We review and present a synthesis of the existing research dealing with changing Arctic tundra ecosystems, in relation to caribou and reindeer winter ranges. Whereas pan-Arctic studies have documented the effects on tundra vegetation from simulated climate change, we draw upon recent long-term regional studies in Alaska that have documented the actual, on-the-ground effects. Our review reveals signs of marked change in Arctic tundra ecosystems. Factors known to be affecting these changes… 

Simulating the effects of climate change on fire regimes in Arctic biomes: implications for caribou and moose habitat

Wildfire is the primary ecological driver of succession in the boreal forest and may become increasingly important within tundra ecosystems as the Arctic warms. Migratory barren-ground caribou

Observed and predicted effects of climate change on Arctic caribou and reindeer

The ability of many species to adapt to the shifting environmental conditions associated with climate change will be a key determinant of their persistence in the coming decades. This is a challenge

Chapter 9. Caribou herd dynamics: impacts of climate change on traditional and sport harvesting

Caribou ( Rangifer tarandus ) are a key species in Arctic ecosystems including northern Québec and Labrador. They play a central role in the ecology of predators and the structure of Arctic plant

Winter Habitat Selection by Caribou in Relation to Lichen Abundance, Wildfires, Grazing, and Landscape Characteristics in Northwest Alaska

Abstract: Lichens are an important winter forage for large, migratory herds of caribou (Rangifer tarandus granti) that can influence population dynamics through effects on body condition and in turn

What are the impacts of reindeer/caribou (Rangifer tarandus L.) on arctic and alpine vegetation? A systematic review protocol

BackgroundReindeer and caribou (both belonging to the species Rangifer tarandus L.) are among the most important large herbivores in Eurasia’s and North America’s arctic, alpine and boreal zones. In

Twenty-Five Year Record of Changes in Plant Cover on Tundra of Northeastern Alaska

Abstract Northern Alaska has warmed over recent decades and satellite data indicate that vegetation productivity has increased. To document vegetation changes in the Arctic National Wildlife Refuge,

Plant–Environment Interactions in the Low Arctic Torngat Mountains of Labrador

The eastern Canadian Subarctic and Arctic are experiencing significant environmental change with widespread implications for the people, plants, and animals living there. In this study, we integrate

Alpine lichen-dominated heaths: ecology, effects of reindeer grazing, and climate change. A review

Lichens are important forage for reindeer during winter, making evaluation of lichen biomass important for reindeer population management. Lichen heaths have a scattered distribution at high

The Impact of Deciduous Shrub Dominance on Phenology, Carbon Flux, and Arthropod Biomass in the Alaskan Arctic Tundra

The Impact of Deciduous Shrub Dominance on Phenology, Carbon Flux, and Arthropod Biomass in the Alaskan Arctic Tundra Shannan Kathlyn Sweet Arctic air temperatures have increased at two to three

Shrub expansion in tundra ecosystems: dynamics, impacts and research priorities

Recent research using repeat photography, long-term ecological monitoring and dendrochronology has documented shrub expansion in arctic, high-latitude and alpine tundra ecosystems. Here, we (1)



Fire, Lichens, and Caribou

Continental populations of caribou (Rangifer tarandus) usually winter in the northern taiga. Fire is a natural feature of the ecology of the taiga but its effect on the winter range of caribou has

Reindeer (Rangifer tarandus) and climate change: Importance of winter forage

Winter foraging conditions for reindeer and caribou living in arctic, sub-arctic and alpine tundra areas are reviewed, and potential benefits from increased plant productivity due to global warming will be counteracted by shifts in the distribution of preferred lichen forage, reduction of the areas of suitable winter ranges, and generally reduced forage accessibility in winter.

Wildfires in relation to the habitat of barren-ground caribou in the taiga of northern Canada.

OF various factors which might limit barrenground caribou (Rangifer tarandus groenlandicus) populations, destruction of range by fire is one. Fire, caused by lightning or man, generally affects only

Global change and arctic ecosystems: is lichen decline a function of increases in vascular plant biomass?

1 Macrolichens are important for the functioning and biodiversity of cold northern ecosystems and their reindeer‐based cultures and economies. 2 We hypothesized that, in climatically milder parts of

Lichen abundance in the peatlands of northern Alberta: Implications for boreal caribou

ABSTRACT In boreal forests, wildfire is a dominant ecological process that, among other things, affects the distribution and abundance of terrestrial lichens. Woodland caribou (Rangifer tarandus

Lichens of Anaktuvuk Pass, Alaska, with Emphasis on the Impact of Caribou Grazing'

Anaktuvuk Pass in the central Brooks Range of northern Alaska provides a major migration route for the western arctic caribou herd and an analysis by species biomass composition revealed a lichen composition of 31 species, with Cladonia stellaris being the most common and present in almost equal abundance on both exposures.

Fire - caribou - winter range relationships in northern Canada

We needed data on temporal changes in caribou forages after fire and relative use of age-classes of forests by caribou to help devise a fire suppression priority strategy for caribou winter range in

Diets of Overwintering Caribou, Rangifer tarandus , Track Decadal Changes in Arctic Tundra Vegetation

We compared winter diets of Western Arctic Herd Caribou ( Rangifer tarandus ) from 1995/1996 and 2005 using microhistological fecal analysis on samples collected at paired permanent vegetation

Slow Recovery of Lichen on Burned Caribou Winter Range in Alaska Tundra: Potential Influences of Climate Warming and Other Disturbance Factors

ABSTRACT Lichen regeneration timelines are needed to establish sound fire management guidelines for caribou (Rangifer tarandus) winter range. Paired burned and unburned permanent vegetative cover

Response of Overwintering Caribou to Burned Habitat in Northwest Alaska

Caribou ( Rangifer tarandus granti ) use lichens, when available, as primary forage on their winter range. In boreal forest habitats, wildland fires effectively destroy lichens, and overwintering
