The growing public awareness of the increasing number of large wildfires across forested landscapes, coupled with needs of resource base management has accelerated research into forest reference conditions and the historical role of fire in coniferous ecosystems.
Brown-rot fungi are important recyclers in coniferous forest ecosystems and cause a highly destructive type of wood decay.
Therefore, this form of interaction between the dominant vegetation and the nitrogen cycle held true despite a threshold in climate being passed and a shift from coniferous-dominated ecosystem to a deciduous-dominated one.
We used snow track surveys as a measure of habitat use and fecal nitrogen as an index of dietary quality to compare the relative value to mule deer of open deciduous canopies to closed coniferous canopies in a wet ecosystem with deep snow and few fires.
This represented an ecosystem shift from coniferous-dominated to deciduous-dominated forest following rapid climate warming at 11,700 cal.
A validation scheme was implemented over a wide range of forested landscapes, looking at both deciduous and coniferous sites, from tropical to boreal ecosystems.
Similar ecosystem failure is occurring in the coniferous forests of North America as milder winters and longer summers tip the balance in favor of native bark beetles.
Several authors have suggested that leaf area index (LAI) is the principal scaling variable for both gross photosynthesis and ecosystem respiration of northern deciduous and coniferous forests e.g. [76].

"But it is by definition an underestimate of sensitivity because biological interactions (like bark beetles in coniferous forests and bleaching events in corals) show major ecosystem impacts can occur on top of and as part of vegetation or ecosystem impacts," Lovejoy told the newspaper.
