Natural climate solutions (NCS) in the Arctic hold the potential to be implemented at a scale able to substantially affect the global climate. The strong feedbacks between carbon-rich permafrost, climate and herbivory suggest an NCS consisting of reverting the current wet/moist moss and shrub-dominated tundra and the sparse forest–tundra ecotone to grassland through a guild of large herbivores. Grassland-dominated systems might delay permafrost thaw and reduce carbon emissions—especially in…

What evidence exists on the impacts of large herbivores on climate change? A systematic map protocol
Background In recent years there has been an increased focus on the role of large herbivores in ecosystem restoration and climate change mitigation. There are multiple processes by which large
Climate change and ecosystems: threats, opportunities and solutions
TLDR
Novel perspectives on how ecosystems respond to climate change, how ecosystem resilience can be enhanced and how ecosystems can assist in addressing the challenge of a changing climate are explored.
Mitigation of Arctic permafrost carbon loss through stratospheric aerosol geoengineering
TLDR
It is shown that stratospheric sulfate aerosol injection geoengineering can help to avoid about 14 gigatons of carbon release and US$8.4 trillion in economic losses by 2070 compared to RCP4.5 emissions.
Large Herbivores Affecting Permafrost – Impacts of Grazing on Permafrost Soil Carbon Storage in Northeastern Siberia
Abstract. The risk of carbon emissions from permafrost ground is linked to ground temperature and thus in particular to thermal insulation by vegetation and organic soil layers in summer and snow

How does spatial heterogeneity affect inter‐ and intraspecific growth patterns in tundra shrubs?
Arctic and alpine ecosystems are strongly affected by rapidly changing environmental conditions, resulting in profound vegetation shifts, which are highly heterogeneous and hard to predict, yet have
Existing evidence on the outcomes of wildlife translocations in protected areas: a systematic map
Background Ecosystem degradation, mainly through overexploitation and destruction of natural habitats, is a well-known threat to the viability and persistence of many species’ populations worldwide.

Trophic rewilding as a climate change mitigation strategy?
TLDR
This work provides a novel synthesis of the various ways that megafauna interact with the major drivers of anthropogenic climate change, including greenhouse gas storage and emission, aerosols and albedo, and explores the role of rewilding as a mitigation tool at two scales.
High resilience in the Yamal-Nenets social–ecological system, West Siberian Arctic, Russia
TLDR
It is found that despite anthropogenic fragmentation and transformation of a large proportion of the environment, recent socioeconomic upheaval, and pronounced climate warming, the Yamal-Nenets SES is highly resilient according to a few key measures.

TLDR
It is concluded that there is a potential to reintroduce large herbivores in many arctic locations, and that doing so would potentially reduce some of the unwanted effects of a warmer climate.

Steppe-Tundra Transition: A Herbivore-Driven Biome Shift at the End of the Pleistocene
TLDR
Results indicate that mammalian grazers have a sufficiently large effect on vegetation and soil moisture that their extinction could have contributed substantially to the shift from predominance of steppe to tundra at the Pleistocene-Holocene boundary.
Herbivores inhibit climate‐driven shrub expansion on the tundra
Recent Pan‐Arctic shrub expansion has been interpreted as a response to a warmer climate. However, herbivores can also influence the abundance of shrubs in arctic ecosystems. We addressed these
Pleistocene Rewilding: An Optimistic Agenda for Twenty‐First Century Conservation
TLDR
Pleistocene rewilding would deliberately promote large, long‐lived species over pest and weed assemblages, facilitate the persistence and ecological effectiveness of megafauna on a global scale, and broaden the underlying premise of conservation from managing extinction to encompass restoring ecological and evolutionary processes.

Reviews and syntheses: Changing ecosystem influences on soil thermal regimes in northern high-latitude permafrost regions
Abstract. Soils in Arctic and boreal ecosystems store twice as much carbon as the atmosphere, a portion of which may be released as high-latitude soils warm. Some of the uncertainty in the timing and
High herbivore density associated with vegetation diversity in interglacial ecosystems
TLDR
Signs are found of high abundances of large herbivores and a mosaic of closed forest and wood–pasture vegetation in the last interglacial period and primarily closed forests with lower herbivore abundance in the early Holocene, which support an important role for large Herbivores in driving vegetation dynamics and in current efforts to promote landscape diversity through rewilding.
