Dispersal and fire limit Arctic shrub expansion [PDF]
Nature Communications, 2022 Shrub encroachment trends are widespread yet complex. Here the authors demonstrate that not considering dispersal and fire leads to overestimating shrub expansion in Arctic tundra and therefore its role as carbon sink.

Late Pleistocene shrub expansion preceded megafauna turnover and extinctions in eastern Beringia. [PDF]
Proc Natl Acad Sci U S A, 2021 Significance Megafauna strongly influence vegetation structure, and population declines can alter ecosystem functioning. Overhunting of grazing megafauna is argued to have driven the collapse of widespread, northern steppe-tundra and its replacement by ...

Patterns of shrub expansion in Alaskan arctic river corridors suggest phase transition. [PDF]
Ecol Evol, 2015 Recent increases in deciduous shrub cover are a primary focus of terrestrial Arctic research. This study examined the historic spatial patterns of shrub expansion on the North Slope of Alaska to determine the potential for a phase transition from tundra ...

Shrub expansion raises both aboveground and underground multifunctionality on a subtropical plateau grassland: coupling multitrophic community assembly to multifunctionality and functional trade-off [PDF]
Frontiers in Microbiology, 2023 IntroductionShrubs have expanded into grasslands globally. However, the relative importance of aboveground and underground diversity and the relative importance of underground community assembly and diversity in shaping multifunctionality and functional ...

Nitrogen fixing shrubs advance the pace of tall-shrub expansion in low-Arctic tundra
Communications Earth & Environment, 2023 Tall deciduous shrubs are critically important to carbon and nutrient cycling in high-latitude ecosystems. As Arctic regions warm, shrubs expand heterogeneously across their ranges, including within unburned terrain experiencing isometric gradients of ...

Shrub expansion modulates belowground impacts of changing snow conditions in alpine grasslands [PDF]
Ecology Letters, 2021 Climate change is disproportionately impacting mountain ecosystems, leading to large reductions in winter snow cover, earlier spring snowmelt and widespread shrub expansion into alpine grasslands. Yet, the combined effects of shrub expansion and changing

Shrub expansion in tundra ecosystems: dynamics, impacts and research priorities [PDF]
Environmental Research Letters, 2011 Part of Focus on Dynamics of Arctic and Sub-Arctic Vegetation 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)

Shrub expansion in maritime forest responding to sea level rise
Frontiers in Forests and Global Change, 2023 Expansion of shrubs has been observed in a number of biomes and in response to diverse global change drivers. Noting shrub expansion in coastal forests affected by sea level rise, we began to monitor shrub populations in a transgressing loblolly pine ...

Tree and shrub expansion at treeline drive contrasting responses in a subarctic passerine community [PDF]
Journal of Animal Ecology, 2023 Inferences about the mechanisms of distributional change are often made from simple assessments of variation in the geographical positions of populations.
