Ecography, EarlyView.Conservation has shifted towards a climate change adaptation approach in which expected species range shifts are increasingly considered to mitigate effects of climate change and habitat fragmentation on biodiversity. As part of this, ecological connectivity needs to be ensured to support gene flow and viable populations in the face of changing ...

Frontiers in Environmental Science, 2022 Soil carbon (C) in permafrost peatlands is vulnerable to decomposition with thaw under a warming climate. The amount and form of C loss likely depends on the site hydrology following permafrost thaw, but antecedent conditions during peat accumulation are

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra
Ecography, EarlyView.Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.

Influence of topography and moisture and nutrient availability on green alder function on the low arctic tundra, NT [PDF]
, 2017 The Arctic has warmed by at least 3°C over the past 50 years and this rapid warming is expected to continue. Climate warming is driving the proliferation of shrubs across the tundra biome with implications for energy balance, climate, hydrology, nutrient

Influence of allochtonous nutrients delivered by colonial seabirds on soil collembolan communities on Spitsbergen [PDF]
, 2012 Despite a widespread recognition of the role of seabird colonies in the fertilization of nutrient-poor polar terrestrial ecosystems, qualitative and quantitative data documenting any consequential influence on soil invertebrate communities are still ...

Ecography, EarlyView.Despite extensive research, stabilizing mechanisms in ecosystems remain uncertain. Taylor's power law (TPL) is a pervasive ecological pattern that describes how variance scales with mean abundance (σ2 = aμᵇ). While TPL has been widely studied within populations, its role across species within communities and its implications for stability remain ...

Patterned-ground facilitates shrub expansion in Low Arctic tundra
Environmental Research Letters, 2013 Recent expansion of tall shrubs in Low Arctic tundra is widely seen as a response to climate warming, but shrubification is not occurring as a simple function of regional climate trends.

Enabling pastoralist management of rangelands to achieve Land Degradation Neutrality
Frontiers in Ecology and the Environment, EarlyView.Rangelands cover 54% of the global terrestrial area and are threatened by land conversion and degradation, which erodes their global value and weakens the livelihoods of pastoralists who manage them. Sustainable Development Goal Target 15.3 on Land Degradation Neutrality (LDN) provides a framework for sustainable rangelands management, but countries ...

Soil nutrient content dominates short-term vegetation changes in alpine tundra of Changbai Mountains
Frontiers in MicrobiologyAlpine tundra, covering 3% of the Earth’s land surface, harbors approximately 4% of higher plant species. Changes in this vegetation significantly impact biodiversity and ecosystem services.
