The variances of species abundances from 141 upland stands are partitioned into hab- itat and fire frequency. Principal components analysis is then performed on each of these partitions. The habitat ordination has a topographic-canopy coverage gradient and a nutrient gradient. The fire frequency ordination has one gradient which orders species according to their temporal response after fire, from shorter lived, faster growing, competitively poor species to longer lived, slower growing… 
Habitat preference, growth form, vegetative dispersal and population size of lichens along a wildfire severity gradient
TLDR
It is suggested that habitat association and its mechanisms, along with population size, are presumably important predictors of species-specific response to disturbance, such as fire, for lichens in the boreal forest.
Fire and lichen dynamics in the Taiga Shield of the Northwest Territories and implications for barren‐ground caribou winter forage
QUESTIONS: Fire is the main disturbance agent in boreal forests and has profound effects on vegetation composition and structure, including terrestrial lichens that provide critical winter forage for
UNDERSTORY VASCULAR PLANT SPECIES DIVERSITY IN THE MIXEDWOOD BOREAL FOREST OF WESTERN CANADA
One of the goals of ecosystem management has been to maintain plant species diversity. Emulating the "natural" (pre-European) fire regime is often proposed as a means of accomplishing this goal in
Succession, dominance and diversity in lichen‐rich pine forest vegetation in Finland
TLDR
Succession of forest floor vegetation (cryptogam and understorey vascular plant synusiae) is studied and Stereocaulon-rich stands have diversity values which correspond to Cladina-rich stand with a considerably higher lichen volume, which gives additional evidence for their status as successionally rather mature communities.
Vegetation of forested inland dunes in North Karelia, eastern Finland
The inland sand dunes in North Karelia formed before 3 000 BC. They are now chiefly covered by dry mossor lichen-rich forests of Scots pine (Pinus sylvestris). The releves and species are clustered
Fire and vegetation dynamics in a jack pine and black spruce forest reconstructed using fossil pollen and charcoal
Summary Fire and vegetation dynamics in a boreal Pinus banksiana and Picea mariana forest are reconstructed using a 580 year fossil pollen and charcoal record obtained from 128 contiguous
AN 840‐YEAR RECORD OF FIRE AND VEGETATION IN A BOREAL WHITE SPRUCE FOREST
Boreal forest fire and vegetation history was examined using an 840-yr fossil pollen and charcoal record from a site dominated by Picea glauca in Alberta, Canada. The record was created using
Ecological gradients of boreal forests in South Finland: an ordination test of Cajander's forest site type theory
Ecological gradients in the field layer of southern boreal forests in South Finland were studied in relation to the dominant tree species and the age of forest stands. The data are from a systematic
QUANTIFYING ORGANIZATIONAL CHANGE AFTER FIRE IN LODGEPOLE PINE FOREST UNDERSTOREY
TLDR
The unanticipated behaviour of dry sites is interpreted as reflecting a lower degree of integration of such communities resulting from their particular species composition and susceptibility to biotic disturbance.
THE CREATION OF ALTERNATIVE STABLE STATES IN THE SOUTHERN BOREAL FOREST, QUÉBEC, CANADA
The southernmost spruce-lichen woodlands in the Parc des Grands-Jardins, Quebec, Canada, are situated 500 km south of their usual range in the northern lichen woodland zone. Their co-occurrence

Vegetation succession after fire in sclerophyll woodland communities in south‐eastern Australia
TLDR
The regeneration of the communities studied, as well as the post-fire recovery of numerous different communities reported in the literature, closely resembled an initial floristic composition model.
Derivation of Species Succession Vectors
TLDR
Analysis of data from 879 forest plots in northeastern Wisconsin shows some tree species entering into successional sequences in accordance with existing theory, while other species are apparently as self-perpetuating as the traditional "climax" species of mesic sites.
Studies on lichen-dominated systems. XX. An examination of some aspects of the northern boreal lichen woodlands in Canada
TLDR
Observations suggest that Stereocaulon paschale woodland replaces Cladonia stellaris woodland in a more or less continuous zone from just west of Churchill across to Great Slave Lake, immediately north and south of latitude 60° N.

TLDR
The postfire recovery sequence in spruce woodland growing on drumlins in the Abitau–Dunvegan Lakes area of the Northwest Territories is described and the existence of spruce–Stereocaulon woodland in the area is dependent on cyclic burning.
Studies on lichen-dominated systems. II. The growth pattern of Cladonia alpestris and Cladonia rangiferina
TLDR
The existence of a large-scale mosaic pattern of 'drying rates' is demonstrated by traditional pattern analysis and the relative magnitude of evaporation gradients in open and closed spruce–lichen woodland is presented.

A Phytosociological Ordination of the Conifer Swamps of Wisconsin
TLDR
Bogs have long been a popular study area for botanists, and the literature is voluminous, among the more recent papers from areas near Wisconsin are those of Conway (1949) and Gates (1942).
Fire recurrence in the subarctic and its implications for vegetation composition
TLDR
The Weibull distribution is shown to fit well with empirical data of fire intervals for a population of sites, and the relationship of the distribution's hazard of burning function to vegetation composition and r–K selection is discussed.
Relative abundance of food in winter for Newfoundland caribou
TLDR
Information on the winter feeding behaviour of caribou Rangifer tarandus Bangs in Newfoundland and the relative abundance of food available to them in winter is presented and it is indicated that shrubs were consumed more than the absolute abundance suggested.
