in fire-driven boreal forests: population dynamics in burned and unburned habitats

Several boreal insect species respond to smoke and heat generated by forest fires and use recent burns to reproduce in high numbers. Some of these species are rare or uncommon in undisturbed forests, and the contribution of recently burned habitats to their population dynamics…

Could increased boreal forest ecosystem productivity offset carbon losses from increased disturbances?

To understand how boreal forest carbon (C) dynamics might respond to anticipated climatic changes, we must consider two important processes. First, projected climatic changes are expected to increase the frequency of fire and other natural disturbances that would change the…
