Stay or go - How topographic complexity influences alpine plant population and community responses to climate change

  
Perspectives in Plant Ecology, Evolution and Systematics (November 2017), https://doi.org/10.1016/j.ppees.2017.09.008

Abstract

In the face of climate change, populations have two survival options − they can remain in situ and tolerate the new climatic conditions (“stay”), or they can move to track their climatic niches (“go”). For sessile and small-stature organisms like alpine plants, staying requires broad climatic tolerances, realized niche shifts due to changing biotic interactions, acclimation through plasticity, or rapid genetic adaptation. Going, in contrast, requires good dispersal and colonization capacities. Neither the magnitude of climate change experienced locally nor the ...

 

Complex responses to global change at alpine treeline

  
Physical Geography, Vol. 22, No. 4. (1 July 2001), pp. 333-342, https://doi.org/10.1080/02723646.2001.10642747

Abstract

A focus of geography is the study of complexity: we include many interacting processes when we study places. Another view of complexity in geography is that complex pattern, in particular spatial pattern, can arise from few or simple interactions, if they are nonlinear. Environmental responses to global change are likely to be nonlinear and thus complex. Shifts in ecotones–the boundaries of vegetation types or biomes–may be indicative of such complex response to global change. One reason for expecting nonlinearity is that ...

 

A climate-based model to predict potential treeline position around the globe

  
Alpine Botany, Vol. 124, No. 1. (2014), pp. 1-12, https://doi.org/10.1007/s00035-014-0124-0

Abstract

In situ temperature measurements revealed that the position of the high-elevation treeline is associated with a minimum seasonal mean air temperature within a temperature-defined minimum season length across latitudes. Here, we build upon this experience and present the results of a global statistical analysis and a predictive model for low temperature treeline positions. We identified 376 natural treelines from satellite images across the globe, and searched for their closest climatic proxies using a climate database. The analysis included a snow and ...

Vegetation-microclimate feedbacks in woodland-grassland ecotones

  
Global Ecology and Biogeography, Vol. 22, No. 4. (April 2013), pp. 364-379, https://doi.org/10.1111/geb.12000

Abstract

[Aim] Climatic conditions exert a strong control on the geographic distribution of many woodland-to-grassland transition zones (or ‘tree lines’). Because woody plants have, in general, a weaker cold tolerance than herbaceous vegetation, their altitudinal or latitudinal limits are strongly controlled by cold sensitivity. While temperature controls on the dynamics of woodland–grassland ecotones are relatively well established, the ability of woody plants to modify their microclimate and to create habitat for seedling establishment and growth may involve a variety of processes that are ...

 

Recent invasion of the mountain birch Betula pubescens ssp. tortuosa above the treeline due to climate change: genetic and ecological study in northern Sweden

  
Journal of Evolutionary Biology, Vol. 20, No. 1. (January 2007), pp. 369-380, https://doi.org/10.1111/j.1420-9101.2006.01190.x

Abstract

Mountain birch, Betula pubescens ssp. tortuosa, forms the treeline in northern Sweden. A recent shift in the range of the species associated with an elevation of the treeline is commonly attributed to climate warming. Using microsatellite markers, we explored the genetic structure of populations along an altitudinal gradient close to the treeline. Low genetic differentiation was found between populations, whereas high genetic diversity was maintained within populations. High level of gene flow compensated for possible losses of genetic diversity at higher ...

 

Interactions between growth, demography and biotic interactions in determining species range limits in a warming world: The case of Pinus sylvestris

  
Forest Ecology and Management, Vol. 282, No. 0. (2012), pp. 10-22, https://doi.org/http://dx.doi.org/10.1016/j.foreco.2012.06.053

Abstract

Changes in climate are affecting the distribution and status of species on a global scale, through alteration of factors including their phenology, growth and ecological interactions. These alterations are often most apparent at species range edges, where changes to conditions previously limiting the species distribution can result in range shifts. In this paper, we review the rapid recent increase in our understanding of the factors limiting the distribution of a species to explore how the interaction of biotic and abiotic factors ...

 

Impacts of Climate Change on the Tree Line

  
Annals of Botany, Vol. 90, No. 4. (01 October 2002), pp. 537-544, https://doi.org/10.1093/aob/mcf222

Abstract

The possible effects of climate change on the advance of the tree line are considered. As temperature, elevated CO2 and nitrogen deposition co‐vary, it is impossible to disentangle their impacts without performing experiments. However, it does seem very unlikely that photosynthesis per se and, by implication, factors that directly influence photosynthesis, such as elevated CO2, will be as important as those factors which influence the capacity of the tree to use the products of photosynthesis, such as temperature. Moreover, temperature limits ...

