Decrease of lichens in Arctic ecosystems: the role of wildfire, caribou, reindeer, competition and climate in north-western Alaska
K Joly, RR Jandt, DR Klein - Polar Research, 2009 - Taylor & Francis
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 …

Long-term human impact and vegetation changes in a boreal forest reserve: implications for the use of protected areas as ecological references
T Josefsson, G Hörnberg, L Östlund - Ecosystems, 2009 - Springer
Northern boreal forest reserves that display no signs of modern forest exploitation are often
regarded as pristine and are frequently used as ecological reference areas for conservation …

Lichen cover mapping for caribou ranges in interior Alaska and Yukon
Previous research indicates that the effects of climate warming, including shrub expansion
and increasedfire frequency may lead to declining lichen abundance in arctic tundra and …

Winter habitat selection by caribou in relation to lichen abundance, wildfires, grazing, and landscape characteristics in northwest Alaska
K Joly, FS Chapin III, DR Klein - Ecoscience, 2010 - Taylor & Francis
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 …

Non‐parametric methods reveal non‐linear functional trait variation of lichens along environmental and fire age gradients
Questions Popular methods to analyse community–trait–environment relationships constrain
community patterns by trait and environment relationships. What if some traits are strongly …

[HTML][HTML] Predicted impacts of global change on bottom-up trophic interactions in the plant-ungulate-wolf food chain in boreal forests
J Dong, LJ Anderson - Food Webs, 2022 - Elsevier
Global warming has been accelerating as atmospheric CO 2 has risen. The mean annual
temperature in boreal forests has increased by 1.5° C or more, which has profound impacts …

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 …

Lichen traits and species as indicators of vegetation and environment
Lichens in the Arctic play important ecological roles. They also face the threats of increasing
fire and shrub and tree expansion, exacerbated or caused by climate change. These forces …

Fire disturbance promotes biodiversity of plants, lichens and birds in the Siberian subarctic tundra
Fire shapes the world's terrestrial ecosystems and has been influencing biodiversity patterns
for millennia. Anthropogenic drivers alter fire regimes. Wildfires can amplify changes in the …
