Temperature is a primary driver of the distribution of biodiversity as well as of ecosystem boundaries. Declining temperature with increasing elevation in montane systems has long been recognized as a major factor shaping plant community biodiversity, metabolic processes, and ecosystem dynamics. Elevational gradients, as thermoclines, also enable prediction of long-term ecological responses to climate warming. One of the most striking manifestations of increasing elevation is the abrupt… 
The functional decoupling of processes in alpine ecosystems under climate change.
Background insect herbivory increases with local elevation but makes minor contribution to element cycling along natural gradients in the Subarctic
Despite the minor contribution to overall elemental cycling in subarctic birch forests, the higher quality and earlier timing of the input of herbivore deposits to soils compared to senesced litter may make this contribution disproportionally important for various ecosystem functions.
Coordinated responses of soil communities to elevation in three subarctic vegetation types
Global warming has begun to have a major impact on the species composition and functioning of plant and soil communities. However, long-term community and ecosystem responses to increased temperature
Spatial heterogeneity of tree diversity response to climate warming in montane forests
Tree species richness increased significantly under climate warming in Minshan (MS) and Xiaoxiangling (XXL) with higher warming rate than Qionglai (QLS) and Liangshan (LS), and the trees species diversity in MS and XXL were more sensitive to climatic warming.
Topography modulates near-ground microclimate in the Mediterranean Fagus sylvatica treeline
It is posited that forest microclimatic buffering is sensitive to local topographic conditions and canopy cover, and using meteorological stations equipped with data-loggers this effect is measured during 1 year across a climate gradient in a Mediterranean beech treeline growing in contrasting aspects in southern Italy.
Soil microbial biomass increases along elevational gradients in the tropics and subtropics but not elsewhere
AIM: Our aim is to use elevational gradients to quantify the relationship between temperature and ecosystem functioning. Ecosystem functions such as decomposition, nutrient cycling and carbon storage
Impact of climate change on alpine vegetation of mountain summits in Norway
Climate change is affecting the composition and functioning of ecosystems across the globe. Mountain ecosystems are particularly sensitive to climate warming since their biota is generally limited by
Lags in the response of mountain plant communities to climate change
A mechanistic community model is developed to illustrate how species turnover in future communities might lag behind simple expectations based on species' range shifts with unlimited dispersal, and support the view that accounting for disequilibrium range dynamics will be essential for realistic forecasts of patterns of biodiversity under climate change.
Climatic warming shifts the soil nematode community in a desert steppe
Climatic warming is known to impact terrestrial ecosystem structure and functioning. The response of belowground fauna such as soil nematodes to climatic warming has received little attention, yet


Consequences of Treeline Shifts for the Diversity and Function of High Altitude Ecosystems
Abstract Treeline expansion is reported as a widespread response to rising temperatures, yet few studies have considered the impact of treeline advance on the diversity and function of high altitude
Ecosystem feedbacks and cascade processes: understanding their role in the responses of Arctic and alpine ecosystems to environmental change
Global environmental change, related to climate change and the deposition of airborne N‐containing contaminants, has already resulted in shifts in plant community composition among plant functional
Continent-wide response of mountain vegetation to climate change
Climate impact studies have indicated ecological fingerprints of recent global warming across a wide range of habitats1, 2. Although these studies have shown responses from various local case
Community and ecosystem responses to elevational gradients: processes, mechanisms and insights for global change
Community structure and ecosystem processes often vary along elevational gradients. Their responses to elevation are commonly driven by changes in temperature, and many community- and ecosystem-level
Treeline advance - driving processes and adverse factors
The general trend of climatically-driven treeline advance is modified by regional, local and temporal variations. Treelines will not advance in a closed front parallel to the shift of any isotherm to
Global patterns of mobile carbon stores in trees at the high‐elevation tree line
A global synthesis of previously published and new data on tree carbon supply status at high-elevation tree lines contributes to a mechanistic understanding of tree line formation based on biological principles across climatic zones and tree genera.
Nitrogen cycling at treeline: Latitudinal and elevational patterns across a boreal landscape
ABSTRACT We studied spatial and temporal patterns of nitrogen pools and fluxes in soils at treeline and forested sites within three mountain ranges across a 785-km transect in Alaska during
Stoichiometric homeostasis predicts plant species dominance, temporal stability, and responses to global change.
H(N) may be predictive of plant species success and stability, and how plant species and ecosystems will respond to global-change-driven alterations in resource availability, in experiments simulating a range of forecast hydrologic changes.
The three easily measurable traits tested, specific leaf area, leaf dry matter content, and nitrogen concentration, provide a simple means to scale up from organ to ecosystem functioning in complex plant communities and be used to assess the impacts of community changes on ecosystem properties induced, in particular, by global change drivers.

Results support the hypotheses that leaf N and P increase from the tropics to the cooler and drier midlatitudes because of temperature-related plant physiological stoichiometry and biogeographical gradients in soil substrate age and the N/P ratio increases with mean temperature and toward the equator.