 

Cascading effects of feedbacks, disease, and climate change on alpine treeline dynamics

  
Environmental Modelling & Software, Vol. 62 (December 2014), pp. 85-96, https://doi.org/10.1016/j.envsoft.2014.08.019

Abstract

[Highlights] [::] Facilitation, particularly from whitebark pine, drives tree island development. [::] Positive and negative feedbacks influence whitebark pine treeline dynamics. [::] Climate amelioration reduces facilitation benefits, causing dispersed tree pattern. [::] Blister rust disease-killed pine impacts all species, despite climate improvement. [::] Treeline responded negatively with disease introduction, even when climate improved. [Abstract] Whitebark pine (Pinus albicaulis) is important for tree island development in some alpine treeline ecosystems in western North America; therefore the effects of an exotic disease on whitebark pine may cascade to ...

 

Inter-relationships between treeline position, species diversity, land use and climate change in the Central Scandes Mountains of Norway

  
Global Ecology and Biogeography Letters, Vol. 6, No. 6. (November 1997), 419, https://doi.org/10.2307/2997351

Abstract

Vegetation samples collected along altitudinal transects through the treeline ecotone in the central Scandes Mountains, Norway, were used to analyse the relationships between species diversity, species turnover and the performance of the tree layer. The study area has a long history of extensive grazing by domestic animals. The floristic composition showed a continuous change along the boreal-alpine gradient. The number of species was more or less constant throughout 600 altitudinal m centred around the treeline, and the floristic similarity between neighbouring ...

 

Rapid recent range-margin rise of tree and shrub species in the Swedish Scandes

  
Journal of Ecology, Vol. 90, No. 1. (February 2002), pp. 68-77, https://doi.org/10.1046/j.0022-0477.2001.00630.x

Abstract

1. Recent elevational range-margin performance of tree and shrub species was studied at a site in the Swedish Scandes. The methods included comparisons of historical and present-day range-margin records (m a.s.l.) in conjunction with age-determination of newly established saplings. 2. Since the early 1950s, the range-margins of Betula pubescens ssp. tortuosa (mountain birch), Picea abies (Norway spruce), Pinus sylvestris (Scots pine), Sorbus aucuparia (rowan) and Salix spp. (willows) have advanced by 120-375 m to colonize moderate snow-bed communities. The non-native Acer ...

 

Spatial structure along an altitudinal gradient in the Italian central Alps suggests competition and facilitation among coniferous species

  
Journal of Vegetation Science, Vol. 19, No. 3. (June 2008), pp. 425-436, https://doi.org/10.3170/2008-8-18391

Abstract

Questions: What is the structure of the anthropogenic upper forest-grassland ecotone and are there differences in the spatial relationships between the tree species involved? Location: Valfurva Valley, Italian central Alps. Methods: We conducted a spatial distribution and structure analysis in three 1-ha permanent plots along an altitudinal gradient, from the treeline to the sub-alpine forest. We reconstructed the age structure from cores from each individual with diameter > 4 cm at 50 cm height. Results: All tree species and age classes ...

 

Altitudinal increase of mobile carbon pools in Pinus cembra suggests sink limitation of growth at the Swiss treeline

  
Oikos, Vol. 98, No. 3. (September 2002), pp. 361-374, https://doi.org/10.1034/j.1600-0706.2002.980301.x

Abstract

Low temperature driven carbon shortage is often assumed to explain slow growth and treeline formation at high elevations. To test this hypothesis, we analysed mobile carbon pools in Pinus cembra across the treeline ecotone in the Swiss Alps. Concentrations of non-structural carbohydrates (NSC) in needles, branches, stems and roots, as well as lipids (acylglycerols) in all woody tissues were measured throughout the growing season. Starch was the most prominent non-structural carbon compound in needles, whereas lipids represented 50-75% of the mobile ...

 

Growth trends and dynamics in sub-alpine forest stands in the Varaita Valley (Piedmont, Italy) and their relationships with human activities and global change

  
Journal of Vegetation Science, Vol. 12, No. 2. (April 2001), pp. 219-230, https://doi.org/10.2307/3236606

Abstract

A study of the forest lines, tree lines and the structures of the sub-alpine forest was performed in Vallone Vallanta and in Alevé forest in the Varaita Valley (Cottian Alps, Piedmont, Italy). Forest- and tree lines were analysed over 1728 ha while forest structures were studied on six 3000-m2 plots located at the tree line (2), at the forest line (2) and inside the sub-alpine forest (2). Dendro-ecological analysis of living plants and stumps showed that Larix decidua was more abundant ...

 

Tree line population monitoring of Pinus sylvestris in the Swedish Scandes, 1973–2005: implications for tree line theory and climate change ecology

  
Journal of Ecology, Vol. 95, No. 1. (2007), pp. 41-52, https://doi.org/10.1111/j.1365-2745.2006.01190.x

Abstract

* 1Demographic trends of Pinus sylvestris L. (Scots pine) tree line populations are reported for a 32-year monitoring period (1973–2005). Functional and projective aspects of tree line performance were analysed by relating temporal variability and change of vital population parameters, such as natality/mortality, vigour, injuries, height growth and seed viability to contemporary variations in air and soil temperatures. * 2The size of the entire sampled population increased by 50% during the 32-year observation period and thereby pine has become a more ...
